Article Synopsis
  • Rose petals contain beneficial phenolic compounds like anthocyanins, which are linked to health benefits due to their antioxidant properties.
  • Eighteen rose cultivars were analyzed for their total polyphenol, flavonoid content, and antioxidant activity, revealing significant variation among them, with the highest anthocyanin content identified using advanced chromatography techniques.
  • The study found that anthocyanin levels were positively correlated with antioxidant activity, and specific cultivars demonstrated both cytotoxic effects on melanoma cells and enhanced proliferation of normal skin cells.

Article Synopsis
  • This study investigates heavy metal contamination in agricultural soils of the Baia Mare region, Romania, focusing on nickel, cadmium, zinc, lead, and copper in a sheep-based food chain.
  • Analysis using ICP-MS showed that copper and zinc levels exceeded safe limits near mining sites, with high lead and cadmium concentrations near industrial areas, raising health concerns.
  • The research highlights the need for ongoing monitoring and risk assessment to protect public health from contaminated dairy products resulting from heavy metal bioaccumulation in the food chain.

We investigated the mineral concentrations of 61 honey samples from eight Romanian regions, employing advanced techniques to assess 30 chemical elements. Potassium emerged as the dominant element, showcasing significant variations across geographical locations. Essential minerals like calcium, magnesium, sodium, and manganese maintained consistent levels, while zinc, copper, and chromium were present in smaller proportions.

The study examined soil and honey samples from the Maramureș region, assessing potentially toxic elements and their concentrations. The highest concentrations were found for (Cu), (Zn), (Pb), (Cr), (Ni), (Cd), (Co), and (As), while (Hg) remained below the detection limit. Samples near anthropogenic sources displayed elevated metal levels, with the Aurul settling pond and Herja mine being major contamination sources.

The purpose of this study was to evaluate the environmental quality of polluted areas near the Baia Mare Mining and Smelting Complex for future improvements the quality of the environment in polluted areas, such as the city of Baia Mare and its surroundings. Samples of soil and organs of grapevine () were collected from Baia Mare, Baia Sprie and surrounding areas (Simleul Silvaniei) and their content of Cu, Zn, Pb, Cd, Ni, Co, As, Cr, Hg were analyzed. Most soil and plant samples showed higher metal concentrations in Baia Mare and Baia Sprie areas compared to Simleul Silvaniei, exceeding the normal values.

Background: The determination of micro-, macroelements and heavy metals in the soil-grapevine-wine system is extremely important for the wine industry, the grape and wine quality, and also for consumer health. The quantitative analysis of 10 elements: Na, Ca, Mg, Fe, Cu, Zn, Pb, Cd, Ni, Co were made in soil at different depths and also in grapevines (leaves and canes). For grape juice and wine there were analyzed the concentrations of Cu, Zn, Pb, Ni and Cd on three cultivars Fetească albă, Fetească regală and Riesling italian, located in Turulung vineyard, NW Romania.
