The increased pollution has affected the quality of soil, air and water resulting in the contamination of food and causing serious problems to human health in all over the world. For example the intake of trace heavy metals in excess quantities by the consumption of contaminated food grown in polluted soil or by polluted water. Fruits and their juices are the part and parcel of the daily human lives. And these are one of the affected by the heavy metal toxicity. This study presents how much amount of heavy metals are present in commercially available fruit juices and not been safe for human use.
