Contamination of soil with heavy metals from industrial effluent and their translocation in green vegetables of Peshawar, Pakistan

Abstract

Heavy metal pollution is a serious problem in countries like Pakistan, claiming soil, water and food resources due to negligence and no treatment.

A Review of Environmental Contamination and Health Risk Assessment of Wastewater Use for Crop Irrigation with a Focus on Low and High-Income Countries

“…High concentrations of Cr, Cd, Co, Pb, Cu, Zn, and Ni were reported in spinach, cabbage, radish, and forage grasses when grown on sewage sludge-amended soils [ 208 , 209 ]. Similarly, the wastewater-induced increased accumulation of PTEs by vegetables than the allowable level by EU standards has been reported in Harare-Zimbabwe [ 205 ], Bejing-China [ 20 ], the industrial zone of Faisalabad-Pakistan [ 210 ], Varanasi-India [ 187 ], and Peshawar-Pakistan [ 70 ].…”

The synthesis of nitrogen and sulfur co-doped graphene quantum dots for fluorescence detection of cobalt(ii) ions in water

“…24 Contamination of soil and water with heavy metals such as lead (Pb), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), and mercury (Hg) is an environment issue on a global scale and becoming increasingly significant as a result of the increase of heavy industries. 25,26 Cobalt ions (Co 2+ ) are a significant, water soluble heavy metal contaminant. In trace amounts they are an essential element in human biology with roles including as a component of cyanocobalamin (vitamin B 12 ) and cobalt-containing co-enzymes.…”

Aspergillus Flavus reprogrammed morphological and chemical attributes of Solanum lycopersicum through SlGSH1 and SlPCS1 genes modulation under heavy metal stress

“…Quite recently, it has been noticed that the main crops of the Mardan region have been significantly affected by the HMs due to fast-growing industrialization (Amin and Ahmad 2015). The study was further confirmed by Hussain et al (2013), who showed that the people of Mardan and nearby areas are exposed to HMs through consumption of contaminated vegetables, especially S. lycopersicum.…”
