Spatiotemporal variation of soil heavy metal contamination in urban intersection areas and the vicinity of a former military missile base in Raseiniai district, Lithuania
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)The accumulation of heavy metals (HMs) in urban and protected area soils results from multiple anthropogenic emission sources, including vehicular traffic and historical land use. This study aimed at evaluating the levels ... -
Effectiveness of water treatment processes in removing precursors of chlorinated organic substances from mixtures of groundwater and surface water
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)Due to the correlation of UV254 and UV272 absorbance with the formation of oxidation and disinfection by-products, it is a very important indicator in assessing the effectiveness of water treatment processes. The aim ... -
Investigation of the removal of cations from aqueous solutions using sapropel
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)Sapropel is a sediment found at the bottom of lakes, consisting of both organic and inorganic materials. Water contains various cations, such as ammonium, calcium, and magnesium, which are generally harmless to human health; ... -
A novel thermal criterion for bubble destruction in hydrodynamic cavitation: numerical modeling and experimental validation
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)This research investigates the conditions precipitating the surface instability of spherical bubbles and develops a novel thermal criterion for their terminal collapse during hydrodynamic cavitation. A new mathematical ... -
