Heavy metals in the surrounding of mining and metallurgic sites in Lori region in Armenia

This study is focused on the presentation and discussion of data related to contamination by heavy metals in selected locations in the Lori region in Armenia. A complex set of environmental and biological samples were taken and analyzed. Environmental samples were sediments, soil (mostly from vegetable gardens or other agricultural fields) and sand or soil from children playgrounds. Biological samples included human hair and free-range chicken eggs. Environmental samples and human hair samples were analysed for heavy metal content and results of the analytic analysis are reported in this study. Chicken eggs investigation is reported in a separated study.

Introduction

Sampling of environment in and around municipalities Alaverdi, Akhtala, Teghut in Lori region in Armenia took place in July 2018. The aim of the study is to monitor the presence of heavy metals in surroundings of industrial area and to analyze its effects on both human health and quality of the environment. The sampling was followed by chemical analyses of collected samples with focus on heavy metals. Analyses of environmental samples took place at the University of Chemistry and Technology in Prague, Czech Republic, biological samples of human hair were analyzed by The National Institute of Public Health in the Czech Republic.

The evaluation of the influence of copper-processing industry in Alaverdi region to local inhabitants and the environment is part of the study. As potential sources of pollution were discussed Alaverdi copper and molybdenum smelter, copper and molybdenum mines in Akhtala and Teghut and tailing dams in Akhtala, Teghut and Mets Ayrum. The study follows up and continues in the work of previously published studies and expands their findings with sediments and some areas which were not monitored.
