Question

particulate matter released during manufacturing that does not change form in the atmosphere is considered to be primary pollutants from a stationary source primary pollutants from a mobile source secondary pollutants from a stationary source secondary pollutants from a mobile source question 4 (true/false worth 1 points) (04 03r lc) an urban area may reduce air pollution if more people give up using certain cars individually for buses or trains. true false

Explanation:

1. For the first question, primary pollutants are emitted directly into the atmosphere in a harmful form. Manufacturing is a stationary source. So particulate matter released during manufacturing that doesn't change form is primary pollutant from a stationary source.
2. For the second question, public - transportation like buses and trains are more energy - efficient and emit less per passenger than individual cars. So giving up individual car use for public transport can reduce air pollution in urban areas.

Answer:

1. primary pollutants from a stationary source
2. true
