Abstract

Heavy metal contamination is a serious threat because of their toxicity, bio-magnification and bioaccumulation in food chain. The deficiency of some of these metal elements leads to impairment of vital biological process but when they are present in excess, they become toxic. Raw bovine milk is considered as one of the food sources contaminated with heavy metals, because cows graze on the grass grown in lands which somehow come in contact with the untreated effluent of industries. Milk is a very important component of human diet. The present study was aimed at investigating the levels of selected heavy metals (Cr, Cd, and Pb) in raw bovine milk produced in Oyam District, Uganda and estimation of potential health risks associated with long term exposure to heavy metal contaminated milk from the said area. Experimental results indicated that the mean concentration levels of the metals were 0.17±0.08, 6.84±2.03 and 0.13±0.05 ppm for Lead, Chromium and Cadmium, respectively for all samples taken from Aber Sub County. The mean concentration levels of the metals were 0.15±0.07, 6.55±1.71 and 0.12±0.04 ppm for Lead, Chromium and Cadmium, respectively, for samples taken from Acaba Sub County. The mean concentration levels of the metals were 0.16±0.07, 6.83±1.74 and 0.15±0.11 ppm for Lead, Chromium and Cadmium, respectively, for samples taken from Loro Sub County. The mean concentration levels of the metals were 0.28±0.18, 8.34±2.92 and 0.19±0.13 ppm for Lead, Chromium and Cadmium, respectively, for samples taken from Kamdini Sub County. The Target Hazard Quotient (THQ) of all heavy metals analyzed (Pb, Cr and Cd) in milk samples was found to be less than 1. Hence it would be inferred that it’s safe to drink the milk from this area.
