The following resources, many of which are referenced on this page, provide more information on POPs, the Stockholm Convention and the U.S. role in reducing and eliminating POP files. PCP can be found in two forms: PCP itself or in the form of PCP sodium salt that dissolves easily in water. The Stockholm Convention was adopted by Regulation 850/2004 on EU legislation.  In 2019, this regulation was replaced by the Regulation (EU) 2019/1021.  POPRC-9 proposed napthalins and hexachlorobutadiens for inclusion in Appendixes A and C, sorting, grouse, penta, hexata, hepta and octa. She has set up other work on pentachlorophenol, its salts and esters, as well as decapromphemene ether, perfluorooctanesulfonic acid, its salts and perfluorooctane chloride.  Contracting parties must take steps to refrain from producing and using the chemicals listed in Schedule A. Specific exceptions are provided for in Schedule A and apply only to contracting parties who have registered on their account.
The United States has taken strong national steps to reduce POP emissions. For example, none of the original POP pesticides in the Stockholm Convention are now reported for sale and distribution in the United States, and in 1978, Congress banned pcB production and severely restricted the use of remaining PCB stocks. In addition, since 1987, the EPA and the states have effectively reduced the release of dioxins and furans on land, air and water from U.S. sources. These regulatory measures, as well as the voluntary efforts of the U.S. industry, resulted in a more than 85% decrease in total dioxin and furane emissions after 1987 from well-known industrial sources. To better understand the risks associated with dioxin releases, the EPA has conducted a comprehensive reassessment of dioxin science and will evaluate additional measures that could further protect human health and the environment. In 1972, the United States and Canada signed the first Great Lakes Water Quality Agreement, which called on both countries to eliminate and control pollution of these waters. In 1978, they signed a new agreement that added a commitment to cooperate in the elimination of persistent toxic toxic chemicals from the Great Lakes, some of which are POPs. As part of this agreement, the two countries have been monitoring atmospheric exposure of these chemicals in the Great Lakes since 1990. In the EEC-UN region, information on substitutions and alternatives is extremely limited, as NCPs are no longer used.
The only information available is that the NCP has been replaced by other chemicals since the shutdown of NCP production in the 1970s and 1980s. These chemicals have not been identified and described (EEC-UN 2007). In Appendix A, with a special exemption for the use of these chemicals as a product for recycling under Schedule A, Part IV (SC-4/14 decision), the EPA continued regulatory control and management of dioxins and furans released into the air, water and soil. The Clean Air Act provides for the application of maximum control technology for hazardous air pollutants, including dioxins and furans. Among the main sources regulated by this authority are the incineration of municipal, medical and hazardous waste; pulp and paper manufacturing; and some metal production and refining processes. Dioxin emissions in water are managed by a combination of risk-based tools and technology developed under the Clean Water Act. Cleaning up areas contaminated with dioxin is an important part of the EPA Superfund and Resource Conservation and Recovery Act corrective action program.
