Small scale gold mining and processing is carried out in 34 (64%) while cement production is prevalent in 33 (62%) of the African countries (Table 6.10 and Figure 6.16). Both of these activities pollute the environment with mercury. Environmental pollution and negative health effects due to poor use of mercury as well as degradation of water resources is a major source of concern.
Intensified training, awareness and making available alternative sources of income and cement substitutes are among the measures required to minimize the problem in these areas.
