Effect of Different Irrigation Sources on Proximate Composition and Heavy Metals Uptake in Some Selected Vegetables

Abstract

M of agricultural lands especially near urban areas are irrigated by city or municipal waste water due to insufficient availability of fresh water, undemanding accessibility and discarding problems of waste water. Waste water is recognized markedly to add heavy metals into soils (Mapanda et al., 2005; Ahmad et al., 2015; Khan et al., 2016). Heavy metals are injurious to humans and animals due to their solubility in water, non-biodegradable nature and their potential to build up in various body parts. These are even toxic and detrimental to humans at very low concentrations as there is no proper route for their removal from the body.
