Habitat-related patterns of soft-bottom macrofaunal assemblages in a brackish, low-diversity system (southern Baltic Sea)
PublicationCoastal areas provide a high variety of sedimentary habitats that influence the structure of resident fauna even on small geographical scales. Therefore, examinations of spatial variations in benthic assemblages require background knowledge of the environmental and biotic heterogeneity of habitats in order to understand ecological processes in such areas. The effect of habitat-related abiotic and biological variables on macrofaunal...

Mobility and bioavailability of mercury in sediments of the southern Baltic sea in relation to the chemical fractions of iron: Spatial and temporal patterns
PublicationMarine sediments play a significant role as reservoirs for mercury (Hg), a bioaccumulative toxic pollutant that poses risks to human and ecosystem health. Iron (Fe) has been recognized as an influential factor in the complexation and bioavailability of Hg in sediments. However, limited studies have investigated the interactions between the chemical fractions of these elements in natural settings. This study aims to examine the...

Ograniczenie zanieczyszczeń odprowadzanych do Bałtyku przez rozwiązania zrównoważonej gospodarki wodno-ściekowej na obszarach wiejskich
PublicationMorze Bałtyckie jest prawie całkowicie zamknięte. W każdym roku tylko 3% objętości wody ulega wymieniane. Dlatego okres całkowitej wymiany wody w morzu jest bardzo długi i wynosi 25-30 lat. Powoduje to nagromadzenie dopływających zanieczyszczeń i przyczynia się do eutrofizacji. Czynnikami odpowiedzialnymi za eutrofizację są związki biogenne, przede wszystkim związki azotu i fosforu. Jeśli chodzi o zasilanie wód Bałtyku związkami...
