Abstract

在北黄海中部泥质区采集柱状沉积物样品,对多环芳烃(PAHs)和黑碳(BC)的含量和来源进行研究。结果表明:(1)PAHs的含量变化范围为207~611ng/g;BC的含量变化范围为0.560~1.32mg/g;(2)对比低分子量(LMW)和高分子量(HMW)PAHs含量的历史变化趋势,发现1980s之前的PAHs主要来自于生物质的低温燃烧,之后主要来自于化石燃料的高温热解;(3)1920s之前,PAHs与BC含量基本保持稳定且处于较低值。1920s-1980s,PAHs含量受工业化和煤炭发展的影响较大,开始出现增长趋势。1980-1990s,由于能源消耗量的大幅度增加,导致PAHs和BC的含量..
