| Abstract: | Samples of coal, slag, emissions retained on the separating devices, fly ash, aerosols and hair taken in the area of coal-fired power plant were analyzed by means of instrumental neutron activation analysis. 13 to 23 elements were determined in the samples. The data obtained for emissions and aerosols were further evaluated by calculation of enrichment factors, correlation coefficients and by the ratio matching method. The concentrations of elements determined in the hair of exposed group were compared with the data of control and out control groups as well as with the recent data found for hair in other countries. It can be seen from the results that arsenic is the most serious pollutant in the area. |
