| 为明确梯田稻鱼共作环境中有机氯农药（OCPs）的残留现状及其生态风险，于2017年5月采取红河县哈尼梯田所在区域不同海拔的水样和土样，并通过气相色谱仪检测定量进行OCPs的组成、来源分析和生态风险评价。结果表明，水体中共有12种OCPs被检出，残留总量范围为60.43~4 335.35 ng·L-1，平均值为650.35 ng·L-1；底泥环境中检测到11种OCPs，残留总量范围为6.68~26.36μg·kg-1，平均值为12.29 μg·kg-1。哈尼梯田环境中氯化脂环类OCPs高于氯苯类，主要分布于底泥环境中。从各海拔位点得到的检测结果来看，OCPs的残留并没有随海拔高度而变化。来源分析表明，该地区除历史性残留的OCPs外，存在新的OCPs输入。风险评价最终结果发现，水源汇合处、低海拔和中海拔地区水样中异艾氏剂的残留对水体鱼类存在较大风险；底泥中OCPs的残留风险要高于水中，部分采样位点六六六类、滴滴涕类、硫丹Ⅱ、氯丹和异狄氏剂存在较高的生态风险，而七氯在各个位点的残留均有较大的生态风险。总结得出梯田稻鱼共作环境中，底泥中的OCPs残留较水体需要更多的监控，而OCPs残留中的氯化脂环类需要进一步引起重视。 |

| The rice-fish agriculture model was introduced into the Hani Terraces of Yunnan in order to protect the traditional culture of terraced farming in China and promote the policy of precise poverty alleviation. Due to the accumulation of organochlorine pesticides (OCPs) in both agricultural environments and high altitude areas, the residual status and ecological risks of OCPs in the environment of rice-fish coculture in the terraces need to be clarified. In this study, water samples and soil samples from different altitudes in Hani Terrace area of Honghe County were collected in May 2017. The composition, source analysis, and ecological risk assessment of OCPs were performed after gas chromatograph detection. The results showed that 12 kinds of OCPs were detected in the water body, and the total residual amount ranged from 60.43 ng·L-1 to 4 335.35 ng·L-1 with an average value of 650.35 ng·L-1. Furthermore, 11 kinds of OCPs were detected in sediment, the range was 6.68~26.36 μg·kg-1 with an average value of 12.29 μg·kg-1. The chlorinated alicyclic OCPs in the Hani Terrace fields were higher than the chlorobenzenes and were mainly distributed in the sediment environment. The residual OCPs were not change with altitude according to the detection results obtained at each altitude point. The source analysis indicated that there were new OCPs inputs in the area except for the historical residual OCPs. The final result of the risk assessment found that residues of isodrine in water samples at the confluence of water sources, low altitude and mid-altitude areas presented a greater risk to water fish. The risk of residual OCPs in sediment was higher than that in water. There were high ecological risks in some sampling sites in sediments, including HCHs, DDTs, endosulfan Ⅱ, chlordane and endrin, while the residual heptachlor in each sampling point. The conclusion was that the residues of OCPs in sediment need more monitoring in the rice-fish coculture environment, and the residual chlorinated alicyclics OCPs needed further attention. This study provides guidance for the protection of terrace ecological environment by these theoretical data, which is more conducive to the precise promotion of the next step. |
