Question

dust from agricultural processes and construction constitutes what type of air pollution?
nitrogen oxides
suspended particulate matter
ozone
carbon

Explanation:

Dust from agricultural processes and construction are solid particles suspended in the air. Suspended Particulate Matter (SPM) refers to such solid or liquid particles suspended in the air. Nitrogen Oxides are gaseous pollutants (e.g., \(NO\), \(NO_2\)). Ozone (\(O_3\)) is a gaseous pollutant. Carbon can refer to carbon - based gases (e.g., \(CO\), \(CO_2\)) or in some cases, soot (which is a form of particulate matter, but the more general term for dust - like particles from the given sources is SPM).

Answer:

Suspended Particulate Matter
