Polychlorinated Biphenyls in Sediments from Bizerte Lagoon, Tunisia

Gonadosomatic index and gonad histopathology of Gobius niger (Gobiidea, Teleost) from Bizerta lagoon (Tunisia): Evidence of reproduction disturbance

“…This lagoon is faced to many anthropogenic pressures including urbanisation, industrial and agricultural activities as well as naval and commercial shipping harbours. Thus, direct and indirect discharges of wastes and runoff lead to the chemical contamination of the lagoon by various toxic compounds such as heavy metals (Yoshida et al, 2002), organo-chlorinated pesticides (Cheikh et al, 2002), halogenated aromatics compounds like polychlorobiphenyls (PCBs) (Derouiche et al, 2004), polycyclic aromatic hydrocarbons (PAHs) (Louiz et al, 2008) and organotins (Mzoughi et al, 2005). As a possible consequence of extensive activities, annual fish productivity of this lagoon records a drop which is accentuated from a year to another.…”

Occurrence of polycyclic aromatic hydrocarbons (PAHs) in mussel (Mytilus galloprovincialis) and eel (Anguilla anguilla) from Bizerte lagoon, Tunisia, and associated human health risk assessment

“…Meanwhile, this lagoon has been subjected to many anthropogenic pressures including urbanization, agricultural activities (pesticides and chemical fertilizers), industrial activities (cement works, metallurgical industry, boatyards), and naval and commercial shipping activities. The direct and indirect discharges of urban, agricultural and industrial wastes and runoff have resulted in the increase of chemical contamination of the lagoon by various toxic compounds such as polychlorinated biphenyls (PCBs) (Derouiche et al, 2004;Ben Ameur et al, 2013;Barhoumi et al, 2014a), organochlorine pesticides (OCPs) (Ben Ameur et al, 2013;Barhoumi et al, 2014a), polycyclic aromatic hydrocarbons (PAHs) (Trabelsi and Driss, 2005;Barhoumi et al, 2014b), polybrominated diphenyl ethers (PBDEs) and their methoxylated analogues (MeO-PBDEs) (Ben Ameur et al, 2011, organotins (Abidli et al, 2011) and heavy metals (Ben Garali et al, 2010). This has led to a decrease in bivalve and fish production over the last few decades (ANPE, 1990).…”

Changes of benthic bacteria and meiofauna assemblages during bio-treatments of anthracene-contaminated sediments from Bizerta lagoon (Tunisia)

“…This area extends over 150 km 2 and has a mean depth of 7 m, and is connected to the Mediterranean Sea through a 6-km-long inlet and to the Ichkeul Lake through the Tinja channel. Bizerta lagoon constitutes a receptor of several industrial sewages, aquaculture wastes, fertilizers, and pesticides through runoff and soil erosion, and wastewaters from towns implanted around (Yoshida et al 2002;Derouiche et al 2004;Ben Said et al 2010). Consequently, Bizerta sediments are contaminated by PAH compounds especially in the canal where most of the industrial activities are concentrated (Ben Said et al 2010).…”
