Abstract :
As there are mines in Takab, an area situated in the southeast of western Azerbaijan- Iran, and the acidic canals produced in mines and waste dumps as well as layers and marl formations with high permeability around this area, the produced canals provide the conditions of releasing heavy metal elements which will bring about defects on the environment and the rivers of this area. The results of the chemical analyses and the studies indicate that mining activities have affected the natural situation of this area and they have also made several malformations in this area. On the other hand, the climatic rainfalls and the topographical conditions of this area have directed chemicals to penetrate into the area and rapidly contaminate there. Due to the samples taken from two distinct parts of the waste dump, it is indicated that the contamination in this area is mostly caused by chemicals containing arsenic, antihuman and mercury. The southern part of the rivers is highly contaminated. These malformations are mostly observed in sediments and the water of this area. In fact, the regional farming has been deeply affected. As a result, detecting the contaminated areas and proposing alternatives such as making suitable bedding for waste dump establishments and controlling the waste water by building concrete bulkheads can be considered as the most important solution to overcome the aforementioned proble
