Despite the protection policies, the ecosystem rapidly become contaminated by a various reasons. Therefore, the level of pollution and its effects on living systems should be monitored at periodic intervals. Heavy metals constitute an important class of aquatic pollutants because of excessive use in many areas, tend to accumulate in the living systems and increased transportation in upper level to the living creatures by food chain. Amanos Mountain's surface waters need to be constantly monitored in terms of pre-defined the stress of environmental pollution on the ecosystem. The heavy metal levels of Al, As, Cd, Hg and Pb which are creates risks for living creatures and unknown of any biological value, and for Cu, Cr, Fe, Ni and Zn which are essential for the living creatures but have harmful effects above a certain level by accumulation will be determined and assess in terms of ecological risks. In this respect, it is determined that there is no risk regionally.
