Question

Sarah has asthma and lives in a big city with a lot of traffic. Sometimes, pollution in the air outside makes it difficult for her to breathe. Which type of pollution is associated with emissions from cars on the highway?"

Answer 1

The pollution associated with car emissions contains nitrogen oxides, carbon monoxide, and particulate matter, which contribute to the formation of smog and can exacerbate asthma symptoms.

Step-by-step explanation:

The type of pollution associated with emissions from cars on the highway is primarily outdoor air pollution including harmful pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), particulate matter (PM), and hydrocarbons which are byproducts of fuel combustion. These pollutants contribute significantly to the formation of smog, which commonly affects urban areas with heavy traffic. Given Sarah's condition of asthma, she should be particularly cautious as these pollutants can exacerbate her respiratory issues.

Motor vehicle emissions are a notable source of urban air pollution, giving rise to various health problems including respiratory diseases such as asthma, heart and lung diseases, and even cancer. To better protect her health, Sarah may need to monitor the Air Quality Index (AQI) and limit her outdoor activities when the levels of air pollution are high.
