Acidification
About:


Definition:

Acidification

Acidification is caused by acid depositions of three main pollutants: sulfur dioxide (SO2), nitrogen oxides (Nox), and ammonia (NH3).
Acid depositions have negative impacts on water, forests, and soil as well as causing damage to buildings and monuments.
The main sources of emissions of acidifying substances are fossil fuel combustion used for energy production and transport.

The result of acidifying pollutants emissions, such as SO2 or Nox, to the air.
These emissions have negative impacts on soil, groundwater, surface waters, biological organisms, ecosystems and materials.
(GreenSpec AEP ’09)


Acidification is caused by direct outlets of acids or by outlets of gases that form acid in contact with air humidity and are deposited to soil and water.
These acid depositions have negative impacts on natural ecosystems and the man‐made environment including buildings.1

Notes: 

Construction Waste

BRE waste statistics indicate wastage factors of 30% from plasterboard linings, far higher than the 5-20% wastage factors allowed by Standard Methods of Measurement (SMM).

When gypsum or desulferisation gypsum is mixed with biodegradable green waste in landfill, there is a high likelyhood that the biodegradable waste will react with the gypsum and rerelease the chemicals filtered out on its creation, releasing the chemicals to atmoshere and potentiallly to create acid rain.

Gypsum is classified as stable non-ractive hazardous waste which must now be segregated and sent to special landfill site or special cells within landfills.
