“…It is chosen because of its proximity to most of the industrial and maritime activities taking place, such as maritime transport and fishing, and the company of oil Refinery. This Canal possesses a navigable depth of 15 m with a length of 2.7 km, and a width of about 370 m. It receives domestic raw sewage, household waste, and industrial wastes from its neighbourhood (Kouakou et al, 2016a).…”

“…In this study, the significant high Pb concentrations in the sediments are probably originated from anthropogenic activities including waste disposal, maritime activities, and boat traffic (Bakary et al, 2015). Vridi Canal is the area where cruise boats and deep draft vessels daily transit the water of the harbour in Abidjan seaport (Kouakou et al, 2016a). It has been reported that the navigation of deep draft vessels leads to an intense sediment resuspension in seaport (Martínez-Soto et al, 2016).…”

“…The extent of incorporation of Pb in soft tissues of the gasptropod from sediments depends on Pb concentrations in the sediments. Gastropod P. haemastostoma species are known to bioaccumulate contaminants (Kouakou et al, 2016a) at water sediment interface via filter feeding. In this study, Pb accumulation in soft tissues of P. haemastostoma increased with the increasing total concentration of Pb in the sediments.…”

“…This is the case of Vridi Canal where gastropods P. haemastostoma are highly consumed by habitants. Moreover, Kouakou et al (2016a) have reported high levels of Cd and Zn in P. haemastostoma in Vridi Canal. However, there is no report about Pb in the tissues of P. haemastostoma in this area.…”

“…In Côte d'Ivoire, Vridi Canal is the unique way to enter and exit of Abidjan seaport area (Kouakou et al, 2016a). The intense ship traffic and the high fishing fleet increase the potential risk of lead contamination in the surface sediments of this area.…”

Lead (Pb) is one of the most frequent and toxic contaminant in the environment. It can be bioaccumulated by marine organisms through contaminated sediments as well as their food chains. The current study aimed at investigating Pb occurrence in the sediments and gastropod P. haemastostoma from Vridi Canal. Sediment samples were taken using a Van Veen steel grab of 0.02 m2 area, sealed in plastic bags and transported to the laboratory at 4 °C. Gastropod P. haemastostoma species were collected manually using gloves, and then placed in polyethylene plastic bags. The different concentrations were determined using atomic absorption spectrometer Varian AA 20. The results showed seasonal variability of Pb concentrations in sediments and P. haemastostoma. In the both matrices, Pb exhibited the same trend in the distribution between the seasons. This study also mentioned that sediments were highly contaminated by Pb (54.27-134.71 mg/kg). Vridi Canal was found to be one of the most contaminated seaport area. Pb levels (49.55-104.19 mg/kg) in P. haemastostoma exceeding the maximum permitted levels according to the United Nations Food and Agriculture Organization (FAO). This research demonstrated that sediments having lower ecological risk may be resulting in lower tissue Pb of P. haemastostoma. Keywords: Metal Pb, sediment, P. haemastostoma, seasonal variation

Some heavy elements accumulated levels, such as Lead, Zinc, Copper, Iron, Cobalt, Cadmium and Mercury were measured in molluscs that inhabitant the irrigation channel of University of Baghdad in AL- Jadriya districts. The shells and tissues of two Molluscs groups, gastropods genus Viviparous and bivalve genus Anodonta, as well as samples of gastropods eggs and water, were analyzing. The results showed that the highest concentration of Lead, Zinc, Copper, and Iron were recorded in Viviparous shells compared to Anodonta shells, but both Cadmium and Cobalt concentrations were identical in both genera shells, any presence of mercury was not recorded in any of these samples. The tissue samples recorded a rise in Zinc and Copper concentration in Viviparous in comparison with Anodonta, but the Lead, Iron and Cadmium concentrations recorded the highest values in Anodonta. Both elements Cobalt and Mercury concentration showed a similarity in both genera. The gastropods eggs were recorded high concentrations of heavy elements as follows Iron (550.00 ±0.57), Lead (128.00±0.57), Zinc (54. ±000.57), Copper (84.00±0.57), Cadmium (0.300±0.05), Cobalt (0.050±0.01) and Mercury (0.001±0.00) ppm. But water samples showed low concentrations in these elements, Iron (0.200±0.05), Lead (0.033±0.008), Zinc (0.025±0.001), Copper (0.008±0.001), Cadmium (0.004±0.001) and Cobalt (0.001±0.00) ppm.
