Exercise: Red List in Action

Scenario: You are a manager at a small manufacturing company that uses chemicals listed on the Red List.

Task:

1. Identify two specific Red List substances used in your company's processes.
2. Research the potential environmental impacts of these substances.
3. Propose two practical actions your company can take to minimize or eliminate the discharge of these substances into the water.
4. Consider the costs and benefits of these actions.

Example:

1. Substances: Mercury (used in a specific process) and Atrazine (used as a pesticide in the manufacturing facility).
2. Impacts: Mercury is highly toxic and bioaccumulates in the food chain, leading to health risks for wildlife and humans. Atrazine can contaminate water sources and harm aquatic organisms.
3. Actions: Implement a mercury-free alternative for the manufacturing process and transition to safer, less toxic pesticides for use in the facility.
4. Costs & Benefits: While implementing these changes might involve initial costs, the long-term benefits include environmental protection, reduced liability, and potential cost savings from safer alternatives.
