Opis:: Water in the Miedwie Lake were the subjects of a five-year study (2008-2010). Total alkaline phosphatase activity was determined seven times a year in these environments. The study on the water demonstrated that the top sublittoral layer (1 m) featured the highest alkaline phosphatase activity among all the analyzed zones. A study of seasonal fluctuations showed that a maximum total alkaline phosphatase activity, both in the water occurred in spring (May) and summer (July, August). Basing on this parameter no increase in eutrophication process in the Miedwie Lake was determined in the course of a 3-year study.

Opis:: 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, but also for fishing, tourist and recreation purposes. Unfortunately, heavy metal pollution is an ever-increasing problem. These toxic heavy metals on entering into the 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. Many of these metals tend to remain in the ecosystem and eventually move from one compartment to the other within the food chain. The increase in residue levels of heavy metal content in water, sediments and biota has resulted in decreased productivity and increase in exposure of humans to harmful substances. Food chain contamination by heavy metals has become a burning issue in recent years because of their potential accumulation in biosystems through contaminated water, soil, sediment and air. The present research work deals with the quantification of toxic heavy metals in the water samples collected from Miedwie Lake (North-West Poland).

Lake of Miedwie (North-West Poland)
Opis:: The present research work deals with the quantification of toxic heavy metals in the water samples collected from Lake of Miedwie (North-West Poland). While the annual average concentration of Cadmium was calculated as 0.45 ppm in 2008 of the year and 0.29 ppm in 2009 of the year. The values obtained were found to be below the permissible limit of 2.0 ppm set for inland surface water. While the annual average concentration of Chromium was calculated as 2.78 ppm in 2008 of the year and 2.50 ppm in 2009 of the year. Which was very much above the permissible limit of 0.1 ppm set for inland surface water. The observed annual average concentration of Copper in the water was 0.06 ppm in 2008 of the year and 0.05 ppm in 2009 of the year, which was below the permissible limit of 3.0 ppm set for inland surface water. While the annual average concentration of Mercury was calculated as 0.04 ppm in 2008 of the year and 0.04 ppm in 2009 of the year, which was very much above the maximum limit of 0.01 ppm set for inland surface water. The annual average concentration of Nickel in the water samples was observed to be 2.19 ppm in 2008 of the year and 2.42 ppm in 2009 of the year, which is close to the limit of 3.0 ppm set for inland surface water. The annual average concentration of Lead in the water samples was observed to be 0.06 ppm in 2008 of the year and 0.05 ppm in 2009 of the year, which is above the permissible limit of 0.1 ppm set for inland surface water. The results of the present investigation indicate that the annual average concentration of Zinc in water samples was 3.25 ppm in 2008 of the year and 2.95 ppm in 2009 of the year, which is above the permissible limit of 5.0 ppm set for inland surface water.
