What needs more attention in this (cautiously optimistic) image of a general trend of decreasing concentrations of air pollutants in China is, for instance, the highly uneven distribution of pollution exposure. A6. While China is home to some of the most polluted cities on earth, there are substantial differences across the country, due to varying emission intensity, meteorological conditions, and the impact of dust storms. Consequently, air pollution in Beijing, especially fine particulate matter (PM 2.5) pollution, has gradually become a severe environmental issue, due to the continuing growth in energy consumption and the resulting multiple pollutant emissions. Bi, Yujie still above the Chinese air quality standard of 35g/m3). Lyu, Shoujun Beijings population has swelled from 11 million to 16 million in just 7 years, and has doubled over the past century.

Almost the entire world breathes air that exceeds the World Health Organizations air-quality limits at least occasionally. J., & Diamond, J. Also, secondary particles (which are mainly in the PM2.5 fraction) seem to be playing an increasingly more important role.Footnote 52 These features are linked to the fact that technologies that reduce emissions of primary particles have become more common in power plants and industries in China, whereas technologies and policies to reduce particle precursor gases (SO2, NOx, NH3, and VOCs (Volatile Organic Compounds) have not yet reached the same coverage. Romano, Giulia Tao, Wei The concept of the Air Pollution . Last year, nine of the 10 cities with the highest annual average of fine particulate matter were in Asia including six in India, according to air quality company IQAir, which aggregates readings from ground level monitoring stations worldwide. 54 Greenpeace 2016. 2020. a PM10 concentration of 160340g/m3.Footnote 41 In comparison, in Shijiazhuang, the highest daily mean PM10 concentration recorded during January 2013 was 1222g/m3, whereas the annual mean PM10 was 305g/m3 in 2013. Reference Zhang, Wang, Wang, Cao, Wang and Ye2015. An additional 0.07 million deaths were attributed to ambient ozone exposure. Furthermore, the metric for measuring PM has changed over time (from TSP (Total Suspended Particulates) to PM10 (see Figure 3) and only since 2013 is PM2.5 monitored on a regular basis and mainly in urban districts. As discussed below, estimates of population-weighted exposure to ambient air pollution in China are becoming increasingly more robust due to the rapidly expanding urban PM2.5 monitoring network and the opportunity to use satellite data. Beijings Air Quality Improvements Are a Model for Other Cities. Climate & Clean Air Coalition, Climate & Clean Air Coalition, 09 Mar. 45 Vellingiri et al. As a pollution phenomenon, haze is not an unambiguous term, however, and studies attempting to describe the sources and physio-chemical nature of haze episodes in Chinese cities show a varying picture depending on place and time. Air quality becomes hazardous for sensitive groups in the orange zone, with an AQI from 101-150. In eastern China, both wind speeds and precipitation have shown an overall decline, thus the area is now more prone to smog than it used to be.Footnote 55 In 2015, low wind speeds and high relative humidity probably also contributed to the bad air quality in Beijing in the last two months that led to the capital's first-ever red alert for air pollution, prompting schools and factories to close and restrictions on vehicle use to be put in place. Fu, Pingqing The export-linked emission growth over the period corresponded to half the total emission in EU-27 countries in 2010.Footnote 48.

Reference Wang, Tao, Balkanski, Ciais, Boucher, Liu and Piao2014. If we assume that the PM10/BS-ratio is between 0.61.26,Footnote 40 this implies that the daily mean PM10 level averaged for all 12 monitoring stations in London in December 1952 reached 10002000g/m3 on the worst days (and between 27005700g/m3 in Central London).

Liu, Jianing 8 Hansen and Liu Reference Hansen and Liu2017 (this issue). Photograph by Nicol Lazzati, 2009. In most developed countries, the annual mean population-weighted exposure to PM2.5 has steadily decreased. Typically, low wind speed and high relative humidity are smog-prone conditions. New Jersey's air quality was worse Tuesday night than some cities that consistently have the worst air pollution in the world. We, Yahoo, are part of the Yahoo family of brands. Chinese media say that although some of the smog can be . In other words, the annual average levels of particulate pollution in China's most polluted cities may be on par with London in the early 1950s, and the peak values in recent episodes, while generally being lower, may possibly have touched the levels of the December 1952 London smog. Regarding the Los Angeles smog, the ozone (O3) levels in Los Angeles were far above what is currently reported in China. April 3, 2013.

Winds from the Gobi desert are also blown towards Beijing hence bringing dust particles into the city that end up complicating the air pollution problem in Beijing (Zhang, 2005 in Schipani, 2021). For instance, the highest daily mean SO2 level in Shijiazhuang in the severe haze episode in January 2013 was 557g/m3 (more recent haze episodes had much lower levels), and the monthly mean was 268g/m3.Footnote 39. Figure 1. The Chinese government also prefers to release information only on PM10 particles and not larger PM particles. Good examples are the Olympic Games in 2008, the APEC (AsiaPacific Economic Cooperation) summit in 2014, and the Second World War 70th-anniversary Military Parade in September 2015. Emissions from motorized vehicles, more specifically the four most dangerous pollutants, sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and particulate matter (e.g. Zhou, Shengzhen New Yorks annual average was 10 or below the past two years.
