Q

The use of sinking and dispersing agents for the removal of surface oil is __________.

🔍 Key Concepts

• Environmental impact of spill response methods (mechanical recovery, burning, dispersants, sinking agents) • U.S. policy and international practice on use of sinking/dispersing agents • Trade‑offs between removing oil from surface vs. effects on marine organisms

💭 Think About

• Ask yourself why some oil‑spill response methods are tightly restricted by regulations—what are authorities trying to prevent? • Think about what happens to oil and chemicals after they leave the surface—where do they go, and who/what is exposed to them? • Compare "removing the visible problem" on the surface with the long‑term impact below the surface. Which is more of a concern for regulators?

✅ Before You Answer

• Review how often chemical sinking/dispersing agents are actually used in U.S. spill response compared to booming and skimming • Consider whether concentrating oil and chemicals in the water column or on the seabed is good or bad for fish, shellfish, and other marine life • Verify whether regulatory and environmental guidance describes these agents as safe or as potentially damaging to ecosystems
