1.1 BACKGROUND OF STUDY
Heavy metal refers to any metallic chemical element that has a high density and is toxic or poisonous at low concentrations (Ojovan & Lee, 2005). According to Ojovan and Lee, heavy metals include mercury (Hg), cadmium (Cd), arsenic (Ar), chromium (Crow), and lead (Pb). Heavy metals are natural components of the Earth’s crusts; they cannot be degraded or destroyed. They can enter human body in various ways including via the appliances of cosmetics on our body. Some heavy metals are essentials for the metabolism of our body. But too high concentration of the metals can lead to poisoning on the body system too. When talked about the danger of heavy metals, we are talking about the bioaccumulation that heavy metals can do

LITERATURE REVIEW
2.1 HEAVY METALS
Heavy metals are metallic chemical element that has a relatively high density and is toxic or poisonous at low concentration (Ojovan & Lee, 2005). Heavy metals like Pb, Cd, Hg, As, Se and Zn are categorized as first class of hazard. The sources of heavy metals are industrial sources including present and former mining activities, foundries and smelters and diffuse sources such as combustion by products and traffic fumes. Most of the heavy metals are essential to plant and animal growth as trace elements in order to maintain biological functions (Pam & Brian, 2007). This has mad them to be environmentally significant. Heavy metals can be abundance in some soils and environments where they sometimes occur in rocks or are concentrated by natural

Arsenic is toxic to humans and animals. Even in low doses, arsenic can produces nausea, vomiting and diarrhea. Larger doses of arsenic can cause abnormal heart beat, damage to blood vessel and a feeling of “pins and needles” in hands and feet. It may develop small corns or warts on the palms of hands and soles of feet. Direct contact with the skin can cause redness and swelling too (Rank, 2010). Arsenic may be good as complexion refresher, but long time exposure to it can cause cancer. If arsenic is swallowed, cancer is likely to develop in bladder, kidneys, liver and lungs. Arsenic, in a simple word, can cause death (Rank,
