Because the ozone layer is located high in the atmosphere, people are not directly exposed to it. Ground-level ozone, however, is a health hazard because people breathe it.

- When high levels of VOCs and NOx are present in the air, they can react. When they react in the presence of sunlight and hot weather, ground level ozone forms. There are other factors involved with the formation of bad or ground level ozone, including; cloud cover, wind direction, and low wind speeds. If the weather conditions are conducive, and there are ample amounts of NOx and VOCs, harmful concentrations of ground level ozone can form in the air.

Air Pollution Linked to U.S. Birth Defects Women in areas with more moderate air pollution were twice as likely to have a baby with a serious heart defect. This type of birth defect almost always means surgery before the child is 1 year old. The increased risk of birth defects was seen only in women who breathed bad air during the second trimester of pregnancy. This is the crucial time when the complex structure and function of the heart and other organs develop.

air pollution People experience a wide range of health effects from being exposed to air pollution. Effects can be broken down into short-term effects and long-term effects. Short-term effects, which are temporary, include illnesses such as pneumonia or bronchitis. They also include discomfort such as irritation to the nose, throat, eyes, or skin. Air pollution can also cause headaches, dizziness, and nausea. Bad smells made by factories, garbage, or sewer systems are considered air pollution, too. These odors are less serious but still unpleasant. Long-term effects of air pollution can last for years or for an entire lifetime. They can even lead to a person's death. Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people's nerves, brain, kidneys, liver, and other organs. Some scientists suspect air pollutants cause birth defects. Nearly 2.5 million people die worldwide each year from the effects of outdoor or indoor air pollution.

Ozone Ground-level ozone, commonly known as “smog,” is the major summertime cause of poor air quality in the Bay Area. The Spare the Air Every Day program was created to reduce summertime ozone pollution. Ozone is essentially an unstable molecule made up of three oxygen atoms. It is created in the lower atmosphere by a combination of pollutants called reactive organic compounds and oxides of nitrogen that get “cooked” by the sun’s ultraviolet rays in a photochemical reaction.
