In this study, the effect of heavy metals on the bean plants have been investigated. Heavy metals cause environmental pollution. Various drugs and fertilizers in agriculture, and in particular fields can lead to heavy metal dirty thereto. Heavy metal elements are essential nutrients for plants.. Normal concentrations of heavy metals serve as a cofactor necessary for the structure of proteins and enzymes that play an important role in plant growth and development. Heavy metals reach various vegetables mixed with various juices and thus these fruits and vegetables are exposed to heavy metals. Heavy metals, usually goes to the plant by mixing industrial waste waters. The studies show that more heavy metal accumulation in plant tissue changes the enzyme activity. In addition, it is reported recently that, the property of heavy metals in plants causes the degradation of hormone balance. In the studies, the existance of Pb, Cd, and Hg in high levels have significantly decreased the cytokine levels in bean seedlings. Heavy metals affect adversely the stability of the cell turgor and cell wall. Also, due to reduced stomatal movement and the leaf area, plant water regime is also affected. Heavy metals are generally accumulated more in plant roots. Skin contact during walking or running people can be seen in heavy metal accumulated soil so that these metals reach the human body through the respiratory tract and ingestion of vegetables grown. Heavy metals, particularly some enzyme activities including amylase activity and reducing the embryos sugar transport and prevents germination as a result of increasing the protease activity

Conclusion: Heavy Metals on Bean Plant can be affected. Key words: Bean Plant; Heavy Metals; Environmental.
