Assessment of the metals contamination of the low Sebou sediments (Morocco).

The heavy metals contamination of the lower Sebou sediments was studied to determine the average degree of contamination and to assess the extent of anthropogenic contamination. The spatial and temporal distribution of these metals and the results of the contamination indices showed very serious metallic contamination principally of Cr, Pb and Hg. However accurate analysis of the situation in the river mouth was complicated by the fact that the metals could be moved by the tides and currents.

Fungal microflora biodiversity as a function of pollution in Oued Sebou (Morocco).

An inventory of the fungal microflora present in sediments collected at 11 sites along Oued Sebou has been established. The influence of some climatic parameters (temperature, rainfall) and of pollution on the composition of the fungal communities has been questioned. Emericella nidulans, Eurotium amstelodami, Neosartotya fisheri var.
