Identification of toxic metal deposition in food cycle and its associated public health risk

ood chain contamination by heavy metals has become

a critical issue in recent years because of their potential

accumulation in bio systems through contaminated water,

soil and irrigation water. Industrial discharge, fertilizers,

contaminated irrigation water, fossil fuels, sewage sludge and

municipality wastes are the major sources of heavy metal

contamination in soils and subsequent uptake by crops. The

main objectives of this project were to determine the levels of

minerals, trace elements and heavy metals in major foods and

beverages consumed by the poor and non-poor households

of Dhaka city and assess the dietary risk exposure to heavy

metal and trace metal contamination and potential health

implications as well as recommendations for action. Heavy

metals toxicity depends on several factors including the dose,

route of exposure, and chemical species, as well as the age,

gender, genetics, and nutritional status of exposed individuals.

Because of their high degree of toxicity, arsenic, cadmium,

chromium, lead, and mercury rank among the priority metals

that are of public health significance. These metallic elements

are considered systemic toxicants that are known to induce

multiple organ damage, even at lower levels of exposure.

This review provides an analysis of their environmental

occurrence, production and use, potential for human exposure,

and molecular mechanisms of toxicity, and carcinogenicity.
