An overview to the results from the application of various spectrometric (atomic absorption spectrometry, AAS; inductively coupled plasma – atomic emission spectrometry, ICP-AES; and inductively coupled plasma – mass spectrometry, ICP-MS) and radioanalytical (neutron activation analysis, NAA) techniques in environmental pollution studies in the Republic of Macedonia are presented. The results from the surveys of the pollution with heavy metals of soil, air and food are reported. The pollution with heavy metals in the particular regions was additionally investi-gated using moss, lichens, attic dust, soil, water and sediment samples. The results from the study of the pollution in the cities of Veles (lead and zinc smelter plant), Kavadarci (ferronickel smelter plant), Radoviš (copper mine and flo-tation), Probištip, Makedonska Kamenica and Kriva Palanka (lead and zinc mines and flotation plants) and Bitola and Kičevo (thermoelectric power plants) are presented.

The paper presents the results of a comparative assessment of the degree of pollution of subtropical brown soils with a number of heavy metals (V, Mo, Co) and arsenic in the zone of influence of solid municipal waste landfill “Sharra”. The landfill is located about 7 km southwest of the center of Tirana. Until the early 1990s it was used mainly for the disposal of industrial waste, subsequently it became an uncontrolled open dump and is now the dumping area for all waste of the capital city of the Republic of Albania. Total metal and As contents were determined by inductively coupled plasma atomic emission spectrometry in samples from 14 sites at different distances from the landfill body. Concentrations of V - in 1.2-1.3 times, Mo - more than in 2.2-4.4 times, Co - in 1.2-1.5 times and As - more than in 3.4 times were exceeded background concentration. It was also revealed 1.7 times higher than the established normative value for As in soils. The obtained results confirm the hypothesis about the negative impact of the Sharra landfill on the adjacent territories.

Atmospheric deposition rates of heavy metals (As, Cd, Co, Cu, Hg, Mn, Ni, Pb, and Zn) were determined from July 2009−December 2010 in downtown Toronto. Atmospheric deposition samples were collected using samplers with plastic, glass and water surfaces from two rooftops (15 m and 59 m above ground) in the city core of Toronto. Mercury species were analyzed using Cold Vapor Atomic Fluorescence Spectrophotometer (CVAFS) and the rest of metals were analyzed by acid digestion combined with Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The results showed that the deposition of heavy metals was higher on water surface as compared to both the plastic and glass surfaces and that Cu, Mn, Pb and Zn showed higher deposition rates as compared to As, Cd, Co and Ni. The deposition rates were higher on Kerr Hall North (KHN) site indicating contribution from local sources. For total mercury (THg) and methyl mercury (MeHg), the deposition rates were higher on Jorgenson (JOR) site as compared to KHN site.
