土壤中磺胺类兽药残留的生态效应及转归

Ecological Effects and Fate of Veterinary Sulfonamide Antibiotics Residue in Soil

磺胺类药物(Sulfonamides,SAs)是指具有对氨基苯磺酰胺结构的一类药物。磺胺类抗生素是人工合成的高效广谱抗菌药,广泛应用于农业、水产、畜牧养殖和人类疾病治疗中,其在环境中的大量残留带来了潜在的环境风险。此文综述了磺胺类抗生素兽药对土壤环境的生态毒性、土壤中磺胺类兽药残留的检测,以及在土壤中的吸附转移和降解,并对今后的研究方向进行了展望。

Sulfonamides,a structurally related group of antibiotics containing a similar 4-aminobenzene sulfonamide backbone.Sulfonamides are synthetic antimicrobial agents which are active against a broad spectrum of pathogenic Gram-negative and Gram-positive bacteria,are extensively used in agriculture,aquaculture,animal husbandry,and also as human medicines.Its residues in environment bring to a potential hazard.The eco-toxicity of veterinary sulfonamide antibiotics residue on soil environment,determination,transport,sorption and degradation in soil are summarized in this paper,and the possible future study is also prospected.
