Hola Mario!

?Existe algun mecanismo propuesto por UNEP, los expertos y/o los pa?ses para agilizar el procedimiento de postulaci?n, revision y adici?n de COP al convenio? ?Y para promover activamente que los pa?ses actualicen sus PNI en consecuencia?

Leonor Cedillo (from Mexico)
Hola Leonor,

Cualquier Parte del Convenio puede proponer una sustancia para ser incluida en alguno de los listados del mismo. En base al artculo 8 del Convenio, la Parte interesada poder ser apoyada por otra Parte y/o por la Secretara en la elaboracin de la propuesta. Una vez presentada la propuesta, la revisin de la sustancia se debe llevar a cabo bajo el procedimiento que sigue el Comit de Revisin de POPs.

En cuanto a la actualizacin de los PNI, la Secretara cuenta con programas de asistencia tcnica para capacitar y apoyar los pases a llevar a cabo el trabajo de actualizacin. Se cuenta adems con guas especficas para orientar a las Partes en esta actividad. Como referencia, puedes consultar el siguiente sitio:

Gracias por tu consulta

Hello Mario,

I have a few questions about the effect of a chemical being listed under the Stockholm convention.
As there are probably many potential hazardous chemicals to be listed, how are these prioritized by the committee?
Once a chemical is listed as a POP under the convention,do governments who have signed the convention have to agree to publicize the agreement and inform industry? Also is there a procedure and recommendations made that goes into act to support countries looking for alternative solutions?
philip Hamilton (from France)
Hello Philip,

The mandate of the Committee is to review the proposals for listing new chemicals based on the information specified first on Annex D (screening phase) and then on information contained in Annexes E and F. Based on the outcomes of the review process, the Committee then makes a recommendation to the Conference of the Parties.

Under Article 10, on public information, awareness and education, each Party shall, within its capabilities, promote and facilitate provision of all available information on POPs and encourage industry and professional users to promote and facilitate the provision of the information.

Finally, several projects are under implementation to identify and assess alternatives to some of the chemicals listed under the Convention. The outcomes of this work have been useful in supporting countries by making available information on alternatives.

God morning,

I'd like to know if any country part of these conventions can submit a proposal for a new substance to be included in the list?
Ram?n Herrero Crespo (from Spain)
Good morning Ramn,

Yes, Parties to the Conventions can submit proposals for listing chemicals.

According to Article 8 of the Stockholm Convention any Party may submit a proposal to the Secretariat for listing a chemical in Annexes A, B and/or C. In this case, the proposal shall contain the information specified in Annex D of the Convention and if the criteria is met, the proposal is forwarded to the POPs Review Committee .

For the Rotterdam Convention, at least one notification from each of two Prior Informed Consent regions regarding a particular chemical that the Secretariat has verified meet the requirements of Annex I to the Convention, shall be then forwarded to the Chemical Review Committee.

Are there parties of the Stockholm Convention that have asked for Lindane exemptions? If so, what parties and for what uses? Is UNEP developing activities to identify alternatives to Lindane to help those countries in successfully phasing out all Lindane uses?
Irina Ize (from Mexico)
Hello Irina and thank you for your questions.

There are currently three Parties on the Register of specific exemptions for Lindane. These are Canada, China and Sri Lanka. You can find out more information on the purpose of use and reasons for exemption on the following link:

On your questions related to alternatives to Lindane, recent work has been carried out by UNEP to assess the availability of alternatives and the continued need for the use of lindane for the treatment of head lice. A report of this work will be presented at the seventh meeting of the Conference of the Parties to the Stockholm Convention.

Gracias y saludos

Who does the assessment of the scientific information before Chemicals are listed under the conventions ?
David Decharte (from France)
Hello David,

The information is reviewed by experts of the subsidiary bodies to the Conventions.

For the chemicals under the Stockholm Convention, the work is undertaken by the Persistent Organic Pollutants Review Committee (see )

In the case of the Rotterdam Convention, the work is carried out by the Chemicals Review Committee (see .)

In both cases, experts are designated by governments which are Parties to the Conventions.

Thanks for your question

Dear Mario,
I have a question concerning the Stockholm convention, what kind of information is required to assess chemicals under the above mentioned convention?
Thanks for your time,
Juan Garc?a-Ar?ez (from Switzerland)
Dear Juan, thanks very much for your question.

The assessment of a chemical under the Stockholm Convention is based on information such as: the sources (use, production, releases), persistence, environmental fate, bioaccumulation, exposure, monitoring data, long-range transport potential of the chemical and its adverse human health and /or environmental effects (See Annex E of the Convention).

In addition, the evaluation of information on possible control measures for the chemical is also an important step of the assessment (See Annex F of the Convention).
