【摘要】 本文报道山西省工业区与非工业区农作物中Ｂａｐ的污染状况。非工业区粮食样品１５２份，含量在０．５ｐｐｂ以下的占样品总数的８６．２％；工业区粮食样品１５８份，含量在０．５ｐｐｂ以下的只占总数的２４％，≥０．５ｐｐｂ的占７６％，其中＞２．５ｐｐｂ的占４８％。认为空气污染是粮食中ＢａＰ污染的主要来源，土壤被污染，尘土飞扬也是另一不可忽视的因素。更多还原

【Abstract】 The BaP contamination in crops in industrial and nonindustrial zones was investigated.The results showed that the content less than 0. 5 ppb in 152 crops’samples constituted the 87.5% of total samples in non-industrial zone. In industrial zone,the similar content in 158 crops′samples constituted only 24%; the content more than 0.5ppb 76%,in which content more than 2. 5 ppb constituted 18%. We drew the conclusion that air pollution might was the primary pollution source of BaP in crops.更多还原
