稻田养殖克氏原螯虾重金属监测分析

目的]了解扬州地区稻田养殖克氏原螯虾的重金属污染情况。方法]采集了扬州市3个区套养克氏原螯虾稻田的水质、底泥和克氏原螯虾样本,并对其进行了重金属砷、镉和汞的检测和分析。结果]检测显示,所有监测稻田的水质和底泥的重金属砷、镉和汞的检测值都符合无公害水产品养殖环境要求,环境无明显重金属污染;克氏原螯虾的重金属砷、镉和汞的检测值未超过无公害水产品质量安全要求,也未超过我国水产品规定的最大残留标准,且平均检测值都相对较低,对人的健康风险较小。结论]研究可为稻田养殖克氏原螯虾的健康发展及质量保证提供参考。

Monitoring Analysis of Heavy Metals in Rice Paddy Procambarus clarki

Objective] The aim was to study heavy metals in rice paddy Procambarus clarki in Yangzhou region.Method] Collecting water sample of paddy field, sediment and Procambarus clarki from three regions of Yangzhou City, arsenic, cadmium and mercury were detected and analyzed.Result] The results showed that all the monitoring of water quality in rice paddies and sediment of heavy metals arsenic, cad-mium and mercury readings are conform to the requirements of the pollution-free aquatic products breeding environment, the environment has no obvious heavy metal pollution;Procambarus clarki heavy metals arsenic, cadmium and mercury values does not exceed pollution-free aquat-ic products quality and safety, the average detection value is relatively low and has less risk to human health. Conclusion] The study can provide reference for healthy development and quality assurance of rice paddy Procambarus clarki.
