Provide teacher workshops to facilitate student air quality education. Conduct air quality demonstrations to students of all ages. Work with transportation planners to coordinate efforts towards reduced traffic congestion and improved air quality. The levels of air pollutants are categorized as good, moderate, and unhealthful. Nitrogen dioxide, and sulfur dioxide levels consistently fall within the good range, the remaining two pollutants often are measured in the moderate range.
Carbon monoxide is an odorless, colorless, poisonous gas emitted in motor vehicle exhaust.
Carbon monoxide levels tend to be higher in the winter because of stagnant air conditions. Ground-level ozone is formed by the reaction of sunlight with motor vehicle exhaust and other pollutants. Ozone levels tend to be higher in the summer when we have more hours of sunlight. Particulate matter consists of small particles, such as soot and dust, that come from motor vehicle emissions, tire and brake wear, earth-moving activities, fireplaces, and dust from unpaved surfaces. Particulate matter levels tend to be high during hot and dry times of the year.
