Contamination of freshwater ecosystems in the current situation it is worrying due to limited and due to population growth and urban, industrial and agricultural development around rivers, proper use of water resources seem to be necessary. Today, due to the toxicity of heavy metals, shelf-life and accumulation in the tissues of organisms, ecological and biological importance have much. In the present study tributaries into the river and sewer rural and urban nomads Tea Azerbaijan was considered as a station 10 stations were obtained in this way. In the station using GPS by the use of satellite images of the stations were determined. Its close proximity to each of the stations and the geographic coordinate system. Before entering the city during field operations of three stations, four stations 3 stations within the city limits and outside the city was chosen to determine the pollution load of the river. To evaluate the heavy metals of atomic spectroscopy (A.A.S) is one of the most common methods of qualitative and quantitative measurement of chemical elements (70 elements) were used. For statistical analysis software spss software version 16 and Excel to compare the significant difference between concentrations at different stations used areas of the ANOVA and least significant difference test or Dunnet test was used. In order to evaluate the correlation of metals in water and sediments correlation test was used. The average concentration of lead in sediments, plants, mineral water Olas, Kalalaq, cello house, Kfshan Ivy, terminal, Ceylan tea, City of Knowledge, mansion, Paul King Haider, Tee Janan Lu was calculated (Table 2). The minimum and maximum lead concentration in microgram per gram of dry weight, respectively, 0.03 and 3.8 respectively Ceylan tea and terminal stations respectively. According to statistical analysis, the data is normalized and heterogeneous ANOVA was used to obtain significantly different from that indicated significant differences with each other. The next step was determined using the Dunnett test between stations 7 and 8 there was a significant difference in the concentration of lead deposits. The average concentration of cadmium Drrsvb mineral water stations Olaus, Kalalaq, cello house, Kfshan Ivy, terminal, Ceylan tea, City of Knowledge, mansion, Shah Heydar, Tee Janan Lu in the table (3) was calculated. Stations with minimum and maximum concentrations of cadmium respectively 0.02 and 1.01 micrograms per g dry weight and in stations Kalalaq and knowledge settlements were calculated. According to the normality test and the foci, data was normalized and homogenized to obtain a variance, which showed a significant difference test results have significant differences (0.05 P normality test and 0.05 P normality test and 0.05 P normality test and 0.05 p> homogeate test data normality and homogeneity of variance was used to obtain significant difference test showed that the results have significant differences (0.05 p>). that between stations 1 and 5, 1 and 3, 1 and 10, 2 and 3, 2 and 6, 2 and 7, 2 and 8, 3 and 5, 3 and 9, 3, 10, 4, 5, 4, 7, 4 and 8, 4 and 10, 5, 6, 5.7, 5 and 8, 5 and 9, 6 and 7, 6 and 10, 7 and 9, 7 and 10, 8 and 9, 8 and 10,9 and 10 differences there is a significant.The correlation between sediment and water Pearson correlation test was used for cadmium, lead and copper in water samples with Cu in sediment samples correlated and at 0.01 p = and 0.185 r =, 0.426 r = and 0.613 r = there is a significant difference (table 8). The results of the analysis of sediment samples at various stations nomads river, showed that the stations studied, 5 stations (terminal) while the highest cadmium, lead and copper highest station 7 (City of Knowledge) had accumulated. The minimum amount of lead in the deposition station 6 (Geylan tea) and a minimum amount of cadmium in the sediment Station 2 (bridge Kalalaq) and the minimum amount of copper in the deposition station 3 (Chelokhaneh) have been observed. Station 7 (City of Knowledge) because of domestic waste water chemical fertilizer used in the gardens of the town highest cadmium and copper show. The results of the analysis of water samples at various stations nomads river, indicates that the stations studied Station 1 (mineral water Olaus) the highest level of lead and cadmium is highest at Station 2 (bridge Kalalaq), and the highest copper station 8 (bridge building) shows. While the minimum amount of these elements at station 10 (Janan Lu) have accumulated. This well their role in the purification of water and sediments of heavy metals show.]>
