摘要：

新型殺菌劑三氟咪啶酰胺在全球范圍內(nèi)得到了廣泛應(yīng)用，但其在環(huán)境中的穩(wěn)定性和生物毒性令人擔憂。本研究采用實驗室模擬環(huán)境條件下的方法，探討三氟咪啶酰胺在不同環(huán)境條件下的化學變化和相關(guān)轉(zhuǎn)化產(chǎn)物的生物毒性，揭示其環(huán)境行為和生態(tài)風險。研究結(jié)果表明，三氟咪啶酰胺在水、土壤和植物中都存在著不同程度的降解和轉(zhuǎn)化，主要產(chǎn)物有二咪靈、苯甲酸、苯甲醛等多種有機污染物，其中二咪靈是主要的降解產(chǎn)物。通過多種實驗技術(shù)和毒性測試，我們發(fā)現(xiàn)三氟咪啶酰胺和其降解產(chǎn)物對多種生物和環(huán)境因子都具有一定的毒性，包括細胞毒性、致突變性、生理毒性、刺激性等效應(yīng)。因此，必須采取有效的防控措施控制其在環(huán)境中的擴散。
