摘　　要：雌酮(E1)、17β-雌二醇(E2)、雌三醇(E3)、17α-炔雌醇(EE2)和双酚A(BPA)等作为畜禽粪污中雌激素活性较强的环境内分泌干扰物,可在农田土壤-作物系统内输运和累积,并对野生物种的生殖发育、遗传代谢,以及农产品的质量和安全构成巨大威胁.目前,国际上关于粪肥源雌激素在农田土壤-作物中污染特征、转运规律及毒理风险的报道仍较少.本文综述了5种代表性粪肥源雌激素在农田生态系统中的污染特征和时空分布规律,归纳了雌激素在农田土壤-作物中的迁移转化、吸收积累和代谢机理,系统地评估了农田生态系统中雌激素生物毒性效应及其风险模型,旨在为规避农田土壤-作物雌激素污染风险、生产绿色农产品和保障人民健康等奠定理论基础.In livestock manure,estrogens such as estrone(E1),17β-estradiol(E2),estriol(E3),17α-ethinylestradiol(EE2),and bisphenol A(BPA),act as a category of representative environmental endocrine disruptors with strong estrogenic activity.These estrogens can be migrated,transported,and accumulated in agroecosystems,which trigger a great threat to the reproductive development and inherited metabolic disorders,as well as the quality safety of agricultural products,thus arousing enormous pollution concerns.At present,there is little information available on the pollution characteristics,transport regularities,and toxicological risks of animal manure derived-estrogens in farmland soil-crop ecosystems.This study overviewed the pollution characteristics and temporal-spatial distribution of the above mentioned 5 kinds of typical manure derived-estrogens in agroecosystems.The uptake,accumulation,and metabolic mechanisms of estrogens in farmland soil-crop ecosystems were also summarized.Subsequently,the biotoxic effects of estrogens and their ecological risk models were systematically evaluated in farmland ecosystems.These findings provide a theoretical foundation for avoiding the estrogen-polluted risks of farmland soil-crop,yielding green agricultural products,and protecting public health.
