Abstract
Human health is the biggest issue with consumption of contaminated vegetables and water. This study aimed to quantify heavy metals in soil, irrigation water, and vegetables in five urban and peri-urban area of Delhi. Under this study, vegetable crops, i.e. spinach, tomato, carrot, potato, onion and mustard were selected and soil, water and vegetable samples were analyzed for five toxic heavy metals, i.e. As, Cd, Cr, Hg, and Pb. Result showed that in irrigation water samples, Cd crossed the WHO/FAO permissible limit at Mehrauli and Najafgarh, while in all vegetable samples Cd content was detected more than permissible limit except for spinach. At all the sites, transfer factor and hazard risk index were observed higher in spinach and okra. The target hazard quotient were higher in spinach (1.184) and correlated with higher As content. Findings revealed that contaminated vegetables consumption needs to be continuously monitored to avoid adverse health impacts.
期刊介绍:
The Journal of Food Safety emphasizes mechanistic studies involving inhibition, injury, and metabolism of food poisoning microorganisms, as well as the regulation of growth and toxin production in both model systems and complex food substrates. It also focuses on pathogens which cause food-borne illness, helping readers understand the factors affecting the initial detection of parasites, their development, transmission, and methods of control and destruction.
