As of the latest updates, how many POPs are included under the Stockholm Convention?

• A. 12
• B. 29
• C. 45
• D. 100

Answer: (B)

The question is about how the set of POPs under the Stockholm Convention changes over time. The Convention maintains a listed group of persistent organic pollutants, and that list is expanded through decisions by the Conference of the Parties as new chemicals meet the criteria for listing. Because of these updates, the total number of POPs isn’t fixed forever. As of the latest updates, there are 29 substances on the Stockholm Convention list. This total comes from the original 12 POPs plus additional chemicals added in subsequent COP decisions, reflecting ongoing assessment and inclusion of chemicals that are persistent, bioaccumulative, and harmful to health and the environment. The number 29 captures the current, officially recognized count across the listed Annexes that determine whether a chemical is eliminated, restricted, or controlled in unintentional production. So, 29 is the correct figure because the list has grown beyond the original set and current updates place the total at 29.
