Contaminations en éléments traces métalliques des termitières autour de Lubumbashi

The disappearance of vegetation in the PengaPenga areahood ( Gecamines) was an indication of the environment degradation. High contents of traces elements from humankind were the cause of this degradation; the contamination source was mainly due to wind motion that contributes to accumulation of pollutants on deposit site. Elements traces content were determined from soils samples from PengaPenga and Kassapa termites. The following parameters were assessed: pH, particle size, Cu,Co,Pb,Zn, and Cd contents using physico-chemical methods of analysis.
Both colors red and yellow of termites were used to ascertain out contamination of soil. Traces such as copper, zinc and others metals were originated from mining process of those metals. Environmental conditions such as wind and rain water play a major role in spreading out traces metal which emanated from Gecamines chimney smoke.
Results showed that traces elements from sampled soil are the main cause of contamination (pollution) of PengaPenga areahoood. Whereas termites had shown different concentrations in terms of pollutants
