Bonga area rivers are known to have high iron concentrations, which can be harmful to aquatic organisms and ecosystems. Studies have shown that these rivers can be polluted with heavy metals due to acidification or other forms of pollution. The concentration of metals in tissues of fish caught from the rivers has also been assessed, with some species showing higher levels of metal concentrations than others One study found that river water with high iron concentration and low pH caused mortality of lamprey roe and newly hatched larvae This highlights the potential dangers of high iron concentrations in rivers, particularly when combined with other forms of pollution.In-lake iron addition has been proposed as a method for lake restoration, but its impact on aquatic organisms and shallow lake ecosystems is still being studied. It is important to monitor the iron concentration in Bonga area rivers and take steps to reduce pollution to protect the health of aquatic organisms and ecosystems. The nickeliferous prospect of Bonga, Burkina Faso is an example of nickel concentration developed by lateritic weathering of Paleoproterozoic ultramafic rocks. This is an interesting geological feature, but it is not directly related to the high iron concentration in Bonga area rivers. In summary, Bonga area rivers have high iron concentrations that can be harmful to aquatic organisms and ecosystems. Monitoring and reducing pollution is important to protect the health of these rivers.
