The results show that in the period of crop growth, hourly mean ozone concentration, ozone concentration averaged in seven hours of daytime and accumulated ozone concentration in long period have approached or overpassed the harmful level in environmental and health standard of U. S. A. and Canada.展开更多

The observation sites were set up at three locations on the south slope of Lushan Mountain: TV station (1400 m elev.), Botanical Garden (1100 m elev.) and Guang Yin Qiao (70 m elev.). These sites were within 5—6 km in展开更多
