With further development this organism may also be useful for monitoring industrial effluent characteristics at the discharge site, allowing rapid, reliable and inexpensive control of water quality. In contrast, the mussel is of doubtful use as an indicator of copper; other indicator types such as ...
With these physiological properties M. edulis is an ideal indicator organism for lead pollution in the marine environment. A biologic calibration curve, the relationship between lead concentration in the mussels' whole soft parts at equilibrium and lead concentration in sea water, is presented. 展开 ...
2.4. Biochemical indicator detection The gill samples were homogenized at a ratio of 1:9 (w/v) in 0.9% ice-cold saline and centrifuged at 10,000 rpm for 10 min (4 ℃), after which the supernatant was obtained for biochemical parameter analyses. The Na+-K+-ATPase activities (Cat No. ...
In this study, we investigated the possibility of sexing juveniles by skin colour in common toads (Bufo bufo). This species is abundant throughout Europe and in northern Asia, occupying various habitats including human-modified environments, so it is a useful potential indicator as it can be stu...

Fish occupy the highest trophic level in aquatic systems that have been recognized as a good bio-indicator due to the ability of their tissue to accumulate heavy metals and other organic pollutants [7,8]. The bioaccumulation of heavy metals in fish tissue is caused by pollution of water with...
No significant changes were observed in indicator of lipid peroxidation (MDA) and in whole-body biomarkers of antioxidant activity (GST, GSH, SOD and CAT) after exposure to both SMF and EMF (t-test, Mann-Whitney U test, P > 0.05; Fig. 2, Fig. 3). Download: Download high-res image ...
The study provides valuable information on effects of neonicotinoid insecticides on a non-target organism, the crayfish, an indicator of pollution and an important element of stable aquatic ecosystems. (c) 2018 Elsevier B.V. All rights reserved....
