MATCH THE DESCRIPTIONS RELATED TO EXPOSURE TO PERSISTENT TOXIC SUBSTANCES TO THE TYPE OF EXPOSURE. Environmental and occupational interventions are important to reduce these substances so that cancer incidence can be reduced 1. Carcinogens 2. Lead 3.

To match the descriptions related to exposure to persistent toxic substances to the type of exposure: 1. **Carcinogens** - Environmental and occupational interventions are important to reduce these substances so that cancer incidence can be reduced. 2. **Lead** - This is a specific type of toxic substance that can have various sources, typically related to occupational exposure (like in construction and painting) as well as environmental sources (like lead in water or soil). 3. **Heavy metals** - These include substances such as mercury, cadmium, and arsenic, which are also a concern in both occupational and environmental exposure contexts. So, the best match for the description provided is: - **1. Carcinogens** - Environmental and occupational interventions are important to reduce these substances so that cancer incidence can be reduced. The other two substances (Lead and Heavy metals) can also be connected to interventions, but the emphasis on cancer incidence is specifically appropriate for carcinogens.
