Air pollution with particulates as measured
at five spots in Vladivostok (maritime and road transport)

Abstract: The impact of automobile and maritime traffic flows on the total concentration of suspended particles (RM) in the atmospheric air of the city of Vladivostok was assessed. In the experiment, measurements were made at five control points with different orographic characteristics and levels of traffic load intensity. Also, air pollution with solid particles emitted by exhaust gases (exhaust) of marine power plants (SSEU) was taken into account.
It is determined that traffic flows are one of the main sources of RM in the atmospheric air of the city of Vladivostok. A differentiated assessment of the level of PM pollution by traffic flows showed that depending on the geographical and climatic characteristics, overall contribution of PM from the OG SSEU to the urban atmosphere is in the range of 15–90%. At two spots closest to the port areas, this value was 70% and 80%. This indicator is almost two times higher than at the control point most remote from port areas.
Keywords: particulate emissions, water transport, exhaust gases from ship installations, particle concentration in air, port city air, particle air pollution.
