Which pollutants are examples of short-range primary pollutants?

Primary pollutants are those that are emitted directly from a source and can have immediate effects on air quality and health. Short-range primary pollutants typically affect areas close to their emission sources.

Total suspended solids (TSS) consist of particulate matter that can come from various sources such as dust, smoke, and vehicle emissions. They have significant short-range effects as they can lead to respiratory problems and other health issues in populations nearby.

Sulfur dioxide is a key short-range primary pollutant that primarily results from the burning of fossil fuels, industrial processes, and volcanic eruptions. It can contribute to respiratory illness and can react in the atmosphere to form secondary pollutants, such as acid rain, but is itself a primary pollutant with short-range impacts.

Both of these pollutants are associated with immediate environmental and health consequences in areas close to where they are produced, making them examples of short-range primary pollutants. The other options contain pollutants like ozone and acid rain, which are typically secondary pollutants, as they are formed through chemical reactions in the atmosphere rather than being emitted directly from a specific source.
