“…Hence, the determination of harmful and toxic substances in water, sediment and biota gives direct information on the significance of pollution in the aquatic environment (Hugget et al,1973;Gbaruko and Friday, 2007). Also, studies on the pollution status of some fauna in some parts of Nigeria and around Niger Delta area have been reported (Chindah and Braide, 2003;Davies et al, 2006).…”

Heavy metal (HM) contents in periwinkle and tilapia from Warri coastal water were carried out during dry and wet seasons of 2008 and 2009. Samples were collected from ten sampling locations. HM was determined using atomic absorption spectrophotometer-varian model spectral AA 220. The range of HM concentrations viz Pb, Ni, Fe, Cu, Zn, Cd, Mn and Cr in periwinkle were found to be 0.68-10.34mg/kg, 1.21-8.01mg/kg, 198.73-457.11mg/kg, 0.002-4.60mg/kg, 1.02-5.06mg/kg, 0.002-0.54mg/kg, 10.00-72.27mg/kg and 205.09-1,453mg/kg respectively. In tilapia, the concentrations ranged from 0.73-3.25mg/kg, 0.72-482.00mg/kg, 0.001-1.93mg/kg, 3.02-459.00mg/kg, 0.83-3.75mg/kg, 0.65-1.45mg/kg,1.25-5.01mg/kg and 344.02-969.00mg/kg respectively. The results show that Fe, Mn and Cr in periwinkle and only Cr in tilapia were higher than other metals determined. The concentrations of heavy metals during wet season were slightly higher than dry season except in few occasions. Also, the heavy metal concentrations of the year 2009 were generally higher than the year 2008 indicating more of these metals were discharged or introduced into water/sediment environment than the previous year which enhanced bio-accumulation in these fauna. These generally suggest an evidence of these fauna to bio-concentrate these metals.

Bioaccumulation of heavy metals in fauna and flora in the Ijaw area of the Niger Delta of Nigeria were investigated. The fauna-molluscs and crustacea, and flora Hibiscus esculentus and vernonia amygdalina were selected for this study. Results show that Molluscs and crustacea accumulate considerable amounts of heavy metals. Higher levels of all the metals determined Hg, Pb, Cr, Cu, Ni, and Zn were observed in the shells than in the fleshly tissues. Hibiscus esculentus and vernonia amygdalina also accumulated these heavy metals. The mercury levels in the roots of Hibiscus esculentus and vernonia amygdalina is 0.010 µg/g ± 0.00, while the stem 0.17 ± 0.03 µg/g and leaves 0.25 ± 0.02µg/g was recorded for the v. amygdalina. The H. esculenta fruit has lead levels of 0.22 ± 0.03 µg/g. The levels of Cu, Ni, and Zn are generally higher than those of Hg, Pb and Cr in all the samples analyzed. There is a growing concern about the physiological and behavioral effects of environmental trace metals in human population. The toxicity of lead at high levels of exposure is well known but of a major concern is the possibility that continual exposure to relatively low levels of these heavy metals through the consumption of these fauna and flora may entail adverse health effects.

“…All aquatic organisms can concentrate heavy metals from their surrounding water, sediments or food and they are able to regulate the concentrations of metals in their tissues, to be stored in non-available forms and hence regulate toxic effects by controlling absorption, excretion, and depuration rates or by detoxification either by changing the metal to a less toxic form or by storage at sites in the body where the metal does not have an adverse effect (Hugget et al, 1973). The mean heavy metals concentration for sediments in the lake and mean heavy metals concentration for snails into two different sampling sites are shown in Table 6.…”

-Saint-Augustin Lake is an urban lake in Que´bec, Canada that has been subjected to long periods of direct human impact, mainly due to agricultural and urban activities, with great changes in trophic status and chemistry occurring within the last few decades. In 2009, during an examination of the lake bottom substrate, the presence of the invasive species Cipangopaludina chinensis (Reeve, 1863) was found on floor bottom sediments. The gastropods soft tissues were mineralized and analyzed by ICP-OES. The purpose of this study was to estimate concentrations of heavy metals in C. chinensis, describing the relations of these values with the sediment metal. In gastropod soft tissues the overall common trend in the heavy metal concentrations was revealed in the following order: Fe > Mn > Zn > Cu > As > Ni > Pb > Cd > Cr. Biota-sediment accumulation factors (BSAFs) have shown that C. chinensis cannot be used as a bioindicator of heavy metal pollution and exposure in the Canadian lakes where it is present. In fact, while the sediments of Saint-Augustin Lake are characterized by high metal concentrations, C. chinensis does not have high bioaccumulation factors (BSAFs < 1.0). By literature comparison with other aquatic organisms in polluted ecosystems at different latitudes it was possible to affirm that the concentrations of Fe, Mn and Zn in C. chinensis tissues are considerable if compared with these sites.
