The distribution characteristics of PAHs in these tissues and organs were analyzed to determine their health risks to humans. The results showed that the residual levels of wet weight and lipid-normalized weight σ.这些鱼的各种组织中的PAHS从0.51 ng·g^-1到28.78 ng·g^-1从93.62 ng·g^-1到8203.43 ng·g^-1， 分别。湿重含量 σ.肝脏和肌肉在大脑和肌肉中相对较高。但差异并不重要。并且脂质归一化的重量PAHs的差异是显着的，其在Bighead鲤鱼中被发现显着最高，伴随着Crucian Carp，以及草鲤鱼和鲤鱼中最低的。内容 σ.PAHS在肝脏中最高，大脑中最低。在具有较高脂质含量的组织中，发现了较高的残留水平的PAH。来自残留的人类的致癌风险 σ.在各种鱼类组织中的PAHS远远低于10^-5。SN - 2356-6140 UR - https://doi.org/10.1100/2012/156378 Do - 10.1100 / 2012/156378 JF - 科学世界期刊PB - 科学世界杂志KW - ER -
