Effect of water quality on hematological and biochemical parameters of Gobius niger caught in Faro lake (Sicily)
In many countries, environmental risk assessment is still based solely on chemical analyses that do not suffice to evaluate the complex toxic effects on the environment. This latter derives from the combined effects of chemicals, their decomposition products, and the physical environment can only be evaluated by biological test using biomarkers (McCarthy and Shugart, 1990). Biomarker analysis of field-collected organisms can provide information on the status of the environment, avoiding the need and uncertainty inherent to the extrapolation of laboratory results (Menezes et al., 2006). Biomarkers are defined as a change in a biological response, ranging from molecular to cellular and from physiological responses to behavioural changes which can be related to the toxic exposure or to the toxic effects of environmental chemicals (Depledge et al., 1995). The use of selected biomarkers has become attractive and useful for monitoring environmental quality and the health of fish inhabiting polluted ecosystems (Fernandes et al., 2008).
