Occupational and Environmental Health: Recognizing and Preventing Disease and Injury - Multiple Choice Questions - Learn & Prevent

What principle does the Pollution Prevention Act (PPA) of 1990 emphasize as the national policy?

1. Eco-labeling and mandatory recycling of vehicles

2. Pollution should be prevented or reduced at the source whenever feasible

3. Establishing uniform procedures for the registration and evaluation of chemicals

4. Providing information on the nature and identity of chemicals used at commercial facilities

The correct answer is: Pollution should be prevented or reduced at the source whenever feasible

The Pollution Prevention Act (PPA) of 1990 emphasizes the principle that pollution should be prevented or reduced at the source whenever feasible. This means that efforts should be made to minimize or eliminate the production of harmful substances before they are released into the environment. Options A, C and D are incorrect because they focus on specific actions or procedures rather than the overall principle of prevention. Eco-labeling and mandatory recycling may be helpful in reducing pollution, but they do not directly address the source of pollution. Establishing uniform procedures and providing information on chemicals simply promote transparency and safety, but do not prioritize prevention.
