Summary of provisions

Key elements of the Convention include the requirement that developed countries provide new and additional financial resources and measures to eliminate production and use of intentionally produced POPs, eliminate unintentionally produced POPs where feasible, and manage and dispose of POPs wastes in an environmentally sound manner. Precaution is exercised throughout the Stockholm Convention, with specific references in the preamble, the objective, and the provision on identifying new POPs.


Persistent Organic Pollutants Review Committee

When adopting the convention, provision was made for a procedure to identify additional POPs and the criteria to be considered in doing so. At the first meeting of the Conference of the Parties (COP1), held in Punta del Este, Uruguay, from 2–6 May 2005, the POPRC was established to consider additional candidates nominated for listing under the convention. The committee is composed of 31 experts nominated by parties from the five United Nations regional groups and reviews nominated chemicals in three stages. The Committee first determines whether the substance fulfills POP screening criteria detailed in Annex D of the convention, relating to its persistence, bioaccumulation, potential for long-range environmental transport (LRET), and toxicity. If a substance is deemed to fulfill these requirements, the Committee then drafts a risk profile according to Annex E to evaluate whether the substance is likely, as a result of its LRET, to lead to significant adverse human health and/or environmental effects and therefore warrants global action. Finally, if the POPRC finds that global action is warranted, it develops a risk management evaluation, according to Annex F, reflecting socioeconomic considerations associated with possible control measures. Based on this, the POPRC decides to recommend that the COP list the substance under one or more of the annexes to the convention. The POPRC has met annually in Geneva, Switzerland, since its establishment. The seventh meeting of the Persistent Organic Pollutants Review Committee (POPRC-7) of the Stockholm Convention on Persistent Organic Pollutants (POPs) took place from 10 to 14 October 2011 in Geneva. POPRC-8 was held from 15 to 19 October 2012 in Geneva, POPRC-9 to POPRC-15 were held in Rome, while POPRC-16 needed to be held online.


Listed substances

There were initially twelve distinct chemicals ("dirty dozen") listed in three categories. Two chemicals, hexachlorobenzene and polychlorinated biphenyls, were listed in both categories A and C. Currently, five chemicals are listed in both categories.


Chemicals newly proposed for inclusion in Annexes A, B, C

POPRC-7 considered three proposals for listing in Annexes A, B and/or C of the convention: chlorinated naphthalenes (CNs),
hexachlorobutadiene Hexachlorobutadiene, Cl2C=C(Cl)C(Cl)=CCl2, is a colorless liquid at room temperature that has an odor similar to that of turpentine. It is a chlorinated aliphatic diene with niche applications but is most commonly used as a solvent for other chlo ...

(PCP), its salts and esters. The proposal is the first stage of the POPRC's work in assessing a substance, and requires the POPRC to assess whether the proposed chemical satisfies the criteria in Annex D of the convention. The criteria for forwarding a proposed chemical to the risk profile preparation stage are persistence, bioaccumulation, potential for long-range environmental transport (LRET), and adverse effects. POPRC-8 proposed
hexabromocyclododecane Hexabromocyclododecane (HBCD or HBCDD) is a brominated flame retardant. It consists of twelve carbon, eighteen hydrogen, and six bromine atoms tied to the ring. Its primary application is in extruded (XPS) and expanded (EPS) polystyrene foam that ...
for listing in Annex A, with specific exemptions for production and use in expanded polystyrene and extruded polystyrene in buildings. This proposal was agreed at the sixth Conference of Parties on 28 April-10 May 2013. POPRC-9 proposed di-, tri-, tetra-, penta-, hexa-, hepta- and octa-chlorinated napthalenes, and hexachlorobutadiene for listing in Annexes A and C. It also set up further work on pentachlorophenol, its salts and esters, and decabromodiphenyl ether, perfluorooctanesulfonic acid, its salts and perfluorooctane sulfonyl chloride. POPRC-15 proposed PFHxS for listing in Annex A without specific exemptions. Currently,

Controversies

Although some critics have alleged that the treaty is responsible for the continuing death toll from malaria, in reality the treaty specifically permits the public health use of

). There are also ways to prevent high amounts of DDT consumed by using other malaria vectors such as window screens. As long as there are specific measures taken, such as use of DDT indoors, then the limited amount of DDT can be used in a regulated fashion. From a developing country perspective, a lack of data and information about the sources, releases, and environmental levels of POPs hampers negotiations on specific compounds, and indicates a strong need for research. Another controversy would be certain POPs (which are continually active, specifically in the Arctic Biota) that were mentioned in the Stockholm Convention, but were not part of the Dirty Dozen such as perfluorooctane sulfonate (PFOS). PFOS have many general uses such as stain repellents but have many properties which can make it a dangerous due to the fact that PFOS can be highly resistant to environmental breakdown. PFOS can be toxic in terms of increased offspring death, decrease in body weight, and the disruption of neurological systems. What makes this compound controversial is the economic and political impact it can have among various countries and businesses.
