| Conventional nebulisation ICPMS (Inductively Coupled Plasma Mass Spectrometry), was used to determine the concentration of a broad range of elements in the salmon louse Lepeophtheirus salmonis. Lice samples were collected from Atlantic salmon in seven localities (4 fish farms and 3 wild salmon fisheries) on two separate sampling occasions and prepared for analysis. Sixty six elements were measured, 35 of these were found to be variable and were subjected to univariate and multivariate statistical analysis. The results of the single element comparisons showed that not all individual sites could be discriminated from each other. Sea lice collected from cultured salmonids could be discriminated from those on wild salmonids at the same site using the elements... |

| ABSTRACT Vermicomposted vegetal and animal residues are rich in nutrients and humic substances and thus can be applied to the soil as a source of functionalized organic matter (OM) and as an alternative to chemical fertilizers. In Southern Brazil, many animal and vegetal residues are easily accessible. Therefore, this study aimed to evaluate alterations in soil chemical properties and OM chemical composition in response to the application of local vermicomposted residues. The vermicomposts of: cattle manure (CM), sheep manure (SM), rice parboiling sludge (PS), CM+PS; SM+PS; CM+food waste (FW); SM+FW; CM+fruit waste (FRW); and SM+FRW were mixed with Acrisol (Argissolo) samples collected at 0.00-0.20 m layer, and the samples were incubated in plastic bags... |

| At the present time there has been a serious question of non-renewable energy resources substitution that is why solved problem has worldwide meaning within high increase of fuels consumption from renewable energy resources. The aim of this paper is definition of other possibilities and limits for energetic utilization of solid biomass modified by pyrolysis technology to biochar. Analyzed samples are processed into the form of pellets in diameter 8 mm made from rape straw. There is used laboratory pyrolysis unit working on the principle of slow pyrolysis reaction which processes samples at the temperature of 400 °C and taking 220 minutes in reactor filled by nitrogen medium. The experimental part of the work is based on elemental and stoichiometric... |
