What are the environmental problems associated with ships, airplanes and trains?

Overall water, gas, sound, slag will be involved to varying degrees, and at the same time accompanied by the consumption of resources and energy.

1 ships: ships are most likely to cause water pollution, may be due to: 1, the ship cleaning (cleaning cabin, etc.) and living water and other untreated discharge into the water column caused by pollution. 2, ship leakage, inland transportation, many ships are powered by diesel, diesel fuel leakage will cause water pollution; more typical is the oil leakage caused by marine pollution, will cause fatal injury to marine organisms. fatal injury to marine life, and the rapid spread of pollution, difficult to control and eliminate.

The combustion of diesel fuel during the operation of ships will emit CO2, SO2, nitrogen oxides and other substances, which will cause atmospheric pollution.

Noise pollution from ships is not a major concern. And solid waste pollution is mainly caused by the ship's maintenance and abandonment process.

2 airplanes:Airplanes are most concerned about the pollution is noise pollution, China's relevant legislation for the construction of airports have clear provisions.

Flight power is provided by aviation kerosene, its combustion process will also emit CO2 and other atmospheric pollutants, but due to the altitude of the aircraft in the troposphere at the top of the lower stratosphere, and we are usually concerned about the atmospheric pollution refers to the troposphere of the pollution, so at present, the aircraft caused by atmospheric pollution is not a major concern. However, as the environmental situation becomes more and more serious, air pollution from airplanes should receive more attention in the future.

3 train: train noise pollution is less than airplanes, but in the construction process must also be taken into account.

The air pollution caused by trains depends on its power system. One of the internal combustion locomotives powered by diesel, will produce CO2, nitrogen oxides and a variety of hydrocarbons caused by air pollution; if the electric locomotive requires the consumption of a large amount of electricity, the operation of the process does not have serious air pollution.

The train another incidental pollution is the travelers thrown out of the train waste caused by solid waste pollution, which is the most notorious along the railroad "white pollution", in recent years there has been a significant improvement.
