this is one of the six criteria air pollutants in the United States?
sulfur dioxide
Bioaccumulation
the build up of a substance (usually a toxin) as it passes through a food chain
What is a solid fuel and what solid fuels are used for cooking and heating?
the household combustion of biomass or coal(WHO). Solid fuels that are used for cooking and heating include: dung, charcoal,wood, crop residue, and coal.

What are 10 things you can do to protect yourself from Unhealthy Air?
1. Check daily air pollution forecasts in your area. Download the American Lung Association's State of the Air app on your mobile device through the GooglePlay app •Avoid exercising outdoors when pollution levels are high. When the air is bad, walk indoors in a shopping mall or gym or use an exercise machine. Limit the amount of time your child spends playing outdoors if the air quality is unhealthy. •Always avoid exercising near high-traffic areas. Even when air quality forecasts are green, the vehicles on busy highways can create high pollution levels up to one-third mile away.• Use less energy in your home. Generating electricity and other sources of energy creates air pollution. By reducing energy use, you can help improve air quality, curb greenhouse gas emissions, encourage energy independence and save money! Check out the U.S. Environmental Protection Agency's easy tips for conserving energy at home. •Encourage your child's school to reduce exposure to school bus emissions. To keep exhaust levels down, schools should not allow school buses to idle outside of their buildings. Many school systems are using the U.S. EPA's Clean SchoolBus Campaign to clean up these dirty emissions. •Walk, bike or carpool. Combine trips. Use buses, subways, light rail systems, commuter trains or other alternatives to driving your car. •Don't burn wood or trash.Burning firewood and trash are among the major sources of particle pollution (soot) in many parts of the country. •Use hand-powered or electric lawn care equipment rather than gasoline-powered. Old two-stroke engines like lawnmowers and leaf or snow blowers often have no pollution control devices. They can pollute the air even more than cars, though engines sold since 2011 are cleaner. •Don't allow anyone to smoke indoors and support measures to make all public places tobacco-free.• Get involved. Start by checking out Fighting for Air which has more information about what you can do.

What is the difference between a secondary and primary air pollutant
A primary air pollutant is emitted directly from a source, such as the emission of nitrogen oxides from diesel engines. A secondary air pollution is formed from a chemical reaction between other air pollutants, such as the formation of ozone from nitrogen oxides and volatile organic compounds. Secondary air pollutants are not directly emitted.

What percentage of the world population uses solid fuels for cooking and heating their homes?

How is indoor air pollution associated with the World Health Orga nization's Millennium Goals?
Reducing the number of people who rely on biofuel and introducing improved energy services is a stepping stone towards achieving the Millennium Development Goals. Improved energy services can reduce child mortality rates, improve maternal health, reduce the time and transport burden on women and young girls, and lessen the pressure on fragile ecosystems.
