1. IntroductionHeavy metal is a generic term for metals commonly with a specific gravity of 5 or more, and can be deposited by hydrogen sulfide in an acid solution, such as iron, manganese, chromium, copper, mercury and cadmium. The specific gravity is the term of the ratio of the mass of a substance to the mass of a standard substance which has the same volume with the substance. Even small amounts of heavy metals are harmful to the environment and the human body.
Among the heavy metals, copper is often encountered and considered a major environmental pollutant because it is highly toxic. When heavy metals are released into the environment, they circulate in the biosphere and can cause damage to living things along the food chain, and sometimes cause pollution-related diseases (Erickson et al 1996). If even a small amount of heavy metal is stored in the body, they can damage the body's health over a long period of time since the heavy metals are not excreted and accrue to the body's protein.
