Accidental Pollution With Ammnonia. Influence of Meteorological Factors

Abstract

Air quality in urban areas mostly depends on the type and size of industrial activities, traffic intensity, municipal and industrial waste management. In addition to these factors, air quality in urban areas also depends on the size and quality of green areas, population density, geographic and climatic conditions. This paper reveals the correlations between air quality aspects in Bacau City, Romania (related to 2011) and the most representative climatic factors that influence the pollutant dispersion. The correlation was made based on data resulted from the analysis of ammonia (NH 3 ) concentrations and their variations in the case of accidental pollutions caused by an important chemical plant located in the south-east of Bacau City, Romania

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

“…Air quality in urban areas depends in particular on the type and size of industrial activities, the traffic intensity and the waste management. In addition to these, in the analysis of urban air quality is also taken in to account the size and quality of green areas, density of population, geographic and climatological conditions [1][2][3][4][5][6].…”

“…In Bacau City, the air quality is monitored by using continuous automatically measurements, performed using two representative stations positioned in a central area and an industrial area [1][2][3][4][5][6].…”

Correlations on the Air Nitrogen Oxides Pollutant Concentration and Climatic Factors Variations in Bacau City

“…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].…”

“…Also, the literature present correlations between some climatic factors, air pollution and human health. The synoptic climatologically conditions influences the NOx air concentration variation in special where the negative effects of traffic are obvious [6][7][8][9][10][11].…”

“…The most used methods for monitoring urban pollution are on-line sensors, positioned by using a specific plan for observing the variation of the concentration of pollutants in all cases of continuous and accidental pollution [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”
