以小鼠精子形态试验研究了小清河水有机污染物对哺乳类生殖细胞的遗传毒性。结果表明上、下游水样均可导致小鼠精子畸形率的显著增高，说明其中含有可穿越血睾屏障作用于生殖细胞的诱变物质。干扰了正常的生精过程，有可能造成可传递的遗传损伤。
The genotoxicity of organic pollutants from Xiaoqing River to mammalian germ cells was studied using mouse sperm morphology. The results showed that both upstream and downstream water samples can cause sperm deformity in mice significantly increased, indicating that it contains the blood testis barrier can affect the germ cells mutagenized substances. Interfere with the normal process of spermatogenesis, may cause transmissible genetic damage.
