Heavy Metal Pollution: Copper

One of the biggest problems of the world is environmental pollution due to development of technology and increase of population. Heavy metal pollution is one of element of pollution. Heavy metals are released to environment (water and soil) because of industrial, agricultural and mining activities. For example copper sulfate has been used for fungal disease control in viticulture in Portugal and in aquaculture in Turkey. Copper is discovered in the aquatic habitats collecting runoff water from this agricultural area [1]. Cooper is also found in some areas contaminated by domestic wastes such as mining, smithery, waste incinerators, thermal reactors generating power from coal and construction materials used for buildings [2]. Heavy metals accumulate in the aquatic organisms. Especially, it is found that they accumulate in different amount and different tissues of fish. There are many literatures about it [3-6]. Heavy metals enter the food chain in aquatic ecosystems and it increases in it. Then they could be dangerous to human, which is the top of the food chain [7].
