“…In some studies, IBR has been used to compare the effect of different concentrations of perfluorinated compounds, as in the cases of Cyprinus carpio (Linnaeus) (Kim et al, 2010), assessing stress in the Yangtze River (Wang et al, 2010), using Carassius auratus as a study organism for evaluating different regions of the Bay of Cannes (Mediterranean Sea), and with mussels (Damiens et al, 2007); most of these studies applied IBR to compare study sites or treatments. In this work, the IBR showed an increase in SOD gill activity in the field group where the level of LPO was also increased, while GPx activity decreased when compared to the control.…”

“…Morphol., 30(3):1139-1149, 2012. 1146 studies, our results indicate no significant difference relative to controls, as also was observed by Ahmad et al and Parvez & Raisuddin in Channa punctata (Bloch) and Anguilla anguilla (Linnaeus), respectively; this similarity may be attributable to an adaptation of the organisms of Yuriria Lake conditions, manifesting as a similar activity of the antioxidant enzymes SOD and CAT (Achuba & Osakwe). It is noteworthy that the decrease in GPx activity may be attributed to inactivation of the same enzymes by free radicals but also has been related to water turbidity (Ahmad et al).In some studies, IBR has been used to compare the effect of different concentrations of perfluorinated compounds, as in the cases of Cyprinus carpio (Linnaeus) (Kim et al, 2010), assessing stress in the Yangtze River (Wang et al, 2010), using Carassius auratus as a study organism for evaluating different regions of the Bay of Cannes (Mediterranean Sea), and with mussels (Damiens et al, 2007); most of these studies applied IBR to compare study sites or treatments.

SUMMARY:In aquatic ecosystems, the complex mixture of pollutants may mediate the formation of free radicals and cause oxidative damage to the biota. Yuriria Lake (a Ramsar site in Central Mexico) receives input of wastewater from its tributaries, agricultural runoff, and municipal discharge. We studied the lipid peroxidation (LPO), antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), and histopathology of gill and liver of the native fish Goodea atripinnis in Yuriria Lake.Results were compared to a control group of fish cultivated in the laboratory. LPO, SOD, and CAT showed no significant differences compared to controls, but GPx showed greater and significant differences in both tissues. Three class sizes were identified; organisms of classes I and II had slight vasocongestion in the liver as compared to controls. Hepatocytes of class III showed cytoplasmic vacuolization, cellular disorganization, and the liver showed marked fibrosis compared to controls. Gills of controls and classes I and II showed no damage in gill filaments. Tissue damage in class III included hypertrophy, loss of the typical morphology, and edema in the gill filaments. The longer exposure of older organisms to Yuriria Lake conditions may have resulted in their poorer health condition.KEY WORDS: Mexican wetlands; Oxidative stress; Histopathology; Fish health condition; Liver; Gill. INTRODUCTIONWetlands are important sites of transition between land and water; these environments are considered among the most productive ecosystems in the world (Environmental Protection Agency, 2001). As in other regions of the world, in Mexico, wetlands serve several functions in the environment, such as storage and filtration of water and as habitat for wildlife (Environmental Protection Agency). These environments are critical stopover and wintering grounds for many of North America's waterfowl and other migratory birds (Wilson & Ryan, 1997) and are of vital importance for fulfilling requirements in the life cycle of migratory and resident Nearctic and Neotropical waterfowl. Unfortunately, they also act as receptors of pollutants over time, and such inputs could have serious consequences for the aquatic biota, outcomes that may not be apparent until they emerge at the population or ecosystem level (Linde-Arias et al., 2008). In Mexico, these ecosystems have undergone processes of transformation for various purposes, but unfortunately a lack of knowledge about their fragility and their inadequate management are among the problems that threaten their conservation (Comisión Nacional del Agua, 2010). One of these consequences is oxidative stress on the biota, which is defined as a disturbance caused by an imbalance between the production of free radicals or pro-oxidant agents and the antioxidant capacity of an organism. Several pollutants when entering water ecosystems become or mediate reactive oxygen species (ROS; O 2 -, OH, H 2 O 2 ), which are highly reactive molecules that interact with critical macromolecules...

“…Therefore, it would be necessary to incorporate them into a general framework facilitating data analysis and interpretation in order to provide an integrated relative measure of the overall health of coastal areas. The integrated biological response (IBR) has been applied in numerous field studies in mussels [39], daphnids [38], green crab Carcinus maenas [40] and in fish [41][42][43].…”

This work aims to assess the spatial and temporal variations of four biomarkers activities and to integrate their biological responses in a battery using the gastropod Phorcus turbinatus. The monitoring was carried out during the period between April 2014 and January 2015 at six stations along the northern and the northeastern coasts of Tunisia. The Fulton condition factor was estimated and the activities of catalase, acetylcholinesterase and glutathione-S-transferase were evaluated by spectrophotometry. A multi-biomarker battery approach was used to assess ecosystems’ condition and to identify environmental impacts on the organisms. The results suggest that the enzymatic activities of CAT and GST depend especially on seasons. As for AChE activity, it was similar between seasons and stations. The values of the integrated biological response were maximal at Jarzouna in summer and at Sidi Daoued in winter, indicating the presence of severe stressors suffered by the organisms. This perturbation may be due to the enrichment of the waters by xenobiotics, namely polycyclic aromatic hydrocarbons, insecticides, phosphate wastes, PCBs and pesticides. Thus, P. turbinatus seems to be a good bioindicator of chemical pollution, constituting an adequate tool for a bio-monitoring program.

Imaging of contaminant plumes using ERT in Qinhuai River water and its bed caused by urban effluents at Nanjing, China

et al. 2015

This paper presents the imaging of contaminant plumes in Qinhuai River and its bed for the remediation strategies of the river. Qinhuai meets with Yangtze River at Nanjing area via inner and outer channels, coursing through urban districts of the city. The discharge of urban effluents has badly affected the water quality of the river. Generally, contamination assessment is carried out through traditional point-based sampling methods. However, these methods are often inadequate to estimate accurately the spatial distribution of contaminants and their extension. Therefore, electrical resistivity tomography (ERT) is applied because of its high quality imaging to investigate contamination and its extension in Qinhuai River and its bed. Eight sites were selected at outer and inner channels of the river. A 2-D inversion of the perceived data was carried out and the obtained resistivity values were converted into salinity after temperature correction. The acquired images of resistivity and salinity show that in low streaming conditions the river has large zones of low resistivity in the water body, which are extending toward underlying bed corresponding to high contamination. Conversely, in high streaming conditions, the low resistivity zone shrinks significantly at almost all the studied sites except Xishan Bridge (site E), which still showed high plume of contamination. This phenomenon reveals that in low streaming conditions the contamination level is high while in high streaming conditions salts are flushed out from the river. This study further demonstrates that ERT method can be a useful technique for the environmental studies of rivers, canals and surface water environments.
