Abstract:
Current study was proposed to measure the level of heavy metal residues in Palak vegetable samples collected during the winter and summer seasons of the year 2016, 2017, 2018 and 2019 from different locations of Delhi/NCR. Results showed that the level of overall heavy metal residues was higher as compared to FSSAI specification values in palak samples irrespective of the location of sample collection and season and year of collection. Palak samples contaminated with heavy metal residues were treated with different concentrations of an aqueous solution of acetic acid to reduce the pesticide load. We found that the 10% aqueous solution of acetic acid reduced the level of heavy metals in palak samples. These findings reflected the presence of higher levels of heavy metals in palak samples and present that 10% acetic acid can be implemented on vegetables to reduce the pesticide load at the personal as well as at organizational level to enhance their safety for use in hospitality sectors, as well as for the consumption of the native population.
