Abstract :

India finds it difficult to suffice the needs of ever growing population and use of pesticides in vegetables has increased several folds in the last several years. In tropical conditions, fruits and vegetables are grown throughout the year and cauliflower is highly nutritious and fious, helps in scavenging free radicals from the body to prevent incurable diseases. Vegetable samples of cauliflower collected from Bangalore urban district and subjected to gas chromatography equipped with ECD and FTD. Recovery studies performed at fortification levels of 1.0, 0.5 and 0.01mg/kg and the average recovery rates ranged from 77.3 to 94.7%. Variation in acephate, chlorpyriphos, dichlorvos, monocrotophos, phorate, cyfluthrin–β, cyhalothrin–λ, cypermethrin, deltamethrin and fenvalerate residues in cauliflower samples is recorded. It is found that 12.5% of samples from Bangalore urban were having phorate residue value above the MRL of 0.05mg/kg. Pesticides though present in cauliflower sample in Bangalore urban district and not exceeded the MRL
