“…Heavy metals (e.g., Fe, Ni, Cd, Cu, Cr, Ba, etc) and many organics like hydrocarbons and pesticides have been reported in various concentrations in many rivers and creeks in the Niger Delta region of Nigeria (Anyakora et al, 2005;Olowoyo et al, 2010;Godwin et al, 2011;Nwabueze, 2011) and these pollutants have a tendency to accumulate in biota (Landrum et al, 2003;Anyakora & Coker, 2007) and undergo food chain magnification (James et al,1998). It is therefore imperative to monitor the concentration of these pollutants in the environment and to analyze bioaccumulation process in order to assess the possible impact on human health and risk which man faces in such an environment (Kotze et al, 1999).…”

A field bioaccumulation study was carried out. Juvenile hemichromis fasciatus in net cages were exposed to contaminated surface water in borrow pits located within oil exploration and production (E & P) installations within the Niger Delta region of Nigeria during wet and dry seasons.Percentage mortality ranged between 2% and 3.8%. Assuming a first order kinetics and steady state at day 14; toxicokinetic variables were obtained for xenobiotics assessed. The up-take rate constant k, ranged from 38.47 Hemichromis fasciatus exhibited greater uptake of analytes in the dry season and the amount of heavy metals accumulated were all below the provisional maximum tolerable daily intake (PMTDI).

“…Synthetic chelating agents (e.g. ethylene diamine tetraacetic acid) can also reduce metal toxicity (Muramoto, 1980;James et al, 1998). Effects of metal toxicity are varied, ranging from gross pathologies like scale deformation (Yoshitomi et al, 1998) and liver degeneration (Woodward et al, 1994), to the disruption of metabolic processes (Barnhoorn et al, 1999) and behaviour (e.g.…”

This is the first paper reporting on results obtained in a metal bioaccumulation study in the Vaal River system. It discusses concentrations of four non-essential elements (strontium, aluminium, lead and nickel) in water, sediment and various fish tissues. A second paper will report on concentration levels of the remaining five essential trace metals (chrome, copper, iron, manganese and zinc) studied. While heavy metals did accumulate in C. gariepinus tissues, no clear trends emerged with regard to differences between localities (Vaal Dam and Vaal River Barrage) or surveys. The highest non-essential element metal concentrations were generally recorded in gill (filaments and arches), followed by muscle, liver and lastly skin. This general trend appears to be in agreement with trends observed by other workers and reported in the literature. Variability in tissue metal concentrations in C. gariepinus within locality and seasons observed in this study is also reflected in results from available literature. This accentuates the importance of factors that influence the concentrations and bioavailability of trace metals.

“…Bu araştırmaların çoğunda metal toksisitesini azaltmakda kullanılan şelatlaştırıcı maddelerle ilgili olduğu rapor edilmiştir [34][35][36] . Özellikle metal toksisitesinin azalmasında Ethylenediaminetetraacetic acid (EDTA), Nitrilotriacetic acid (NTA) ve sitrat gibi birçok şelatlaştırıcı madde kullanılmıştır [37][38][39] . Bunlar içerisinde zeolitler, daha ucuz, hiçbir yan etkisi olmayan, kirli çevrelerden toksik elementlerin gideriminde kullanılan kimyasal bir ajandır.…”

ÖzetBu araştırmada, katyon değiştirebilme yeteneğinde olan zeolitin Nil tilapia (Oreochromis niloticus)'nın kas, karaciğer, solungaç ve böbrek dokularında kurşun birikimi üzerine etkileri incelenmiştir. Balıklar 0.1 mg/l Pb, 0.1 mg/l Pb+0.1 g/l zeolite, 0.1 mg/l Pb + 0.2 g/l zeolite ve 1.0 mg/l Pb, 1.0 mg/l Pb + 0.1 g/l zeolit ve 1.0 mg/l Pb + 0.2 g/l zeolit konsantrasyonundaki karışımının etkisine 10, 20 ve 30 gün sürelerle bırakılarak doku ve organlardaki kurşun birikimi atomik absorbsiyon spektrometresi ile belirlenmiştir. Çalışılan dokularda kurşun birikimi ortam derişiminin ve sürenin uzamasıyla artmıştır. Tüm dokularda kurşun birikimi 10, 20 ve 30 günlerde 0.1 ve 1.0 mg/l kurşun konsantrasyonlarında istatistiksel olarak önemli olduğu saptanmıştır. En yüksek kurşun birikimi böbrek dokusunda oluşmuş, bunu solungaç, karaciğer ve kas dokusu izlemiştir. Etkide kalınan tüm sürelerde O. niloticus'un dokularında kurşun birikimi zeolitin varlığında azalmıştır. Denenen tüm karışımlarda (kurşun + zeolit) zeolit O. niloticus'un böbrek ve karaciğer dokularında kurşun birikimini önemli ölçüde azaltmıştır.

The fish were exposed to 0.1 mg/l Pb, 0.1 mg/l Pb + 0.1 g/l zeolite, 0.1 mg/l Pb + 0.2 g/l zeolite and 1.0 mg/l Pb, 1.0 mg/l Pb + 0.1 g/l zeolite and 1.0 mg/l Pb + 0.2 g/l zeolite mixtures for 10, 20 and 30 days, lead accumulation in tissues were measured by atomic absorbtion spectrophotometry. Lead accumulation increased with increasing concentrations of lead in the medium and with increasing periods of exposure tissues studied. All tissues lead accumulation was found to be statistically significant in the 0.1 and 1.0 mg/l of lead concentrations at 10, 20 and 30 days. Highest accumulation occurred in the kidney followed by gill, liver and muscle. In all exposure period, accumulation of lead in whole tissues of O. niloticus decreased in the presence of zeolite. In both mixed exposure (lead + zeolite) concentrations, zeolite significantly reduced the accumulation of lead in the kidney and liver of O. niloticus.
