Phytoremediation potential of weeds in heavy metal contaminated soils of the Bassa Industrial Zone of Douala, Cameroon.

摘要: Phytoremediation is a promising option for reclaiming soils contaminated with toxic metals, using plants high potentials extraction, stabilization and hyperaccumulation. This study was conducted in Cameroon, at the Bassa Industrial Zone of Douala 2011, to assess total content 19 heavy metals 5 other elements phytoremediation potential 12 weeds. Partial extraction carried out soil, plant root shoot samples. evaluated terms Biological Concentration Factor, Translocation Factor Accumulation Coefficient. The detectable Cu:70–179, Pb:8–130, Zn:200–971, Ni:74–296, Co:31–90, Mn:1983–4139, V:165–383, Cr:42–1054, Ba:26–239, Sc:21–56, Al:6.11–9.84, Th:7–22, Sr:30–190, La:52–115, Zr:111–341, Y:10–49, Nb:90–172 mg kg−1, Ti:2.73–4.09 Fe:12–16.24 wt%. contamination index revealed that were slightly heavily while geoaccumulation...
