The paper presents the assessment of the water condition of the Łękawka stream according Water Framework Directive, carried out on the basis of research on benthic macroinverte-brates and the analysis of data on other indicators used in the monitoring of waters. Sampling of macroinvertebrates, taxonomic identification and calculation of the MMI_PL index were car-ried out in accordance with the Multi-Habitat...
The formation of sludge is an inevitable consequence of wastewater treatment processes and their disposal and utilization requires knowledge, technology and engineering. Sulfate radical-based advanced oxidation processes (SR-AOPs) are gaining popularity as a fea-sible alternative for sludge conditioning and removing recalcitrant pollutants in an aqueous environment. Application of the pretreatment...
The studies on bird mortality along 12 transparent acoustic barriers near roads in Bielsko-Biala (Poland) were conducted from March to October in 2017. The aim was to characterize avifauna striking glass barriers and to relate frequency of collisions to time, developmental stage, sex, vicinity of noise barrier. During the breeding season of birds, 102 collisions of birds with screens, belonging to...
