Heavy metals in the waters of Dąbie Lake (North-West Poland) in the years 2008-2012

Piotr Daniszewski

World Scientific News > 2017 > 69 > 75-85

Heavy metal pollution is an ever increasing problem of our lakes. These toxic heavy metals entering in aquatic environment are adsorbed onto particulate matter, although they can form free metal ions and soluble complexes that are available for uptake by biological organisms. The increase in residue levels of heavy metal content in water, sediments and biota has resulted in decreased productivity...

Heavy metals in water of Miedwie Lake (West Pomeranian, North-West Poland) and their potentiality in health risk assessment

Piotr Daniszewski

World News of Natural Sciences > 2017 > 14 > 79-89

Miedwie Lake is the biggest post-glacial lake of the West-Pomeranian Voievodship. At the same time it is the fifth of the largest lakes in Poland. Miedwie Lake is situated centrally between three big agglomerations, i.e. Szczecin, Stargard Szczecinski and Pyrzyce. Miedwie Lake has been since 1976, the potable water source for the City of Szczecin. The reservoir is used not only for municipal purposes,...

Renewable energy sources today and tomorrow

Janusz Wilas, Robert Maśniak, Piotr Daniszewski, Paula Jadczak

World Scientific News > 2016 > 60 > 103-112

Renewable energy sources (RES) have significant potential to contribute to the economic, social and environmental energy sustainability of small islands. They improve access to energy for most of the population, they also reduce emissions of local and global pollutants and they may create local socioeconomic development opportunities. A majority of the communities around the world rely heavily on...

Nutrient, chlorophyll, and water clarity relationships in Baltic Sea nearshore coastal waters with comparisons to freshwater lakes Barlinek Gorzów Landscape Park (North-West Poland)

Janusz Wilas, Piotr Daniszewski, Emil Cyraniak, Beata Draszawka-Bołzan

World Scientific News > 2016 > 57 > 737-746

Models relating chlorophyll to nutrients and Secchi depth to chlorophyll using data from nearshore coastal waters of Baltic Sea were successfully developed. The models suggest that phosphorus is the primary limiting factor for phytoplankton in the nearshore coastal waters of Baltic Sea and that total phosphorus concentration accounts for 65% of the variance in chlorophyll concentration. The models...

Janusz Wilas, Beata Draszawka-Bołzan, Emil Cyraniak, Piotr Daniszewski

World News of Natural Sciences > 2016 > 3 > 19-25

In spite of widespread support from the population of most member countries for European Union policy, including support for sustainable development, in many EU countries, the levels of acceptance of new environmental protection programmes have been and, in particular in new member states, still are considerably low. The experience of the countries which were the first to implement union directives...

Characteristics of the trophic status, vulnerability to degradation, habitat conditions ichthyofauna and bioconcentration factors of lakes in the Barlinek-Gorzów Landscape Park

Piotr Daniszewski

World News of Natural Sciences > 2016 > 5 > 42-49

Urbanization is the cause of many changes which are taking place in the environment, including those found in the catchment. With this in mind, it is an important issue to properly protect water reservoirs and also take action to counter the adverse effects of human activities on the natural environment, including water bodies. To address the increasing degradation of surface waters in the European...

Wastewater treatment technologies

Janusz Wilas, Beata Draszawka-Bołzan, Piotr Daniszewski, Emil Cyraniak

World News of Natural Sciences > 2016 > 4 > 33-43

The article presents an application of multi-criteria analysis for selection of the best treatment technology and the best technical solution to the running of a large and a small wastewater treatment plant. The calculations performed for two plant capacities and for various effluent standards are based on a compromise programming method. The effluent standards considered for the smaller plant are...

Nature 2000 - selected issues

Beata Draszawka-Bołzan, Emil Cyraniak, Piotr Daniszewski

World News of Natural Sciences > 2015 > 2 > 1-6

The EU Nature 2000 network is generally not a network of strictly protected areas in which no economic activities should take place. Therefore, in most Nature 2000 sites, a strict wilderness approach will not be the most appropriate form of management. This guidance document should therefore not be interpreted as the Commission aiming to turn all Nature 2000 sites into wilderness areas. However, in...

Total alkaline phosphatase activity (ALP-EC 3.1.3.1) of water in the River Odra estuary (North-West Poland)

Piotr Daniszewski

World News of Natural Sciences > 2015 > 1 > 1-9

The Odra estuary includes, as its major part, the brackish Szczecin Lagoon. This consists of two parts: the Kleines Haff (located in Germany) and the Wielki Zalew located in Poland. The Lagoon receives the River Odra water supplied from the south; prior to being discharged into the Lagoon, part of the Odra flow passes through Lake Dąbie. In its northern part, the Lagoon connects – via three straits...

Piotr Daniszewski

World Scientific News > 2013 > 1 > 9-13

The role and significance of nature protection for sustainable regional development: Jobs and ecology. The integration of political, economic, and social courses of action, on the one hand, and the nature conservation and basic environmental sustainability, on the other, are crucial for socioeconomic development. This strategy helps to protect the natural environment, and preserve biological and ecological...

World Scientific News > 2013 > 2 > 1-11

The emergence of the Baltic Sea cemented the Scandinavian ice sheet. The sea began to form at the end of the Vistula glaciations when meltwater from the glacier began withdrawing accumulate on today Gdańsk Bay and expanding, with time its surface. Around 10,200 years ago, there was a freshwater lake ice is also supplied with water running off lying to the south. After this period, the rapid warming,...
