If you use Mercury make sure its in a contanned invirment
If you use Mercury make sure it’s in a contained environment.
So you’re not releasing it back in to the streams or dumping out in the ground.
And remember mercury cost money to so it’s in your best interest to not lose or spill any of it.
In panning for gold you can find it naturally or from the big mining that use it in the old days. And did not make sure to use it in a contained environment.
Check your federal and state laws also.
What is mercury and where does it come from?
Mercury is a naturally occurring metal that can be found at very low levels almost everywhere. Many people are familiar with the silvery liquid form of mercury found in thermometers.
If mercury is naturally occurring, why is it a problem?
In nature, mercury tends to be bound up in rocks and soil, widely dispersed, and does not easily enter the food chain. But when humans extract mercury from rocks for various purposes, or burn fossil fuels, it is released into the air and water, where it can enter the food chain more easily and become concentrated in ways that would not typically occur in nature.
What happens to mercury when it enters the environment?
There are two main forms of mercury found in the environment:
Metallic mercury and mercury compounds enter the air from manufacturing processes and from burning coal, garbage and fossil fuels. It also can be released into the environment from natural deposits and volcanic activity.
Methylmercury is produced in water and soil by bacteria. Methylmercury is highly toxic. From sediments in water, it works its way up the food chain through fish to other animals, including humans.
