“…Studies focusing on the lagoon contamination by organic pollutants are scarce. The few available were based on few locations along the Moroccan coastline and on different environmental matrices or contaminants (Azdi et al, 2006;Bloundi et al, 2008;Er-Raioui et al, 2009;Piazza et al, 2009;Scarpato et al, 2010), but all agree in evidencing a situation of increasing contamination linked to anthropogenic activities.…”

“…However, only few studies have been carried out so far, describing the potential threat of organic pollution to Moroccan aquatic ecosystem (Azdi et al 2006;Chafik 2009;Er-Raioui et al 2009;Hajjaj Hassani et al 2006). The contamination with polycyclic aromatic hydrocarbons (PAH) has not yet been studied in fish from Moroccan waters.…”

Environmental pollution of fish with organic contaminants is a topic of rising attention in Morocco. Polycyclic aromatic hydrocarbons (PAH) are prominent organic contaminants which are rapidly metabolized in fish. Their metabolites are accumulated in the bile fluid and can be used to assess PAH exposure. The two PAH metabolites 1-hydroxypyrene and 1-hydroxyphenanthrene were quantified in European eels (Anguilla anguilla) from two Moroccan river systems by high-performance liquid chromatography with fluorescence detection. Mean values ranged from 52 to 210 ng/mL 1-hydroxypyrene and from 61 to 73 ng/mL 1-hydroxyphenanthrene. The overall concentrations of PAH metabolites in eel from Morocco appeared moderate compared to eel from European rivers and coastal sites. The present study provides first information on concentrations of PAH metabolites in fish from Morocco.

“…The light hydrocarbons migrate more easily, at the expense of the polar compounds which, thanks to their functional groupings, remain attached to the mineral matrix by adsorption [31,32]. Samples taken from Moroccan Mediterranean coasts, showed hydrocarbon composition dominated by the light compounds fraction which could reach up to 70% [33].…”

“…The most represented compounds correspond to anthracene and triphenyl-methane. These compounds are mostly phenyl groups derived from anthropogenic hydrocarbons (industrial activities) [33].…”

“…The impact of this latter was clearly shown on the rocks of the Ksar Sghir site, where it is remarkable an important tarry deposit [34]. The qualitative and quantitative analysis point out two important origins of hydrocarbons: natural source linked to phytoplankton, bacteria and continental plants and anthropogenic source related to petrogenic inputs from harbours and fishing activities and urban dismissals emanating from coastal agglomerations [33].…”
