Abstract
In an urban environment the typical anthropogenic sources of benzene are
mainly the road traffic. Other important sources are petrol stations and smallscale
industries using benzene as a solvent, such as the printing industry, etc.
Petrol stations are the most significant of these additional sources. Evaporative
emissions from petrol station operations include contributions due to the filling
underground tank operations, due to the underground tank breathing and
emptying, due to vehicle refuelling operations and lastly due to spillage. The
petrol stations are frequently located in populated urban areas consequently
exposing the population to this kind of pollution. The present study assesses the
contribution of petrol stations to the ambient benzene concentrations in a midsized
city. The scientific toolbox adopted to develop the studies includes an air
quality simulation model and a GIS platform. Based on the method and the rate
of filling, tank configuration and gasoline properties the evaporative emissions
from petrol stations are calculated. This paper aims at presenting the approach,
including the theoretical framework, and at discussing the results and their role
within the city's quality of life argument.
