Which of the following is NOT a problem associated with acid deposition?

The impact of acid deposition, commonly known as acid rain, encompasses several environmental issues, but it does not significantly pose a direct risk to human health through skin contact. While acidic substances can indeed irritate skin upon direct contact, the primary concerns with acid deposition focus on its effects on ecosystems, infrastructure, and soil rather than on human bodies.

Negative impacts of acid deposition mainly include alterations in aquatic ecosystems where increased acidity can harm fish populations and aquatic life. It also leads to corrosion of buildings and monuments, especially those made of limestone and marble, due to the reaction between the acid and the minerals. Adverse effects on soil quality arise when crucial nutrients are leached away, affecting plant growth and ecosystem health. These consequences highlight the environmental significance of acid deposition rather than any acute health-related effects stemming from contact with human skin.
