What is one of the risks associated with nonbiodegradable pollutants?

Nonbiodegradable pollutants pose significant environmental risks because they do not break down naturally over time, leading to long-lasting impacts on ecosystems. One of the primary concerns is the contamination of groundwater. These pollutants can leach into the soil and migrate through the subsurface, potentially reaching aquifers and other sources of drinking water. This contamination can jeopardize water quality, harm aquatic life, and pose health risks to humans who rely on this water for consumption and agricultural use.

In contrast, the other choices do not accurately represent the implications of nonbiodegradable pollutants. For example, while reduction of soil fertility can occur due to pollutants, it may not be directly linked to the nonbiodegradability of materials. Increased agricultural yield and improving air quality are generally not associated with nonbiodegradable pollutants, as these pollutants tend to have adverse effects on overall environmental health and agricultural practices, rather than promoting positive outcomes.
