Threats:
Major Threats
Urbanisation at Pool Malebo (Stanley Pool) forms a problem in the region through sewage cast and lead toxicity, mainly coming from car oil and a lot of boat traffic. Marine transport and oil disposal by boats and Matadi pose threats in the region. When the water falls, oil remains on the bottom. Aluminium mining on the land close to the coast in the future could pose problems if water enters the river. This project is however depended for its electricity demand on the success of Inga 3, which will be built in five years. Inga 1 and 2 are existing dams on the Lower Congo with a minimal impact. Inga 3 will divert a significant amount of flow. Grand Inga will block a great part of the mainstream with major impact. Given the restricted mainstream habitat and mainstream impacts such as pollution, it can be threatened in the future by mining in the Luozi region. The key component of concrete is found in this region, and there is potential to mining in the area.
