Air Quality and Noise Flashcards
The most likely cause of photochemical smog is due to
Heavy motor vehicle traffic
The industries least likely to be a source of sulfur dioxide pollution are
Hazardous waste incinerators
Scrubbers are wet collectors generally used to remove particles that form as a
Fog, mist, or dust
Particle size selective inlets are used to separate particulates above and below 2 to 3 microns in size on
High-volume samplers
The most common type of noise measurement device used for initial inspections is the
Sound level meter
When two pollutants are combined, the effects are greater than the sum of the individual effects. This is called
Synergism
