The refining of Gold.
Firstly a barometer does not use mercury to measure atmospheric pressure.Secondly you need to have a license to handle mercury since it is a very dangerous material.Some barometers do use mercury, but not to directly measure the atmospheric pressure. It was used because air did not mix with the mercury because of the density.So the air would "push down" on the mercury, pushing it up another tube that had a measuring system on it, usually metric.This is where we get the pressure unit Torr, which is 760mmHg, which is 1 ATM (atmosphere), the pressure at sea level.
An important source of particles in the atmosphere is human activities, such as burning fossil fuels, industrial processes, and agriculture. These activities release pollutants like soot, dust, and chemicals into the air, contributing to air pollution and affecting air quality.
Chemicals are everywhere. air, liquids, solids, rocks are all chemicals. If your question is where to buy a specific chemical, then the answer would be to go to one of the chemical suppliers such as Sigma Aldrich or Alfa Aesar.
Mercury does not have any air. It is too close to the sun to have the kind of atmosphere that we have on Earth.
The abiotic factors of the ecosystem include things like the dirt, water, and air. Fracking is a procedure that uses numerous chemicals to release buried shale gas. It is possible that the chemicals used will contaminate the abiotic factors making it impossible for wildlife to survive in these areas.
there is no air

The problems with incinerating waste is that it pollutes the air with many chemicals such as dioxins, lead, cadmium, mercury and fine particles.
Yes, as like in a cigarette the chemicals are release in its fumes and secondary smoking occurs, so other will breathe the air.
Technology can help by improving waste management practices such as recycling and solidification of hazardous waste. Implementing advanced pollution control technologies in waste treatment facilities can minimize the release of hazardous chemicals into the air. Additionally, investing in research and development for alternative waste treatment methods like thermal treatment or chemical conversion could provide more sustainable solutions for hazardous waste disposal.
The three stages of atmospheric transport of chemicals are emissions, dispersion, and deposition. Emissions refer to the release of chemicals into the atmosphere, dispersion involves the movement and distribution of these chemicals in the air, and deposition is the settling of the chemicals onto surfaces on the Earth's surface.
CO,SO2and other like CFC etc causes air pollution.
Pollution is the release of environmental contaminants. The major forms of pollution include: *Air pollution, the release of chemicals and particulates into the atmosphere.
it is caused by humans cars and other thing like chemicals

When frozen mercury looks like an ordinary silver-colored metal. Because frozen mercury is very cold layer of frost may form on it when it is exposed to air.
barometers with mercury measure air pressure. when the air pressure is high the mercury rises
