Question

classifying types of air pollutants
sort the pollutant into its correct category.
coal - burning particulates
waste incinerator gases
carpet dust and dirt
cat litter box
vehicle exhaust
carbon monoxide

Explanation:

• Carpet dust and dirt: Found in indoor environments like homes or offices, contributing to indoor air pollution.
• Cat litter box: Emits odors and potentially allergens within an indoor space.
• Coal - burning particulates: Result from industrial or power - generation processes outdoors.
• Waste incinerator gases: Released during outdoor waste - disposal operations.
• Vehicle exhaust: Produced by cars, trucks, etc., on outdoor roads.
• Carbon monoxide: Can be from both indoor (e.g., faulty heaters in some cases) and outdoor (e.g., vehicle exhaust) sources. But in a general classification context where we assume typical sources: vehicle exhaust (a major outdoor source) and industrial/combustion processes (outdoor for coal - burning and waste incineration) are more strongly associated with outdoor.

Answer:

• Indoor Air Pollutant: carpet dust and dirt, cat litter box.
• Outdoor Air Pollutant: coal - burning particulates, waste incinerator gases, vehicle exhaust, carbon monoxide.
