In India, majority of the population is vegetarian, therefore the consumption and demand of vegetables is higher. To enhance the production of vegetables, pesticides are used at higher level. Therefore the population of India is at increased risk to get exposed to higher levels of pesticides. Exposure of pesticide residues at higher level has been found to affect the human health greatly. Present study was aimed to analyze the level of different pesticide residues in two vegetables namely Palak and Radish collected during winter and summer seasons of year 2016, 2017, 2018 and 2019. Overall results showed that the level of Lindane and Chlorpyriphos pesticide residues were higher as compared to FSSAI specification values (2.0 and 0.2) in majority of the vegetable samples irrespective of type, location, season and year. All the vegetable samples containing pesticide residues of Lindane and Chlorpyriphos were treated with different concentrations of aqueous solution of Ozone in order to reduce the pesticide load. We found that the 3 ppm aqueous solution of Ozone reduced the level of both Lindane and Chlorpyriphos in all vegetable samples. These findings reflected higher levels of pesticides in vegetables and present that 3 ppm ozonation can be implemented on vegetables to reduce the pesticide load at personal as well as at organizational level in order to enhance their safety for use in hospitality sectors, as well as for the consumption of native population.
