Removal of chromium and lead from drill cuttings using activated palm kernel shell and husk

  Palm kernel shell and Palm kernel husk, two readily available agricultural waste products have been used as low-cost potential adsorbents to remove chromium and lead from drill cuttings. Batch adsorption studies were carried out as a function of parameters such as pH, contact time and carbon dosage. Chromium and Lead removal was found to be pH dependent with the optimum pH for Chromium...

Comparative study of mercury accumulation in some brackish water fishes in a tropical lagoon and its adjacent creek in South Western Nigeria

  The Hg content of some brackish water fishes, water and sediment in Lagos lagoon and Abule - Agege creek were investigated from February to September, 2004. The pH of the lagoon was neutral however the creek was mildly acidic (6.75) in the dry season. The Hg content of the lagoon ranged from 0.27 - 0.40 mg/l for water and 0.46 - 0.56 µg/g dry wt for sediment lower than the creek range (0.41 - 0.42 mg/l...
