[Effects of Sulfamethazine in Soil on Rice Growth].

For the sake of investigating the effects of residual antibiotics in soil on plant growth, sulfamethazine, which is commonly detected in soil, was selected in this project. In general, the growth index of rice at the seedling and mature stages, physiological/biochemical characteristics of roots and leaves, antibiotic residues, enrichment factors, and transport coefficients in various rice organs were respectively tested and analyzed to evaluate the ecological effects of sulfamethazine residues on rice. The results revealed that the inhibitory effect of sulfamethazine on plant height and biomass was maintained during the whole growth cycle.
