Assessment of Water Contamination by Metallic Trace Elements at Mining
Sites: The Case of the Ouham River in the Central African Republic
- Authors: Eric FOTO; Oscar ALLAHDIN, Olga BITEMAN, Nicole POUMAYE, Seraphin PINIKO
  Pages: 47 - 56
  Abstract: In a context of sustainable management of natural and environmental resources, the preservation of water quality from the adverse effects of anthropogenic activities is of particular interest. Human activities that generate large amounts of waste containing toxic metals are found in the environment as a result of rainfall, atmospheric deposition, etc. Although naturally present at low concentrations in the earth’s crust, these toxic trace metal elements accumulate in surface waters, sediments and soils and reach high concentrations, threatening aquatic life and human health. The aim of this work is to identify these elements in the vicinity of the mining zone in the Bozoum region of the Central African Republic in order to propose a depollution process using activated bricks as adsorbent support. The parameters measured at the four mine sites were as follows: the suspended solids were in the range of 276 to 504 mg/l, the water turbidity was in the range of 375 to 630 NTU, iron was present at concentrations in the range of 4.21 to 8.97 mg/l, and the abnormally high mercury was in the range of 4 to 26 µg/l, 26 times above the standard. The order of the degree of contamination of the water is thus established Hg> Fe> As> Zn> Cu> Pb=Cd=Mn. The activated brick filtration depollution process shows a good mercury retension capacity with a rate of abatement of 95.83% compared to sand with a rate of 12.5%.

Impact of Micro-Climate Change on the Forest Vegetation Resources of the
Mount Cameroon Region
- Authors: Mukete Beckline; Vivian Ntoko
  Pages: 57 - 66
  Abstract: Over the years, non-timber forest products have become vulnerable to climate change with consequences for their growth, maturity, harvesting and fruiting. As surrounding forest communities continuously depend on forest resources, climate change affects their livelihoods. Based on climate perception data obtained from 200 households, in 4 villages using household surveys, 12 focus group discussions and meteorological data for the period 1990 to 2020, this study examined local perception of climate change, forest vegetation resources and the various climate adaptation strategies in the Mount Cameroon Region. Results showed 73.4%, 37.3% and 68.8% of the respondents had observed an increase in temperature, rainfall and windspeed, respectively. Mean annual rainfall decreased by 1.0541 mm per year while, the mean annual temperature increased by 0.0263°C per year. This study will help policy makers educate local surrounding forest communities on climate adaptation measures, impacts, and the sustainable use of forest vegetation resources.
