What are normal mercury levels in water?
The normal mercury levels in water vary depending on the location, but generally, concentrations of total mercury in freshwater are typically below 2 ng/L (nanograms per liter). However, it is important to note that even low levels of mercury in water can have negative impacts on human health and the environment.
Which human activity has had the greatest impact on increasing mercury levels?
Burning of fossil fuels, such as coal, is the human activity that has had the greatest impact on increasing mercury levels in the environment. When coal is burned, mercury is released into the atmosphere and can then be deposited into bodies of water where it accumulates in fish.
What allows mercury to dissolve in water?
Mercury dissolves in water due to its ability to form amalgamates. The low solubility of elemental mercury in water limits its dissolution, but it can form complexes with other compounds present in water. The dissolved mercury ions form stable complexes, allowing it to dissolve and become dispersed in the water.
How is Mercury filtered out of water?
Better Question: How is mercury separated from water?As it has a lower boiling point than mercury, the water can be evaporated at 100 degrees Celsius (212 degrees Fahrenheit), leaving the mercury behind. Be careful not to continue heating, as it will cause some mercury to evaporate. Alternatively, since mercury is heavier than water, it will sink to the bottom, allowing you to pour the water off the top.
What ppm of Mercury is harmful to humans?
Exposure to mercury at levels as low as 1 ppm can be harmful to humans. Long-term exposure to mercury at levels above 0.1 ppm in drinking water can lead to serious health effects, particularly affecting the nervous system and kidneys. It is important to limit exposure to mercury to prevent adverse health effects.
What are normal mercury levels in water?

What are the current acceptable levels of mercury in drinking water in Canada?
0.001 mg total mercury per Litre
Why do people need to worry about the mercury levels in the water?
because the mercury will weaken your liver making you in general weaker and so you will die
What happens when you add mercury to water?
When mercury is added to water, it does not dissolve or mix with water. Instead, it forms droplets due to its high surface tension and density. Mercury is insoluble in water and exists as separate droplets or beads.
What happens to the water levels in your body when it is cold outside?
Your mum has sex with me.
How does mercury affect our water?
Mercury doesn't really affect our water, it affects and poisons us and other life in the water. It is a poison that interferes with the brain and nervous system.
What happens to the levels of carbon dioxide and water during aerobic exercise compared to their levels when the performer is at rest?
eutrophication
What is the importance of proper waste disposal of vessels?
take for example Mercury. Mercury is found in batteries and lightswitches and many other commonplace items. When disposed of improperly it can affect the levels of mercury in your water supply. Mercury is extremely unsafe in anything more than small quantities. So disposing of chemicals properly helps keep all of us safer in general, not to mention other animals and the environment.

What happens to the water levels in your body when you dance?
Water levels drops when you dance... And that's because its a way of exercise which water is more readily lost .. therefore you feel the need for a drink after :)

What do you do when every time you feed your goldfish they go up to the surface and stay there for ages?
Change the water. This usually happens if the water is low in oxygen levels. There are other problems that may result in this as well.
