Blood clinical-chemical parameters (BCCPs) are used to investigate physiological consequences attributed to exposure to anthropogenic stressors, such as exposure to Tris(1,3-dichloro-2-propyl) phosphate (TDCIPP) and Dechlorane Plus (DP), which are flame retardants (FRs), on avian health. Japanese quail (Coturnix japonica) were used as a model species to investigate individual and mixture effects of both FRs by injecting different concentrations (5, 50, or 500 ng/µL) of either of these compounds as well as a 1:1 mixture of both into fertilized eggs. To estimate post-hatching effects, 18 BCCPs were evaluated from 101 chicks at day 14. Albumin levels were found to be significantly elevated in the groups exposed to high doses of TDCIPP alone as well as a mixture of TDCIPP and DP. However, during the course of the study, the initial corn-based feed had to be substituted by a fishmeal-based feed. The 8 days consuming the new feed played a significant role on 12 of 18 BCCPs measured. Consequently, it is recommended that dietary habits need to be considered when investigating the physiological impact of contaminants using BCCPs as biomarkers in growing nestlings both in controlled in vivo and field experiments. 相似文献

Biochemical constituents and master elements (Pb, Cr, Cd, Fe, Cu, Zn, Hg, B, Al, SO4 2?, Na, K, Li, Ca, Mg, and F) were investigated in six different seaweed species from Abu Qir Bay in the Egyptian Mediterranean Sea coast. The moisture level ranged from 30.26% in Corallina mediterranea to 77.57% in Padina boryana. On dry weight basis, the ash contents varied from 25.53% in Jania rubens to 88.84% in Sargassum wightii. The protein contents fluctuated from 8.26% in S. wightii to 28.01% in J. rubens. Enteromorpha linza showed the highest lipids (4.66%) and carbohydrate contents (78.95%), whereas C. mediterranea had the lowest lipid (0.5%), and carbohydrate contents (38.12%). Chlorophylls and carotenoid contents varied among the species. Total antioxidant capacity of the tested green seaweeds had the highest activities followed by brown and red seaweeds which had a similar trend of phenol and tannins contents. High reducing power was observed in all tested seaweeds extract except Ulva lactuca. Brown species had the highest amount of elements followed by red and green seaweeds. Notably, SO4 2? recorded the highest level in the tested green species (108.05 mg/g dry weight (DW)). The Ca/Mg and K/Na ratios reflected highly significant difference between seaweed species. This study keeps an eye on 29 parameters and by applying stepwise multiple regression analysis, prospective equations have been set to describe the interactions between these parameters inside seaweeds. Accordingly, the tested seaweeds can be recommended as a source of healthy food with suitable ion quotient and estimated daily intake values. 相似文献

In the present study, we investigated the effects of two bulking materials, Sphagnum peat and pine wood chips, on the early stages of biowaste composting in two pilot-scale processes. Emphasis was placed on studying the formation conditions of malodorous compost gases in the initial phases of the processes. The results showed that gas emission leaving an open windrow and a closed drum composting system contained elevated concentrations of fermentative microbial metabolites when acid Sphagnum peat (pH 3.2) was used as a bulking material. Moreover, the gas emission of the peat amended drum composter contained a high concentration of odour (up to 450,000 ou m?3 of air). The highest odour values in the outlet gas of peat amended composts coincided with the elevated concentrations of volatile organic compounds such as acetoin and buthanedion. We conclude that the acidifying qualities of composting substrates or bulking material may intensify odour emission from biowaste composts and prolong the early stages of the composting process. 相似文献

In this article, focusing on the ongoing implementation of the EU Water Framework Directive, we analyze some of the opportunities
and challenges for a sustainable governance of water resources from an ecosystem management perspective. In the face of uncertainty
and change, the ecosystem approach as a holistic and integrated management framework is increasingly recognized. The ongoing
implementation of the Water Framework Directive (WFD) could be viewed as a reorganization phase in the process of change in
institutional arrangements and ecosystems. In this case study from the Northern Baltic Sea River Basin District, Sweden, we
focus in particular on data and information management from a multi-level governance perspective from the local stakeholder
to the River Basin level. We apply a document analysis, hydrological mapping, and GIS models to analyze some of the institutional
framework created for the implementation of the WFD. The study underlines the importance of institutional arrangements that
can handle variability of local situations and trade-offs between solutions and priorities on different hierarchical levels. 相似文献
