L’objectif de la Cellule Latitudes Sud au sein de l'Aquapôle de l'Université de Liège est de favoriser le développement de projets liés à l’eau dans les pays du Sud, et en particulier dans les pays en développement. La Cellule Latitudes Sud intervient au niveau de la promotion, la réalisation et/ou la collaboration à différents projets avec une approche pluridisciplinaire et plurisectorielle. Elle s’appuie sur les compétences de l’Aquapôle (ULg) et également sur le réseau de compétences que constituent ses services membres. [less ▲]

A study of the zonation of the aquatic bryophyte assemblages from the Anterior Rhine to the Middle Rhine is presented. The typology obtained differs from the hydrogeoinorphological classification because the correction of the river has led to the homogenization of habitats. Since the straightening of the river in the course of the 19th century, the embankments have created more stable habitats on which mountain species formerly characteristic of the rapids of the High Rhine appeared. During the 20th century, regulation, the construction of hydroelectric powerstations even the canalization of the river in Alsace. have caused a great change in water level. On the Upper Rhine, the rcgularisation of the water level .'allowed the appearance and the spread of strict hydrophytes such as Octodiceras fontanum which is now common between Rastatt and Bonn. Conversely, species characteristic of variable water levels decreased or disappeared. The industrial development along the river has caused water quality to severely decrease downstream of the industrial areas, hence the decrease or the disappearance of their primary flora in favour of pollution-tolerant assemblages. The former side channels of the Upper Rhine in France that have been disconnected from the main river and fed by groundwater since canalization, possess a bryophyte flora very similar to that of good quality waters in the upstream part of the High Rhine or in the Alpine Rhine. This flora is the last regional relic of a flora that has disappeared from the main channel due to water pollution. These refugia should consequently be preserved from the flooding of alluvial forests, part of the flood management program. [less ▲]

Jaccard's distances between the aquatic bryophyte assemblages recorded in 1972-1973 and in 1997 in nine study sites along the Belgian course of the rivers Meuse and Sambre were correlated with the differences of concentrations of 13 physico-chemical factors (O2, N-NO2-. N-NH4+, N-NO3-, P-PO43-, K+, pH, Ca++, Fe, Cu, Pb, Zn and Mn) between 1972-1973 and 1996. The strong decrease in heavy metals pollution and the decrease of the trophic level are correlated with the recolonization of the most polluted sites in the 1970s by the pollution-sensitive species present in the valleys at the beginning of the century. Conversely, N-NO2-, N-N03" and K+ have increased between the two surveys. They currently reach much higher concentrations in the Sambre than in the Meuse, as well as N and micro-pollutants such as pyrene and anionic detergents. The different loads of these factors in the studied rivers might explain their different recolonization patterns. Although some species might have developed a tolerance to certain factors, an effort to improve the quality of the effluents coming from industrial areas still remains to be made, especially in the frame of the projects of river flooding of the riverine areas.

One of the most versatile methods to prepare TiO2 fine powders and films is the sol-gel technique. It offers many advantages, among which the possibility to control the stoichiometry, work in mild and ambient atmospheric conditions and achieve high purity and homogeneity of the final product. Stable TiO2 sols were synthesized by an aqueous sol-gel process using titanium tetraisopropoxide (TTIP) as precursor and nitric acid in water as hydrolyzing agent. The aim of the present study was to investigate the influence of different solvents and different amounts of HNO3 on the photocatalytic activity of TiO2 in the breakdown of ethanol (EtOH) as VOC molecule under UV and visible light. In particular, ethanol, isopropanol and butanol were used as solvents and two different molar ratios of HNO3 with respect to TTIP (0.25 and 0.5 respectively) were used. Their effect was investigated with regard to the photocatalytic properties of the films obtained by spin coating on sodium free glass [1] and heat treated at 450°C in air. The microstructure, optical and morphological properties of the films were investigated using SEM, UV-Vis spectroscopy and ellipsometry. The nature of the crystalline phases was ascertained by X-ray diffraction and the surface area of the powders was measured by N2 adsorption. The porous TiO2 films obtained show quite good photocatalytic activity for the degradation of EtOH compared to titania films prepared using P25 Degussa as shown in Fig. 1. Further the photocatalytic properties of the thin films obtained by aqueous sol-gel method were compared with the activity of films prepared using the same titanium precursor by a non-aqueous sol-gel process, in which the hydrolysis is initialized by esterification reaction between acetic acid and alcohol.
