存在于人类环境中的3,4-苯并芘,主要产生于燃料的不完全燃烧及有机物的热解。工业锅炉排烟、石油化工、炼焦、染料、塑料等化学化工工艺过程的排气和废水,都能向环境排放不同量的3,4-苯并芘,造成对空气、水体、土壤及其它生物体的污染。水中的3,4-苯并芘主要来自洗刷大气的雨水、工业排污、生活污水和船舶油污等。目前国内尚缺3,4-苯并芘的排放标准和污染指标,1971年《饮用水国际标准》,推荐了萤蒽、3,4-苯并萤蒽、11,12
The 3,4-benzopyrene present in the human environment mainly results from incomplete combustion of fuels and pyrolysis of organic matter. Industrial boiler exhaust, petrochemicals, coking, dyes, plastics and other chemical and chemical processes of exhaust and wastewater, can release different amounts of 3,4-benzopyrene to the environment, resulting in air, water, soil and other organisms Body pollution. 3,4-benzopyrene in water mainly comes from the washing of the atmosphere of rainwater, industrial sewage, sewage and marine oil and so on. At present, 3,4-benzopyrene emission standards and pollution indicators are still lacking in China. The International Standard for Drinking-water in 1971 recommended that anthracene, 3,4-benzofluoranthene, 11,12
