Heavy metal contamination affects physiology, immune system and reproductive potential of organisms from microscopic level to higher trophic levels.Biomagnifications along the food chains create concern to human exposure and associated health risks on regular consumption of these heavy metals.Direct sewage discharge and untreated waste disposal in open waters make aquatic organism more prone to heavy metal exposure.This study focuses on analysis of two heavy metals (Lead and Cadmium) into the muscle tissue of fish species, Labeo rohita (Rohu) which was collected in a municipality of Jaipur district, Rajasthan in the month of September and October, 2023.Rohu is a preferred choice among the fish-eating population because it is cheaper and tastier in comparison to other varieties of fishes being produced and sold in the area.Fishes were dissected and processed through Wet Digestion Method for extraction of heavy metals.Further analysis was done using Atomic Absorption Spectroscopy.Both lead and cadmium were present in higher amount than the permissive limit of the Joint Food and Agriculture Organization of the United Nations and World Health Organization (FAO/WHO).Target Hazard Quotient (THQ) was calculated to be <1 limiting the value of Hazard index (HI) and Target Cancer Risk (TCR) to be negligible for the concerned area.This research indicates that in order to prevent future metal contamination, effective preventive measures must be implemented.Further studies with large sample size must be done in the area to access the contamination of other heavy metals including mercury, chromium, arsenic etc.
