In which context is acid rain specifically a concern?

Acid rain is specifically a concern in relation to the emissions of sulfur oxides (SOx) and nitrogen oxides (NOx). When these pollutants are released into the atmosphere, they can react with water vapor, oxygen, and other chemicals to form sulfuric and nitric acids. These acids can then fall to the ground as acid rain, which can have detrimental effects on natural ecosystems, water bodies, soil, and even human-made structures.

In this context, the link between acid rain and the emissions of SOx and NOx underscores the importance of regulating these pollutants to mitigate their environmental impact. Urban areas may experience higher levels of these emissions due to industrial activities and vehicle exhaust, but the specificity of concern regarding acid rain centers on how these emissions lead to its formation, rather than solely on where they occur.

The mention of agricultural settings does not specifically encapsulate the broader concern of acid rain, as its effects can be felt in various ecosystems and environments, making it a wider issue than just agriculture. Hot weather can exacerbate pollution but isn’t a direct catalyst for acid rain itself.
