The Stockholm Convention on Persistent Organic Pollutants was adopted at a Conference of Plenipotentiaries on May 22, 2001, in Stockholm, Sweden, and went into effect on May 17, 2004. The Stockholm Convention on POP attempts to prevent or limit the usage of and creation of persistent organic pollutants (POPs). This article will explain to you about the Stockholm Convention On POP which will be helpful in preparing the Environment Syllabus for the UPSC Civil Service exam.

Why are POPs harmful?

• POPs are present practically everywhere today, including in our food, soil, air, and water.
• POP levels in humans and animals all throughout the world are at or very close to those that potentially harm them.
• POPs provide a specific risk due to four characteristics: they are toxic, persistent, and accumulate in the body fat of people, marine mammals, and other species, where they are transferred from mother to fetus.
• POPs accumulate in living organisms through a process known as bioaccumulation.
• POPs are not soluble in water, but they are readily absorbed in fatty tissue, where concentrations can be magnified up to 70,000 times higher than the background levels.
• Additionally, POPs can move considerable distances on wind and water currents.
• POPs can cause cancer, immune system diseases, reproductive and developmental problems, and nervous system damage in both human and animal tissue even in small concentrations.

Stockholm Convention on POP - History

• The United Nations Environment Programme (UNEP) Governing Council urged for international action on POPs in 1995.
• The article characterized POPs as "chemicals that remain in the environment, bio-accumulate through the food web, and represent a danger of generating harmful impacts to human health and the ecosystem."
• After that, the "dirty dozen"—a list of the 12 worst offenders—were evaluated by the Intergovernmental Forum on Chemical Safety (IFCS) and the International Programme on Chemical Safety (IPCS).
• The Stockholm Convention on POPs was accepted by delegates during the Conference of the Plenipotentiaries held from May 22–23, 2001 in Stockholm, Sweden.
• The Convention's negotiations came to an end in Stockholm on May 23, 2001.
• With the approval of the convention by the first 128 parties and 151 signatories, it came into effect on May 17, 2004.

Stockholm Convention on POP - Objectives

• To put POPs control measures in place.
• To create and carry out action plans for substances created accidentally.
• To create inventories of the stockpiles of chemicals.
• To reevaluate and revise the national implementation plan.
• To continue to report on the new chemicals.
• To incorporate new compounds into the plan for the effectiveness assessment.

Stockholm Convention on POP - Three Annexes

The Stockholm Convention has three annexes that specify which POPs are banned, regulated, and whose unintended production would be curbed:

• Annex A: The member states are required to eradicate the chemicals mentioned in Annex A (There are a few exceptions).
• Annex B: The use of the chemicals mentioned in Annex B is strictly prohibited (subject to exception).
• Annex C: Unintentionally created substances are to be decreased with actions aimed at eventual eradication under this annexure, according to Annex C.

Stockholm Convention - Listed Substances (POPs)

Initially, twelve POPs were identified as having negative effects on humans and the environment, and these can be classified into three categories:

Stockholm Convention - Newly Proposed Substances

• The CoP adopted amendments to Annexes A, B, and C of the Stockholm Convention at its fourth meeting in 2009, listing nine new persistent organic pollutants.
  • Pesticides used include chlordecone, alpha hexachlorocyclohexane, beta hexachlorocyclohexane, lindane, and pentachlorobenzene.
  • Industrial chemicals include hexabromobiphenyl, hexabromodiphenyl ether, and heptabromodiphenyl ether, as well as pentachlorobenzene, perfluorooctane sulfonic acid, its salts, and perfluorooctane sulfonyl fluoride, tetrabromodiphenyl ether, and pentabromod
  • Alpha hexachlorocyclohexane, beta hexachlorocyclohexane, and pentachlorobenzene are byproducts.
• At its fifth meeting in 2011, the CoP amended Annex A of the Stockholm Convention to include a specific exemption for technical endosulfan and its related isomers.
• In 2017, the COP updated the Stockholm Convention to include 16 additional chemicals.
• The 16 new compounds under the Stockholm Convention are listed as follows:
  • Alpha hexachlorocyclohexane
  • Pentachlorobenzene
  • Beta hexachlorocyclohexane
  • Pentachlorophenol and its salts and esters.
  • Chlordecone
  • Perfluorooctane sulfonic acid (PFOS), its salts and perfluorooctane sulfonyl fluoride (PFOSF).
  • Hexabromobiphenyl
  • Polychlorinated naphthalenes
  • Hexabromocyclododecane
  • Technical endosulfan and its related isomers
  • Hexabromodiphenyl ether and heptabromodiphenyl ether (commercial octabromodiphenyl ether)
  • Tetrabromodiphenyl ether and pentabromodiphenyl ether (commercial Pentabromodiphenyl ether)
  • Hexachlorobutadiene
  • Decabromodiphenyl ether (Commercial mixture, cDecaBDE)
  • Lindane and
  • Short-chain chlorinated paraffins (SCCPs)

Stockholm Convention and India

• The Stockholm Convention includes India as a party. India ratified the international agreement in May 2002, and it came into effect in January 2006.
• The Energy and Resources Institute (TERI) January 2018 report on POPs in Indian Environment states that improper management of e-waste and municipal and industrial wastes is to blame for the high level of POPs in Indian environment.
• Due to the Stockholm Convention (SC), India is exempt from the DDT prohibition and is permitted to produce and use DDT, but only for the prevention of vector-borne diseases.

Significance

• India is committed to upholding its duties under international environmental and human health treaties, as evidenced by the Cabinet's acceptance of POPs.
• Additionally, it demonstrates the government's determination to combat POPs by putting control measures into place, creating and implementing action plans for chemicals generated accidentally, creating inventories of the chemicals' stockpiles, and conducting reviews.
• India would be eligible to use financial resources from the Global Environment Facility (GEF) after the ratification procedure.

Conclusion

In order to gradually reduce the amount of persistent organic pollutants in the environment, the Stockholm Convention was thus created as a legally binding international agreement. The Convention's Article 16 mandates that the effectiveness of the measures it has adopted be assessed on a regular basis. Although some critics have claimed that the treaty is to be responsible for the ongoing death toll from malaria, the treaty actually clearly authorized the use of DDT for mosquito control in the interest of public health.

GS Mains Questions and Model Answers

Q1: Evaluate the significance of the Stockholm Convention in the context of global environmental governance.

Answer: The Stockholm Convention plays a pivotal role in global environmental governance by addressing the dangers posed by persistent organic pollutants (POPs), which have harmful impacts on human health, wildlife, and ecosystems. POPs are highly toxic and can travel long distances across borders, making international cooperation essential for effective regulation. By setting legally binding controls on the production, use, and disposal of POPs, the Stockholm Convention provides a framework for member countries to work together towards the global reduction of these pollutants. Through its emphasis on the elimination of hazardous chemicals, promotion of safer alternatives, and sharing of technical expertise, the Stockholm Convention helps protect environmental sustainability, public health, and biodiversity. It also fosters a sense of global responsibility and supports developing countries with the necessary resources and knowledge to comply with environmental standards.

Q2: Discuss the challenges in the implementation of the Stockholm Convention, particularly in developing countries.

Answer: The implementation of the Stockholm Convention faces several challenges, particularly in developing countries. One of the key challenges is the lack of technical expertise and infrastructure to monitor and control the presence of POPs. Developing countries often lack the resources to properly dispose of hazardous waste and manage the environmental remediation of contaminated sites. Additionally, there may be resistance to the phasing out of POPs due to their perceived economic benefits, such as in the case of pesticides used in agriculture. The financial burden of transitioning to safer alternatives can also be a significant hurdle for low-income countries. International cooperation and financial assistance, therefore, play an essential role in addressing these challenges and ensuring that all countries, particularly those in the developing world, can meet the obligations set out in the convention.

Q3: What role does scientific research play in the effective implementation of the Stockholm Convention?

Answer: Scientific research is crucial in the effective implementation of the Stockholm Convention as it provides the foundation for understanding the behavior, toxicity, and environmental persistence of POPs. Ongoing research helps identify new POPs that may not yet be regulated and aids in assessing the effectiveness of existing control measures. Research also supports the development of safer alternatives to POPs and facilitates the creation of environmentally sound methods for their disposal. Scientific data on the global distribution of POPs and their impacts on human health and ecosystems informs policy decisions and helps countries to prioritize actions. Furthermore, research enables the monitoring of POP levels in the environment, ensuring that control measures are working effectively and contributing to global efforts to reduce pollution.
