An analysis of the concentrations of some mineral as potassium, sodium, calcium, magnesium and iron wasmade in the muscular tissue of the morocoto Piaractus brachypomus from the middle Orinoco River inVenezuela, captured in some flood lagoons with gillnet. The concentration of these minerals was analyzed byAtomic Absorption with flame of airacetyleneand correction of deuterium, using a team Perkin Elmer 3100coupled with an autosampler PerkinElmerACE51.An average of 45.32 ± 0.52 μg/g was determined in the ironconcentration, 3497.48 ± 107.06 μg/g in the concentration of calcium, 1528.95 ± 29.25 μg/g in theconcentration of magnesium, 3529.66 ± 65.24 μg/g in the concentration of sodium and 16488.90 ± 264.69 μg/gin the concentration of potassium. A variance analysis (ANOVA) and Duncan test later, demonstrated that theseconcentrations presented significant differences, with a bigger concentration of potassium, followed by thesodium and the calcium, and then the magnesium and the iron. Among these minerals the concentrations ofcalcium and potassium presented correlation statistically significant. The results constitute a contribution to theknowledge of the chemical composition of P. brachypomus, one of the freshwater fish most important in thecountry from the commercial point of view and in the aquaculture.

Proximate And Mineral Composition

The proximate and mineral analyses were conducted in the Department of Biochemistry Laboratory, Faculty of Basic Medical Sciences, Bayero University Kano, Nigeria, in May 2019. The study was carried out to determine the proximate and mineral composition of the fruit of Ficus polita using standard analytical methods. The fruit on dry weight basis (DW) contains moisture (9.12 %), ash (1.30 %), crude lipid (20.51 %), crude fibre (56.69 %), crude protein (1.19 %), available carbohydrates (11.40 %), and calorific value (234.98 Kcal/100 g). The fruit also contains potassium (324.46 mg/100 g), sodium (164.78 mg/100 g), calcium (91.09 mg/100 g), magnesium (70.06 mg/100 g), iron (3.39 mg/100 g), zinc (0.46 mg/100 g), manganese (0.37 mg/100 g), copper (0.23 mg/100 g), and cobalt (0.11 mg/100 g). The study revealed that F. polita fruit contains an appreciable amount of calorific value, crude fibre, crude lipid, available carbohydrate, and crude protein. The fruit was also found to be rich in minerals such as potassium, sodium, calcium, magnesium and iron. The fruit should be recommended as a good source of energy, fibre, lipid, carbohydrate, protein, potassium, sodium, calcium, magnesium, and iron.

The Town

The Dzhida ore field in the Zakamensk district of Buryatia features high concentration of mineralization within a small area. The Dzhida deposit is composed of complex ore. The ore field contains commercial-value primary deposits: Pervomai stockwork of molybdenum, Kholtoson tungsten lode and Inkur stockwork of tungsten. The Modonkul river catchment basin lies inside the Dzhida ore field. A real threat to the town of Zakamensk is created by manmade sand-bulk (old) tailings and slurry dump. By now, the concentrated flow of natural and man-made sand enters the low terrace and floodplain of the Modonkul river in the form of a talus train. This study is focused on the influence of the mine drainage effluent and the Inkur tributary on the water chemistry in the Modonkul river. 80 water samples were taken from the surface layer 0-0.5 m thick at five stations. Physicochemical indices of water were measured at the water sampling points, and the water chemistry was analyzed in a laboratory. In the background conditions, cations and anions in the Modonkul water chemistry range in decreasing order as follows: Са2+ > Mg2+ > Na++К+ и HCO - > SO 2- > Cl-. In the zone of mixture of natural and mine process water, the chemistry changes: from hydrocarbonate to sulfate (anion), from calcium-magnesium to sodium-calcium (cation). Downstream the natural chemistry changes to the hydrocabonate-sulfate composition, with prevailing content of calcium in cations. Iron content of water lowers 3-4 times after influx of mine effluents, while the contents of Mn, Zn, Co and Cd grow and then decrease downstream.

The aim of the study was to determine the basic chemical composition and mineral content in the sirloin and offal of fattener pigs, taking their sex into consideration. In addition, comparative analysis of the content of chemical and mineral components in the sirloin and offal was performed. The experimental material included 24 crossbred (Polish Landrace × Polish Large White) fatteners, from which samples of sirloin (musculus longissimus lumborum), liver, heart, and kidneys were collected for the analysis. A significant effect of the sex on the fat content in the sirloin and liver and on the level of magnesium (Mg), zinc, and iron (Fe) in the sirloin was demonstrated. Significant differences were found in the basic chemical composition and mineral content between the sirloin and the offal. In comparison with the liver, the sirloin contained lower amounts of protein and fat and higher potassium and Mg contents. In turn, the offal was shown to be a rich source of sodium, calcium, and trace elements (Fe, manganese, and copper). The mean cadmium concentration in the sirloin and offal was significantly lower than the threshold values for these elements, i.e., it accounted for 26% and 6.2% (liver)–19.5% (heart) of the allowable content of this element in pork meat and offal.

Abstract: The objective of this work was to characterize 'Cabernet Sauvignon' wines made from grapes cultivated in the region of Bagé, RS, Brazil, during three crop seasons. A randomized complete block design was carried out with three treatments and three replicates.The evaluations were performed for the 2004, 2007, and 2008 growing seasons. 'Cabernet Sauvignon' wines of the 2004, 2008, and 2009 harvests differed for the following parameters: density, alcoholic content, total acidity, pH, reducing sugars, OD 420, 520, and 620, color intensity, total anthocyanins, total polyphenols, sodium, calcium, magnesium, manganese, copper, iron, rubidium, phosphorus, methanol, propanol, 2-methyl-l-propanol, 2, 3 - methyl-l-butanol, and sum of alcohols. 'Cabernet Sauvignon' has potential to be produced in the Bagé region, and to help it to become a wine growing region in Brazil.
