为了摸清湖北省稻虾综合养殖模式下小龙虾农药残留情况，调查了湖北省稻虾综合养殖区19种农药的残留水平，并根据残留结果分析小龙虾农药来源，对稻田小龙虾的生态风险和膳食风险进行了评估。结果显示：在选取的22个稻虾养殖采样点中，水体中共检出3种农药，分别是β-六六六，δ-六六六和异狄氏剂，其中7个采样点为生态高风险，但多是由早期环境残留所致。小龙虾样品中共检出4种农药，其来源与水稻施药有关，其次与小龙虾投入品饲料也有一定的关系。根据小龙虾膳食风险值排序，依次为六氯苯>HCHs>滴滴涕s>二甲戊灵，膳食摄入风险在0.002%~0.206%，因此调查的湖北省稻田养殖中小龙虾农药残留水平在安全范围内，但仍要持续关注农药的多途径暴露和长期暴露对小龙虾的潜在膳食风险。
The residues of 19 pesticides in integrated rice and Procambarus clarkii breeding environments in Hubei Province were investigated， and the ecological risk and dietary risks associated with P. clarkii in paddy fields were assessed. The results showed that three pesticides， β-666， δ-666 and endrin， were detected in the water samples from 22 sites of rice and P. clarkii farming， but most of these residues were attributed to earlier environmental residues. Four types of pesticides were detected in P. clarkii samples， with one source linked to pesticide application on rice， and another related to the feed of P. clarkii. The order of dietary risk values for P. clarkii was hexachlorobenzene > HCHS > DDTs > pendimethalin， with the dietary intake risks ranging from 0.002% to 0.206%. Therefore， the levels of pesticide residues in the rice and P. clarkii breeding environments in Hubei Province are within a safe range， but the potential dietary risks associated with multi-route and long-term pesticide exposure to crawfish warrant ongoing attention.
