Heavy metal contamination of soil and vegetables in suburban areas of Varanasi, India.
TLDR
The study concludes that the use of treated and untreated wastewater for irrigation has increased the contamination of Cd, Pb, and Ni in edible portion of vegetables causing potential health risk in the long term from this practice.About:

Health risks of heavy metals in contaminated soils and food crops irrigated with wastewater in Beijing, China
TL;DR: It is highlighted that both adults and children consuming food crops grown in wastewater-irrigated soils ingest significant amount of the metals studied, however, health risk index values of less than 1 indicate a relative absence of health risks associated with the ingestion of contaminated vegetables.

Remediation techniques for heavy metal-contaminated soils: Principles and applicability
TL;DR: In this article, a comprehensive assessment indicates that chemical stabilization serves as a temporary soil remediation technique, phytoremediation needs improvement in efficiency, surface capping and landfilling are applicable to small, serious-contamination sites, while solidification and vitrification are the last remediation option.
Journal ArticleDOI
Assessing risk of heavy metals from consuming food grown on sewage irrigated soils and food chain transfer.
TL;DR: Partitioning pattern of soil revealed high levels of Zn, Cr, and Cu associated with labile fractions, making them more mobile and plant available, and human risk was found to be high for Zn followed by Cr and Pb with special reference to leafy vegetables particularly spinach and amaranthus.
Journal ArticleDOI
Health risk assessment of heavy metals via dietary intake of foodstuffs from the wastewater irrigated site of a dry tropical area of India
TL;DR: The study suggests that wastewater irrigation led to accumulation of heavy metals in food stuff causing potential health risks to consumers, and heavy metal contamination in the wastewater irrigated site presented a significant threat of negative impact on human health.
Journal ArticleDOI
Heavy metal accumulation in vegetables irrigated with water from different sources
TL;DR: The results indicated a substantial build-up of heavy metals in vegetables grown in wastewater-irrigated soils as mentioned in this paper, and the values of these metals were below the recommended maximum tolerable levels proposed by the Joint FAO/WHO Expert Committee on Food Additives.
