What is the powerful poisonous agent that impairs lung function?

The correct response to identify a powerful poisonous agent that impairs lung function is ozone. Ozone, particularly at ground level, is a significant air pollutant formed by the reaction of sunlight with pollutants such as volatile organic compounds and nitrogen oxides. Exposure to elevated levels of ozone can lead to a range of health issues, particularly respiratory problems. It can cause inflammation of the airways, exacerbate asthma symptoms, and decrease lung function, especially in vulnerable populations such as children and those with preexisting respiratory conditions.

While carbon monoxide is also a harmful gas that can impair oxygen delivery in the bloodstream and hydrogen sulfide is toxic and can affect the respiratory system, ozone is specifically known to directly impair lung function due to its effects on respiratory health. Particulate matter, although harmful and capable of causing various health issues, particularly cardiovascular and pulmonary diseases, does not act in the same way as ozone regarding immediate lung function impairment and is not classified as a single gas that specifically targets lung function.
