Which pollutants come from mobile sources

The Diesel Emissions Reduction Program helps to reduce diesel emissions by providing technical support and funding for vehicle and equipment replacement, repowering and retrofitting; installation of idling reduction technologies; and by providing technical and equipment support for in-use testing.

The Vehicle Emissions Inspection and Maintenance Program helps to ensure that Vermont vehicles remain clean throughout their useful lives by requiring annual testing of vehicle emissions control systems and repairs if needed. The Automotive Technician Training Program provides information and training opportunities to automotive technicians to help ensure effective and cost-effective maintenance and repair of vehicle emission control systems.

Diesel Emissions Reduction. Low Emission Vehicle. Mobile Sources. Vehicle Inspection. The rate at which the reactions proceed is related to both temperature and intensity of the sunlight.

Because of this, problematic ozone levels occur most frequently on hot summer afternoons. The majority of these suggested voluntary actions relate to how you drive your vehicle. To help you better understand the significant amount of positive influence that you can have on Arkansas Air Quality, we have provided some interesting information. The Commuter Calculator tool will allow you to perform a cost analysis of your weekly driving routines. By entering a few facts about how many miles you drive, the fuel efficiency of your vehicle and the price of fuel, you are provided with daily, monthly and yearly cost totals.

By carpooling, even with just one other person, the potential financial savings are quickly calculated for you. If you add more members to the car pool, you can increase your savings even more!

The Green Vehicle Guide will help you choose the cleanest and most fuel-efficient vehicle that meets your needs. The EPA website will help consumers make more environmentally-informed choices when purchasing a vehicle. The Green Vehicle Guide lists pollution levels for all recent model year passenger vehicles sold in the United States. Consumers can select a vehicle model, determine how clean it is relative to other vehicles, comparison shop for similar vehicles, and choose the cleanest vehicle that meets their needs.

Air pollution is a difficult concept to grasp. While we often can't see air pollution, automobiles create many different kinds of emissions. Air pollution is often referred to in terms of pounds. You know that air has weight, but how much of a gas is a pound?

If you use your chemistry and math skills to complete this activity, you will be able to provide a interesting visual display to others and help to raise awareness about air pollution.

There are grams in a pound. Most air pollution, harmful gases and particles in the air, affecting national parks is created outside park boundaries. Mobile sources account for more than half of all the air pollution in the United States and the primary mobile source of air pollution is the automobile, according to the Environmental Protection Agency. Stationary sources, like power plants, emit large amounts of pollution from a single location, these are also known as point sources of pollution.

Area sources are made up of lots of smaller pollution sources that aren't a big deal by themselves but when considered as a group can be. Natural sources can sometimes be significant but do not usually create ongoing air pollution problems like the other source types can.

Particle pollution also called particulate matter or PM is the term for a mixture of solid particles and liquid droplets found in the air.

Some particles, known as primary particles are emitted directly from a source, such as construction sites, unpaved roads, fields, smokestacks or fires. Others form in complicated reactions in the atmosphere of chemicals such as sulfur dioxides and nitrogen oxides that are emitted from power plants, industries and automobiles.

These particles, known as secondary particles, make up most of the fine particle pollution in the country. People who live, work or attend school near major roads appear to have an increased incidence and severity of health problems associated with air pollution exposures related to roadway traffic.

Children, older adults, people with preexisting cardiopulmonary disease, and people of low socioeconomic status are among those at higher risk for health impacts from air pollution near roadways.
