To determine the behavior of oxytetracycline (OTC) and heavy metals in soil, this study assessed the pollutant-induced avoidance behavior of earthworms (E. fetida) exposed to zinc (Zn), lead (Pb), and OTC in soil. The results showed a clear avoidance response within 48h of exposure to the highest concentrations of pollutants. Moreover, E. fetida was shown to be more sensitive to Zn than to Pb and OTC. Compared with OTC alone, the net response of earthworms increased in the OTC-Zn and OTC-Pb combined treatments, indicating a synergistic effect. Moreover, the net response (NR) of the earthworms was higher for OTC-Zn than it was for OTC-Pb, possibly reflecting the differences in essential characteristics of Zn and Pb.
为了确定土霉素(OTC)和重金属在土壤中的行为,本研究评估了暴露于土壤中锌(Zn)、铅(Pb)和OTC的蚯蚓(赤子爱胜蚓)的污染物诱导回避行为。结果表明,在暴露于最高浓度污染物的48小时内出现了明显的回避反应。此外,结果显示赤子爱胜蚓对Zn比对Pb和OTC更敏感。与单独使用OTC相比,在OTC-Zn和OTC-Pb联合处理中蚯蚓的净反应增加,表明存在协同效应。此外,蚯蚓对OTC-Zn的净反应(NR)高于对OTC-Pb的净反应,这可能反映了Zn和Pb基本特性的差异。
