Scientists examine the health risks of Hong Kong’s notorious ‘street canyons’

Findings will help urban planners minimise impact of air pollution on residents

Hong Kong’s notorious “street canyons” have become the latest research subject for a group of the world’s top scientists specialising in air pollution and health.

Researchers from Britain, Canada and Hong Kong are conducting a three-dimensional air quality study in the city, which has a unique urban morphology – a dominance of high-rises and a close proximity between the population and traffic.

The study will not only map the three-dimensional movement of air pollutants, but also try to relate the pollution levels to the health of residents living at various heights in high-rises.

It will assist urban planning and building designs to minimise pollution impacts in Hong Kong and other megacities across Asia.

The street canyon effect is often cited as one of the factors in Hong Kong’s worsening air pollution. Closely built high-rises with heavy traffic in between are blamed for blocking ventilation and trapping air pollutants.

Funded by the Health Effects Institute in the US, the 30-month study will be jointly carried out by scientists from King’s College London, University of Hong Kong, the University of British Columbia and Simon Fraser University in British Columbia.

The study consists of two parts. The first, which started in March, collects spatial air pollution data from 100 selected sites across the city. The scope of the pollutants includes fine particles, as well as nitrogen oxides and black carbon.

The second part is to identify suitable canyon sampling sites to measure vertical pollution exposure. Small sensors capable of recording pollutant concentrations as well as weather data will be installed on buildings.

Dr Benjamin Barratt, of the environmental research group at King’s College London, who described Hong Kong as an ideal “urban laboratory”, said they had selected estates in different districts to represent varying characters of street canyons.

He said the first-phase vertical monitoring in Mong Kok, Jordan, Choi Hung and Sai Wan had been completed and participants from two more districts – North Point and Hung Hom – were now being recruited.

He did not want to disclose the estate names, however, as he feared it might mislead the public into thinking that they must be pollution hotspots.

He said two sets of four monitoring units had been mounted on the exteriors of the selected buildings at four height levels. Another two sets are installed inside homes to examine the extent of pollution infiltration.

“We are assessing how pollution emitted from vehicles is trapped inside street canyons, how this changes with height and how much enters the homes of residents,” he said. “Our study is primarily concerned with mapping the level of risk to public health, but these questions are also important for city planners.”

He said the study results would help planners design buildings that minimised the impact of air pollution on the health of residents.

Barratt said they would also launch a study “relating hospital records of specific diseases with patients’ home addresses, including floors”.

Dr Wong Chit-ming, associate professor at HKU’s School of Public Health, who is taking part in the study, said the research was the first and “most systematic” ever done in a city.

Wong said the results could provide more understanding about the dynamics between pollution levels and heights.

“The higher the altitude, the less the air pollution should be. But the situation might be far more complicated than that, as city layouts and wind directions have an impact, too,” he said.

A spokeswoman for the Environmental Protection Department said: ” The dispersion of air pollutants in street canyons is a complex physical phenomenon that the scientific community, including ourselves, has been trying to better understand.

“The research project of King’s College will surely help advance scientists’ understanding of this complex physical phenomenon.”

Clean Air Network chief executive Kwong Sum-yin welcomed the research project as it would provide much-needed urban pollution analysis and modelling on a more micro, rather than a macro, scale.

Villagers in northern Lantau destroy mangrove in protest over potential restrictions

Monday, 25 August, 2014

Ernest Kao

Dozens of villagers in northern Lantau chopped down a mangrove near an ecologically sensitive bay yesterday to protest against a government move to zone areas on the fringes of their villages as protected land.

Excavators were brought in to raze trees, while machete- and hoe-wielding villagers chopped down shrubs on the coast of Tai Ho Wan, which is known for its oyster-rich mudflats and horseshoe crabs.

Together with the three rivers that feed it, Tai Ho Wan is now designated as a Site of Special Scientific Interest (SSSI), but not yet zoned as such. Statutory planning rules would ensure government departments give due consideration to conservation if the proposal was approved later this year.

But indigenous villagers of the San Heung community, which includes Pak Mong, Ngau Kwu Long and Tai Ho villages, fear their rights to farm and build small houses will be restricted if the restrictive development plans are agreed to.

“Step by step, the government has been depriving us land owners of our rightful use of land, which was originally designated for agricultural use,” the community said in a declaration in which they also demanded to meet the development and environment ministers.

They blamed construction of the North Lantau Highway in the 1990s for blocking discharge from the river and flooding coastal farmland. The indigenous villagers said in their declaration that the government had “bullied” them again in 1999 with the SSSI designation.

“All we want is to return our farmland to agricultural use without any prior conditions,” said Ngau Kwu Long village spokesman Lam Chu. “You can’t just take away our land without our consent or compensation.”

Heung Yee Kuk vice-chairman Daniel Lam Wai-keung showed up to support the villagers’ protest yesterday.

Green groups were outraged at the destruction of the mangrove. “I’m furious. This is disrespectful,” said Eddie Tse Sai-kit of the Save Lantau Alliance. “If they really cared for the land and wanted to farm it, then they would not do such as thing.”

Tse said most of the private land in the enclave had been sold to developers in the 1990s.

“It is worth questioning whether they’re really doing this for the right to build small houses,” he said.

Under an interim development plan covering 230 hectares, gazetted in March, the villages’ development zones are limited to 1.27 hectares, which the villagers say constrains their right to build small houses.

“It’s a lie … Most villagers just want to transfer their small-house rights for a profit,” said Green Sense president Roy Tam Hoi-pong. “If they wanted to farm they would have done so long ago.”

Department failing to stop pollution of pristine Hoi Ha Wan

Monday, 25 August, 2014

I refer to the report (“Tai Po beach clears court hurdle [1]”, August 13). Why does the government rush ahead with this project when water quality in existing beaches is deteriorating?

I refer specifically to Hoi Ha Wan. I have been swimming there regularly since 2006 and the water has always been crystal clear. Since 2014, its shallow waters have turned markedly murky and foamy.

Most of the farmland in Pak Sha O village, adjacent to a stream that feeds into Hoi Ha Wan, has been bought by developers.

The Lands Department is more agreeable to approving village house applications on cultivated farmland. Therefore, land at Pak Sha O is being farmed for vegetables. I suspect there is massive use of chemical fertilisers and pesticides, which is now finding its way to Hoi Ha Wan via the stream. This may have caused a rapid deterioration of seawater quality.

A high standard of water quality in Hoi Ha Wan must be maintained for at least two reasons.

First, about 100,000 people use it and its beaches for recreation annually. The government should have the health of these people at heart.

Second, the biggest and prettiest coral colonies in Hong Kong are found there and the surrounding seas. This is one of Hong Kong’s irreplaceable treasures. Corals are extremely sensitive to chemicals. Adding more toxic chemicals and waste products to Hoi Ha Wan waters will impact on marine life negatively.

The Agriculture, Fisheries and Conservation Department declined to have the near-shore water quality checked, because it has subcontracted the work of monitoring Hoi Ha Wan water quality, until March 2015, to a third party.

The department should have located the monitoring station closer to shore and corals where it matters, but it was located one kilometre away.

The future looks dire for Hoi Ha Wan and Hoi Ha Wan Marine Park. Recent outline zoning plans show more village houses will be located close to streams and shoreline.

These locations are much sought after by developers for their scenic value. Without central sewage treatment, chemicals and grey water from new houses will reach Hoi Ha Wan. In time, it could be renamed Hoi Ha sewage pit.

Village house development is lucrative. This creates pressure on government departments to “facilitate” by bending their own rules. We must remain vigilant to protect our country and marine parks.

Experts slam lack of novel ideas to protect white dolphins from third runway construction

Tuesday, 19 August, 2014

Government advisers express exasperation at Chek Lap Kok officials’ lack of fresh thinking on protecting dolphins if third runway is built

Government environment advisers vented their frustration yesterday at the Airport Authority’s failure to come up with “out-of-the-box ideas” to protect the threatened Chinese white dolphin during construction of the proposed third runway.

They were speaking on the last of three days’ scrutiny of the environmental impact assessment study on the runway.

“We hear nothing new. You just repeat and repeat,” said Dr Hung Wing-tat, vice-chairman of the Advisory Council on the Environment subcommittee studying the report.

“You just can’t say let [the environmental impact] study pass first and we will see what we can do. Can you invest a little bit more? And don’t always just ask the government to do things.”

Subcommittee members had been unhappy at the last meeting over the lack of measures to compensate for plans to reclaim 650 hectares of prime habitat for the shrinking dolphin population – and it emerged as the key issue again yesterday.

The meeting was the last opportunity to provide new information to the subcommittee before it makes its recommendations to the council, which will decide next month whether the report should be endorsed and what conditions to attach.

Before Hung’s criticism – which was met by silence from airport officials – Professor Nora Tam Fung-yee also vented her frustration at the authority’s performance.

She criticised it for failing to respond to members’ previous call for “out-of-the-box ideas”, such as setting up another marine park farther from the works site in southwestern Lantau.

The authority proposes opening a 2,400 hectare marine park after the runway is finished, saying dolphins that leave the area during construction will return.

Tam also queried the effectiveness of a proposal to re-route the Skypier high-speed ferries to Macau and the Pearl River Delta and lower their speed during the construction.

The measure would re-route ferries travelling to the north of Lung Kwu Chau marine park – a vital dolphin sanctuary. The authority also proposes to freeze further growth until 2023 of its ferry business that carries 2.5 million transit air passengers a year.

Authority consultant Eric Ching Ming-kam said the diversion of the ferries and their lowered speed could benefit the dolphins by reducing underwater noise without significantly reducing passenger comfort.

But Tam said the increased journey times might increase the dolphins’ exposure to noise and demanded a proper assessment.

Another member, Gary Ades, listed a number of other options, including relocating the Skypier. But his idea was rejected by the authority as not practical.

Under present plans, the new 2,400-hectare marine park would connect the existing Sha Chau and Lung Kwu Chau Marine Park with the planned Brothers Islands marine park.

Another consultant, Dr Thomas Jefferson, said in June that some decrease in dolphins was to be expected during construction, “but the plan and hope” was that the large marine park would draw them back.

Burnabynow: Incinerator creates toxic mess for region

from Hildegard Bechler of New Westminster, published on Burnabynow:

An incinerator fouls not only our airshed, with thousands of unknown toxins and a ton of greenhouse gases for every ton burned.  It fouls our rivers, lakes, and groundwater.  Toxic ash landfills foul the soil (25 per cent of our waste – by weight, 10 per cent by volume – remains as toxic ash).  Incineration fouls our health.  Only the unknowable toxic synergies are “unpredictable”; the other impacts are a sure thing.

The Fraser Valley Regional District is only one of many local governments opposing the incinerator: one-third of Metro Vancouver directors voted against it.  Native Nations, community organizations and hundreds of individuals in both regions opposed it.

An incinerator would burn our kids’ resources, waste their fossil fuels, for 50 years.  Long before 2070, the Earth’s 10 billion people will be desperate for resources. Products that are difficult to recycle will be a folly of the past.  Like the costly destruction systems Metro Vancouver is now building, which will be shut down – wasted.  Will our grandchildren have to mine landfills, fish the Pacific gyre?

Metro’s own waste plan (financial implications, page 32) points out that diverting resources from the waste stream has economic benefits.

“There is considerable economic activity that takes place in the process of recycling the collected materials into new goods as an alternative to virgin feed stocks.  Although difficult to estimate, the economy associated with the remanufacturing of recycled materials into new products exceeds the costs for collection, transportation and processing.  Net expenditures associated with disposal more closely reflect the entire disposal economy since there is little economic activity that occurs following disposal.”

So why choose incineration?  Metro Vancouver’s plan states that we can’t recycle more than 80 per cent unless distant markets remain stable; that they are looking for contingencies.  Asian markets fail when the price of oil gets too high, as happened in 2008 when we had to pay to burn or bury our recycled materials.

What contingency could there be besides local remanufacture?  According to Metro Vancouver’s director of policy and planning for waste management in 2011, “The contingency is waste-to-energy”.  (Global incinerator corporations have deep pockets, plenty lobbyists.) This raises the question: what happens to the 80 per cent we’ll be recycling when markets fail?

It pays Asian corporations to buy, ship and remanufacture our recovered resources and ship new products back.  These are cheaper not only because of low wages and poor to no environmental protection.  These industries avoid the cost of extracting and refining virgin resources.

Instead of wasting billions of our tax dollars on massive systems for burning, on garbage transport and ash landfills, we need to use public money to develop diversion and remanufacturing capacity today: to build industries, business, jobs: local economic renewal, for public and private profit.

Metro Vancouver taxpayers can own a paper recycling plant and other remanufacturing industries, the way we own the incinerator.  We can partner with private industry and municipalities as we do with the Cache Creek landfill.  We can work with private recycling industries and publicly owned facilities too, to meet everyone’s needs for resources, as we already do with the various waste management companies.

Each municipality can build a bottle washing plant; facilities to convert textiles to rags and paper, construction waste to lumber, firewood and wood chips, demolition waste to product recovery and building deconstruction.  Reuse and repair community centres for appliances, furniture, bikes, can include a free store to make items available to people who can’t afford even thrift stores, taking the social justice dimension of waste into account.

Diversion options are virtually unlimited.  Most such developments are profitable industries and businesses.  Some cost the region (as does incineration) but are profitable in the long run because they conserve resources and share our wealth-ethical imperatives.    All are better outcomes for our taxes than toxic ash and destruction of our life support ecosystems.

This necessary reconfiguration of our industrial consumer society is happening all over the world.  It can happen here.   We can profit today by protecting our children’s future.

IPS: Dioxin Levels Soar on Icelandic Farms (2011)

by Lowana Veal, for the Inter Press Service:

In the northwestern Icelandic town of Isafjordur, milk is causing pandemonium. A local milk marketing board recently tested one farm’s milk for the presence of harmful chemicals. Dioxin, and dioxin-like compounds, were found to be present in amounts higher than the recommended maximum levels, threatening the future of local farmers, and angering residents.

Dioxins are highly toxic compounds produced as a byproduct in some manufacturing processes, notably herbicide production and paper bleaching. They are a serious and persistent environmental pollutant.

The milk that was tested came from a farm called Efri-Engidalur, located in a valley only 1.5 kilometres from a waste-burning incinerator that was closed by the authorities last year due to consistently high levels of pollutants.

“Usually, measurements are done by the authorities, but we decided to test for dioxin because we were concerned about the incinerator,” said Einar Sigurdsson, of MS Iceland Dairies.

As a result of the findings, the Icelandic Food and Veterinary Authority (IFVA) decided to test samples of milk, meat, and hay from several farms in the surrounding area.

The findings revealed increased levels of dioxin and dioxin-like compounds in the majority of the samples. Dioxin-like compounds are polychlorinated biphenyls, commonly known as dioxin-like PCBs, which behave like dioxin, so are generally classified with it in terms of toxicity.

SCMP: Hong Kong’s professions must not be protectors of their own privilege

by Philip Bowring, published in the SCMP:

Hong Kong people are familiar enough with the power as well as wealth of the city’s landed aristocracy. Less obvious is the privileged position of leaders of some of the so-called “learned professions” – lawyers, accountants, doctors and the like.

Like guilds in medieval Europe that were created to enforce standards of workmanship and training on craftsmen such as weavers and goldsmiths, they have become over time as interested in protecting themselves from competition and keeping out new ideas as in looking after their clients. The Hong Kong Institute of Certified Public Accountants cannot be accused of overly restricting membership or imposing unreasonable entry requirements. But, not for the first time, its willingness to take prompt action in cases involving prominent members accused of misconduct is in question.

On December 24, it finally announced a decision in the case of Anthony Wu Ting-yuk, until recently chairman of the Hospital Authority and previously chairman of auditing giant Ernst & Young, the Hong Kong General Chamber of Commerce and the government-allied think-tank the Bauhinia Foundation – among a myriad other posts.

Wu was found guilty of professional misconduct relating to his involvement in New China Hong Kong Group, which collapsed in 1999. It then took 14 years for the institute to investigate and finally come to a decision on what, on the face of things, was not a very complicated case. It did so only after Wu had stepped down in November from the Hospital Authority and announced it on a day which ensured minimal media coverage. Wu received his top appointments despite the cloud hanging over his professional integrity.

It is better in principle that professional bodies police themselves rather than having governments impose themselves. But the Wu case leaves one asking whether anything has improved since the then Society of Accountants failed to act against Price Waterhouse in the case of the Carrian Group collapse. Price Waterhouse was Carrian’s auditor and its senior partner became managing director of Carrian.

Another accountant long showered with official appointments has also recently been in the news – Marvin Cheung Kin-tung. A former chairman of auditors KPMG and of the Society of Accountants (the previous name of the Institute of Certified Public Accountants), he is currently chairman of the Airport Authority, a member of several boards including HSBC and Hong Kong Exchanges & Clearing, and a former Executive Council member.

Cheung is rightly engaged in the debate over the third runway – though one might feel that coming from the private sector he would expect it to be funded commercially rather than from the public trough. But it was surprising to see someone in such a position with a public body make a big media splash defending the inordinate land lease privileges of the Hong Kong Golf Club.

For sure, as president of that club, he wants those privileges maintained. But his dual roles are another classic example of how some private-sector leaders have become installed deep inside government and can influence public affairs for private advantage. His comments on golf have also drawn attention to the existence of a private course on Airport Authority land, the little-known nine-hole course close to Terminal 2.

The elite golfers who cling to the claim that Hong Kong needs three courses at Fanling and spurn alternatives such as on Kau Sai Chau might get some sympathy if they ever used their position in or near government to spend real money on public sporting facilities, particularly for schools. The abysmal standards of fitness of young people, as revealed by recent surveys, is as much due to the lack of facilities as parental obsession with book learning and fears that sport leads to injuries. Public needs are not met by building a showpiece stadium.

Now we are told not to exercise as the air is too foul. Endless government expressions of worry about the costs of health care are nothing but hypocrisy until it invests in the prevention of disease – starting with clean air and opportunities for physical activity.

Another contribution to public health – and one with no cost at all – would be to take on the doctors’ lobby and allow foreign-trained doctors (and nurses) to practise here.

As revealed this past week, mortality rates in several public hospitals are far higher than they should be in a city with Hong Kong’s wealth and technical abilities. Shortages of beds, particularly in intensive care units, is one reason but staff shortages are even more to blame. Yet Hong Kong’s political system, which enshrines every principle of vested interest, ensures that it cannot easily benefit from foreign-trained doctors.

High-quality professional service is a major part of Hong Kong’s appeal. But it will not be sustained in the longer run if the professions are protectors of privilege rather than standards, and their prominent members are seen as part of the small group of mutual back-scratchers who turn up on every major private-sector board and government statutory and advisory body. The corporate state is the antithesis of Hong Kong’s spirit of entrepreneurship and social mobility – and of independent professions.

Scotland’s Zero Waste Plan

The Scottish government released a‘Zero Waste Plan’ in 2010, outlining an organised scheme for achieving zero waste production over 10 years. Readers will find special emphasis on presorting waste and banning materials from landfills, development of infrastructure for recycling, and, most importantly, recognising the importance of businesses participating in the effort.

SCMP: Plover Cove country park expansion could lead to showdown

from Cheung Chi-fai of the SCMP:

Officials have quietly drafted proposals to expand at least one country park that would limit the building rights of villagers.

The proposal for incorporating five enclaves into the Plover Cove Country Park in the northeastern New Territories would add 60 hectares to the 4,600- hectare park.

The Agriculture, Fisheries and Conservation Department plan comes just a few weeks after development minister Paul Chan Mo-po provoked a heated debate by suggesting houses might be built in the parks. The new proposal is likely to prove just as controversial.

AFCD officials say the five areas, either surrounded by or jutting into the park, are suitable for incorporation in full or in part. This would presuppose that development in the parks was not favoured. Any construction, including small houses for indigenous inhabitants, would require approval from the Country and Marine Parks Board.

people should think on why the HKZHM bridge came about
Zhuhai airport was not allocated any international destinations
HK Airport Authority owns 55% of the company which operates Zhuhai airport
So the bridge will bring export airfreight from Zhuhai to Chep Lap Kok
a second reason for building the bridge is ……………………………. ?

“Think big”….there was an article in the press about Singapore’s “think big” plans and one element would be applicable to HK: Singapore will move its container port to a more remote area and build a new city in the current location. Why not move Kwai Chung container port to China, where it belongs, and build a new city there? We could have another Taikoo Shing (Kwai Chung Shing?) located close to the major employments areas and with infrastructure in place. Why build a new Shatin in the remote NT when we can build a new town in a better location?

Integrating airports, not another runway, is long-term solution

Comment› Letters

I agree with your editorial (“Stop bickering and think big [1]“, August 20) as Hong Kong has moved down through the gears since the 1997 handover, and it seems that we are now driving with the handbrake on, despite our powerful fiscal position.

The Kai Tak site offered an opportunity to think big, but our cruise terminal is underwhelming. The grand vision of the Central waterfront is already a disappointment.

West Kowloon’s woodland park shows no signs of life. Our competitors such as Shanghai and Singapore would have implemented significantly more at these unique and dramatic locations. Hong Kong has lost its confident wide vision, and now bureaucratically seeks blinkered reactive solutions. The transport situation in the Pearl River Delta also illustrates this view.

The Hong Kong-Zhuhai-Macau bridge is catering only to narrow vested interests. The present push for a third runway at Chek Lap Kok is an easy orthodox response but avoids having to think outside the box. There is ample aircraft runway capacity in the delta region but a severe shortage of airspace.

It is the most congested airspace in China: besides Chek Lap Kok, Guangzhou Baiyun, Shenzhen Baoan, Zhuhai Jinwan, and Macau airports are competing for this space. It is a case of “one country, five airports”, and despite official pledges of co-operation and the signing of a memorandum of understanding in 2011 there appears little movement to control airspace centrally.

In the delta region, each airport is “paddling its own canoe”. If London acted in this unco-ordinated manner with City, Gatwick, Heathrow, Luton, Southend and Stansted airports there would be air traffic chaos. It is common sense to closely integrate Chek Lap Kok, Macau, Zhuhai, and Shenzhen under a single management. Just adding runway capacity at Hong Kong is not a solution. Public transport needs must trump private commercial interests.

It should have been a “no-brainer” to extend our Airport Express line to these three airports, but ludicrously the Hong Kong-Zhuhai-Macau bridge only serves road traffic – contrary to government policy of giving precedence to rail.

We need a rapid and secure transport system to whisk travellers between these four airports. Instead of spending billions of dollars on the ecologically damaging reclamation for a third runway, authorities should invest into the vanguard of Elon Musk’s “Hyperloop” high-speed-transit system. The pneumatic tube ferrying the passengers could be mounted on the Hong Kong-Zhuhai bridge. It would also create some excitement about Hong Kong as we become increasingly dull.
