Sadly enough, most of us don't even know about this pollution because the effects are not immediately visible. ... For example, our love with automobile has had and will have enormous effects on our air quality. ... Consequently, mobile sources contribute significantly to air pollution. ... On a national scale mobile sources are accountable for nearly 75% of carbon monoxide pollution. ... The hundreds of oil fires that produced unprecedented amounts of pollution were extinguished within six months but became a huge air pollution laboratory; oil spilled onto the ground and into the Gul...

Emissions that are produced by humans are largely responsible for air pollution, climate change, and the increasingly poor health of people around the world. ... In the combustion process and by fuel evaporation, a vehicle takes part in environmental pollution and the greenhouse effect, which ultimately causes global warming. ... Air and fuel are required to fire up an engine. ... The wide band oxygen sensor acts as an air-fuel ratio (AFR) sensor, wide range air-fuel (WRAF) sensor, lean air-fuel sensor, and a general air fuel sensor. ... "Proton exchange membrane fuel cells operating on hydr...

At first glance, this seems like an efficient energy source, but upon closer consideration, it becomes obvious that the cost "pollution--dramatically overshadows the benefits. ... Hydrocarbons, which are toxic and carcinogenic, escape into the air during refueling and running a car engine and cause eye irritation, congestion, wheezing, shortness of breath, permanent lung damage, and acid rain. ... The government demanded strict laws enacted very quickly, but the automobile industry believed they took the wrong approach by focusing solely on automotive pollution and ignoring boat makers, ...

Fuel cells generate electricity through an electrochemical reaction that combines hydrogen with ambient air. ... Battery-powered vehicles give off virtually no pollution and offer one of the best options for reducing motor vehicle emissions in polluted cities. ... But these plants are often in rural areas where the emissions do not drive pollution levels above health standards. ... More efficient cars can make a big difference to society in terms of environmental benefits, and the serious deterioration of urban air has motivated regulators to require cleaner cars. ...

This is due to air drag and other technical issues that deal with cars but the thing is that hybrid cars already have this advantage due to the use of both batteries and gasoline in the car. ... A well designed hybrid can reduce smog pollution by 90% or more compared with the cleanest conventional vehicles on the road today. Hybrid cars burn less gasoline per mile, so they release much less pollution and fewer greenhouse gases unlike gasoline powered trucks and cars being in America. ...

More recently, "biomass fired steam power has been used to generate electricity [which] can have numerous environmental and air-quality advantages over burning fossil fuels" (How Biomass Energy Works"). ... The very nature of biomass energy requires that it be burned and even if the organic material is low-carbon, it will still emit some pollution and carbon emissions. ... Instead, researchers have recently developed a power cell that uses magnesium as a one of the main components called the "Magnesium Air Fuel Cell,"" it is essentially a "magnesium based version of the lithium ion rechargeabl...
