| Abstract: |
| Residues of organophosphorus pesticides（OPs） in soils from Fuzhou vegetable fields were investigated using GC-FPD. The measured values of Ops were compared against the standard values deduced by SES to assess the risk of OP residues in soils. The results showed that 14（63.64%） out of 22 tested OPs were not detected. The levels and types of OPs were different among soils from different areas. The detectable percentages and residues of phoxime, parathion and chlorpyrifos were 30.23%, 23.26% and 11.63%, and 0.816, 0.090 and 0.181 mg·kg-1, respectively. OPs had different risks to different vegetable varieties. However, the present results show that pollution and health risks of OPs might be still low in vegetable soils in Fuzhou, China. |
