| 中文摘要: |
| 采用气相色谱-火焰光度检测器（GC-FPD），测定福州菜地土壤样品中OPs的残留量，同时采用SES推导公式推算其土壤中的环境标准值与实测值进行比较，从而评价土壤中OPs残留量对蔬菜的种植风险。研究结果表明，22种OPs中，未检出的有14种，占检测OPs种类的63.64%，不同县（市、区）菜地土壤样点中检出OPs的品种数及其检出率和残留量差异较大，辛硫磷、对硫磷和毒死蜱检出率较高，分别为30.23%、23.26%和11.63%，平均残留量为0.816 、0.090、0.181 mg·kg-1，是福州菜地土壤主要污染物。研究还表明，OPs的残留量对不同蔬菜种植风险程度不同，但菜地土壤中OPs污染总体水平和风险水平均较低。 |

| 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. |
