Quizplus · Accepted Answer

Ambient standards, which are regulations that set limits on the concentration of pollutants in the outside air, water, or ground, cannot be enforced directly because they target the quality of the environment rather than specific sources of pollution. Enforcement must instead focus on controlling emissions from various sources to ensure that the ambient standards are met.
