The aim of this study was to determine the content of selected heavy metals in birch sap, and to examine whether the tree diameter, the obtained daily sap volume and the date of collection have an impact on their content. Moreover, it was decided to check whether the tree diameter could affect the intensity of the sap leak. The study was carried out in central−eastern Poland, in the Garwolin Forest...

The aim of the study was to synthesize the latest literature data on the content of toxic elements in tissues of hunted animals and to determine whether there is a health risk associated with consumption of these products in the light of current legal regulations. The data show the increased mean lead contents in kidneys of wild boar (1.1900 mg/kg) and roe deer (0.9060 mg/kg) and in the muscle tissue...

The paper analysed Cd, Cr, Cu, Pb, Ni and Zn concentration in bottom sediments of fourteen retention reservoirs located in the Oborniki and Taczanów forest districts (western Poland). The sediments were collected in March and April 2018 from a surface layer with a thickness of 5 cm. Heavy metal determination was performed using inductively coupled plasma with mass detection (ICP−QQQ) method. The aim...

The paper presents results of the studies on Cu, Mn and Zn content in forest soils of northern and central Poland covered by intensive monitoring. The investigated stands (Białowieża, Chojnów, Gdańsk, Krotoszyn, Krucz, Łąck, Strzałowo, Suwałki) cover various soil reference groups, including Brunic Arenosols, Cambisols and Stagnosols, developed from Quaternary deposits of different origin – glacial...

The development of industry, intensive agriculture and the automotive industry has contributed to a massive increase in pollution of the environment. The many pollutants accumulating in the environment include toxic elements (Hg, Zn, Cu, Pb, As, Cd) whose natural content in soil and the atmosphere is very small. Honeybees (Apis mellifera L.) are entirely dependent on flowering plants that provide...

Wykorzystanie osadu ściekowego do użyźniania gleby na plantacjach roślin energetycznych wydaje się być najbardziej racjonalną metodą jego użycia. Obok cennych składników biogennych, takich jak N, P, Mg czy K, osad ściekowy w swoim składzie zawiera także substancje toksyczne i szkodliwe. Obecność metali ciężkich w niektórych osadach stanowi czynnik ograniczający ich wykorzystanie w rolnictwie. Wierzba...
