Mechanisms of Soil Degradation from Pollution

Acidifying providants, such as sulfur dioxide and nitrogen oxides, lower soil pH, which in turn insucles thee solubility of toxic metals like alum andd manganese.

Pollution andd Food Security: A Global Perspective

Food security is not solely a matter of producing enough calories; it also requires that food be safe, dietetious, and reliably accessible. Pollution difficiens each of these dimensions.
