Isotherms and thermodynamic studies on adsorption of copper on powder of shed pods of Acacia nilotica

  This study describes adsorption effectiveness of Acacia nilotica pod powder in removing Cu2+ ions in order to consider its application in wastewater purification. The batch method has been employed, using metal concentrations in solution and the percentage adsorption was determined for the adsorption system as a function of adsorbate concentration. Effects of the temperature of the...

The use of spider webs for environmental determination of suspended trace metals in industrial and residential areas

  Spider webs were collected from industrial and residential areas in order to establish the level of suspended heavy metals in the atmosphere. The spider webs were treated with nitric acid and digested before analysis using atomic absorption spectrophotometer (AAS). The mean concentration value of some heavy metals were found to be significantly high at p < 0.05 in suspended particles in industrial areas...

The level of persistent, bioaccumulative, and toxic (PBT) organic micropollutants contamination of Lagos soils

  Lagos is a highly urbanized coastal city, with several water channels linking the Lagos lagoon, a major source of seafoods to the people of Lagos and its environs. Contamination of Lagos soil with persistent bioaccumulative and toxic organic micropullutants (PBTs) would not only affect the non-target species residing in the soil, but also a concern that the chemicals could find their way into the lagoon via...
