Introduction: Inappropriate management of mining activities may bring about water pollution and pose a heavy complication on aquatic ecosystem and humans. The study aimed to evaluate the effect of Qorveh gold mining activities on the quality of nearby groundwater. Materials and Methods: The concentration of seven eco-toxic metals along with some general hydrochemical parameters were investigated for 27 sampling stations in the study area using Atomic Absorption Spectrometry (AAS) and conventional hydrochemical methods. The analysis results were further applied to compute pollution indices, namely heavy metal pollution index (HPI) for irrigation purposes. Results: The main elements were within the World Health Organization (WHO) and Iranian National Water Standards (INWS) for irrigation water quality, except for NH4+ in some sampling points. The concentration of heavy metals followed the order Cu > Zn > Pb > Hg > Cd > As. The contents of Hg, As, Cd, and Cu in most sites were higher than the recommended values. Except for two stations, the value of HPI based on the mean concentration was found to be far beyond the critical pollution index value of 100, suggesting that the area is highly polluted with some heavy metals. Conclusion: Elevated concentration of trace elements found in groundwater of this area represented the release of harmful elements from gold mining activities on surrounding environment.

Located in Teluk Bayur bay the port is of the five biggest and busiest ports in Indonesia. High sea transportation activities and anthropogenic activities may lead to heavy metal pollution. The purpose of this study was to determine the concentration of Pb and Cu metals, in seagrass (Sargassum sp.) and to analyze the feasibility of consuming Sargassum sp. The method used in this study is a survey method, by analyzing heavy metal at Laboratory Pekerjaan Umum of Riau Province. The water quality temperatures 30-31oC, and salinity of 30-31 ppt, appeared curred velocity 0.06-0.08 m/sec, water transparency 100% with a depth of ± 1 m and pH 7. Pb concentrations the highest is 2.9367 μg/g at stations close to the port and the lowest is 2.2506 μg/g at stations close to tourist areas, and the concentration of Cu metal shows the highest 3.3850 μg/g at stations close to community settlements, and the lowest is 2.7772 μg/g near the port area of ​​Teluk Bayur. Based on the PTWI value, Sargassum sp. those originating from the waters of Teluk Bayur, West Sumatra, are still safe for consumption. Based on the Anova Pb and Cu tests in Sargassum sp. do not different (p> 0.05).
