SEASONAL VALUES OF THE GASEOUS CONCENTRATIONS OF AIR QUALITY RATINGS IN A RURAL AREA

This study presents the quantities of immission of the selected gas pollutions in the area of a compact development village. Within a range of a one-year research project (2012), the yearly average, seasonal and daily profiles of concentrations of the gas compounds in the air had been determined (SO₂, NO₂ and BTEX). Measures were executed in the area of a rural development and in the areas adjacent to the administrative village periphery. In the seasonal researches a passive method and a GC analytic technique had been used along with an automatic analyser to determine daily NO₂ concentrations. It was found out that an air quality in a rural area is determined by the influence of the local sources (unstructured emission from domestic and farm buildings as well as a communication emission) and a toxicants’ quantity, enriching environment, depends on cyclic weather states, characteristic for a moderate climate. It has been proved that the maximum concentrations of the tested compounds occur in the center of a village development. It has been proved that it was winter emission that influenced the value of a yearly average concentration of pollutions in the air in a most significant manner. Theory concerning parity of a natural and anthropogenic sources affecting the aerosanitary parameters of rural compact settlement area, has been questioned. It has been proposed to introduce an obligatory, temporary indicator monitoring of a compound, which might prove be a nitrogen dioxide
