摘要
以中原油田油泥堆放场的油泥样品和沿下风向从距离油泥10、20、50、100、200、500m地点采集的土壤样品为研究对象,通过高效液相色谱法对样品中多环芳烃(PAHs)进行测定。结果显示,油泥样品中PAHs主要来自于石油源,土壤样品按照PAHs来源的不同分为石油源土壤样品和混合源土壤样品。3个不同厂区油泥中PAHs的含量从高到低顺序为:采油三厂文明污泥堆放场(3W)>采油三厂马寨污泥堆放场(3M)>采油四厂文二污泥堆放场(4W)。萘、苊烯、苊、芴和菲是油泥中PAHs的主要污染物。土壤样品中PAHs的含量为434.5～2408.8ng·g-1。根据3个油泥堆放场附近采集到的土壤样品中PAHs的含量可知,3个堆放场附近土壤的受污染程度顺序为:3W>3M>4W。萘、苊、芴、菲和芘是石油源土壤样品中主要污染物,萘和菲是混合源土壤样品中主要污染物。内梅罗常数分级评价结果表明油泥堆放地周围土壤受到严重污染。
The purpose of this study was to determine the degree of contamination with polycyclic aromatic hydrocarbons （PAHs） in samples of oily sludge and soils around oily sludge in Zhongyuan Oil Field. The contents of PAHs in samples were determined with HPLC. According to these data and the ratio of Fla/Pyr, PAHs in oily sludge samples were mainly from petrogenic sources, and the soil samples were divided into petrogenic soil samples and both petrogenic and pyrogenic soil samples by the source of PAHs. The contents of PAHs in three oily sludges plants from high to low was the third Wenming plant of the oily sludge （3W）〉the third Mazhai plant of the oily sludge （3M）〉the fourth Wener plant of the oily sludge （4W）, and naphthalene, acenaphthylene, acenaphthene, fluorine and phenanthrene were major pollutants of PAHs in oily sludge. The contents of PAHs in soil samples around oily sludges varied widely from 434.5 to 2 408.8 ng .g^-1. Naphthalene, acenaphthene, fluorine, phenanthrene and pyrene were major pollutants of PAHs in petrogenic soil samples, and the two predominant PAHs in both petrogenic and pyrogenic soil samples were naphthalene and phenanthrene. Based on Nemero index P, the result of classification evaluation showed that soils around oily sludge were heavily polluted.
