磺酰脲类除草剂的应用及检测方法

磺酰脲类除草剂是上世纪80年代美国杜邦公司研发出来的一种除草剂，其具有高效、广谱、低毒、高选择性等优点，因此，一经问世就得到了广泛应用。但是，由其引起的土壤、地下水污染问题而饱受诟病。有些磺酰脲除草剂难以降解，可对环境造成持续的污染，更有甚者，农作物也会因此而造成农残超标。因此，磺酰脲类除草剂在环境、农产品中的残留问题及和检测技术研究进展值得我们关注。

Application and determination of sulfonylurea herbicides

Sulfonylurea herbicide is a kind of herbicide developed by DuPont company in the 1980s. It has the advantages of high efficiency, broad spectrum, low toxicity and high selectivity. Therefore, it has been widely used once it came out. However, the soil and groundwater pollution caused by it has been criticized. Some sulfonylurea herbicides are difficult to degrade, which can cause continuous pollution to the environment. What''s more, crops will also cause excessive agricultural residues. Therefore, the research progress of sulfonylurea herbicide residues in environment, agricultural products and detection technology is worthy of our attention.
