Comparative studies of heavy metals in wheat growing in different environmental conditions

In the present investigations,we screened wheat crops,collected from different areas of peshawar and found that the level of heavy metals like zn,cu,cr,mn cd,ni,pb and fe in crop increases parallel to the extent of pollution. wheat crop irrigated with industrial effluents accommodate high levels of heavy metals than those irrigated with municipal sewage and irrigated with tube well water. the aim of the study is to aware the public of the possible contamination and ensure that they avoid consumption of crops if grown near industrial dumps or other heavily contaminated places.
