Heavy metal is used to refer to metals and semi-metals with a density of more than 5 gr/cm3. The rapid developments of the new technologies in numerous projects and soil contamination by heavy metals, make the soil structure poisonous for plant growth and development, and they all damage the soil biodiversity. Water is also essential for the survival of all living organisms, but unfortunately sources of water used in industries are suffering from all kinds of pollution. The aim of this study is to review the level of food contamination with toxic heavy metals in world. This study was a descriptive overview with entry criteria, relevant information and the keywords of the research.
Heavy metals such as Zn, Pb, Fe, Ni, Co and Cu are abundant in the environment and contribute greatly to the stability and balance of ecosystem processes. However, the fact that they are in excess pollutes the food chain and then becomes a source of poisoning for humans and the entire ecological function. This is an important problem in the study of ecology and geochemistry.
