农作物中微囊藻毒素的富集、危害及食用风险研究进展

Bioconcentration,phytotoxicity and health risk of microcystins in crops:research progress

微囊藻毒素(microcystins,MCs)是最受关注的一种蓝藻毒素,其可对肝脏产生伤害,具有急性肝毒性作用,长期摄入可引发肝癌。除水体和水产品外,MCs还可通过其污染的灌溉水富集在农作物中,增加人群的食用风险。本文系统概述了微囊藻毒素在不同农作物中的富集情况及其对农作物的毒性作用,同时评价了农作物可食用部分残留的MCs对人类健康的潜在危害。

Microcystins(MCs),being among the most concerned cyanobacterial toxins and with acute hepatotoxic effects,can induce liver damage and even lead to liver cancer after long-term intake.Addition to existing in contaminated water and aquatic products,MCs can also be accumulated in crops via polluted irrigation water,which could increase the health risk of human.In this paper,we systematically reviewed the enrichment characteristics of MCs in different crops and their toxicities to those crops.The potential health risks from MCs residues in edible parts of crops were also discussed.
