Physicochemical Assessment of the Road Vehicle Traffic Pollution Impact on the Urban Environment

Vehicle traffic pollution requires complex physicochemical analysis besides emission level measuring. The current study is focused on two campaigns of emissions measurements held in May and September 2019 Alba Iulia City, Romania. There was found a significant excess PM2.5 for all measuring points PM10 the most circulated during May, along with VOC CO2 emissions. reveal threshold PM increased values These are consequences environmental interaction traffic. Street dust air-suspended particle samples were collected analyzed to evidence sources. Physicochemical investigation reveals highly mineralized particulate matter: fractions within predominantly contain Muscovite, Kaolinite, traces Quartz Calcite, while Calcite. mineral originate street suspended atmosphere due vehicles’ circulation. A amount soot as small micro-sized clusters fine micro-spots attached over particles, observed by Mineralogical Optical Microscopy (MOM) Fourier Transformed Infrared Spectroscopy (FTIR). GC-MS 53 volatile compounds investigated floating particles that related combustion gases, such saturated alkanes, cycloalkanes, esters, aromatic hydrocarbons. It proves contamination measured matters make them more hazardous health. Viable strategies vehicle traffic-related pollutants mitigation would be reducing occurrence usage modern catalyst filters gas exhausting system.
