Between 1996 and 2016 the activity of alkaline phosphatase in the littoral water of Lake Piaseczno was researched in fiveyear measurement cycles. Samples of water from the area corresponding to the agricultural sector of the lake catchment area were used as the research material. Simultaneously, the content of nitrogen and phosphorus compounds in the soils of the agricultural sector of Lake Piaseczno was investigated. Between 1996 and 2006 the activity of alkaline phosphatase in the water under study was similar and exhibited a slight increasing tendency. In the consecutive measurement cycles (2011 and 2016) the activity of the enzyme in the water increased significantly. The research also proved that every year the content of mineral forms of nitrogen and assimilable phosphorus in the soil surrounding the lake tended to increase. The enzymatic parameter under study was used as an indicator of lake eutrophication. The research revealed that during the period under analysis the trophicity of Lake Piaseczno increased.

W latach 1996-2016, w 5-letnim cyklu pomiarowym, badano aktywność fosfatazy zasadowej w wodzie litoralnej Jeziora Piaseczno. Obiektem badań były próbki wody pochodzące z obszaru odpowiadającego sektorowi rolniczemu zlewni jeziora. Równolegle badano także zawartość związków azotu i fosforu w glebach przybrzeżnych sektora rolniczego Jeziora Piaseczno. W latach 1996-2006 aktywność fosfatazy zasadowej w badanych wodach utrzymywała się na zbliżonym poziomie, wykazując niewielką tendencje wzrostową. Natomiast w kolejnych cyklach pomiarowych (2011 i 2016) zanotowano istotny wzrost aktywności tego enzymu w badanej wodzie. Wykazano także wzrastającą z roku na rok zawartość mineralnych form azotu i fosforu przyswajalnego w glebie przybrzeżnej jeziora. Opierając się na badanym parametrze enzymatycznym jako jednym ze wskaźników eutrofizacji jezior stwierdzono, że w analizowanym okresie wystąpił wzrost troficzności zbiornika Piaseczno.

The purpose of this work was to investigate the effects of Cr (III) and Cr (VI) compounds on the activity of acid and alkaline phosphatases in a Mollic gleysol and in Haplic Phaeozem soil samples. It was found that phosphatase activity in the soil decreases with increasing concentrations of Cr (III) in the range 2-20 g t-1. In the case of Cr (VI) an immediate reduction of both acid as alkaline phosphatase activity in relation to the control sample was also observed. Moreover, phosphatase activity has a tendency to diminish the deeper it is found in the soil profile. Soil phosphatase activity is also stimulated by the presence of organic matter.

The present study involved 180 slaughter turkey-hens of heavy Big-6 type divided into four groups (in triplicate repetition for 15 birds). All the birds were fed with the same standard full-dose mixtures in 5-stage system. The turkey-hens of groups I, II and III were given 1,2,4-triasole derivative (3-(2-pyridil)-4-phenyl-l,2,4-triasole-5-carboxylic acid), which has antibacterial, antifungal and immunomodulating properties, in amount of 50, 75 and 100 |ig per 1 dm3 of water. Group IV - control was given water without the additive. The 1,2,4-triasole derivative was given to drinking water, starting from the first day of bird's life and for the whole rearing period. The present results of biochemical analysis of blood plasma showed that addition of examined substance significantly reduced concentration of protein, glucose, triglycerides and uric acid as compared to control. It was stated that tested 1,2,4-triasole derivative elevated the level of HDL fraction percentage and alkaline phosphatase activity in blood plasma.
