Cadmium level in some tissues and organs from wild boar

The wild boar (Sus scrofa) is one of the most common species of Romanian wild game. It’s meat is found often on the market and in peoples menu list. One of the most dangerous heavy metals is cadmium. It has several toxic effects on: kidneys, liver, testes, bones [2, 5]. The study was carried out in three different areas regarding the contamination level with heavy metals: Forest District M., Forest District. C and Forest District S. Cadmium concentration was directly correlated with the pollution degree of the three different areas Forest District M. >Forest District C.> Forest District T. Cadmium concentration in wild boar tissues and organs was: in Forest District C. between 0.009 ppm and 0.341 ppm; in Forest District M. between 0.011 ppm and 5.346 ppm and in Forest District T. between 0.007 ppm and 0.123 ppm

Lead levels in soil-water-plant chain from a foresty ecosystem

Lead level was determined in soil (20 cm and 40 cm deep), water (water sources for wild game) and plants from three Forest Districts placed in areas with different degree of pollution. Determination of lead concentration was made in forestry ecosystem to see the impact of heavy metals (lead) on wildlife. In soil lead concentration was in limits at both depths (20cm and 40 cm) for all three Forest Districts, in water samples lead level exceeded the maximum admitted limit for drinking water (0.01 ppm) and for surface water (0.01 ppm) and from ecological point of view were in the Vth quality class. Lead concentration was under the maximum admitted limits for plants in all three Forest Districts

Aronia Melanocarpa Antioxidant Potential against Chromium VI Induced Morphological Changes in Endocrine Pancreas

AbstractHexavalent chromium is known as strong oxidizing agent, enters the cells easily and generates reactive oxygen species. It was demonstrated that Cr VI is toxic for liver, kidney, skin, nervous system, female and male reproductive systems. However, chromium effects on pancreas are less studied.Aronia melanocarpa fruits are rich in phenolic constituents: anthocyanins, procyanidins and phenolic acids, which demonstrated to have anti-oxidative, anti-viral, anti-mutagenic, anti-cancer, anti-inflammatory activities.Considering the aforesaid the present study was carried out in idea to see if Cr VI induces structural changes in pancreas, given it’s property of inducing ROS formation in cells, and if aronia extract can play a protective role.The study was carried out on white Wistar rats divided in 5 groups and exposed as follows: C - control -distilled water, Cr group - potassium dichromate, hexavalent chromium compound, in distilled water, 75 ppm for three months; CrA group - 75 ppm Cr VI + extract of A. melanocarpa for three months; Cr2 group - 75 ppm Cr VI for three months followed by one month of distilled water; CrA2 group 75 ppm Cr VI for three months followed by one month of extract of A. melanocarpa. At the end of exposure period pancreas was collected and prepared for histological analysis.Hexavalent chromium administration induced morphological and functional changes in endocrine pancreas cells. Microscopic examination of histological slides from pancreas revealed the size and number reduction of Langerhans islets and presence of degenerative lesions. Experimental group that received Cr VI combined with aqueous extract of Aronia presented almost normal architecture of endocrine cells, even more vascular changes occurred too, probably responsible for repairing phenomena

Traceability of food products and pharmaceutical products in relation to chemical investigation

Approaching issues related to the traceability of food and pharmaceutical products at the 26th International Symposium on Analytical and Environmental Problems, would like to point out the fact that the analytical chemistry investigations and their applications target both natural and processed products in the food and pharmaceutical industry (some raw materials being taken from the environment). In this context, the paper presents summary data on the traceability systems (integrated and differentiated). Thius, in order to highlight the scientific, technical and economic importance of traceability some data about the identification tools are summarized

Selenium in food and food supplements

The bioelements detected in the lithosphere and biosphere have aroused major interest in geology and biology. It was detected in minerals but also in tissues taken from plants, animals and humans. Among the bioelements, the natural distribution of selenium (Se) was studied, following the quantity in food, the structural specificity of the components. Along with these, the biological activity was studied, following its integration in food supplements
