| The Water European Framework Directive requires the implementation of programs to monitor the chemical quality of water bodies (freshwater, transition water and seawater), based on grab measurements of concentrations of various contaminants (metals, organic compounds). The results are limited by several analytical difficulties, and the poor representativity because of the temporal variability of contamination. The passive sampling techniques, which basically consist of concentrating substances on a submerged device for a given period, and analyzing accumulated substances, should improve the monitoring, by simplifying analytical issues (lower detection limits, analysis in a simpler matrix), and allowing time integration of the contamination. Here, we... |

| We look to a particular social-ecological system, the restoration community in Rhode Island, USA and the rivers, wetlands, marshes, and estuaries they work to protect, to draw connections between communication, community involvement, and ecological restoration project success. Offering real-world examples drawn from interviews with 27 local, state, federal, and nonprofit restoration managers, we synthesize the mechanisms that managers found effective to argue that the communication employed by resource managers in each phase of the restoration process, in prioritization, implementation, and monitoring, and for garnering broad-based support, shapes the quality of public engagement in natural resources management, which, in turn, can impact the stakeholder,... |

| O Manual para gestão da água e de resíduos do processamento de peixes é uma publicação técnica que aborda de forma organizada e didática duas questões fundamentais para gestão das indústrias de processamento de pescados nos tempos atuais: consumo de água e geração de resíduos. Para isso, reunimos uma equipe multidisciplinar com conhecimento em legislação, produção e sanidade de peixes, processamento de alimentos, melhoria de processos industriais, microbiologia, economia e estatística. Esse contexto ganha relevância diante da frequência com que diversas regiões no planeta têm sofrido com a escassez de água e com a contaminação química e orgânica dos corpos hídricos, em razão do descarte incorreto de resíduos e efluentes gerados nas indústrias. O foco no... |

| Efficient allocation of water requires knowledge of water's value in both consumptive and nonconsumptive uses. This study estimates the marginal value of water in lake recreational and aesthetic (RA) use. An hedonic price equation (employing the Box-Cox functional form) indicates lake front location, distance to lake, and scenic view are significant RA characteristics of housing. Water front properties command a premium price for the private access they offer. Beyond the water front, the marginal RA price falls rapidly with increasing distance, becoming asymptotic to some minimum. Twenty-two percent of housing price is found to be attributable to the RA component. |

| Rigorous control of water quality in hemodialysis services is extremely important in order to guarantee a better quality of life of the patients submitted to this treatment. The lack of adequate water monitoring has caused the death of various patients in the past. The objective of the present study was to determine the physicochemical and bacteriological characteristics of water used by hemodialysis services in hospitals of the city of São Luís, Maranhão, Brazil. Bacteriological analyses included the membrane filter method for the determination of total coliform bacteria, the Cult-Dipcombi-TTC-agar method for heterotrophic bacteria and the limulus amebocyte lysate method for the determination of endotoxins. Eighteen water samples obtained from three... |

| Water used in hydrotherapy units of Nova Iguaçu and Nilópolis, Rio de Janeiro State, Brazil, was microbiologically analyzed. Thirty samples (5ml each) were weekly collected from September 2001 to June 2002 before the beginning and after the end of activities in the units. For analysis, routine techniques were used, which showed the presence of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella spp, Candida spp, Penicillium spp, Epidermophyton spp, Aspergillus fumigatus, Aspergillus niger, Aspergillus spp, Cephalosporium spp, Cladosporium spp, Trichophyton rubrum, and Trichophyton spp. Results indicated a need for improving hygienic conditions, suggesting that water might be a contamination source in the evaluated units. |

| The present study evaluated the microbiological water quality and tissue lesions in gills from Nile tilapia (Oreochromis niloticus) and hybrid tambacu (Colossoma macropomum female x Piaractus mesopotamicus male). For this, water and gills were collected from fish farming at six locations in Itapecuru-Mirim County, Maranhão State. Microbiological water analyses revealed contamination by total coliforms, Escherichia coli and heterotrophic bacteria. In the gills, we observed a diversity of Gram-positive and Gram-negative bacteria. The tissue lesions were: lamellar fusion, interlamellar hyperplasia, sub-epithelial edema and telangiectasia. Inflammatory lesions were not observed. Significant statistical difference (p > 0.05) was not detected when... |

| Within the natural sciences, it has long been recognized that biological activity can modify the texture, structure and composition of surface sediments. Darwin (1881) already examined the stirring of soils by burrowing earthworms and made detailed observations on how these organisms affect soil processes. A similar phenomenon can be observed in aquatic sediments, which are inhabited by a diverse biological community, supported by the flux of organic matter and oxygen from the overlying water column. Surface sediments of oceans, estuaries, lakes and rivers are highly active biogeochemical environments and an effective way to generate insight in the complexity of the interactions is by means of so-called general early diagenetic models (e.g. Soetaert et al,... |
