Which of the following is a major concern associated with acid precipitation?

Acid precipitation, commonly known as acid rain, is primarily a concern because it leads to the deterioration of water quality. When acid rain falls, it can lower the pH of lakes, rivers, and streams, making the water more acidic. This increase in acidity can harm aquatic ecosystems, negatively affecting the organisms that live in these habitats, such as fish and amphibians. Some species may not survive the altered conditions, leading to decreased biodiversity and disrupted food chains.

In addition to direct impacts on aquatic life, acid precipitation can also contribute to the leaching of harmful metals such as aluminum from soil and rocks, which further degrades water quality and can be toxic to aquatic organisms. Hence, the connection between acid rain and the deterioration of water quality is a significant environmental concern, as it impacts ecosystems, biodiversity, and even human water supplies.
