Heavy Metal Fluxes in Tropical Urban Forest Soil in Abidjan District (Côte d’Ivoire)

In Western Africa, the growth of cities has led to natural resource pollution, especially air pollution. Urban forests play a key role in filtering atmospheric particles and pollutants through canopy before reaching soil. This study aims quantify heavy metal fluxes an urban forest district Abidjan order assess its protection resources. A monitoring wet deposition (throughfall open field rain) litterfall was carried out for six months National Floristic Center located Abidjan, C?te d’Ivoire. The results show that soil this is ferralsol type characterized by sandy-clay texture low load coarse elements. annual estimated 12.16 ± 0.71 t·ha-1·yr-1, similar other tropical forests. Annual quantities rain throughfall are range rainfall recorded (2013 152 1773 51 mm). Chemical analyses showed litter contain Mn, Zn, Ni, Cr, Cd Hg. Manganese Zn most abundant elements Hg least both litter. main source input metals into associated with biological recycling contributes 109 times greater than carry depositions (open throughfall). However, detailed constitutes barrier transfer indicated decrease content from throughfall. Consequently, recommends creation maintenance increase biomass improve quality West African undergoing constant change development.
