—Nonpoint source pollution in the form of stormwater runoff is one of the most important emerging threats to ecosystems along the coastal margins of the United States. A wide diversity of potentially toxic chemicals is commonly found in stormwater. These include the various pesticides, petroleum hydrocarbons, heavy metals, and other common contaminants that originate from commercial, industrial...

Environmental pollution is a growing concern and, more importantly, pollution of the aquatic ecosystem is alarming. Bivalves are commonly used as bio-indicators of marine pollution. In the present study the Perna viridis was exposed to cadmium, copper, lead and zinc concentrations under longterm chronic toxicity for the estimation of biochemical biomarkers. Significant differences in TBARS leve...

oligochaeta worms are important organisms in aquatic ecosystem. their omnipresence makes them as an indicator of environmental changes and health of aquatic ecosystem. the members of the family tubificidae and in particular, genus limnodrilus are considered as the most tolerant oligochaets to aquatic pollution. therefore identification and biological characteristics of this taxon are of great h...

Snails (Mollusca : Gastropoda) are an ideal bio-indicators for palaeo-environments and water quality (pollution) and are much more useful in the classification of ecological diverse aquatic habitats.1-3 These aquatic snails also complete the life cycle of digenetic trematode parasites causing various dreaded trematodiasis diseases in vertebrates including men. Indeed these snails are an interme...

Pulp and paper mill, controversially, is one of the largest and major contributors of pollution in aquatic environment, affecting aquatic organisms in general and fishes in particular. Several field and laboratory studies were conducted worldwide on effects of both treated and untreated paper mill effluents on fish. The studies showed wide ranges of toxicity at organismal as well as at populati...

Fluoride in aquatic systems is increasing due to anthropogenic pollution, but little is known about how this fluoride affects organisms that live in and around aquatic habitats. Fluoride can bioaccumulate in structures comprised of calcium carbonate, such as shells and skeletons of both freshwater and saltwater species as diverse as snails, corals, and coccolithophorid algae. In this article, i...

Due to anthropogenic activities, heavy metals still represent a threat for various trophic levels. If aquatic animals are exposed to heavy metals we can obviously observe considerable toxicity. It is well known that an organism affected by cadmium (Cd) synthesize low molecular mass thiol compounds rich in cysteine (Cys), such as metallothioneins (MT) and glutathione (GSH/GSSG). The aim of this ...

Pharmaceuticals are beginning to receive attention as a source of pollution in aquatic environments. Yet the impact of physician prescription patterns on water resources is not often discussed in clinical decision making. Here, we comment on a case in which empiric antibiotic treatment might benefit a patient while simultaneously being detrimental to the aquatic environment. We first highlight ...

Riparian areas are critical interfaces between aquatic and terrestrial ecosystems. Protecting and enhancing them by implementing streamside management zones (SMZs) is an essential practice of sustainable forestry. SMZs provide ecological functions including protection against non-point source pollution, promotion of water infiltration, contribution of beneficial nutrients and coarse woody debri...
