“…High concentrations of this heavy metal were detected in some aquatic ecosystems collecting vineyard runoff water and it is also highly concentrated in ground water (Gerbe 1996, Teisseire 1999). There are also anthropogenic sources of environmental contamination by copper including mining, smelting, foundries, municipal waste incinerators, burning of coal for power generation and a variety of copper-based products used in building and construction (Nor 1987, WHO 1998.…”

Nile tilapia, Oreochromis niloticus, of both sexes were reared in freshwater and exposed to 0.5, 1.0 and 2.5mg L-1 of waterborne copper for a period of 21 days. Liver and gill samples were collected after 21 days of exposure to copper and lesions were analyzed by light microscopy. The main histopathological changes observed in gills exposed to the highest concentration were edema, lifting of lamellar epithelia and an intense vasodilatation of the lamellar vascular axis. Although less frequent, lamellar fusion caused by the filamentar epithelium proliferation and some lamellar aneurisms were also found. The liver of control group exhibited a quite normal architecture, while the fish exposed to copper showed vacuolation and necrosis. These hepatic alterations were more evident in fish exposed to 1.0 and 2.5mg L-1 copper concentrations. The number of hepatocytes nucleus per mm² of hepatic tissue decreased with the increase of copper concentration. In contrast, the hepatic somatic index was high in fish exposed at 2.5mg L-1 of copper. In short, this work advance new knowledge as influence of copper in the gill and liver histology of O. niloticus and demonstrated that their effects could be observed at different concentrations.

“…It is present in concentrations less than 5 g/L in natural aquatic environments (EIFAC, 1976). Pesticide application is of particular interest among different sources of copper pollution such as mining, industrial discharge, sewage sludge disposal, and fertilizers (Nor, 1987). Copper sulfate (CuSO ) is one of the most widely used algicides for the control of phytoplankton in fish ponds, reservoirs, and lakes, as well as a herbicide used in aquatic weed control (Effler et al, 1980, Carbonell andTarazona, 1993).…”

“…However at higher concentrations free cupric ions have been indicated as the most toxic forms of Cu present in the aquatic environment for marine organisms (Nor 1987), as they are supposed to damage intracellular proteins which lead towards apoptotic cell death (Monteiro et al 2009). Other studies (USEPA 1985;James et al 2008;Jorge et al 2013) revealed a strong correlation between the concentration of Cu in the water body and physiological changes such as a lag in growth in the organisms they studied.…”

Estuaries and coastal zones are dynamic transitional systems which provide many economic and ecological benefits to humans, but also are an ideal habitat for other organisms as well. These areas are becoming contaminated by various anthropogenic activities due to a quick economic growth and urbanization. This chapter explores the sources, chemical speciation, sediment accumulation and removal mechanisms of the harmful elements in estuarine and coastal seawaters. It also describes the effects of toxic elements on aquatic flora and fauna. Finally, the toxic element pollution of the Venice Lagoon, a transitional water body located in the northeastern part of Italy, is discussed as a case study, by presenting the procedures adopted to measure the extent of the pollution, the impacts on organisms and the restoration activities.
