| Abstract: |
| To investigate the accumulation characteristics of different antibiotics in Chinese cabbage from different soils, the accumulation of typical antibiotics, including sulfadimidine(SM2), sulfamethoxazole(SMZ), tetracycline(TC), and oxytetracycline(OTC), in Chinese cabbage were evaluated from three soils(yellow clunamon soil, lime concretion black soil, and red soil)through soil pot experiment. The results showed that the concentrations of the four antibiotics in Chinese cabbage from the three soils reached the highest concentrations on the 10th day and then gradually decreased. The concentration of antibiotics in vegetables increased with increasing initial concentrations of antibiotics in soils. When the initial concentration of antibiotics in the soil was 25.0 mg·kg-1, the concentration of antibiotics in Chinese cabbage was significantly higher than at lower initial concentrations. Under the same initial concentration of antibiotics in soil, the concentration of the antibiotics in Chinese cabbage varied greatly under different soil types. Soil pH and organic matter content were important factors affecting the antibiotic accumulation in Chinese cabbage. In the same soil, the accumulation sequence of different antibiotics in vegetable was in the order:SM2 >SMZ>OTC>TC, which was because the adsorption of TCs in the same soil was much higher than that of SAs, and different antibiotics had different physical and chemical properties. Chinese cabbage absorbed antibiotics from soils and the concentration of antibiotics was the highest on the 10th day after transplantation. The accumulation of antibiotics in Chinese cabbage was the highest in acidic soil(red soil), followed by neutral soil(yellow-cinnamon soil), and it was the lowest in alkaline soil(lime concretion black soil). The accumulation ability of Chinese cabbage to SAs was stronger than TCs, and the higher the initial concentration of antibiotics in soil, the higher the concentration of antibiotics in Chinese cabbage. |
