Nya Flashcards
Is a gas for a liquid or solid dispersed through ordinary air released in a big enough quantity.
Air pollution
Coal, petroleum, and other fuels, organic (carbon-based) compounds. When sulfur burns with oxygen from the air, _ is produced. Coal-fire power plants are the world’s biggest source of _ air pollution. It contributes to the smog, acid rain, and health problems that include lung problems
Sulfur dioxide
This highly dangerous gas forms when fuels have too little oxygen to burn completely. It spews out in car exhausts and it can also build up to dangerous levels inside your home if you have a poorly maintainedgas boiler, stove, or fuel-burning appliance.
Carbon monoxide
This gas is central to everyday life and isn’t normally considered a pollutant. However, _ is also a greenhouse gas released by engines and power plants. Since the beginning of the Industrial Revolution, it’s been building up in Earth’s atmosphere and contributing to the problem ofglobal warming and climate change.
Carbon dioxide
Pollutants produced as an indirect result of combustion, when nitrogen and oxygen from the air react together. _ pollution comes fromvehicle enginesand power plants, and plays an important role in the formation of acid rain, ozone and smog.
Nitrogen oxide
These carbon-based chemicals evaporate easily at ordinary temperatures and pressures, so they readily become gases. they’re used as solvents inpaints, waxes, and varnishes. Unfortunately, they’re also a form of air pollution, and have long-term effects on people’s health and also play a role in the formation of ozone and smog.
Volatile organic compounds
These are the sooty deposits. The smaller the particulates, the deeper they travel into our lungs. In cities, most of it comes from traffic fumes.
Particulates
Also called trioxygen, At ground level, it’s a toxic pollutant that can damage health. It forms when sunlight strikes a cocktail of other pollution and is a key ingredient of smog.
Ozone
Three key sources
1.Traffic
2. powerplant
3. industrial plants and factories
There are overone billion cars on the road today. Virtually all of them are powered bygasolineanddiesel enginesthat burn petroleum to releaseenergy.
Traffic
Like vehicle engines, _ produce a range of air pollutants, notably sulfur dioxide, nitrogen oxides, and particulates. (They also release huge amounts of carbon dioxide, a key cause ofglobal warming and climate changewhen it rises and accumulates in the atmosphere.
Power plants
Most plants that pollute release small amounts of pollution continually over a long period of time, though the effects can be cumulative . Sometimes industrial plants release huge of amounts of air pollution accidentally in a very short space of time.
Industrial plants and factories
Can be replenished over short period of time
Renewable resources
Takes millions of years to form an accumulate
Non renewable resources
Any hydrocarbon that can be used as an energy source.
Fossil fuels
