“…As a result, Hg was present at the highest levels relative to the background, and this result is consistent with Marin Senila et al (2012) [55]. Calculation of NIPI values indicated that the northern piedmont is seriously polluted, with the pollution levels of individual river basins in the following order: Qingyang River > Yangyan River > Yukou River > E River.…”

We have measured the concentrations of toxic elements (Cd, Pb, As, and Hg) in 29 samples from agricultural soils in an iron ore mining area in the northern piedmont of Mount Wutai in Shanxi Province, China. The aim was to evaluate the potential health risks to local inhabitants based on the health risk assessment model derived from the United States Environmental Protection Agency (USEPA). The results show that the concentrations of the four heavy metals exceed their background values, especially in the case of Hg. The pollution level of the four heavy metals can be ordered as follows: Hg > Cd > Pb > As. The spatial distribution of the concentrations of the four heavy metals was uneven: pollution levels were lowest in the basin of the E River, and centered on the E River there was an increasing trend towards the Yukou River in the west and the Yangyan River in the east. In terms of the degree of pollution, this trend can be summarized as: Qingyang River > Yangyan River > Yukou River > E River. The main form of ingestion of the metals was via mouth and nose, and the risk to children is higher than for adults. Iron ore mining was the main cause of the increased concentrations of As and Cd, which represent a cancer risk for humans.

The objective of this study was to determine the chemical composition of five different food seeds (sunflower, poppy, hemp, flax and sesame) regarding fatty acid, mineral (Fe, Cu, Zn, Na, Mg, K, Ca, Al) and protein content. In addition, the total antioxidant capacity of the seeds was evaluated using the photochemiluminescent assay. The food seeds were subjected to lipid extraction and converted into fatty acid methyl esters before the gas chromatography analysis. In all food seeds, the saturated (SFAs), monounsaturated (MUFAs) and polyunsaturated fatty acids (PUFAs) were identified, respectively. PUFAs were the most abundant fatty acids (61.2% ± 0.07% and 84.8% ± 0.08% of total fatty acids), with the highest content in flax and hemp seed oil. Also, high amounts of omega-3 from PUFAs were determined in flax and hempseed oil. Based on the obtained results the sunflower, sesame and poppy seeds are good sources of omega-6, while flax and hemp seeds are good sources of omega-3. All samples are rich in minerals (Na, K, Ca, Mg) and have more than 20% protein content.

“…The toxicity is influenced both by total concentration and by availability of element [ 16 , 17 ]. Consequently, environmental regulations should include along the total elements thresholds, the evaluation of risk exposure to toxic elements in terms of their availability.…”

Mobilization of As from geological materials into ground and drinking water sources may represent an important threat to human health. The objective of this study was to assess the As concentration and availability in underground water used as drinking water sources. Water samples were collected from public and private wells in Timis-Bega area of Pannonian Basin, West Romania. Total-dissolved As measured after “classical” filtration of water samples was in the range of 0.10–168 μg L−1, thus exceeding the guideline value in majority of the samples. The aim of this study was also to assess the “truly dissolved” concentrations of As considered as available concentrations, in well waters, after passive sampling by Diffusive Gradients in Thin-films (DGT). The results showed that over 70% of total-dissolved As is in available forms. The obtained data were used to evaluate the risks of using the wells as drinking water source. Hazard quotients for ingestion and dermal pathways and hazard index (HI) for exposure to As were calculated. The HI values > 1 found that majority of samples indicated a health risk for local residents.
