Method validation for simultaneous determination of four neonicotinoids in vegetables by liquid chromatography
Pesticides are widely employed to boost the production of vegetable crops, but their indiscriminate application leaves residue in the crops for long, even after harvesting. Among pesticides, neonicotinoids are...
