  1. Gill damage, metallothionein gene expression and metal accumulation in <em>Tilapia sparrmanii</em> from selected field sites at Rustenburg and Potchefstroom, South Africa

    Gill damage, metallothionein gene expression and metal accumulation in <em>Tilapia sparrmanii</em> from selected field sites at Rustenburg and Potchefstroom, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Fish were collected from field sites in the mining and agricultural areas of Potchefstroom and Rustenburg, North-West Province, South Africa. Water and sediment samples from each site, together with fish muscle and gills, were analysed by Inductively Coupled Plasma Mass...
  2. Bioaccumulation of metals in <em>Tilapia zillii</em> from Badeni Dam, Côte d'Ivoire

    Bioaccumulation of metals in <em>Tilapia zillii</em> from Badeni Dam, Côte d'Ivoire

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Given the importance of fish as a source of protein and the potential for exposure of humans to metal elements, metal bioaccumulation concentrations in Tilapia zillii from four sites in the Badeni Dam on the Badeni River, Côte d'Ivoire, were...
  3. Lead accumulation in and its haematological effects on African catfish <em>Clarias gariepinus</em>

    Lead accumulation in and its haematological effects on African catfish <em>Clarias gariepinus</em>

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Young adult Clarias gariepinus exposed to 0.0015–0.1500 µg l−1 concentrations of lead (Pb2+) ions for 30 days were investigated for accumulations in muscle, gill, liver and heart tissues, as well as for the metal's effects on haemoglobin concentrations, erythrocytes sedimentation...
  4. Polycyclic aromatic hydrocarbons in water, sediment and fish from the Warri River at Ubeji, Niger Delta, Nigeria

    Polycyclic aromatic hydrocarbons in water, sediment and fish from the Warri River at Ubeji, Niger Delta, Nigeria

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The Warri River at Ubeji, Nigeria, receives pollutants from an oil refinery. The levels of 16 priority polycyclic aromatic hydrocarbons (PAHs) in water, sediment and the tissue of tilapia from the Warri River were investigated in 2010 using gas chromatography...
  5. An evaluation of the weight of evidence approach to assess sediment quality in the Mvoti Estuary, KwaZulu-Natal, South Africa

    An evaluation of the weight of evidence approach to assess sediment quality in the Mvoti Estuary, KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    A weight of evidence approach was evaluated in the Mvoti Estuary, which is affected by point and non-point sources of contaminants. Four sites were sampled in 2005 and assessed along the standard sediment quality triad lines of evidence: sediment chemistry,...
  6. Metal contamination and human health risk associated with the consumption of <em>Labeo rosae</em> from the Olifants River system, South Africa

    Metal contamination and human health risk associated with the consumption of <em>Labeo rosae</em> from the Olifants River system, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The Olifants River, a tributary of the Limpopo River system, is one of the most polluted rivers in South Africa. In May 2011 the concentrations of metals in fish muscle tissue from two impoundments, Loskop and Flag Boshielo dams, on...
  7. Determination of water quality, and trace metals in endemic <em>Sarotherodon linellii</em>, <em>Pungu maclareni</em> and <em>Clarias maclareni</em>, in crater Lake Barombi Mbo, Cameroon

    Determination of water quality, and trace metals in endemic <em>Sarotherodon linellii</em>, <em>Pungu maclareni</em> and <em>Clarias maclareni</em>, in crater Lake Barombi Mbo, Cameroon

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Considering water pollution as a potential threat to some endemic cichlids of Lake Barombi Mbo, Cameroon, an investigation was done in 2011 to determine trace metals in its water, linking their uptake in gills and liver of fish to water...
  8. Heavy metal contamination of water and fish in peri-urban dams around Bulawayo, Zimbabwe

    Heavy metal contamination of water and fish in peri-urban dams around Bulawayo, Zimbabwe

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Urban effluents are significant sources of heavy metal pollution in fresh water. Metal contamination in dams around the city of Bulawayo, Zimbabwe, were monitored during October 2014 to assess ecological and public health risks. Heavy metals were measured in water,...
