“…Indeed, it has been shown that increased tolerance to metals can be rapidly induced in the laboratory by pre-exposure to sublethal concentrations (e.g., Stuhlbacher and Maltby (1992) for Cd in G. pulex; Khan et al (1988) in Palaemonetes pugi); and that conversely, it can be rapidly lost after transplantation from contaminated environments to laboratory clean conditions (e.g., Maltby and Crane (1994) in G. pulex; Klerks and Lentz (1998) in the fish Gambusia affinis). These authors suggest that in such situation the increased tolerance is temporary, and is likely to be a consequence of physiological acclimation rather than genetic adaptation.…”

Deciphering evolutionary processes occurring within long-term contaminated wild populations is essential for the ecological risk assessment of persistent chemical contaminations. Using field populations of Gammarus, a commonly-used genus in aquatic ecotoxicology, the present study sought to gain insights into the extent to which long-term exposure to metals in the field could effectively lead to shifts in toxicological sensitivities. For this, we identified a Gammarus population inhabiting a stream contaminated by cadmium (Cd). We compared the Cd-exposure and Cd-sensitivity of this population to those of five reference populations. Active biomonitoring determined in different years and seasons that significant levels of Cd were bioavailable in the contaminated site. Laboratory sensitivity tests under common garden conditions established that this long-term field exposure led to the development of a moderate Cd tolerance, which was maintained after a 3-week acclimatization in the laboratory, and transmitted to offspring produced under clean conditions. The potential physiological costs of tolerance were assessed by means of feeding rate measurements (in the laboratory and in situ). They revealed that, unlike for reference populations, the feeding activity of organisms from the tolerant population was greatly decreased when they were maintained under laboratory conditions, potentially indicating a high population vulnerability to environmental perturbations. Because dissolved Cd concentrations in water from the contaminated site were low (averaging 0.045 µg L(-1)) and below the current European environmental quality standard for Cd for inland surface waters (fixed at 0.08 µg L(-1) in soft water environments), this case study sheds light onto the extent to which current environmental quality standards are protective against potential adverse outcomes of adaptive and micro-evolutionary processes occurring in contaminated environments.

“…Rivers play a major role in assimilating or carrying industrial and municipal waste water, manure discharge and runoff which are responsible for water river pollution [1] [2]. The degree of pollution is generally assessed by studying physical and chemical characteristics of the water bodies [3] Iraqi inland waters witness tremendous impacts through discharges of manufacturers, agricultural and domestic sewage [4] [5]. Quite few studies were performed on Tigris River [6] [7] [8], but no work had considered Al-Garaf canal in Al-Haay City.…”

Monthly variations in Physio-chemical parameters of Al-Garraf, one of the main tributaries of the Tigris river were investigated from October 2012 to April 2013. The study location situated in the south-eastern sector of Iraq and surrounded by wide and fertile agricultural lands. Three stations were selected to. The former is located at 2 km of AL-Haay City as control. The second is situated at distance 2 km away from the former represented study area and the latter station is located at 4 km apart from the second one. Collecting samples monthly, two samples were taken each month . In the present study fourteen physical and chemical parameters were analyzed based on the importance of these parameters. These Fourteen parameters are ranged as following: air temperature (16 to 32) ºC, water temperature (11 to 26) ºC, pH (7.05to 8.35), E.C. (827 to1558) μS/cm, salinity ( 0.54 to 0.99) ppt, DO (7.04 to 10.38) mg/L , BOD ( 0.90 to 7.01) mg/L ,turbidity (31.0 to 177.0) NTU, TDS (550.78 to 1108) mg/L , TSS (38 to 636.5) mg/L 080, T.H (275 to 500) mg/L , Cl- (89 to 184.6) mg/L, NO3 (5.7 to 15.76) mg/L and PO4 (0.15 to 0.5) mg/L.

“…In a study was proved that Cd body content of the G. affinis was increased much higher from water than the food [14,15]. Klerks and Lentz (1998) reported that the tissue metal levels of mosquitofish were highly elevated for lead and (to a lesser extent) for zinc in a contaminated habitat [16]. Franssen (2009) studied the effects of heavy metal mine drainage on population size structure, reproduction, and condition of G. affinis [17].…”

The purpose of this study was to evaluate the levels of heavy metal bioconcentration of the mosquitofish (Gambusia affinis) in Shadegan international wetland. Sampling including the water, waterbed sediment and mosquitofish was carried out from the selected sampling sites during October and November 2011, and analyzed by the ICP-OES. Results show that the water has poor qualitative condition, according to EPA and WHO water quality standards. The level of the water Cr in the selected sites in both months and the levels of Fe, Mn and Zn during October in the SW1 site were higher than the instrumental detection limits indicating that the water was contaminated with these metals in the mentioned sites and months. The levels of the waterbed sediment As, Co, Cr, Cu, Fe, Mn, Pb and Zn, and mosquitofish Cr, Cu, Fe, Mn, Zn, Co and Cd were much higher than the instrumental detection limits, indicating that the waterbed sediment and mosquitofish were contaminated with them during October and November in the selected sites. Statistical assessments reveal that there is a significant difference between the mentioned contaminated water, waterbed sediment and mosquitofish heavy metals (all P-values < 0.05). In overall, it is considered that the contaminated heavy metals can be accumulated in the waterbed sediment and bioconcentrated in the wildlife tissues, then finally can be entered in the marine food chains and biomagnified there after long periods. In conclusion, this paper confirmed that the G. affinis can be used as a bioindicator of heavy metal pollution in marine ecosystems such as wetlands.
