CRISTINA MIHAELA BALACEANU, MIHAELA ANDREEA MITIU, MARIA IULIANA MARCUS, MARIANA MINCU POLLUTION IMPACT OF THE GROZAVESTI THERMOELECTRIC POWER PLANT ON THE URBAN AGGLOMERATION BUCHAREST The purpose of this paper is the experimental analysis of the thermoelectric power plant Grozavesti impact on Bucharest urban agglomeration for year 2015. Experimental research is done for the NOx and SO2 pollutant for all seasons. The thermoelectric power plant Grozavesti is located near the Botanical Garden. Data provided by the industrial source are processed and constitute the input for the determination of the NOx and SO2 concentrations by using the OML (Operational Local Model) air quality dispersion Gaussian model. The results from modelling shows that the highest NOx and SO2 concentrations occur in the winter and autumn periods, due to unfavorable meteorological dispersion conditions and due to the operation of thermal power plant Grozavesti in the cold seasons. Thermoelectric power plants Grozavesti, operate on natural gas, because power plant have been refurbished. Generally, the results show that the industrial power plant represent the main contributions for pollution when the NOx and SO2 are exceed the limit value, according to Law 104/2011- ambient air quality, and this affect vegetation and human health.
