The consumption of highly contaminated water and eatables may prove lethal to the human being and may bring genetic disorders. Toxic heavy metals are continuously released to the aquatic bodies in Allahabad as a rapid industrialization. Metals are the problem of magnitude and of ecological significance due to their high toxicity and ability to accumulate in living organisms. Many toxicologists have worked on the analysis and detection of heavy metals in the water bodies, soil, sediments, plankton, fish organs, etc. The main aim of this paper is to provide an in-depth review for the heavy metal concentration in water, fish, sediments, eatables, such as vegetables grown on River beds, etc and to give recommendations to prevent the health hazards against consumption.
