The 2011 Jiangsu Environmental Conditions Bulletin released by Jiangsu provincial government on June 4 shows the environment in the province is generally improving but some indicators are severe.
The air quality in all the 12 provincially administered cities except Yancheng met the standards and days with clean air in the province increased last year.
The incidence of acid rain lowered in the province as a whole, and Suzhou was the city with the highest frequency of acid rain.
It was getting “noisier” in Suzhou, Changzhou, Wuxi, Huai’an and Yangzhou due to the surge of the number of vehicles on the road.
The province’s surface water environment was slightly polluted, but the sources of drinking water were generally safe. Large-scale blue-green algae outbreaks decreased and the water quality in Yangtze River and Huaihe River deltas was relatively good.
But the surveys on waters of Yangtze River, Beijing-Hangzhou Grand Canal and Taihu Lake show the variety of benthic animals decreased, indicating the urgency in the protection of biodiversity.
