磺胺类抗生素在土壤-植物系统中的迁移特征
Transport processes of sulfonamide antibiotics in soil-plant system
摘要
Abstract
Chinese cabbage,black soil and brown soil were selected to investigate the transfer characteristics of sulfadiazine (SDZ) and sulfamethazine (SMT) and the influence factors in soilplant system using leaching and pot experiments.The results showed that SDZ had higher transfer ability than SMT in soil.The transfer ability of SDZ and SMT decreased with the increase of soil depth.With prolonged leaching time and increased antibiotic concentration,the transfer ability of SDZ and SMT increased in the same soil layers.The transfer ability of sulfonamides differed with soil type.The transfer ability of SDZ and SMT was higher in brown soil than in black soil.The absorption and transfer of the sulfonamides in plants was impacted by their transfer ability in soil.Chinese cabbage took up more SDZ rather than SMT,and the sulfonamides were mainly detected in the stem and leaf of Chinese cabbage.With the increase of sulfonamide concentration,the residue concentration of sulfonamides in Chinese cabbage was increased.The concentrations of SDZ and SMT in Chinese cabbage were higher in brown than in black soil.关键词
