Abstract

Background and Objective: Heavy metals contamination, particularly in aquatic environments, is an important concern. Since Mahbad river is the source for supplying drinking water to the city and the dam established on it is used for catching Fish and sale in the market, Heavy metals concentrations in the Sediments of Mahabad river and the Dam, and the possible health risk of the Fish consumption were investigated. Materials and Methods: Sediment samples from 21 sites in Mahabad dam, and river, and 16 Fish samples (Sander lucioperca and bramis brama species) were collected. After preparation, the samples were analyzed using ICP-MS method. For data analysis, enrichment factor (EF), potential ecological Risk index (RI), health risk indices, principal component analysis (PCA) and Mann-Whitney test were used. Results: The EF and RI values of the studied Heavy metals in the Sediments were low. The max concentrations of lead, zinc, copper, arsenic and manganese were 36, 162, 74, 22. 8 and 3221 mg/kg, respectively. This was more obvious in the samples taken from the downstream of the dam. However, accumulation of the Heavy metals in Fish tissues resulted in high values for total hazard quotients (THQ), particularly for As (1. 19); high hazard index (above 1); and high estimated daily intake (EDI) for copper (1. 64) in the study area. Conclusion: The results of this study revealed that the conditions for elements’ mobility and bioavailability was suitable in the river and Mahabad Dam. Therefore, assessing the mobility and bioavailability of the Heavy metals in the Sediments of the region, and measurement and continuous monitoring of the Heavy metals concentrations in the water, Sediment and Fish of the study area are needed.
