Acid Aerosol

Acid Aerosol

A colloidal suspension of acidic particles that form the "summer haze" generated by SO2 and NO2 emissions from coal-burning power plants.

A MERV of 9 was obtained for both polydisperse oleic acid aerosol tests, while a MERV of 7 was obtained for both polydisperse KCI tests.
But the simulations that factored in the effect of sulfuric acid aerosol particles showed that if fossil fuels were burned, minute solid particles emitted into the air with CO2 would disperse and absorb sunlight and prevent heat from reaching the ground.
These include hydrochloric acid aerosol, sulfuric acid and hydrogen fluoride.
The summer atmospheric chemistry in the South, Husar explains, may be more conducive to rapidly converting sulfur dioxide (a gas) to sulfate (an aerosol), with the ultimate byproduct being acid aerosol. Also, the Southeast is subject to the Atlantic High Pressure System, which keeps warm, muggy air at a standstill for three to five days at a time, holding the witches' brew of sulfur, nitrogen oxides, soot, and particulate matter in place for long periods.

'The CFB does not control many other emissions from a coal plant, including particulate matters and acid aerosols, which cause grave respiratory ailments,' De los Reyes said.
The cooler temperatures happen because the emitted gases (containing sulfur dioxide) mix with water droplets in the atmosphere to form sulfuric acid aerosols. The aerosols reflect sunlight away from the earth.
Copper mining also has a significant negative impact on the environment through particulate matter, sulphur dioxide (SO2), sulphuric acid aerosols and other emissions.

According to the Ministry of Environment, SO2 also causes formation of microscopic acid aerosols, which have serious health implications as well as contribute to climate change.
