摘要:Regarding environmental hygiene, as the pesticides in current use have high solubility in water, pesticides applied to paddy-field soil are detected in river water. Their residual potentials are low and the residual period in river water ranges from two weeks to one month. Regarding food hygiene, a number of pesticides in current use have been detected in vegetables and fruits. The number of cases in which pesticides are detected in vegetables and fruits at above the minimum residue level is very small.
