Snow water pollution, especially from heavy metals, is a growing global environmental concern, as urbanization and industrial activities increasingly contribute to the contamination of precipitation. Snow, acting as a natural filter, accumulates atmospheric pollutants, which are subsequently released during snowmelt, entering stormwater systems and surface water bodies. This issue has been observed across Europe, North America, and other industrialized regions, where heavy metals such as nickel (Ni) and copper (Cu...

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...
