Soil pH is positively related to the size of the bioavailability of neonicotinoid pesticides, while soil organic matter content and soil aging time are negatively related to the size of the bioavailability of neonicotinoid pesticides.īarraclough, D., Kearney, T., & Croxford, A. By studying the bioavailability of neonicotinoid pesticides, it was found that the bioavailability of the four neonicotinoid pesticides was always: thiamethoxam > acetamiprid > imidacloprid > clothianidin, which may be related to their structural properties. ![]() The results showed that the detection rates and residue levels of neonicotinoid pesticides varied in different regions of Shaanxi. An analytical method applied to assess the bioavailability of neonicotinoid pesticides was established, the bioavailability of different types of neonicotinoid pesticides and related factors affecting their bioavailability were determined, and the changes in the bioavailability of neonicotinoid pesticides in actual and simulated soils were explored. In the study, 115 soil samples collected from different areas from northern, central, and southern Shaanxi were used to determine the residues of four neonicotinoid pesticides: imidacloprid, acetamiprid, clothianidin, and thiamethoxam. In addition, assessing the total residue concentrations would overestimate the actual hazard of neonicotinoid pesticides, so it is essential to study the bioavailability of neonicotinoid pesticides. The rapid development of agriculture has led to an increase in the use of pesticides, which has resulted in a serious pesticide pollution problem. Shaanxi is an important agricultural province in China.
