Heavy metal (Cu, Zn, Cd and Pb) contamination of vegetables in urban India: A case study in Varanasi

Ingestion of U(nat),226Ra,230Th and210Po in vegetables by adult inhabitants of Bagjata uranium mining area, Jharkhand, India

“…This indicates the partitioning of the elements with accumulation of greater concentrations in the edible portions of leafy or root crops than the storage organs or fruits (Lehoczky et al, 1998;Sharma and Agrawal, 2006;Sharma et al, 2008). Moreover, this is in accordance with the studies from different parts of the world revealed the high accumulation of elements in leafy vegetables which may be attributed to atmospheric deposition (Markose, 1990;Khairiah et al, 2004;Chojnacha et al, 2005).…”

Elemental Profile of Heavy Metals in Garden cress, Coriander, Lettuce and Spinach, Commonly Cultivated in Kahrizak, South of Tehran- Iran

“…Several clinical disorders and physiological problems could arise over their buildup in plant, animal and human tissues (Khan et al 2008). Heavy metals are not degradable substances and continuously accumulate inside the soil over their entrance from effluent wastewater and atmospheric deposition (Sharma et al 2008). In India, plant samples of leafy vegetables in sewage-irrigated area around populated cities were found with high levels of heavy metal contamination including Cd, Zn, Cu, Mn and Pb (Sharma et al 2008;Singh et al 2010;Tiwari et al 2011).…”

“…In the present research, the fields under study were located along side several major Iran's main roads. Heavy metal content of plants often increased with closeness to highways in many populated areas (Delbari and Kulkarni 2014;Sharma et al 2008).…”

“…Heavy metals are not degradable substances and continuously accumulate inside the soil over their entrance from effluent wastewater and atmospheric deposition (Sharma et al 2008).

A deadly amount of heavy metals in vegetable samples collected from Delhi and its surrounding areas in India was also reported (Delbari andKulkarni 2014).…”

“…Industrial activities and various factories have contributed to boosting heavy metal contamination of environmental resources. Reports indicate that their environmental abundance and bioavailability were found to increase to a hazardous threshold (Gyekye 2013;Sharma et al 2008;Girisha and Ragavendra 2006). Agricultural lands were also affected particularly in arid and semi-arid regions, mainly due to application of wastewater as an irrigation source (Souri 2016;Gupta et al 2010;Li et al 2010).…”
