Nitrogen Oxides (N2) correct answers ___________: These are highly reactive gases formed when the heat of combustion initiates reactions between atmospheric nitrogen (N2) and oxygen (O2). Sulfur Dioxide (So2) correct answers ___________: This is a colorless, corrosive gas that damages both plants and animals. Ambient Air correct answers This is the air around us. Non-point Source correct answers Fugitive, or __________, emissions are those that do not go through a smokestack. Criteria Pollutants correct answers Amendments to the law in 1970 designated new standards, to be applied equally across the country, for six major pollutants: sulfur dioxide, nitrogen oxides, carbon monoxide, ozone (and its precursor volatile organic compounds), lead, and particulate matter. These six are referred to as _____________. Carbon Monoxide (CO) correct answers ___________: This is less common but more dangerous than the principal form of atmospheric carbon, carbon dioxide (CO2). Photochemical Oxidants correct answers ___________: These are compounds created by reactions driven by solar energy and atmospheric acids are probably the most important secondary pollutants. Aerosols correct answers ___________: These are extremely minute particles or liquid droplets suspended in the air, are included in this class. Particulate Material correct answers ___________: This includes dust, ash, soot, lint, smoke, pollen, spores, algal cells, and many other suspended materials. Primary Pollutants correct answers ___________: These are substances that are harmful when released. Ozone (O3) correct answers ___________: This is important in the upper atmosphere, where it shields us against ultraviolet radiation from the sun. Hazardous Air Pollutants (HAPs) correct answers Called __________________, these chemicals cause cancer and nerve damage as well as disrupt hormone function and fetal development. Controlled Study correct answers By comparing a treatment (exposed) group and a control (unexposed) group, you have also made this a _________.
