Bauxite mining can pollute the air, water and soil, thus directly affecting the environment. Air pollution The substances produced during the bauxite mining process include dust, sulfur dioxide (SO2), and nitrogen oxides (NOx). The mining and beneficiation of bauxite do not involve the use of chemical reagents and produces no odors.

These are very real and at times severe issues. The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

Various agents, like wind, water, deforestation, overgrazing by cattle, etc., cause soil erosion. The various factors of soil erosion are: 1. Wind. When strong winds blow, the topsoil along with the organic matter is carried away by the wind. This happens more often when the land is not covered with grass or plants.
