“…Actually, the use of biomarkers for environmental monitoring comes to complete chemical analysis by providing an integrated evaluation of exposure to pollutants and its effects at different levels of biological organisms. This biological approach of disturbance impact on organisms and ecosystems is relatively recent (McCarthy and Shugart, 1990;Cairns and McCormick, 1992;Symposium, 1992;Peakall and Shugart, 1993;Fossi and Leonzio, 1993;Gestel and Brummelen, 1996;Lagadic et al, 1994;Lagadic, 1998).…”

This study aims to evaluate levels and effects of Polycyclic Aromatic Hydrocarbons (PAHs) in cockles (Acanthocardia tuberculatae) collected from two differently influenced areas in the Mediterranean Western Moroccan coasts. PAHs accumulation was studied in soft tissues using Soxhlet extraction and separation on silica column methods. The measure of those organic compounds was realized by Gas chromatography coupled to Mass spectrometer technics (GC/MS). The impact evaluation was carried out by the study of biochemical responses in gills and digestive gland using two enzymes activities: Glutathione S-Transferase (GST) and Acetylcholinesterase (AchE). The PAHs displayed significant rates of accumulation ranging from 10.12µg/g Dried Weight (DW) to 11.65µg/g (DW) respectively in Oued Laou and Martil sites. Pyrolytic and petrogenic origins were observed in both sites. Pyrolytic origin of PAHs was strongly detected in Oued Laou site while petrogenic origin was mostly detected in Martil site. Biochemical study revealed significant enzymatic response of GST and AchE in gills and digestive gland. The study showed significant biochemical response more important in Martil site than Oued Laou site traduced by GST induction and AchE inhibition. Those results seemed to be related to accumulation rates of PAHs, which was also suggested by the statistical analysis PCA.

“…The chemical and morphological parameters of the blood can provide a wide range of biomarkers; its use has increased because the sampling can be very fast and non-destructive [36]. The hematological parameters can provide evidence of pathology including anemia, dehydration, infectious processes, parasitism, or poisoning [37]. These parameters in turn may be related to pollution and its effects [38].…”

The objective of this chapter is to present the results of a monitoring study carried out with physiological responses (biomarkers) in Rhinella marina (giant toad) for two different years, inhabiting the low basin of Coatzacoalcos river, one of the most contaminated regions in Mexico. A decrease in delta aminolevulinic acid dehydratase (δ-ALAD) (considered inhibition) and in the condition factor (1.2-1.5 times) found in toads of the industrial zone compared with reference organisms, each year. As for the hematological parameters, the mean corpuscular hemoglobin concentrations (MCHC), in the amphibians of industrial zone of the first sampling year show a decrease, while for the second sampling year, show an increment of 1.5 times than organisms of reference site. These effects could be associated with exposure to pollutants such as heavy metals (mainly Pb), which have been registered in different studies. This study demonstrates the usefulness of giant toads as biomonitors of contaminated sites.

“…There is a general consensus that fi sh status is a reliable indicator of environmental health, but most data endpoints are obtained through invasive and, many times, lethal techniques precisely in places where fi sh are scarce. Since the 90's, the ethical considerations are a primary motivation for developing techniques compatible with species protection (Fossi & Leonzio 1994). However, lethal techniques are the one used for monitoring the health of the ecosystem.…”
