“…Accumulation of chemicals in marine resources, habitat loss and decrease of biodiversity are often related to environmental contamination. Metals are persistent in the environment and often displaying concentrations considered toxic (Ikem and Egiebor, 2005;Khansari et al, 2005). The mechanisms of contaminant accumulation in remote areas far from point sources is insufficiently documented and a challenge for the scientific community.…”

Abstract:Tunas are at the top of the food chains and have high metabolism and feeding rates, leading to increased metal accumulation in their tissues. Several tools using biological, biochemical and chemical measurements have been used to identify populations, geographic distributions and migrations of fish species in different environments. Elemental composition (V, Cr, Co, Ni, Cu, Zn, As, Se, Cd and Pb) was determined in muscle and liver tissues of bigeye tuna (Thunnus obesus) caught in three areas of the south Atlantic Ocean. Concentrations in liver (V, Co, Cu, Zn, As, Cd and Pb) point to increased values in specimens captured near the South Africa and South America relatively to the open-ocean areas. The obtained results showed that tissue elemental concentrations in T. obesus from the south Atlantic areas can be used as a natural tag. Due to its role, liver seems to be the best indicator tissue.

This research determined the concentration of Lead (Pb) and Cadmium (Cd) in roasted corn (Zea mays), roasted plantain (Musa paradisiaca) and barbecue from roadside close to industrial and automobile emission in some selected parts of Lagos and Ota, South-West Nigeria. They were analysed after digestion by Atomic Absorption Spectrophotometry (AAS). Lead had the highest concentration in all the food type analyzed and was higher than FAO permissible limit (0.3 mg/kg) in about 92% of the samples analyzed. It was also found to be higher in the samples from Lagos than those from Ota. While Cadmium had relatively lower concentration compared with Lead in all the food samples but about 25% of the samples analyzed had higher concentration than the FAO permissible limit (0.5 mg/kg). The results showed that the order of the concentration of Lead in the food samples was corn>barbecue>plantain, while the order of the Cadmium concentration in the food samples was in the order corn>plantain>barbecue. Continual consumption of roasted corn, roasted plantain and barbecue close to highway and industrial emission may therefore constitute a source of exposure to these heavy metals.
