Benzpyrenes appear to be common and fairly abundant constituents of soils. Both the carcinogenic 3,4-benzpyrene and its inactive 1,2-isomer have been detected spectroscopically in extracts of soils from rural areas of the eastern United States.
苯并芘似乎是土壤中常见且相当丰富的成分。致癌的 3,4-苯并芘及其非活性的 1,2-异构体都已在从美国东部农村地区土壤的提取物中通过光谱检测到。
