Monitoring of pesticide residues in vegetarian diet

Abstract

Samples (28) of complete vegetarian diet consumed from morning till night i.e. tea, milk, breakfast, lunch, snacks, dinner, sweet dish etc. were collected from homes, hostels and hotels periodically from Hisar and analysed for detecting the residues of organochlorine, synthetic pyrethriod, organophosphate and carbamate insecticides. The estimation was carried out by using multi-residue analytical technique employing gas chromatograph (GC)-electron capture detector and GC-nitrogen phosphorous detector systems equipped with capillary columns. The whole diet sample was macerated in a mixer grinder and a representative sample in duplicate was analyzed for residues keeping the average daily diet of an adult to be 1,300 g. On comparing the data, it was found that actual daily intake (microgram/person/day) of lindane in two and endosulfan in four samples exceeded the acceptable daily intake. Residues of other pesticides in all the diet samples were lower than the acceptable daily intake (ADI) of the respective pesticides. The study concluded that although all the diet samples were found contaminated with one or the other pesticide, the actual daily intake of only a few pesticides was higher than their respective ADI. More extensive study covering other localities of Haryana has been suggested to know the overall scenario of contamination of vegetarian diet.

Monitoring of pesticide residues in market basket samples of vegetable from Lucknow City, India: QuEChERS method

“…Currently pesticides (OPs, SPs, and H) enjoy wide use in the world as an alternative pest control replaying persistent organochlorines (Lyton et al 1996;Subhani et al 2001;Toan et al 2007). Because of wide spread use of pesticides, the presence of their toxic residues (Torres 2004) have been reported in various environmental component/commodities (Cox et al 1999;Kumari et al 2002Kumari et al , 2003aKumari et al , b, 2004Kumari et al , 2005Kumari et al , 2006Kumari and Kathpal 2008;Srivastava et al 2000Srivastava et al , 2001Srivastava et al , 2006Wang et al 2008), These pesticide residues find their way into the human body through food, water, and environment. Thus, analysis of pesticide residues in food and other environmental commodities like soil, water, fruits, vegetables, and total diet have become essential requirement for consumers, producers, and foodquality control authorities.…”

Monitoring and Risk Assessment of Pesticide Residues in Some locally produced Vegetables and Fruits

“…No violation of acetamiprid and imidacloprid was detected. The highest violated concentration in tomato samples was in Dakahlia governorate for chlorpyrifos and propargite with values of 0.38 and 0.031 mg kg-1, respectively, Table (2) and Figure (2) show that out of 50 samples of potato tubers, no pesticide residues were detected in 20 samples (40%), while, the remaining 30 samples Despite the high frequency of chlorpropham (21 times) with the concentration of 3 mg kg-1, no violation was present. Whereas, profenofos which was found only 3 times with concentration of 0.51 mg kg-1, had a violation of 10%.…”

“…The application of pesticides has led to an increase in agricultural production worldwide, but some pesticide residues may have potentially adverse impacts on the environment and human health [1]. Residues resulting from the inappropriate use of pesticides on crops have shown to be a major concern worldwide [2]. Fruits and vegetables are rich sources of vitamins, minerals, and fibres and even have beneficial antioxidative effects.…”

Analysis of Multi-Residue Pesticides in Vegetable Samples Using Solid-Phase Micro-Extraction (SPME) Coupled to Gas Chromatography-Electron-Capture Detector (GC-ECD)

“…Several methodologies have been developed for sample preparation prior to the analysis of pesticides from biological, food or environmental samples [14,15] . SPME was first developed in 1989 by Pawliszyn and coworkers and has been marketed by Supelco since 1993.…”
