Oro užterštumo tyrimai Vilniaus metalinių garažų aikštelėse

Abstract

The concentrations of CxHy, NO2, CO and dust were investigated in a metallic garage site covering an area of 9.33 ha and having 2650 garages. Modelling of air pollutant spatial distribution over the garage site territory show an increase of pollution at the entry-exit gate, at the central passage of the site and in the area near the Justiniškių street. When the distance from the entry-exit gate increases the concentration of the analysed pollutants decreases.The motor transport traffic in the Justiniškių street and near the garage site increases the concentration of air pollutants in the site territory.
