Integrated use of biomarkers (acetylcholinesterase and antioxidant enzymes activities) in Mytilus galloprovincialis and Mullus barbatus in an Italian coastal marine area

Measurements of biomarker levels in flounder (Platichthys flesus) and blue mussel (Mytilus trossulus) from the Gulf of Gdańsk (southern Baltic)

“…Bresler et al (1999) observed no differences in GST activity levels of mussels measured from ''clean'' and polluted stations in the German part of the North Sea. The same was observed also for CAT activity in mussels off the Salento Peninsula (Italy) by Lionetto et al (2003). However, both these authors suggest these findings to be caused by biochemical adaptation to chronic exposure to pollutants.…”

Temporal and spatial distribution of semicarbazide in western Laizhou Bay

“…AChE is a key enzyme commonly inhibited by xenobiotic compounds such as organophosphate, carbamate pesticides, polycyclic aromatic hydrocarbon, metals and surfactants (Lionetto et al, 2003;Sole et al, 2010;Gonzalez-Rey and Bebianno, 2014). In the present study, significant inhibition of AChE activity was observed in oysters from XZ, which was coincided with the elevated metal concentrations.…”

Biochemical biomarker responses to pollution in selected sentinel organisms across the Eastern Mediterranean and the Black Sea

“…This lack of response, which contradicts the general expectation that fish are more sensitive than molluscs, particularly as regards AChE inhibition (Monserrat et al 2007;Viarengo et al 2007), is not easily explained, as it has not been possible to undertake an in-depth characterization of the chemicals present in the areas in which the fish were collected. However, our results on D. sargus sargus biomarkers from the Apulian coast (Italy) are in agreement with a previous study in this area by Lionetto et al (2003) that failed to reveal differences in AChE and CAT activities of fish Mullus barbatus from the same sites. These authors attributed the lack of AChE response to the fact that fish were sampled offshore where the distribution of chemicals can be different compared to inshore sites and this can also be the case in the present study.…”

“…The fish sentinel species used in this study (D. sargus sargus and M. surmulletus) showed higher enzymatic activities compared to mussels in accordance with previous studies (Lionetto et al 2003;Kopecka et al 2006), however they did not generally exhibit differences in biomarker levels between the impacted and reference sites. This lack of response, which contradicts the general expectation that fish are more sensitive than molluscs, particularly as regards AChE inhibition (Monserrat et al 2007;Viarengo et al 2007), is not easily explained, as it has not been possible to undertake an in-depth characterization of the chemicals present in the areas in which the fish were collected.…”
