Evaluation of the toxicity and risk to plant from perfluorooctane sulfonate

摘要：

The toxicity of perfluorooctane sulfonate (PFOS) to higher plants (Brassica chinensis, Lactuca sativa, Medicago sativa and Raphanus sativus) was investigated. With the concentration of up to 400 mg L-1, PFOS had almost no effect on the seed germination, but affected the root elongation of the four plant species. Based on EC10, EC50 and NOECs, the 96 h root elongation sensitivity of the four plants to PFOS was in the order of Brassica chinensis > Lactuca sativa > Medicago sativa > Raphanus sativus. The influence of soil properties on the bioavailability and toxicity of PFOS to Brassica chinensis root elongation was also studied. The results showed that soil properties could influence the expression of PFOS toxicity. EC50 values for PFOS ranged from 95 to >200 mg kg-1.
