  • 摘要: 甲酰氨基嘧磺隆是一种新型磺酰脲类除草剂,其在环境中的归趋备受关注.采用室内模拟试验方法,研究了甲酰氨基嘧磺隆在不同土壤中的降解性、水解和光解特性.结果表明,甲酰氨基嘧磺隆在光照强度4000 lx,紫外强度25 μW·cm-2的人工光源氙灯条件下,甲酰氨基嘧磺隆的光解半衰期为1.72 h,易光解.25℃时,pH4、pH7和pH9条件下水解半衰期分别为4.17、91.2、97.6 d,50℃时的水解半衰期分别为<1 d、4.75 d和14.5 d,温度和pH值对水解速率具有较大影响.甲酰氨基嘧磺隆在江西红壤、太湖水稻土和东北黑土中的降解半衰期分别为10.8、16.6、31.5 d,该药在酸性土壤中降解较快,影响其在土壤中降解速率的主要因素为土壤pH值.
    Abstract: Foramsulfuron is a new type of sulfonylurea compounds, and its environmental behavior has caused increased concern. Hydrolysis, photolysis and biodegradation are 3 important transformation pathways of herbicides in environment. In this study, the photolysis, hydrolysis and biodegradation of foramsulfuron were investigated through simulation test in laboratory. The results showed that foramsulfuron was rapidly degraded under UV radiation, and the photolysis half-life was 1.72 h at the energy density of 25 μW·cm-2 using Xe lamp. However, the hydrolysis of foramsulfuron was rather slow. The half-lifes were 4.17, 91.2 and 97.6 d at pH 4.0, 7.0 and 9.0, respectively at 25℃. But the hydrolysis half-life changed to <1 d, 4.75 and 14.5 d at pH 4.0, 7.0 and 9.0 respectively at 50℃. It was observed that temperature and pH were the key factors affecting the kinetics of hydrolysis. The soil degradation half-lifes of foramsulfuron were 10.8, 16.6 and 31.5 d respectively in Jiangxi red soil, Taihu paddy soil and Northeast black soil. The results showed that soil pH was the major factor that affected the degradation rate of Foramsulfuron in soil.
