Subject:
basins; ecosystems; environmental impact; models; nitrogen; nitrogen content; phosphorus; salinity; Baltic Sea
Abstract:
... We report here new data and a mass balance model for 129I in the Baltic Proper and the Bothnian Sea covering the period from November–December 2009. The results showed that the general 129I concentrations in the Bothnian Sea were two-four folds lower than in the Baltic Proper for both surface and deep water. Water exchange between the two basins based on the 129I mass balance model suggests fluxes ...

The mean activity of ¹³⁷Cs and ⁴⁰K was 5.49 Bq kg⁻¹w.w. and 136.6 Bq kg⁻¹ ww respectively. Statistically significant correlation was observed between the ¹³⁷Cs activities in placenta and in herring—the staple food for seals. The concentrations of ¹³⁷Cs and ⁴⁰K were also determined ...

We used plants as indicators to indirectly detect changes in the environment based on changes in species frequencies. Detrended correspondence analysis (DCA) was used to examine if there was a chang ...

Abstract:

In contrast, there are almost no data that allow drawing conclusions about the evolution of plastic pollution in the environment over the past decades. This study investigates the MP load in blue mussels from the North and Balt ...

Therefore, oil spill capability for response and recovery in this area is required to reduce potential oil spill effects. Currently, there are no integrated, scenario-based models for oil spill response and recovery ...

On the Danish, German, and Swedish coasts, about 300 people lost their lives. The consequences of the storm in Denm ...

To test how environmental conditions in the Arctic and the resulting ecological adaptations affect accumulation of persistent organic pollutants (POPs) in the marine food web, bioaccumulation of four polychlorinated biphenyls (PCBs) in an arctic (Barents Sea 77°N-82°N) and a temperate marine (Baltic Sea 54°N-62°N) food web were compared. Three different trophic levels were studied (zooplankton, fi ...
