Study of the Content of Heavy Metals in Atmospheric Precipitation of the Goygol Region of Azerbaijan

摘要

The increasing content of heavy metals in the soil and atmospheric air can lead to serious consequences and even affect a person. The method of moss biomonitoring was used to define heavy metals in atmospheric depositions. In 2015, the scientists of the Joint Institute for Nuclear Research introduxed moss biomonitoring in Azerbaijan. The first system studies were conducted the same year in the Goygol National Park. Geographical coordinates of the Goygol National Park: 40° 35' northern latitude and 46° 18' east longitude. 50 moss samples were collected (mainly Pleurosium Schreberi), which were studied via neutron activation analysis in the Joint Institute for Nuclear Research in Dubna. In total the content of 44 elements were determined. The concentrations were defined by the instrumental neutron activation analysis (NAA) and atomic-absorption spectroscopy (AAC) in 50 moss samples. Moss species used in the study: Pleurosium Schreberi. The most polluted sites were defined on the basis of the analysis.
