报告内容简介:

World Health Organization (WHO) reported that some 3 million deaths a year are linked to exposure to outdoor air pollution including PM2.5. Nearly 90% of air-pollution-related deaths occur in low- and middle-income countries, with nearly 2 out of 3 occurring in WHO’s South-East Asia and Western Pacific regions. I collected airborne particulate matters (PM) at four cities in Japan from the late 1990s and five or more major cities in China, Korea and Russia from 2001, and determined polycyclic aromatic hydrocarbons (PAHs) and eleven nitropolycyclic aromatic hydrocarbons (NPAHs) by HPLC with fluorescence and chemiluminescence detections, respectively. Annual concentrations of PAHs and NPAHs were significantly different in the four countries with seasonal difference. Concentrations of PAHs and NPAHs in Japanese cities significantly decreased but did not decrease in several Chinese and Russian cities. Concentrations of PAHs and NPAHs were higher in the Northern China than those in the Southern China. The dramatic change in atmospheric concentrations of PAHs and NPAHs suggests the rapid and large change of PM2.5 pollution levels as well as sources in East Asia. Considering the adverse health effects of PM2.5, continuous monitoring of atmospheric PAHs and NPAHs is necessary in this area.
