Abstract:
The statistics and analysis were made on 3 203 environmental emergencies and their environmental pollution emergencies in China from 2011 to 2017 from six aspects, including the development trend, spatial distribution, receptor types, pollution factors, pollution causes and industrial characteristics. The results showed that from 2011 to 2017, the number of environmental emergencies was on the whole decreasing, and the general environmental events were the main events, accounting for 95.50%. East China was the main site of environmental emergencies, accounting for 46.99%. Shanghai had the largest cumulative number of environmental emergencies (761), followed by Shaanxi Province (360) and Jiangsu Province (347). The water was the main pollution acceptor of environmental pollution emergency events, accounting for 85.59%. The wastewater from industrial enterprises was the main pollution factor causing environmental pollution emergency events, accounting for 26.73%. Human factors were the main factors causing environmental pollution emergency events, among which the contribution rate of illegal pollutant discharge by enterprises reached 36.56%. The production and supply of water power and the manufacturing of chemical raw materials and chemicals were the industries with frequent environmental pollution emergency events. The research showed that it was necessary to improve the risk management system of environmental emergencies, strengthen the diversified supervision of industrial wastewater discharge, and reinforce the management of industries with high accident rate to effectively prevent and control environment pollution emergency events.
