Abstract
One of the main environmental polluters, especially
in large cities of Ukraine, is road transport. In particular, road
transport is one of the main sources of persistent organic
pollutants in the environment. Therefore, monitoring of air
pollution by road transport is one of the most relevant
questions in Ukraine, especially considering its intentions to
join the European Union. Analysis of the regulatory and
legislative frameworks of Ukraine shows that, unfortunately,
today, there are no regulatory documents that motivate to
reduce the load of mobile sources, including road transport,
on the environment. Moreover, even though the only
methodology for calculating pollutant emissions from mobile
sources expired in 2015, no new methodology has been
developed yet. This paper calculates the masses of pollutants
formed during the combustion of gasoline and diesel fuel, and
proves the necessity to take into consideration persistent
organic pollutants when assessing the toxicity of exhaust
fumes, considering their cumulative effect and half-life. The
calculation was performed according to European and national
(Ukrainian) methodologies, which are supplemented by the
calculation of polychlorinated dibenzo-p-dioxins (PCDDs) and
polychlorinated dibenzofurans (PCDFs) formation. Using the
relative hazard factor, the relative masses of these substances
are calculated, the obtained masses of all components of the
exhaust fumes are ranked, the contribution of each component
to the toxicity of emissions is revealed. Using emission factors,
the specific emissions of these persistent organic pollutants
during the combustion of diesel fuel, gasoline, liquefied and
compressed gases are calculated. By the results, the types of
organic fuels with the highest priority for use by mobile
sources are identified.
