Mosses-Bioindicators in the Environmental Monitoring of Air Pollution by Metal Ions and Radionuclides

The purpose of our research was to identify the degree of air pollution with ions of mettals and radionuclides using moss bioindicators. For the studied samples of moss and soil near Mingechaur, Baku to identify the bioindicator properties of moss and for bioindication of air and soil. Concentrations of heavy metals were determined on an Agilent Technologies 7500 Series ICP-MS (7500cx) instrument using inductively coupled plasma mass spectrometry (ICP-MS, USA). The activity of radionuclides were determined on Gamma spectrometer "Canberra" (USA)γ-spectrometer with high a purity germanium detector (HP Ge). The content of metal ions in the studied samples collected from the least polluted territory of the city of near Mingechaur, which amounted for moss samples: Cd (0.19689), (Cu (59.19030), Ni (18.746), Pb (62.40856), Zn (50.11554) and Hg (0.060154); for soil samples - Cd (1.07352), (Cu (23.24958), Ni (20.33940), Pb (27.45685), Zn (12.11554) and Hg (0.059426) mg / kg, respectively. The content of heavy metals in the studied samples collected from the most polluted area nearthe city of Sumgait was experimentally determined, and for samples of mosses, they were Cd (0.61976), (Cu (64.28251), Ni (22.75801), Pb (65.70956), Zn (167.50293) and Hg (0.091319); for soil samples, Cd (0.29681), (Cu (27.61957), Ni (25.669), Pb (28.596), Zn (87.10275) and Hg (0.090798) mg / kg, respectively. It was determined the activity of radionuclides (7Be, 40K, 60Co, 208Tl, 134Cs, 137Cs, 210Bi, 212Bi, 212Pb) in the samples of of moss, soil and water samples taken from the Mingechaur region and in Baku region of the Azerbaijan Republic. As a result of the research it was revealedе the activity of 40K was more than other isotopes (648,1 Bq/kg). It was found out 7Be of activity 79.08 Bq/kg, 214Pb of activity 62.62Bq/kg, 214Bi of activity 28.74 Bq/kg, 137Cs of activity 14.01 Bq/kg, 134Cs of activity 12.15 Bq/kg, 60Co of activity 11.34 Bq/kg and oters, which were more in Mingechaur region than in Baku.
