Abstract

Karaj River is one of the main source of drinking and agriculture water in Tehran and Alborz province, because of so many ecological potentials, this river categorized as a protected river in Iran. For detecting the environmental condition as an annually environmental assessment, concentration of Heavy metals: cadmium, chromium and zinc in the water and sediment were detected in this river. The quality of water determined using Biological value index (Z) as well. By sampling from water, benthos and Sediments from January to July 2018 from different stations along the river. Metals concentrations were measured by ICP device and aquatic insects identified at the lab. The obtained results demonstrated that in both water and sediment samples, there were significant concentration of metals from upstream to downstream stations. In addition, the concentrations of all metals in water and sediment were lower in January than in July. The results of the Z Biological value index revealed significant differences in both seasons between the sampling stations, and the highest values recorded in downstream stations in both seasons. Contamination of Heavy metals, especially in downstream, was due to human interventions such as agricultural, urban and industrial activities and production of wastewaters. In the cold season, because of reduction in population density in the vicinity river area, pollution levels decreased. In general, in terms of water quality index, Karaj River classified in the saprobe class between II-III.
