“…In fact, the pollution in this coast is due essentially to the presence of continuous discharge of heavy metals from local industrial activities (Hamza-Chaffai et al 1997, 1998 and from the phosphogypsum stock (Illou 1999;Serbaji 2000). Several reports have also indicated high metal concentrations in soft tissues of Reditapes decussatus (Smaoui-Damak et al 2003;Hamza-Chaffai and Pellerin 2003) and in the fish Scorpaena porcus (Hamza-Chaffai et al 1995) from this coast.…”

The present study illustrates an analysis of spinal deformities associated with metal accumulation in natural populations of Zosterisessor ophiocephalus derived from polluted (S1) and unpolluted (S2) areas in the Gulf of Gabès in Tunisia. Three basic types of spinal deformities were detected: kyphosis, scoliosis and lordosis. These basic deformities frequently co-occur. Spinal deformities were observed in 10.72% of the total examined fish (n = 494). Deformed fish were 3.85 times more frequent in S1 than in S2. In both sexes, the highest occurrence of deformities was observed in the 111-120 mm class decreasing thereafter with fish length. Hepatic concentrations of cadmium (Cd), copper (Cu) and zinc (Zn) were significantly higher in Z. ophiocephalus from S1 than those from S2. Comparisons between fish in each site showed that liver concentrations of Cd and Zn were significantly higher in deformed fish than in normal fish. The relationship between metals accumulation and observed spinal deformities as well as the suitability of this kind of studies for environmental monitoring are discussed.

“…In fact, these metals are potential source from industrial activities located in the Gulf of Gabès (Hamza-Chaffai et al 1995;Serbaji 2000;SmaouiDamak et al 2003). Metal analyses were carried out only in females to eliminate any possible interference of sex with metals bioaccumulation.…”

“…Given the fact that the city of Gabes, located in the south east of Tunisia, has faced for the past five decades a major problem of heavy metals pollution (Hamza-Chaffai et al 1995;Serbaji 2000) due to the existence of phosphate industry near by. We compared two natural populations of Gambusia affinis from polluted and unpolluted sites for a number of different parameters (such as: survival and Cd accumulation), both in adults and their offspring after a series of acute exposure experiments.…”

This study aims to demonstrate the influence of animals' origin on their sensitivity toward heavy metals. For this purpose, we compared LC(50) of cadmium in two populations of Gambusia affinis captured in two geographically isolated environments in the east of Tunisia; Oued El Gsil in the city of Monastir (S2) and Oued Chenini in the region of Gabes (S1). Although physicochemical parameters of the water (pH, dissolved oxygen and salinity) are similar in the two studied sites, cadmium concentrations in water, sediments and fish tissues from S1 are significantly higher (P < 0.01) than those from S2, 48-h and 96-h LC(50) of the (S1) population are significantly higher than those from S2. In the same way, the offspring of the polluted site (S1) population exhibit 48-h and 96-h LC(50) values much higher than those of the reference site (S2) population. These results show that the population of the Gabes region is more resistant to cadmium than that of the Monastir region and that this resistance could have a genetic basis. These results indicate the influence of the origin of animals that has to be taken into account not only in laboratory toxicity tests, but also in field ecotoxicological studies.

“…Biochemical mechanisms within organisms tend to regulate essential trace elements at constant concentrations [93]. It is well established that MT has a role in Zn homeostasis and Zn is a constituent element of MT [94]. Zn toxicity effects will occur during exposure to elevated concentrations [95], although Zn toxicity is rather uncommon in fish [48], the free Zn 2+ is indeed, extremely toxic to the cell.…”
