Beijing releases key air pollution data; early results seem low compared to US Embassy results

By Associated Press, Published: January 21

BEIJING — Caving to public pressure, Beijing environmental authorities started releasing more detailed air quality data Saturday that may better reflect how bad the Chinese capital’s air pollution is. But one expert says measurements from the first day were low compared with data U.S. officials have been collecting for years.

The initial measurements were low on a day where you could see blue sky. After a week of smothering smog, the skies over the city were being cleared by a north wind.

The readings of PM2.5 — particulate matter less than 2.5 micrometers in size or about 1/30th the average width of a human hair — were being posted on Beijing’s environmental monitoring center’s website. Such small particulates can penetrate deep into the lungs, so measuring them is considered a more accurate reflection of air quality than other methods.

It is the first time Beijing has publicly revealed PM2.5 data and follows a clamor of calls by citizens on social networking sites tired of breathing in gray and yellow air. The U.S. Embassy measures PM2.5 from a device on its rooftop and releases the results, and some residents have even tested the air around their neighborhoods and posted the results online.

Beijing is releasing hourly readings of PM2.5 that are taken from one monitoring site about 4 miles (7 kilometers) west of Tiananmen Square, the monitoring center’s website said Saturday. It said the data was for research purposes and the public should only use it as a reference.

The reading at noon Saturday was 0.015 milligrams per cubic meter, which would be classed as “good” for a 24-hour exposure at that level, according to U.S. Environmental Protection Agency standards. The U.S. Embassy reading taken from its site on the eastern edge of downtown Beijing said its noon reading was “moderate.” Its readings are posted on Twitter.

Steven Andrews, an environmental consultant who has studied Beijing’s pollution data since 2006, said he was “already a bit suspicious” of Beijing’s PM2.5 data. Within the 24-hour period to noon Saturday, Beijing reported seven hourly figures “at the very low level” of 0.003 milligrams per cubic meter.

“In all of 2010 and 2011, the U.S. Embassy reported values at or below that level only 18 times out of over 15,000 hourly values or about 0.1 percent of the time,” said Andrews. “PM2.5 concentrations vary by area so a direct comparison between sites isn’t possible, but the numbers being reported during some hours seem surpisingly low.”

The Beijing center had promised to release PM2.5 data by the start of the Chinese Lunar New Year on Monday. It has six sites that can test for PM2.5 and 27 that can test for the larger, coarser PM10 particles that are considered less hazardous. The center is expected to buy equipment and build more monitoring sites to enable PM2.5 testing.

Beijing wasn’t expected to include PM2.5 in its daily roundups of the air quality anytime soon. Those disclosures, for example “light” or “serious,” are based on the amount of PM10, sulfur dioxide and nitrogen dioxide in the air.

Beijing interprets air quality using less stringent standards than the U.S. Embassy, so often when the government says pollution is “light,” the embassy terms it “hazardous.”

“There has been tremendous amounts of attention in the Chinese media — whichever newspaper you pick up, whichever radio station you listen to, channel you watch — they are all talking about PM2.5 and how levels are so high,” said Andrews.

“What has been so powerful is that people are skeptical, and I think rightly skeptical,” about the government’s descriptions of data, he said.

Beijing begins PM2.5 measure of air quality

Updated: 2012-01-21 15:56


BEIJING – Beijing’s environment authority on Saturday launched the much-anticipated PM2.5 measure of air quality, fulfilling its promise of publishing the data ahead of the Spring Festival holiday, which starts on Sunday.

The Beijing Environment Protection Monitoring Center said its monitoring station at the city’s second ring road had detected 0.003 micrograms of PM (particular matter) 2.5 per cubic meter, suggesting the air quality is good.

The PM2.5 gauge is considered stricter than Beijing’s previous standard of PM10, as it monitors “fine” particles 2.5 microns or less in diameter.

A fierce online public debate on PM2.5 and PM10 began at the end of 2011 when it came to light that air-quality monitoring results released by Beijing’s weather forecast station and the US Embassy in Beijing often differed.

On Saturday, the embassy’s air-quality rating also suggested the air is “good.”

Zhao Yue, deputy head of the Beijing Environment Protection Monitoring Center, said cold air from Friday helped blow away “hazardous” pollution persisting in the air due to week-long smoggy weather.

However, he pointed out Saturday’s PM2.5 reading can only vouch for air quality in Xicheng district, where the city’s only PM2.5 monitoring station was set up.

He said local authorities plan to build a citywide network of PM2.5 monitoring stations by the end of this year.

Zhao did not give the exact number of stations to be built. But the city currently has set up 27 PM10 monitoring stations to provide real-time data covering in the whole city.

Yu Jianhua, an air official with the Beijing Environmental Protection Bureau, said the city government has spent 10 years taking aggressive air pollution control measures, including eliminating heavy-polluting vehicles and using clean energy for heating, in the hope of meeting the national PM10 standard of 100 micrograms per cubic meter of air. However, the average PM10 reading last year still hung at 120 micrograms.

Although the national standard on classifying the PM2.5 reading has yet to come out, public hearings by China’s environment ministry earlier this month suggested the future national PM2.5 standard may be set at 35 micrograms per cubic meter of air on average a year.

Yu said PM2.5 on average accounts for less than half of the PM10 concentrations. It means, under the present air-quality conditions, Beijing’s average PM2.5 rating could not meet the pending national standard.

He said research showed that 50 percent of the total PM2.5 particles in the air are contributed by automobile exhausts, and another 23 percent are brought by floating dust.

Beijing’s geological situation means that air pollution is likely. The city sits in a plain area surrounded by mountains in three sides, Yu explained.

He said the municipal government has laid down a series of measures to tighten air-pollution control. Among them, a primary target is to introduce a Euro 5 emission standard to replace the current Euro 4 by the end of the year pressuring auto makers to upgrade products to reduce emission discharge.

Beijing has 5 million vehicles on road, meaning urban traffic is very congested. Experts say vehicle emissions contain more fine particles when automobiles drive at low speed.

Hong-Kong : La pollution menace la capitale de la finance

Selon le département de protection de l’environnement, la pollution à Hong-Kong a été la pire de l’histoire pendant l’année 2011. Un véritable problème pour l’ancienne colonie britannique qui voit les cadres de la finance internationale partir pour Singapour à cause de cela. Un changement serait-il possible?

Les trois stations principales de mesure de la pollution le long des routes ont indiqué un niveau supérieur à 100 pendant 20% de l’année 2011. Un tel niveau signifie qu’au moins un des principaux polluants mesurés dépasse la limite réglementaire maximale. La situation est 10 fois pire qu’en 2005, où le niveau 100 n’avait été atteint que pendant 2% de l’année.

Un parc automobile très polluant

Si les hongkongais ont l’habitude d’accuser les usines du voisin communiste chinois, force est de constater que la pollution est aussi une affaire locale. Les niveaux de pollution sur l’ensemble des stations de mesure, et non plus seulement sur les trois principales, sont stables. Or les stations de mesure des nouveaux territoires, les plus proches de la république populaire de Chine, sont beaucoup plus représentatives de la pollution héritée des usines de la province du Guangdong en république populaire.

Alors, à qui la faute? Selon le département de protection de l’environnement, c’est l’âge moyen des véhicules en circulation et l’augmentation de leur nombre qui est à l’origine du problème. Pour y remédier, le gouvernement va installer des pots catalytiques sur les bus les plus anciens. Une mesure assez anecdotique qui ne va pas réconcilier les ONG environnementales avec l’administration.

Une politique environnementale très permissive

En effet, selon plusieurs de ces ONG, le gouvernement a volontairement retardé l’introduction de nouveaux standards de qualité de l’air, afin de pouvoir tranquillement mener à bien ses grands travaux d’infrastructure. Au nombre desquels on compte une nouvelle piste pour l’aéroport (la troisième) et des usines d’incinération des déchets. Selon James Middleton, de l’ONG ‘Clear the Air’, cette politique permissive en matière de pollution vient de très haut:

les fonctionnaires du département de protection de l’environnement ont aussi des enfants qui partagent le même air que nous. Cette politique vient clairement de décisions prises au sommet de l’administration. C’est une forme de mépris et de manque d’égards à la population de la part d’une administration dont l’un des devoirs primordiaux est d’assurer la bonne santé des citoyens.

Toujours est-il que l’administration pourrait avoir à se pencher très rapidement sur le sujet de la pollution de l’air. Plusieurs multinationales de la finance ont déplacé leurs QG Asie de Hong-Kong vers Singapour, qui dispose des mêmes avantages pour les banquiers (économie ouverte, personnel qualifié et multilingue, …) que Hong-Kong sans ses inconvénients : la qualité de l’air y est bien meilleure. Pour une cité qui abrite les sièges de HSBC ou Standard Chartered, la finance est une industrie trop importante pour ignorer des facteurs qui pourrait la faire fuir. Si le maintien de son statut de capitale asiatique de la finance passe par la réduction de la pollution, il est fort à parier que la nouvelle administration de Hong-Kong qui sortira des urnes pendant cette année 2012 saura y apporter le soin nécessaire


Hong Kong: The pollution threatens the finance capital

According to the department of environmental protection, pollution in Hong Kong was the worst in history during 2011. A real problem for the former British colony that sees executives from international finance to Singapore because of this. A change would be possible?

The three main stations for measuring pollution along roads indicated a level higher than 100 for 20% of 2011. This level means that at least one of the main pollutants measured exceeds the statutory maximum. The situation is 10 times worse than in 2005, when the level had reached 100 for only 2% of the year.

A highly polluting fleet

If Hong Kong were used to accuse the Chinese Communist neighbor’s plants, it is clear that pollution is a local matter. Pollution levels on all stations, and not only on the three main stable. Now the measuring stations of the New Territories, closest to the People’s Republic of China, are much more representative of the inherited pollution plants in Guangdong Province People’s Republic.

So, whose fault? According to the department of environmental protection is the average age of vehicles on the road and increasing the number that is causing the problem. To remedy this, the government will install catalytic converters on older buses. A fairly anecdotal wrong reconcile environmental NGOs with the administration.

Environmental policy very permissive

According to many of these NGOs, the government deliberately delayed the introduction of new standards for air quality in order to quietly carry out its major infrastructure projects. Among which include a new runway to the airport (the third) and waste incineration plants. According to James Middleton, of the NGO ‘Clear the Air’, this permissive policy on pollution is very high:

officials of the department of environmental protection also have children who share the same air as us. This policy is clearly top-level decisions of the administration. It is a form of contempt and disrespect for the people from administration, one of whose primary duties is to ensure the health of citizens.

Still, the administration may have to look very quickly on the subject of air pollution. Several multinationals have moved their headquarters finance Asia Hong Kong to Singapore, which has the same benefits for bankers (open economy, skilled and multilingual, …) that Hong Kong without its drawbacks: the air quality is much better. For a city that houses the headquarters of HSBC and Standard Chartered, the finance industry is too important to ignore factors that could cause it to flee. While maintaining its status as capital of the Asian financial means reducing pollution, it is likely that the new administration in Hong Kong that exit polls during the year 2012 will make the necessary care.
