摘要

Tropospheric O3 is an important pollutant harmful to human health and ecosystem productivity [1,2].It plays a major role in oxidation processes determining the oxidizing capacity of the troposphere and is also an important greenhouse gas contributing to global warming [3],Ground-level O3 pollution is formed by complex photochemical reactions involving anthropogenic and biogenic emitted volatile organic compounds (VOCs) and nitrogen oxides (NOx).Severe O3 pollution episodes have been reported frequently in eastern China,especially in the Yangtze River Delta [4,5].
