Long-term trends of fine particulate matter and chemical composition in the Pearl River Delta Economic

Xuemei WANG,Weihua CHEN,Duohong CHEN,Zhiyong WU,Qi Fan

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 1,   Pages 53-62 doi: 10.1007/s11783-014-0728-z

Abstract: Understanding the trends in PM levels is essential for formulating clean air plans. This paper analyzes PM data from various published sources for the years 2000 to 2010 in the Pearl River Delta Economic Zone (PRDEZ). The long-term variation in PM mass concentration is analyzed. Results show that PM , organic carbon (OC), elemental carbon (EC), and show a similar trend, increasing before 2005 and then decreasing slightly. The annual average PM concentration ranges from 49.1 μg·m in 2000 to 64.3 μg·m in 2010, with a peak of 84.1 μg·m in 2004. None of these 11 years meets the new National Ambient Air Quality standard (NAAQS) for PM (35 μg·m ). Overall average concentrations of OC, EC, and are 13.0, 6.5, and 11.8 μg·m , respectively. and respectively have concentrations of 1.5 μg·m and 2.9 μg·m in 2000 and 6.4 μg·m and 5.3 μg·m in 2010, with a statistically significant average annual trend of+ 0.2 μg·m ·yr and+ 0.1 μg·m ·yr . In certain geographic regions, OC and EC contribute most of the PM , while in other regions secondary water-soluble ions are more important. In general, OC and are the dominant components of PM , contributing 20.6% and 18.6%, respectively. These results provide, for the first time, a better understanding of the long-term PM characteristics and trends, on a species-by-species basis, in the PRDEZ. The results indicate that PM abatement needs to prioritize secondary species.

Assessing the premature death due to ambient particulate matter in China’s urban areas from 2004 to 2013

Guoxia MA, Jinnan WANG, Fang YU, Xiaomin GUO, Yanshen ZHANG, Chao LI

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 5, doi: 10.1007/s11783-016-0849-7

Abstract: The number of annual premature deaths attributable to China’s air pollution ranged from 350000 to 520000 from 2004 to 2013, while the figure in 2013 reached 9.9% of total deaths in China. In 2004, the life expectancy potential years of life lost was 69.6 and 1.85 years respectively in contrast to 74.4 and 0.67 years respectively in 2013. The number of PYLL attributable to air pollution in the northern regions is found to be larger than that of the southern regions. The Environmental Burden of Disease (EBD) approach for outdoor air pollution has been used to calculate premature deaths and average potential years of life lost attributable to air pollution in China over the past 10 years with differences between the North and the South of the country being analyzed. The results indicate that: (1) Between 2004 and 2013, annual premature deaths attributable to outdoor air pollution in China ranged from 350000 to 520000. In 2013, deaths resulting from air pollution in China represented 9.9% of the country’s total deaths. (2) In 2004, the average life expectancy of the Chinese population and the number of potential years of life lost (PYLL) attributable to air pollution was 69.6 and 1.85 years respectively as compared to 74.4 and 0.67 years respectively in 2013. (3) The number of the PYLL attributable to air pollution in the northern regions of China is found to be larger than that of the southern regions. The PYLL figures of the northern and southern regions in 2004 were 2.3 and 1.8 years, respectively, with a difference of 0.5 years, as compared to 1.4 and 0.7 years respectively with a difference of 0.7 years in 2013.
