Evaluation of Meteorological Factors Influence on Benzene Accidental Pollution. Case Study: Bacau City 2008

In this paper we analyze the correlation between meteorological parameters (wind speed and direction, relative humidity, air temperature) and atmospheric pollutants in Bucharest during the cold period 26.02.2018-02.03.2018, which was based on the monitoring of the concentrations of nitrogen oxides, NO2, O3 and SO2 sulfur dioxide within 24 h and the occurrence of exceedances above the prescribed limit. It was found based on the results obtained that the wind direction influences not only the concentrations of pollutants but also the correlation between the pollutants. Traffic pollutants were at the highest concentration when the wind speed was low. We have found that the highest average concentration for NO2, NOx, NO, O3 occurred at 90% indicative humidity for vertical mixing of strong pollutants. Sulfur dioxide did not record exceeding over the limit standard in the analyzed period.

“…The concentrations of O 3 , NO x and NO 2 are high due to the high emissions of motor vehicles. There is a high level of pollutants, indicating that the problem of air pollution is in fact regional, not limited to the city's borders [23,24]. Winds can carry moisture or aerosol particles from distant sources [25].…”

“…In urban area, air quality is directly influenced by the type and size of industrial activities, wastes management and all categories of traffic. In the cases of good cities air pollution management plans, the air pollution can be reduced by using strategies to corelate some important influenced factors as: green areas, buildings and population density, roads infrastructure, geographic and climatic conditions [1][2][3][4][5][6][7][8][9][10][11].…”

Considering the air pollution actual issues, in special for the industrial cities, in the present paper were established some correlations between NOx concentration and some climatic factors. The data were obtained from Bacau air quality monitoring stations and are related to 2011. The climatic factors analyzed were air temperature, atmospheric pressure, atmospheric humidity, solar radiation, wind speed and direction. The data interpretations reveal some direct influence of the air NOx concentration dispersion and analyzed climatic factors variation.

“…Air pollution leads to a series of consequences on environment (such as the greenhouse effect, acid rain or changing the ozone layer, odors, reduced visibility and/or product quality decrease) and health (pulmonary diseases, asthma and breathing problems) [1][2][3][4][5][6][7]. Industry has been frequently blamed given the origin of the particulate matter PM10 and along with it, transportation, incineration processes and combustion processes [8][9].…”

Air pollution is one of the major environmental problems with short, medium and long-term effects. Substances emitted into the atmosphere (CO2, SO2, NOx, PM10) contribute to the amplification of the effects of climate change, acidification, air quality deterioration. The most important sources of PM10 emissions come from commercial, institutional and household sectors, industrial processes, road transport and agriculture. In order to protect the atmosphere and improve air quality, are needed measures of control at pollutant emissions. Early pollution reduction actions have led to a significant decrease of PM10 emissions especially from the production and distribution of energy, combustion processes and road transport has significantly diminished. Improving air quality requires continuous monitoring of emissions and, in particular emissions of particulate matter/ PM10. The paper presents the results of the monitoring activity of particulate matter/ PM10 from the thermo-energetic industry. The results of the monitoring include the particulate matter/ PM10 values in the range (68.083 mg/Nm3 - 93.166 mg/Nm3), values that do not exceed the emission limit values.
