Which of the following is NOT one of the five main hazardous materials considered in the Convention?

• A. Hydrocarbons
• B. Heavy metals
• C. Asbestos
• D. Plastics

Answer: (D)

The question tests your understanding of which material classes are treated as the main hazardous categories in the convention’s framework. In that framework, the primary groups singled out for special handling and regulation include substances like hydrocarbons (oil and fuel products), heavy metals (such as lead or mercury), and asbestos, along with other highly regulated persistent pollutants. Plastics, while they can pose environmental and health concerns in particular contexts (e.g., additives, microplastics, or contaminated waste), are not listed as one of the five main hazardous material categories in this convention. So plastics isn’t considered one of the core five hazardous material groups, which is why it’s the correct choice for “NOT one of the five main hazardous materials.”
