The increasing flow of traffic passing through cities on a daily basis, especially those cities that have a difficult situation with bypass, raises concerns about the air quality in sections of the transport corridors, as well as in the city as a whole. Heavy metal pollution is a serious environmental concern, especially in urban and suburban areas where vehicle emissions contribute to air and soil pollution. The aim of the study is to assess the extent of heavy metal contamination in snow samples collected at dif...

In urban environments, human health is increasingly affected by air quality, particularly air pollution with particulate matter (PM), which contains various toxic chemical elements. Car traffic is one of the main sources of air pollution in urban areas, which not only raises dust from roadways but also emits micro particles from diesel engines and tire wear containing heavy metals. The aim of the study is to evaluate the ability of the lichen species Xanthoria parietina, commonly found in Latvia, to biomonitor and...
