Which term denotes substances that, when released, degrade environmental quality?

• A. Nutrients
• B. Pollutants
• C. Detritus
• D. Sediments

Answer: (B)

Substances released into the environment that harm air, water, or soil quality are pollutants. This term captures any material—chemicals, oils, pesticides, heavy metals, plastics, and more—that causes harm to living organisms or disrupts ecosystem processes when it enters the environment. Nutrients, while essential for life, can become problematic in excess and lead to issues like algal blooms, but they aren’t defined by degrading quality. Detritus is dead organic matter that participates in nutrient cycling and decomposition, not inherently harmful. Sediments are particles that can affect water clarity and habitats, but the overarching label for substances that degrade environmental quality when released is pollutants.
