Air Quality and transport
The problem of Air Quality and transport is complex and can be viewed from two perspectives:
- Influence of the transport on the ambient air quality Any existing vehicle has a direct or indirect operational footprint of one of three types: carbon, nuclear or heat. It is obvious for cars, planes or ships powered by internal combustion engines. It is not so clear for “green” electric vehicles, but they are charged by the electricity of mostly fossil or nuclear origin.
- Quality of the air inside the vehicle The internal air in most of the vehicles, except submarines and space ships, is mixed with external ambient air in some proportion. The quality of vehicle internal air depend on the ambient air quality, internal sources of pollution, air exchange rate, air refresh rate, available means of air filtration and regeneration.
The Air Quality and microclimate control techniques in transportation industry has some specific concerns. Let’s take as example marine industry. Marine industry workers on board ships are under unique conditions of work and rest. During their service on board, seafarers live in the environment, where working and leaving quarters are adjacent and their atmospheres interchange at some rate. Harmful substances, which often can be found in the air of working area infiltrate into the air of living premisses. This leads to the permanent exposure to accumulated levels of Carbon Oxide, Sulfur Dioxide, Nitrogen Dioxide, Particulate Matter, various hydrocarbon vapors and other substances which should not be normally found in the breathing air.
