P2.2. Explain four different forms of global pollution arising from construction projects.
Air pollution
Construction is one of the most industries which produces air pollution. This is an issue which has been known over years, however in our country; very little has been done to decrease the amount of pollution which is being generated be the construction industry. Air pollution is affecting the whole atmosphere by contaminating and disturbing the natural composition of the air. Air pollution can be done in various ways in the construction industry, and can be in any form such as gasses; including carbon dioxide or any vapors which may leave` permanent damage to the natural cycle of the environment. Construction air pollution comes from a wide variety of sources. Some of the most excessive sources include:
* Building construction;
* Demolition;
* Vehicle or manufacturing exhaust;
* Using machinery on-site.
Air pollution may affect many aspects of the natural environment, the damage which will be caused by the pollution will depend by the concentration of the pollution in the area.
Ozone weakening by CFCs
CFC is an acronym for Chlorofluorocarbons; these are chemicals which are manmade any were used often for HVAC purposes, including:
* Refrigerators;
* Air conditioning;
* Foam products;
* Aerosols.
CFCs have been replaced with substances which harm less the environment, however the damage has already been made as it is known that the ozone layer has been damaged with substances which were used during the years, but CFCs have been major participants of this issue.
Global Warming
Global warming also known as the greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This effect occurs the same way as the heat is trapped in a closed car. On a very hot day, the car gets hotter when it is outside. This is because the heat and light from the sun can get into...
