“…Moreover, metals in sediments and in organisms with a long life cycle, as fish, usually reflect trends of their content in whole aquatic ecosystems and water catchment area of many years and appear to be weakly related with their content in water (Gladyshev et al 2001). This has strong implications for monitoring programmes (Ion et al 1997). In this respect, when planning monitoring programmes for As, it is important to remind that biomagnification does not occur; rather, As concentrations decrease as trophic level increases (Culioli et al 2009b).…”

Arsenic (As) may occur in surface freshwater ecosystems as a consequence of both natural contamination and anthropogenic activities. In this paper, As concentrations in muscle samples of 10 fish species, sediments and surface water from three naturally contaminated rivers in a central region of Argentina are reported. The study area is one of the largest regions in the world with high As concentrations in groundwater. However, information of As in freshwater ecosystems and associated biota is scarce. An extensive spatial variability of As concentrations in water and sediments of sampled ecosystems was observed. Geochemical indices indicated that sediments ranged from mostly unpolluted to strongly polluted. The concentration of As in sediments averaged 6.58 μg/g ranging from 0.23 to 59.53 μg/g. Arsenic in sediments barely followed (r = 0.361; p = 0.118) the level of contamination of water. All rivers showed high concentrations of As in surface waters, ranging from 55 to 195 μg/L. The average concentration of As in fish was 1.76 μg/g. The level of contamination with As differed significantly between species. Moreover, the level of bioaccumulation of As in fish species related to the concentration of As in water and sediments also differed between species. Whilst some fish species seemed to be able to regulate the uptake of this metalloid, the concentration of As in the large catfish Rhamdia quelen mostly followed the concentration of As in abiotic compartments. The erratic pattern of As concentrations in fish and sediments regardless of the invariable high levels in surface waters suggests the existence of complex biogeochemical processes behind the distribution patterns of As in these naturally contaminated ecosystems.

“…A research study from Kwanetal et al (2003) further suggests along with a statement by Ion et al (1997) that mussels could provide stronger signals than adult fish to evaluate areal pattern of contamination in the flora and fauna of a river system. However, these studies refer to the aquatic system of the lower St. Lawrence River [71,72].…”

This review paper aims to address the topic of the living, prospects as well as jeopardies of the invasive Zebra Mussel. Broad literature reviews have been taken place to gather as many facts on this species as possible to summon all the most significant information up in one paper to be available for everyone. To get a better understanding of freshwater mussels in general, a short review of freshwater mussel diversity in America has been written also. The review paper focuses especially on living, prospects, and jeopardies in North America. The review revealed, freshwater mussels to be of practical importance and of great primeness for scientific research due to their unique life cycle. Especially the freshwater mollusk Dreissena polymorpha (Dreissenidae), colloquial known as the zebra mussel draws interest due to the mollusks’ invasive character and their tremendous filtering capacity. Once originated from the Ponto-Caspian region and currently present in 33 European Countries and 33 states of North America the freshwater bivalve draws interest all over the world. Their larval stage allows broad invasions of aquatic systems. Even though they can both harm their habitat as well as other organisms living in it, Dreissena polymorpha enormous filtering capacity can be utilized effectively if managed right. However, a lack of natural enemies and environmentally friendly pesticides makes control of Dreissena polymorpha in open water impossible.

The Massena (New York) and Cornwall (Ontario) region has a long history of Hg discharge into the St. Lawrence River. The objectives of this study were to evaluate if Hg levels have declined in this portion of the river since 1975 and to compare Hg level in fish species upstream and downstream of this area in order to evaluate the anthropogenic contribution to Hg levels in fish. Mercury levels in four fish species were monitored over a 20-year period (1975-1995). A general linear model and an analysis of covariance were used to extract temporal trends and spatial variability, respectively, while correcting the data for fish length. Over time, Hg levels declined in most fish species. In the four regions studied, Hg levels in fish were similar, which suggests that other sources like atmospheric deposition and Hg loading from the Great Lakes may also contribute to the Hg burden in fish in the St. Lawrence River. This indicates that fish, with large home range, are good biomonitors of temporal Hg releases but their ability to avoid point sources makes them less appealing as biomonitors to address spatial variability in Hg releases.
