摘要
现今农作物中大量的农药使用导致环境中的有害化合物的累积,证明了其对人类动物以及土壤微生物的威胁。 在土壤、水和食物中这些农药残留已有报告。多菌灵和磺酰磺隆是使用最广泛的农药用于治疗作物的真菌疾病和杂草。多菌灵是一种苯并咪唑杀菌剂可损害肝脏以及内分泌系统,且被怀疑具有诱变和致瘤的效果。类似磺酰磺隆,一种磺酰脲类的除草剂的发展可能导致杂草产生耐药性并遗留影响到下一个作物栽培。这些杀虫剂具有长的半衰期,因此能长期存留在环境中,在不久的将来可能会导致有害的后果。除了化学和光降解型农药,微生物降解现已演变为更有效、安全的方式用以消除这些来自环境的有害化合物。然而只有有限的报告是关于化合物微生物降解的。当前综述强调的主要是多菌灵和磺酰磺隆的化学性质、检测残留、有害影响和降解研究见解。 此外,使用高效的微生物修复农药环境也在被讨论。

摘要: A large amount of pesticides are being used now-a-days in crop protection which has resulted in buildup of such harmful compounds in the environment, proving a menace to humans, animal life as well as to soil microbes. Residues of these pesticides have been reported in soil, water and foods. Carbendazim and sulfosulfuron are among the most widely used pesticides for treating fungal diseases and unwanted herbs in crops respectively. Carbendazim is a benzimidazole fungicide which can harm liver as well as the endocrine system and is suspected to have mutagenic and tumorigenic effects. On similar lines sulfosulfuron, a sulfonylurea herbicide may result in the development of resistant herbs displaying its carry-over effects to the next crop cultivated. These pesticides possess large half-lives and thus remain persistent in the environment which may lead to harmful consequences in the near future. Besides chemical and photo-catalytic degradation of pesticides, microbial degradation has now been evolved as a much effective and safer way to eradicate these harmful compounds from the environment. However a limited literature is available on the microbial degradation of such compounds. The present review emphasizes mainly upon the chemical properties of Carbendazim and Sulfosulfuron, detection of their residues, harmful effects and insights into their degradation studies. Further, the use of efficient microbes for remediation of pesticides from the environment has been discussed.
