Secondary standard: A pollution limit set by the EPA for a criteria pollutant and based on environmental effects such as damage to property, plants, visibility, etc.

Smog: A mixture of pollutants, principally ground-level ozone, produced by chemical reactions in the air. Smog can harm health, damage the environment, and hinder visibility. Major smog occurrences are often linked to heavy motor vehicle traffic, sunshine, high temperatures, and certain other weather conditions. Smog may develop far from the source of smog-forming chemicals (such as volatile organic compounds), since the chemical reactions that cause smog occur high in the air, as the prevailing winds carry the reacting chemicals from their sources.

Spina Bifida (without Anencephaly): The most common birth defect in the United States. It is a type of neural tube defect. The neural tube is a narrow channel that folds and closes during the third and fourth weeks of pregnancy to form the brain and spinal cord. Spina bifida happens if the portion of the neural tube that forms the spinal cord does not close completely during the first month of pregnancy.
