化工行业突发大气污染事故统计与趋势分析
Statistics and Trend Analysis of Sudden Atmospheric Pollution Accidents in Chemical Industry
摘要
Abstract
Sudden atmospheric pollution cases in domestic chemical industry(1972-2011)were collected. Non-transport sourced cases were analyzed from three perspectives:occurring links,pollutants and the time of occurrence. The causes,the variation tendency of accidents' amount and grade were discussed. The results showed that storage and production were two accident-prone links;explosion and leakage were the main types of accidents;most cases were in the second and third quar-ters of the year;and chlorine,hydrogen sulfide,carbon monoxide,ammonia,benzene and BTEX caused most leakageand also the most destructive accidents.Within the statistical range,the annual death of per accident rises at first and goes down later. As time progresses,the accident range pyramid changes from the one with a small bottom and a big middle to the one with a big bottom and a small top. According to the above analysis results,some preventingmeasures and suggestions were proposed for possible producers.关键词
