Beyond naturally occurring uranium, mining, phosphates in agriculture, weapons manufacturing, and nuclear power are anthropogenic sources of uranium in the environment. [ 1 ] In the natural environment, radioactivity of uranium is generally low, [ 1 ] but uranium is a toxic metal that can disrupt normal functioning of the kidney, brain, liver ...
Although the New Mexico Environmental Improvement Division said the spill's "short-term and long-term impacts on people and the environment were quite limited", [24] ponds of uranium-contaminated water lined the Puerco River and seeped into wells. United Nuclear denied claims that the spill caused livestock deaths, even though the Navajo ...
In the case of uranium mines, these radionuclides can leach into the water and cause the radioactivity to be carried elsewhere, as well as form precipitates that can be harmful to the environment. The uranium radionuclides can eventually be carried to fruits and vegetables via contaminated waters. Sulfuric acid, oxidation, and alkaline leaching ...
The Uranium Mill Tailings Remedial Action (UMTRA) Project was created by the United States Department of Energy (DOE) to monitor the cleanup of uranium mill tailings, a by-product of the uranium concentration process that poses risks to the public health and environment. The Uranium Mill Tailings Radiation Control Act passed by Congress in 1978 ...
The lifecycle of mining coal is one of the filthiest cycles that causes deforestation due to the amount of toxins, and heavy metals that are released soil and water environment. [85] Although the effects of coal mining take a long time to impact the environment the burning of coals and fires which can burn up to decades can release flying ash ...
The product is a powder of unenriched uranium, "yellowcake," which is sold on the uranium market as U 3 O 8. Uranium mining can use large amounts of water—for example, the Roxby Downs Olympic Dam mine in South Australia uses 35,000 m 3 of water each day and plans to increase this to 150,000 m 3 per day.

The presence of radioactive waste in the environment may cause long-term effects due to the activity and half-life of the radionuclides, leading their impact to grow with time. [2] These particles exist in various oxidation states and are found as oxides , coprecipitates , or as organic or inorganic complexes, according to their origin and ways ...
Absent much environmental regulation prior to the founding of the Environmental Protection Agency in 1970 and passage of related laws, the mining endangered thousands of Navajo workers, as well as producing contamination that has persisted in adversely affecting air and water quality, and contaminating Navajo lands.
