The aim of this paper was to analyze the influence of microelements source and composition on the antioxidant activity of medicinal herbs. The microelements administered through salts, at NRC (Nutrient Requirements Council) level (A) increased significantly TACFRAP (total antioxidant capacity by FRAP method) for all groups of medicinal plants (a, b and c). The mineral salts and fritta improved TACFRAP in the first group (a – very high TACFRAP)

Codex Alimentarius Standard, EU Legislation and National Standards state honey authenticity. Authenticity in respect of production (to prevent adulteration) and authenticity in respect of geographical and botanical origin are the two main aspects of general honey authenticity. Quality of honey depends on the plant source, the chemical composition of these plants as well, as on the climatic conditions and soil mineral composition. Romanian acacia

This paper presents original studies about the influence of mineral and/or organic fertilization on the minerals contents (P, Na, K, Ca, Mg, Fe, Mn, Zn, Cu, Ni and Pb) in leguminous plants from permanent grassland situated in a hill area of Banat County. Determination of minerals in grassland is very important both for the nutritional or toxic effects of these elements and their compounds, in the plants, animals and environment. Phosphorous was analyzed

Background Copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) can pose serious threats to environmental health because they tend to bioaccumulate in terrestrial ecosystems. We investigated under field conditions the transfer of these heavy metals in a soil-plant-snail food chain in Banat area, Romania. The main goal of this paper was to assess the Roman snail (Helix pomatia) usefulness in environmental monitoring as bioindicator of heavy metal accumulation.

Background The goal of our study was to evaluate the effects of different medicinal herbs rich in polyphenol (Lemon balm, Sage, St. John’s wort and Small-flowered Willowherb) used as dietary supplements on bioaccumulation of some essential metals (Fe, Mn, Zn and Cu) in different chicken meats (liver, legs and breast). Results In different type of chicken meats (liver, legs and breast) from chickens fed with diets enriched in minerals and medicinal

Background: The aim of this study is to measure the levels of heavy metals (Fe, Mn, Zn, Cu, Ni, Cd and Pb) found in common vegetables (parsley, carrot, onion, lettuce, cucumber and green beans) grown in contaminated mining areas compared with those grown in reference clear area and to determine their potential detrimental effects via calculation of the daily metal intake (DImetal) and Target Hazard Quotients (THQ) for normal daily consumption of

It was analyzed the water content of three pollen samples from three different sources, using the classical chemical method (Karl Fischer). It is very important for this method to select the proper work conditions because pollen has a complex composition. For Karl Fischer
s method we selected the most adequate solvents, temperature and particle size. The Karl Fischer titration in a mixture of solvents (Hydranal
solvent and n-octanol) at high temperature
