Nguồn gây ô nhiễm di động Nguồn điện thoại di động, hay còn gọi là nguồn vận tải, xe cộ, bao gồm xe hơi, xe tải, xe buýt, tàu và máy bay khác nhau. Chất gây ô nhiễm không khí phát ra sẽ khác nhau, tùy thuộc vào nhiên liệu được đốt hoặc phản ứng (trong trường hợp của các tế bào nhiên liệu hoặc pin) và thiết kế động cơ của mỗi chiếc xe. Ô tô phát hiện của ô tô xuất hiện để kết hợp thỏa đáng mong muốn của con người để vận chuyển nhanh chóng với mong. | MOBILE SOURCE POLLUTION Mobile sources alternatively called transportation or vehicular sources include cars trucks buses ships and various aircraft. Air pollutants emitted will vary depending on the fuel being combusted or reacted in the case of fuel cells or batteries and the engine design of each vehicle. THE AUTOMOBILE The automobile s discovery appears to satisfactorily combine a human desire for rapid transportation with the desire for independence and flexibility. However the increasing vehicle population poses a series of threats to continued physical and psychological well-being and to the future of our environment. As the automotive industry expands other auxiliary industries such as petroleum production and concrete and tire manufacturing also grow with additional potential for pollution problems. Additional roads also have to be built with a negative impact on both ecology and landscape. A balance must be made between the right of an individual to use his own car when and where he drives and the harm brought upon society as a whole by his doing so. If it is accepted that society needs to be protected a number of legislative and economic measures can be initiated to discourage automotive usage. Legislation has been enacted to limit the emission of HC hydrocarbons NO. oxides of nitrogen CO carbon monoxide and particulate matter including lead compounds. However other waste materials such as tires and the automobile itself including the repugnant abandoned cars must be disposed of. The broad approach to automotive pollution control is to encourage alternative means of transportation. This would include improvements in mass transit such as high-speed trains moving sidewalks increased links and modernization. In the city bicycle riding and walking are low pollution high exercise alternatives in rural areas car pools might be formed. Cars have been built using different energy concepts ex. battery turbine engine sterling engine and to run on different fuels .
