Plastic waste pollution represents extensive threats to ecosystems and human health. A lot of plastic waste enters the ocean or ends on landfills, where it threatens the ecosystem. Therefore, it is crucial to find methods for its effective disposal or reuse. A significant amount of plastic can be found in personal protective equipment used to protect against viral infections and transmission, for example during the COVID-19 pandemic. This article focuses on the utilization of plastic waste by mixing it with beech ...

ASSESSMENT OF HEAVY METAL CONTAMINATION IN URBAN SNOW: A CASE STUDY OF NICKEL AND COPPER IN JELGAVA, LATVIA

(STEF92 Technology, 2024-12-15, Jovita Pilecka-Uļčugačeva, Anda Bakute, Māris Bērtiņš, Kristaps Siltumens, Inga Grīnfelde)

Show more

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...

Well-aerated soils are essential for methane (CH4) uptake from the atmosphere, acting as significant sinks for this greenhouse gas, which has a global warming potential 25 times greater than that of carbon dioxide (CO2). These soils contain methanotrophic bacteria, which oxidize CH4 and thereby reduce atmospheric methane concentrations. The potential of soils to assimilate CH4 depends on factors such as soil type and moisture regime. This study investigates the ability of clay soil Cambic Calcisol to assimilate CH...
