Air Toxics Questions and Answers

Questions and answers about air toxics and the Delaware Air Toxics Assessment Study (DATAS). Toxic air pollutants, also referred to as air toxics or hazardous air pollutants (HAPs), are chemicals that, at sufficient concentrations and exposures, are known or suspected to cause cancer. HAPs can also

Federal law requires states to prepare implementation plans to reduce the pollutants that can cause haze in important scenic areas. Delaware was determined to have an impact on haze only for the Brigantine

Particulate Matter

Tiny airborne particles found in haze, smoke and airborne dust, and known as “particulate matter” and usually abbreviated as PM2.5, can occur year-round and can cause serious health problems. Delaware monitors for particulate matter at sites around the state, and works with local governments and other partners in the Delaware Particulate Matter Advance Program to reduce

Ozone

Ozone is a colorless, naturally occurring gas found in two layers of the atmosphere. In the upper layers of the atmosphere, ozone protects life on Earth by absorbing some of the sun’s ultraviolet rays. In the layer closest to the ground, however, ozone is an air pollutant that is a key ingredient of smog and

Air Toxics

Toxic air pollutants, also referred to as air toxics or hazardous air pollutants (HAPs), are chemicals that, at sufficient concentrations and exposures, are known or suspected to cause cancer. They can also cause other serious health problems or cause adverse environmental effects. DNREC monitors Delaware’s air for air toxics and publishes regular Air Toxics Strategic Plans
