“…Water is a natural resource essential for life in any ecosystem and must be of good quality because of the many services it offers (habitat for wildlife and human applications…). The development of human society since the late 19th century led to high levels of pollution in aquatic ecosystems due to agricultural, urban and industrial discharges [1]- [3] which in turn affected the quality of surface waters. These discharges affect the lives of aquatic biota [4]- [6].…”

The Nokoue Lake is the largest lake of Benin Republic and it is also considered as one of the most productive lagoon ecosystems in West Africa. This productivity is decreasing and thus raises productivity issue for a better management and conservation. Macroinvertebrate can be useful for this purpose. A study was conducted to assess the spatial variation of macroinvertebrates during high flood period. A total of 3892 macroinvertebrates of fresh and brackish water were sampled during the survey. Structural analysis of the macroinvertebrate community revealed that it was made up of 16 orders, 48 families and 66 genera dominated by Insecta compared to Mollusca, Crustacea and the Annelida. Insects were dominated by Diptera (Chironomus sp. and Tanytarsus sp.), Coleoptera (Dystiscidae) and accounted for 57.1% of the sampled population. Mollusca, Crustacea, Annelida and Arachnida were the following most abundant and represented 23.9%, 10.7%, 8.1% and 0.2% of the total population, respectively. The Evenness index of Pielou was higher on the Station 8 (0.91-0.97), close to Oueme River. However, no significant difference (p > 0.05) was observed neither between station nor between month on the Shannon-Wiener index (2.06-4.31), Simpson index (0.04-0.40) and the taxa number (10-27). Macroinvertebrate assemblages and composition were primarily due to changes in water quality dependent on hydroclimatic changes and probably to anthropogenic actions. This suggests the need for real investigation of the macroinvertebrate biological capacity when formulating conservation strategies for the Nokoue Lake.

“…While there are important natural sources of copper, multiple human activities (industries, agriculture, harbors) have considerably increased the input of this metal in estuarine and marine environments around the world (Flegal and Sanudo-Wilhelmy, 1993;van Geen and Luoma, 1999;Niencheski and Baumgarten, 2000;Morillo et al, 2005;Niencheski et al, 2006;D'Adamo et al, 2008). For example, in Patos Lagoon estuary (Southern Brazil), the largest coastal water body in South America, an increase of approximately 15-fold in copper concentration in water has been documented in the last 20 years (Seeliger and Knak, 1982;Baumgarten and Niencheski, 1998).…”

Acute toxicity, accumulation and tissue distribution of copper in the blue crab Callinectes sapidus acclimated to different salinities: In vivo and in vitro studies

et al. 2011

In vivo and in vitro studies were performed to evaluate acute toxicity, organ-specific distribution, and tissue accumulation of copper in Callinectes sapidus acclimated to two different experimental salinities (2 and 30 ppt). Blue crabs were quite tolerant to copper. Acute dissolved copper toxicity (96-h LC(50) and its corresponding 95% confident interval) was higher at salinity 2 ppt (5.3 (3.50-8.05) μM Cu) than at 30 ppt (53.0 (27.39-102.52) μM Cu). The difference between salinities can be completely explained based on the water chemistry because it disappeared when 96-h LC(50) values were expressed as the free Cu(2+) ion (3.1 (1.93-4.95) μM free Cu at 2 ppt versus 5.6 (2.33-13.37) μM free Cu at 30 ppt) or the Cu(2+) activity (1.4 (0.88-2.26) μM Cu activity at 2 ppt versus 1.7 (0.71-4.07) μM Cu activity at 30 ppt). The relationships between gill Cu burden and % mortality were very similar at 2 and 30 ppt, in accord with the Biotic Ligand Model. In vivo experiments showed that copper concentration in the hemolymph is not dependent on metal concentration in the surrounding medium at either experimental salinity. They also showed that copper flux into the gills is higher than into other tissues analyzed, and that anterior and posterior gills are similarly important sites of copper accumulation at both experimental salinities. In vitro experiments with isolated-perfused gills showed that there is a positive relationship between copper accumulation in this tissue and the metal concentration in the incubation media for both anterior and posterior gills. A similar result was observed at both low and high salinities. Furthermore, in vitro experiments showed that copper accumulation in posterior gills is also positively and strongly dependent on the incubation time with copper. Gill copper accumulation occurred at a lower rate in the first 2h of metal exposure, increasing markedly after this "steady-state" period. This finding was corroborated by a significant increase in copper influx to the gill perfusate (corresponding to crab hemolymph) after this time, measured using (64)Cu. In vivo, after uptake from solution, (64)Cu was primarily accumulated in the gills and the rest of the body rather than in the hemolymph, hepatopancreas, or other internal tissues. Overall, the present findings indicate that gills are a key target organ for copper accumulation, as well as an important biological barrier against the excessive uptake of copper into the hemolymph and the subsequent distribution of this metal to internal organs of the blue crab.

“…The totality of the planet's ecosystems is affected one way or another by the developments of human societies and the various waste rejections that could lead to high pollution levels in the coastal marine ecosystems (Smolders et al, 2003;Rao et al, 2007;D'Adamo et al, 2008). These waste rejections of urban, agricultural, and industrial origin alter communities and affect the organisms that compose them (Boening, 1999;Viaroli et al, 2005;Warwick, 2005).…”

The objective of this study is the evaluation of the resistance of the bioindicative species Patella rustica Linnaeus, 1758 (Gastropoda Patellidae) existing in the contrasted sites of the Algerian occidental seaboard through a follow-up of the seasonal variations of biometric indices. It is based on the analysis of biometric parameters of 600 individuals of this Gastropod mollusk from five sites: Madagh (MD), Bouzedjar Harbor (BH), Ain El Turck (AT), Oran Harbor (OH), and Kristel (KR). The seasonal sampling has been carried out and measurements on the height of the shell (H), its length (L), and its total weight (TW) are taken for all the populations of P. rustica. The correlation of the different measurements (length-height, length-total weight, height-total weight), with the help of the power curve and following STUDENT " t " test, DUNCAN, and the ACP, reveals the development of its shell first in height, followed in second position by the length, and this for the five sites under study. Weight would thus be the parameter under analysis that evolves the least quickly as compared to the other two biometric parameters involving a generally significant difference between the five sites under study. These results confirm that the growth of this mollusk varies depending on the seasons and relies on many biotic and abiotic factors that also condition the development of the shell and the growth of limpet. This approach represents a good means for environmental evaluation that could be used in biomonitoring programs to indicate the impact of pollution in the short and long term.
