Trace metals in the bottom sediments of the harbour of Lagos, Nigeria.
A study has been made of the heavy metal contents of sediments in the harbour of Lagos which receives a variety of human and industrial wastes. The results indicate three areas with low, medium and high pollution by heavy metals. The harbour in which most shipping activities are concentrated has a low level of pollution. Both other areas with medium and high pollution by heavy metals are located at the entrance and in northwest sections of the harbour respectively, which receive effluents from industries and communities.
