Concentration of Heavy Metals in the Biot of Lake Radoniqi and Badovci, Food Safety: Study of the Natural Environment in the Republic of Kosovo

Abstract

The purpose of this research is to determine the content of heavy metals in the lakes of Kosovo, lakes with heavy metals such as: (Hg, Cd, Pb, As, Fe, Zn, Ni, Cu), in water and water sediment in Lake Radoniq and Lake Badovc. Determination of heavy metals (Pb, Cd, Hg, As), in muscle tissue and fish organs. Parameters as an indicator of fish safety for food, indicator of environmental pollution (Kosovo lake bioten). Age of fish, the amount of fat are important factors that affect the accumulation of heavy metals in fish. This indicates that the bioaccumulation of heavy metals is a special process and indicates the concentration of heavy metals in the body of the fish. The high concentration of Fe in fish organs is of particular importance for hemoglobin and its role in fish. Metal indicators such as biocumulation factors are different, for example, for Pb can be increased with high concentrations compared to international parameters which depends on the species of fish and the location of catching s137 fish, the concentration of heavy metals in the Lake and the impacts from agricultural activities. The concentration of heavy metals in the body of aquatic life depends on the way in which heavy metals penetrate, giving the body the opportunity to detoxify them through metabolism. Metabolism means the exchange of substances, the uninterrupted exchange of matter between the living organism and the external environment. This process is the basis of life, which allows a cell to grow and reproduce, maintain its structure and respond to its environment.

Research of Some Varieties of Spring Barley (<i>Hordeum vulgare</i>), EU Region, Redimenets in the Agroecological Conditions of Kosovo

“…The soil where the research testing of barley cultivars was done in Peja is reddish brown, while the smonica type soil in Pestovë, which represents almost 25% of Kosovo's soil. In terms of chemical content, based on analyzes performed for research purposes, both field test plots have approximate values,this research presents the findings of the study including the analysis and interpretation of the analyzed data (Dreshaj et al 2021).…”

“…The soil analysis showed that the two researched soils were rich in medium humus, phosphorus, potash, rich in calcium and magnesium, bioaccumulation can be due to bioconcentration (absorption from the food chain), or biomagnification (Dreshaj et al 2021). Based on these data, the doses of nitrogen, phosphorus and potash fertilization were determined, while there was no need for calcium and magnesium fertilization.…”

Analysis and Influence of Barley Protein Content for Beer Production in Kosovo

“…The most important source of cadmium in the air is industrial plants. Other sources of anthropogenic origin include phosphate fertilizers (Dreshaj et al, 2021).…”
