Environmental fate of chlorantraniliprole residues on cauliflower using QuEChERS technique

Environmental Monitoring and Assessment, 2012
Chlorantraniliprole, an anthranilic diamide insecticide with novel mode of action is found effective against several lepidopteran as well as coleopteran, dipteran, and hemipteran pests. The present studies were carried out to study the dissipation pattern of chlorantraniliprole on cauliflower and to suggest suitable waiting period for the safety of ...

Detection of pesticides in crops: A modified QuEChERS approach

Food Control, 2012
Abstract The general term “pesticide” includes a large number of substances that belong to many different chemical classes. Pesticides are applied to crops at various stages of cultivation to provide protection against weeds and pests, and during post-harvest storage to preserve quality.

Making the case for QuEChERS-gas chromatography of drugs

TrAC Trends in Analytical Chemistry, 2016
Abstract Over the past decade, QuEChERS (quick, easy, cheap, effective, rugged, and safe) has evolved into one of the most widely used extraction techniques for residue analysis. Since its inception, this method is considered particularly adept in the extraction of polar and basic compounds, and hence the majority of methods developed using QuEChERS ...
