Which chemical outcome escalates when increased soil acidity impairs buffering?

💡 Explanation

Increased acidity accelerates heavy metal solubility; as acidity overwhelms buffering capacity, increased metal ions enter the soil solution; this promotes intensive soil leaching of dangerous materials, because lower pH enhances metal dissolution, therefore mobilization and runoff are more likely, rather than precipitation.
