Question

which air pollutant has the most affect on people who have heart disease?

o particulate matter

o carbon monoxide

o ozone

o pollution

Explanation:

Particulate matter (PM) can enter the bloodstream and cause inflammation, oxidative stress, and endothelial dysfunction. These effects can exacerbate heart disease by increasing the risk of arrhythmias, heart attacks, and strokes. Carbon monoxide binds to hemoglobin, reducing oxygen transport, but its impact on heart disease is more acute. Ozone mainly affects the respiratory system. "Pollution" is a broad term, not a specific pollutant.

Answer:

particulate matter
