The latest news about the dust that plagues the planet comes as copper mining companies have been ordered to stop using copper fungicides.
In December, the United States Environmental Protection Agency (EPA) ordered three mining companies to stop adding copper dust to their copper mining operations and to start using the fungicides in the first quarter of next year.
The copper dust is the main cause of the copper pollution, which causes serious illness in humans, animals and the environment, and the EPA has ordered the companies to switch to the less toxic copper chloride.
However, the company has continued to use copper chloride, which has not been approved by the EPA for use in the United Kingdom, and it is still spraying copper dust on its copper mining facilities.
The EPA has been asked to make a recommendation on whether or not copper dust should be banned in the US as part of a wider environmental assessment of copper mining practices.
Copper dust is a chemical compound made up of copper and nickel that is released by the mining industry when the mining process breaks down copper.
Copper can also be produced by burning copper, so it is usually used as a mining product.
It is used to extract copper and other metals from rock, ore and other minerals.
Coppers have long been used in the construction industry as an abrasive, but the EPA recently stopped using the compound in the U.S. due to concerns that the compound could be toxic to workers and the public.
The EPA said that the use of copper chloride has been in place for over a century, but that it is time to phase it out.
Since the EPA banned copper dust, it has been used on copper sheet metal in some places, but it has not spread to the entire industry.
Earlier this month, the EPA also ordered a halt to the use by all American mines of copper dust as a fire pit cleaning agent.
