    Interstitial water of deep, stratified lake as potential source of internal phosphorus loading – implications for preventing eutrophication
    (Lviv Politechnic Publishing House, 2019-02-26) Łopata, Michał; Tandyrak, Renata; Augustyniak, Renata; Parszuto, Katarzyna; Płachta, Anna; Cybulska, Zuzanna; University of Warmia and Mazury in Olsztyn
    The paper evaluates the potential impact of internal biogenic pollutants (phosphorus) on the trophic state of the deep, stratified Lake Swiete in Obra, Poland (area 23.3 ha, depth 15.3 m). The amount of phosphorus in interstitial water was analyzed on the basis of spatial studies of 10 cm of surface sediments of bottom sediments. It has been shown that the release of loading accumulated in the water can worsen the trophic state of the lake.

    Spatial and temporal variability of pollutants in the bottom sediments in the northwest part of the Black sea
    (Publishing House of Lviv Polytechnic National University, 2016) Berlinskyi, Nikolai; Safranov, Tamerlan
    The level of pollution of the bottom sediments in the Northwest shelf of the Black Sea is examined. Modern data are compared with those of the late 20th century and their variability over 30 years. Substantial increase (by two orders) of copper, lead and nickel concentration has been marked.
