AIR POLLUTION STUDY FOR BULGARIAN PART OF BULGARIA-ROMANIA TRANS-BORDER AREA

Abstract

A BSTRACT : The paper presents statistical analysis of air pollutants in the Bulgarian part of trans-border BG–RO area. Air contamination charcteristics and norms are also presented and commented in the present survey. Ecological monitoring system in the BG–RO trans-border area is described. Particulate matter (PM), nitrogen dioxide (NO 2 ) and ground-level ozone (O 3 ) , are now generally recognised as the three pollutants that most significantly affect human health. Because of this, further in the paper concentration levels of these three pollutants are statistically studied, based on official monitoring data. Re-sults are graphically presented and commented. Ambient air quality in the BG–RO trans-borer area is better today than it was two decades ago, but despite improvements, pollutant levels still show significant adverse effects on human health and the environment. To improve air quality in the future, it will be necessary to increase the use of ”green” and more efficient technologies in terms of thermal insulation of buildings, as well as the use of alternative sources of fuel in the household and transport, use of best available technology in the industry, green roofs in urban areas and more. Also it is nessessary more precise mathematical modeling of the data series, which take into account more factors to be developed and used for better understanding and forecasting the air contamination processes.
