有機磷農藥(organophosphorus pesticide)是一類含有磷元素的合成化合物,主要通過抑制生物體内乙酰膽堿酯酶的活性,破壞神經信號傳遞,從而實現對害蟲的殺滅作用。這類農藥自20世紀中期開始廣泛用于農業、衛生和家庭害蟲防治,具有高效、廣譜、易降解的特點。
作用機制與化學特性
有機磷農藥的核心結構包含磷酸酯或硫代磷酸酯基團,其分子中的磷原子與酯鍵結合。當害蟲接觸或攝入後,化合物會與神經突觸中的乙酰膽堿酯酶發生不可逆結合,導緻乙酰膽堿大量積累,引發神經持續興奮,最終使害蟲癱瘓死亡。例如,世界衛生組織(WHO)在《農藥風險評估指南》中指出,此類農藥的神經毒性對人類和非靶标生物同樣存在潛在風險(來源:WHO官網農藥專題頁)。
應用領域與代表性品種
農業上主要用于防治鱗翅目、鞘翅目等害蟲,常見品種包括馬拉硫磷(malathion)、敵敵畏(dichlorvos)和對硫磷(parathion)。根據中國農業農村部《農藥管理條例》,部分高毒有機磷品種(如甲胺磷)已因環境殘留問題被禁用,但低毒品種仍用于棉花、水稻等作物的蟲害管理(來源:中國農業農村部公告2023年修訂版)。
安全風險與管控措施
美國環保署(EPA)研究表明,有機磷農藥可通過皮膚接觸、呼吸或食物鍊進入人體,急性中毒症狀包括瞳孔收縮、肌肉震顫和呼吸困難。長期低劑量暴露可能影響兒童神經發育。目前全球推行替代策略,如推廣生物農藥和精準施藥技術,以降低健康及生态風險(來源:EPA農藥注冊數據庫)。
organophosphorus pesticide 指含有有機磷化合物(organophosphorus)的農藥,主要用于防治農業害蟲,但過量接觸可能對人體和生态環境造成危害。以下是詳細解釋:
有機磷農藥通過抑制昆蟲或哺乳動物體内的乙酰膽堿酯酶(AChE)活性,導緻神經遞質乙酰膽堿(ACh)無法分解,引發神經持續興奮,最終使目标生物癱瘓或死亡。
根據大鼠半數緻死量(LD50),可分為:
