  The adsorption of lead (II) onto activated carbon prepared from cow dung was studied under various conditions such as temperature, contact time, pH, adsorbent dosage and concentration of adsorbate. Batch adsorption experiments were conducted and the result showed that the adsorption was pH, temperature, contact times and adsorbate concentration dependent but was partly dependent on the adsorbate dosage. It was rapid, stable and occurs in <100 min. This study showed that activated carbon prepared from cow dung is suitable for the adsorption of metal ions and as such could be used as a cost effective adsorbent in the treatment of the industrial wastewater.

  Atmospheric pollution from municipal refuse dumps and vehicular traffic are matters of growing interest, often leading to temporary restrictions in urban areas. This study aimed at evaluating bioaccumulation and effects caused by airborne pollutants from refuse dumps. Specimens of the moss Funaria capsularis collected in five sites in the urban areas of Zaria and Kaduna, Nigeria and trace metals (cadmium, chromium, copper, iron, lead and zinc) were measured. The overall results of this exploratory study suggest the utility of F. capsularis as a lower plant for biomonitoring the environmental impact of atmospheric pollution in urban areas. The impact of these dump sites on surrounding soils was also studied.
