This study aimed to evaluate the nutritional value (proximate, fatty acid profiles, vitamins and mineral contents and also nutritional quality indices (NQI)) of grass carp (Ctenopharyngodon idella) prepared according to common consumer techniques: raw, poached, steamed, microwaved, pan-fried and deep-fried (in olive oil). In comparison to raw fish fillets, when grass carp was cooked there was a...

abstractbackground and objectives: considering progressive growth of industry and technology, the accumulation of environmental contaminants, especially heavy metals (hms) in the soil is of increasing worldwide concern about the probable soil pollution risks. the perception of pollutants spatial distribution pattern and recognition of factors which control this pattern and identification of pro...

Elevated inorganic phosphate (Pi) concentrations in pore water of amended tailings under direct revegetation may cause toxicity in some native woody species but not native forbs or herb species, all of which are key constituents in target native plant communities for phytostabilizing base metal mine tailings. As a result, Pi sorption capacity has been quantified by a conventional batch procedur...

The study compares nitric acid and ethylenediaminetetraacetic acid (EDTA) extraction of forest soils for the analysis of trace metals Fe, Mn, Zn, Cu, Pb, and Cd. Fifty forest soil samples from ten different locations were extracted using both methods. The two extraction procedures were compared through regression analysis for each element. All elements were analysed by flame atomic absorption s...

to determine the extent and the size of the environment pollution with heavy metals, biologicalmethods, investigating the enzymatic activity of soil can be applied. most frequently, the enzymes investigated in the soils threatened with anthropogenic contamination are phosphatases, dehydrogenases as reacting fastest to the increase in the content of heavy metals in the environment. the aim of th...

Abstract The immobilization effect of soil amendments on leaching and bioavailability Pb, Zn Cd in highly contaminated soils under industrial impact was studied by collecting the surroundings Zn-Pb Smelter “Miasteczko Śląskie” southern Poland as an example. Various amounts four additives (phosphate fertilizer, limestone powder, bentonite rock bog iron ore) were tested laboratory experiments to ...

the role played by soil constituents in governing temporal trends of metal mobility in calcareousmediterranean soils deserves special attention due to the particular soil and climate characteristics. reactionsoccurring during the aging modify the metal mobility over time, and the rate of metal application and type ofsoil can be decisive in the outcome of aging reactions in soils. the aim of the...
