RESUMO
Objective To review the status of pesticide residues in vegetables and fruits and the progress of risk assessment, and to provide data support for pesticide residue research, residents' dietary exposure risks and safety risk management. Methods Domestic and international literature and research data available are reviewed and analyzed. Results This article mainly reviews the literature on the investigation of current status of pesticide residues in vegetables and fruits. It also discusses several methods and models that have been widely employed in the dietary exposure risk assessment of pesticide residues worldwide. Conclusion Pesticide residues have been frequently reported in vegetables and fruits, mainly including organophosphorus, organochlorine, carbamate and pyrethroid pesticide residues. The relevant risk assessment results indicate that different groups of people, especially those with high exposure, have cumulative dietary exposure risks to pesticides in vegetables and fruits. Although most pesticide residues have been detected at low concentrations in vegetables and fruits, they have potential toxicity risks and require continuous attention.
