Question 1: What is the main difference between a "hazardous waste" and a "universal waste" in the context of hazardous materials management?

Which action should you take?

Choose only one option

Universal waste is only generated in specific industries

Hazardous waste is not recyclable, while universal waste can be recycled

Universal waste is more hazardous than hazardous waste

Hazardous waste is toxic, flammable, or reactive, while universal waste is commonly generated and has less stringent regulations

Question 4: In an EIA, how is the "significance" of an environmental impact determined?

Which action should you take?

Choose only one option

By considering the financial benefits of the project

By evaluating the potential magnitude, duration, and reversibility of the impact

By comparing the project to similar projects in the region

By calculating the total cost of the project

Question 5: What is the primary role of sample digestion in the analysis of hazardous materials?

Which action should you take?

Choose only one option

To break down complex matrices and release analytes

To preserve the stability of volatile substances

To increase the analyte concentration

To remove matrix interference and simplify quantification

Question 6: What is the function of a "blank" in a chemical analysis experiment?

Which action should you take?
