Determination and dietary risk assessment of 284 pesticide residues in local fruit cultivars in Shanghai, China

Abstract The presence of pesticide residues has become one of the main risk factors affecting the safety and quality of agro-food. In this study, a multi-residue method for the analysis of 284 pesticides in five local fruit cultivars in Shanghai was developed based on ultrahigh-performance liquid ch...
