摘要： In this study, the environmental fate of thymol, including hydrolysis, aqueous photolysis, soil sorption and soil degradation, was studied under conditions that simulated the tropical agricultural environment. This study was undertaken to supply basic information for evaluating the environmental risks of applying this new botanical pesticide to tropical crop production. The results showed that the hydrolysis of thymol was pH-dependent and accelerated by acidic conditions and high temperatures. However, the hydrolysis rate was far lower than the aqueous photolysis rate, indicating that direct photolysis is an important dissipation pathway for thymol in water. The sorption of thymol by three tropical soils was consistently well described by the Freundlich model, and the sorption coefficients increased in the order sandy soil < loamy soil < clay soil, a characterization that depended on the organic carbon contents of the soil. The soil degradation rate of thymol decreased in the order sandy soil > loamy soil > clay soil, which has a negative correlation with the sorption of thymol in soils. We concluded that the degradation rates of thymol in tropical soil and water are fast: thymol in water is photodegraded (50%) by sunlight within 28h, and the thymol in soils is degraded (50%) within 8.4 d. Therefore, the environmental risk to the surrounding soils and water of thymol application for tropical crop production is low.
