Fire fighting foams: Estimated to be 570 kg PFOS-acid/year ,
(In 2005, the accident in Buncefield (UK), might have lead to a
much higher release.)
Photographic industry: Estimated to be about 6.75 kg PFOS-
related substance /year from film development, and 1.02 kg
PFOS-acid/year into waste water and 0.051 kg PFOS-acid/yaer
into the air from manufacturing of films. Semiconductor
industry: If complete elimination of the use in developers is
assumed (as indicated by industry), about 43 kg PFOS-related
substances /yaer are estimated to be released to the
environment.
Aviation industry: Releases into water were estimated to be
3.94 kg PFOS-acid/year, and to soil 9.2 kg PFOS-acid/year.

Explanatory note:
2. This information was requested for preparation of the risk profile in accordance with Annex E
of the Convention. The POPRC would like to collect more information on these items. If you
have additional or updated information, kindly provide it.
A. Efficacy and efficiency of possible control measures in meeting risk reduction goals
(provide summary information and relevant references):
The total production of PFOS has been significantly reduced
from 2000 to 2005 due to a phase out by the main producer in
the US (see also “uses”). However, by our current knowledge
the Italian company Miteni does still produce PFOS. For most
uses, more environmental friendly alternatives are available.
For some purposes, however, still a phase out is needed and
needs to be controlled, e.g. a programme need to be etablished
for the destruction of the existing stocks of fire fighting foams
containing PFOS. For other uses, e.g. in semi-conductor
(i) Describe possible industry, no alternatives are yet known/explored. here, the
control measures scientific research on alternatives need to proceed and the
current use (estimated 470 kg/year in the EU) needs to be
controlled. The SIA (Semiconductor Industry Association) is
cooperating and provided information on the situation and on
possible controll measures at the TF-meeting under the POPs-
Protocol of LRTAP in 2006 (see Document attached).

meeting in 2006).
Office location: International Environment House, 11-13 chemin des Anémones, Châtelaine, 1219, Geneva, Switzerland

fire fighting foams: Alternatives need to be further
investigated; destruction of currents stocks under discussion
(RPA & BRE report, 2004). (A lot of the UK stocks have
possibly been used after the Buncefield accident in 2005.)
- no substitutes known yet for uses in semiconductor
industry, photography and avaitaion industry; control
in semiconductor industry seems possible: see “SIA-
(ii) Technical SEMI U.S. PFAS Mass Balance”, presentation given
feasibility by SIA at the POPs-Protocol TF in 2006 (document

environmental and POPs, Bo Walström, and presented to the POPs-Protocol TF
health costs at it´s last meeting in 2006.
Explanatory notes:
3. If relevant, provide information on uses for which there may be no suitable alternative or for
which the analysis of socio-economic factors justify the inclusion of an exemption when
considering listing decisions under the Convention. Detail the negative impacts on society that
could result if no exemption were permitted.
4. “Risk reduction goals” could refer to targets or goals to reduce or eliminate releases from
intentional production and use, unintentional production, stockpiles, wastes, and to reduce or
avoid risks associated with long-range environment transport.
5. Provide the costs and benefits of implementing the control measure, including environmental
and health costs and benefits.

Explanatory notes:
7. Provide a brief description of the alternative product or process and, if appropriate, the
sector(s), use(s) or user(s) for which it would be relevant.
8. If several alternatives could be envisaged for the chemical under consideration, including
non-chemical alternatives, provide information under this section for each alternative.
9. Specify for each proposed alternative whether it has actually been implemented (and give
details), whether it has only reached the trial stage (again, with details) or whether it is just a
proposal.
10. The evaluation of the efficacy should include any information on the performance, benefits,
costs, and limitations of potential alternatives.
11. Specify if the information provided is connected to the specific needs and circumstances of
developing countries.
12. The evaluation of the risk of the alternative should include any information on whether the
proposed alternative has been thoroughly tested or evaluated in order to avoid inadvertently
increasing risks to human health and the environment. The evaluation should include any
information on potential risks associated with untested alternatives and any increased risk
over the life-cycle of the alternative, including manufacture, distribution, use, maintenance
and disposal.
13. If the alternative has not been tried or tested, information on projected impacts may also be
useful.

also be useful.
C. Positive and/or negative impacts on society of implementing possible control
measures (provide summary information and relevant references):
A positive impact on human health and on the environment
(i) Health, including can be expected from a ban of PFOS on a global scale. The
public, environmental stablishment of further controll measures for those uses of
and occupational PFOS, where no substitution is yet possible, will presumedly
health contribute positively to human health and the environment,
especially concerning reprotoxicity and blood values.
A positive impact on human health and on the environment
(ii) Agriculture, can be expected from a ban of PFOS on a global scale. The
including aquaculture stablishment of further controll measures for those uses of
and forestry PFOS, where no substitution is yet possible, will presumedly
contribute positively to nature.

(iii) Biota As the persistent, bioaccumulative and toxic properties of
(biodiversity) PFOS were shown under the POPs-Protocol and under the
Office location: International Environment House, 11-13 chemin des Anémones, Châtelaine, 1219, Geneva, Switzerland
Secretariat of the Stockholm Convention page 6
Stockholm Convention, a positive impact on biota from a
ban/restriction of the substance can be expected.
An evaluation of costs arising when replacing PFOS in
different uses has been elaborated by the Swedish expert on
(iv) Economic aspects POPs, Bo Walström, and presented to the POPs-Protocol TF
at it´s last meeting in 2006.
As the persistent, bioaccumulative and toxic properties of
PFOS as well as it´s potential for a long-range transboundary
(v) Movement transport were shown under the POPs-Protocol and under
towards sustainable the Stockholm Convention, a positive impact on a globally
development sustainable development from a ban/restriction of the
substance is be expected.
(vi) Social costs -
Explanatory notes:
15. Socio-economic considerations could include:
Any information on the impact (if any), costs and benefits to the local, national and regional
economy, including the manufacturing sector and industrial and other users (e.g., capital costs
and benefits associated with the transition to the alternatives); and impacts on agriculture and
forestry;
Any information on the impact (if any) on the wider society, associated with the transition to
alternatives, including the negative and positive impacts on public, environmental, and
occupational health. Consideration should also be given to the positive and negative impacts on
the natural environment and biodiversity.
Information should be provided on how control measures fit within national sustainable
development strategies and plans.
D. Waste and disposal implications (in particular, obsolete stocks of pesticides and
clean-up of contaminated sites) (provide summary information and relevant
references):
Although PFOS is not used for the manufacturing of fire
(i) Technical fighting foams anymore, there are still stocks of ca. 122 tonnes
feasibility in the EU (estimated in 2004). (Source: Working Document of
the POPS-Protocol TF-mmeting in June 2006)
According to the Swedish expert on POPs, the low cost of
destruction of fire fighting foam (1,000 EUR per ton) and the
replacement costs of new foam (5,000 EUR per ton) makes it
(ii) Costs rational to destroy all fire fighting foams. It is cost-effective to
destroy tzhe stock when comparing with emission reduction
options from other uses. (Source: Working Document of the
POPS-Protocol TF-mmeting in June 2006)
