The marine fish are extraordinarily nourishing food and are affluently accessible fish meat source. Fresh examined sample of grouper fish was collected from Mudasal odai fish landing center. The protein, carbohydrate, lipid, ash and moisture contents of Epinephelus coioides were found to be 19.07 mg, 4.03, 2.61, 77.38 mg and 1.21 mg/g respectively. The potassium and phosphorus are the predominant elements other nine components are present in considerable quantities in the total of 11 minerals. Palmitic acid, Oleic acid and Stearic acid were observed to be the major elements of total presented 15 fatty acids. In this current study we have concluded the grouper fish having rich source of protein and good fatty acids and it will facilitate to enhance the nutrition level on poor folks.

Biebrza National Park (BNP) in NE Poland is one of the least polluted regions of Europe and as such seems to be well suited for the determination of the composition of natural-background pollution of atmospheric dust. Samples of fallen dust were collected at monthly intervals between April 2003 and March 2004 in the isolated settlement of Grzędy. X-ray powder diffraction, scanning electron microscope images, and energy dispersive spectrometry revealed quartz, feldspars, micas, kaolinite, chlorite and hematite as major dust constituents. In addition, a few grains of Ni, Ni-Fe phosphide, and Fe-Ni-Cr oxides (probably of extraterrestrial origin) were observed. Anthropogenic constituents include amorphous aluminosilicates, barite, gypsum, Sn, Fe, Ti and Bi-W oxides. Quartz and feldspars constitute the majority of natural-dust pollution in BNP. Both grain size and mineral composition exhibit seasonal variations.

Our objective was to determine the content of macro- and micronutrients, toxic heavy metals as well as total phenols in 10 broccoli (Brassica oleracea var. italica) cultivars. The experiment was designed at the Poznań University of Life Sciences, Poland, and completed during two plant growing seasons. Broccoli seedlings were planted in a field in early July and the plants were harvested between September and October. The content of general forms of nitrogen was measured by distillation with the Kjeldahl method. The content of potassium, calcium and sodium was assessed by flame photometry, and the content of magnesium, cadmium, lead, nickel, copper, zinc, manganese and iron was determined by flame atomic absorption spectroscopy (FAAS). The content of heavy metals, macronutrients and sodium in the broccoli heads depended on a cultivar. Having analyzed the levels of macronutrients in ten broccoli cultivars, it was concluded that cv. Agassi and Tradition had the highest content of nitrogen and phosphorus. A very high amount of phosphorus was also found in cv. Beaumont. The highest concentrations of calcium and potassium were found in cv. Monte Carlo. The cultivars Agassi, Beaumont, Tiburon and Tradition were characterized by the highest content of magnesium. The highest content of sodium occurred in the cultivars Beaumont and Monopoly. With respect to micronutrients, the highest content of iron, copper, zinc and manganese was revealed in cv. Agassi. The highest content of nickel was determined in the cultivars Beaumont and Monte Carlo. In addition, the cultivar Monte Carlo was characterized by the highest content of lead, and Beaumont had the highest content of cadmium. However, the maximum permissible levels of cadmium and lead were not exceeded in the heads of the ten broccoli cultivars. In both years of the study, the highest content of phenols was found in cv. Steel and the lowest one appeared in cv. Agassi.

Zinc sorption was tested through four mineralogically diverse clay fractions of rendzina soils. The value and mechanisms of Zn sorption are strictly linked to the mineralogical composition of the clay fraction. Analysis of the variation of the buffer coefficient da/dCe, calculated according to the Freundlich isotherm, indicates that the fractions containing prevailing quantities of smectite, illite or kaolinite sorb Zn exchangeably (not specifically). Zn bonding in the smectite fraction is feeblest. The fraction containing opal CT adsorbs Zn permanently (specifically).

In 2004-2006, an experiment was established at the Experimental Station Rajkowo belonging to the Agricultural University (West Pomeranian University of Technology) in Szczecin. High blueberry bushes were planted in an alkaline reaction (pH 7.1) heavy soil using three different substrates. The bushes were planted in trenches filled with peat, cocoa husk and sawdust. The fertilization of the plants was limited to a sole nitrogen supply (30 kg N ha-1), because chemical analyses of both the soil and the substrates showed high and/or moderate content of other nutrients. In order to decrease cocoa husk reaction and to maintain the reaction of peat and sawdust, the bushes were irrigated with H2SO4 acidified water up to pH 2.5-3.5. The bed prepared of cocoa husk was characterized by the highest N (23.8 mg 100 g-1), Zn content (51.6 mg kg-1), and pH (5.0). On the other hand, sawdust substrate had the lowest salinity (0.35 g NaCl kg-1). Sawdust substrate showed the highest level of Mn (56.5 mg kg-1) and Cu (7.4 mg kg-1) and the lowest of Ca (83 mg 100 g-1), whereas, peat substrate showed the highest salinity (0.87 g NaCl kg-1) and the lowest pH (3.8). The usage of cocoa husk substrate resulted in the highest content of N (23.6), K (6.9 g kg-1) and Mn (104.5 mg kg-1) in cv. Sierra blueberry leaves as well as N (16.0) and K (6.5 g kg-1) in berries. The plants grown in sawdust substrate showed the highest level of Ca (1.75 g kg-1), Cu (3.2) and Zn (12.4 mg kg-1), in the leaves as well as S (1.7) and Cu (3.5 mg kg-1) in berries.

The aim of the experiments carried out in a high, polyethylene in the years 2004- -2006 was to examine the influence of the algae preparation Bio-algeen S-90 on yield, mineral composition of fruits, content of assimilatory pigments, intensity of assimilation and transpiration and photosynthetic water use efficiency index of the cherry tomato cv. Conchita F1. The results on tomato yields proved significant differences in total and marketable yield under the influence of Bio-algeen. The biggest total and marketable yields were obtained when plants were treated three times with Bio-algeen. Bio-algeen also caused increase in content of mineral components in cherry tomato fruits. Three- and fourfold sprays increased the content of total nitrogen, phosphorus, potassium, calcium, zinc, iron and nitrates. Treating tomato plants with the preparation increased the content of assimilatory pigments of tomato. Increase in a number of Bio-algeen sprays led to higher contents of total, a and b chlorophyll and carotenoids in leaves. Intensity of assimilation and transpiration of the plants and water use efficiency index depended on number of plants spraying with Bio-algeen. Plants sprayed two and three times with Bio-algeen were characterized by greater transpiration and assimilation intensity, but also by smaller efficiency of water use index.
