AIR POLLUTION AT PARKING‐LOTS OF VILNIUS

Abstract

The expansion of Vilnius creates the need for the installation of new parking facilities. This problem could be solved by establishing guarded parking‐lots or modern underground and multi‐storey garages, in order to economize useful land and comply with the requirements of environmentalists. Investigation was carried out on parking‐lots of Vilnius. All the guarded parking‐lots are divided into three types in accordance with the size of the lot and the type of vehicles parked on it. Measurements were carried out at a lot of each type. The concentrations of hydrocarbons, nitric oxide, carbon monoxide and dust were measured. Guarded parking‐lots located at the crossroad of Ateities and L. Giros streets, on Architektu and Č. Sugiharos streets were selected for the investigation. The parking‐lot located at the crossroad of Ateities and L. Giros streets had the highest concentration of nitric oxide overrunning the permitted concentration up to 1,9 times. Besides, the concentration of carbon monoxide and hydrocarbons also overran the permitted norms. The lowest concentrations were found after measuring dust concentration in the air.
