Submitted 11 Jan 2017; Accepted 6 Feb 2017; Published 13 Feb 2017 Extended-spectrum β-lactamase (ESBL)-producing Enterobacteria has become a considerable global concern because of their potential dissemination in humans, in domestic animals, wildlife and the environment. The present study aimed to explore the ESBL producing enterobacteria in aquatic sources of Bangladesh as the water may be the...

Inland and transitional aquatic systems play an important role in global carbon (C) cycling. Yet, the C dynamics of wetlands and floodplains are poorly defined and field data is scarce. Air-water CO2 fluxes in the wetlands of Doñana Natural Area (SW Spain) were examined by measuring alkalinity, pH and other physiochemical parameters in a range of water bodies during 2010-2011. Areal fluxes were...

Tidal marshes provide nursery habitats for many commercial nektonic species; thus, determining trophic linkages between tidal marshes and aquatic consumers is important for sustaining fishery production in estuarine ecosystems. We examined stable isotopes (δ13C, δ15N) in 4 commercial nekton species (Chelon haematocheilus, Synechogobius ommaturus, Lateolabrax maculatus and Exopalaemon carinicaud...

Aquatic hyphomycetes are a group of freshwater fungi that includes asexual stages of ascomycetes and basidiomycetes. Even though aquatic hyphomycetes are a phyllogenetically heterogeneous group, there are common characteristics to most species: (i) they are saprotrophs, using submerged leaves and wood as substrates and sources of carbon (Gulis et al. 2006b), (ii) they can obtain nutrients from ...

Aquatic foods such as fish, shrimp, and shellfish are important human nutrient sources. However, aquatic spoil quickly during processing storage due to spoilage bacteria endogenous enzymes. Ultra-high-pressure (UHP) technology, an advanced non-thermal treatment method, is effective preservation technique for foods. The mechanism of UHP technology destroy non-covalent bonds by UHP, which l...

his fact sheet provides a summary of a review by the CCME Soil Quality Guidelines Task Group (SQGTG) of the implications of propylene glycol (PG) releases to Canadian soil environments. Following a review of the releases, fate and effects of PG in soils, the SQGTG opted not to develop Canadian soil quality guidelines at this time. Nonetheless, releases of PG to the environment can pose serious ...

A program to develop instructional materials for implementing marine and aquatic education in Ohio middle schools was begun by Ohio Sea Grant in 1977. This was followed 3 years later by a grant to disseminate the materials to schools in Ohio. To determine the effectiveness of the dissemination process a baseline study was conducted in the autumn of 1980. The survey obtained information on attit...

There have been increasing human health and ecological concerns about ionic perchlorate (ClO4-) since it was detected in drinking water sources in 1997. Perchlorate is known to affect thyroid function, causing subsequent hormone disruption and potential perturbations of metabolic activities. According to current estimates, perchlorate is found in the surface of groundwater of 14 states, includi...
