磺胺类抗生素与盐渍化联合胁迫对蔬菜种子发芽的生态毒性效应

The Ecological Toxic Effects of Combination of Sulfonamides and Salinization on the Germination of Vegetable Seeds

摘要: 磺胺类抗生素的滥用导致其对土壤与水体环境造成了严重污染，而土壤盐渍化是目前人类面临的一种主要环境风险。本论文选择使用广泛的磺胺甲恶唑、磺胺甲基嘧啶两种抗生素与氯化钠为研究对象，采用单一、二元与三元联合的方式对不同蔬菜种子的根长、芽长进行监测。结果显示：单一处理组对小白菜生长的抑制作用较强，联合组并未出现明显抑制效应，甚至促进了小白菜生长；各处理组茼蒿的根长均被抑制，而芽长变化不明显；各处理组红丁萝卜的根生长几乎均被促进，联合组的芽长生长也均被促进，而单一组芽长生长被抑制。

Abstract: The abuse of sulfonamides has caused serious pollution to the soil and water environment, and soil salinization is currently a major environmental risk faced by humans. Two widely used antibiotics, sulfamethoxazole and sulfamerazine, and sodium chloride, were selected as the research objects. A single, binary, and ternary combination method was used to monitor the root and shoot lengths of different vegetable seeds. The results showed that the single treatment group had a strong inhibitory effect on the growth of Chinese cabbage, while the combined group did not have a signifi-cant inhibitory effect, even promoting the growth of Chinese cabbage. The root length of Chrysan-themum coronarium in each treatment group was inhibited, but the change of shoot length was not significant. The root growth of red radish was almost all promoted in each treatment group, and the shoot length growth of the combined group was also promoted, while the shoot length growth of the single group was inhibited.
