: Ni razpoložljivih informacij.
Nadaljnje informacije
: Posledica zaužitja oktametilciklotetrasiloksana prek
vdihavanja v koncentracijah 500 in 700 ppm je statistično pomembno
zmanjšanje števila rojenih mladičkov in velikosti legla pri prvi in
drugi generaciji podgan. Pri drugi generaciji je pri
izpostavljenosti 700 ppm prišlo do daljšega obdobja gonjenja ter
zmanjšanega parjenja in plodnosti. Povečalo se je tudi število
kotitev, ki so trajale izjemno dolgo časa (distocija). Rezultati
dveletne raziskave o daljši izpostavljenosti vdihavanju hlapov
oktametilciklotetrasiloksana (D4) so pokazali učinke (benignih
žleznih tumorjev maternice) na maternici podganjih samic. Do tega
je prišlo samo pri najvišjem odmerku izpostavljenosti (700 ppm). Do
danes raziskave niso pokazale, da bi do takih učinkov prišlo prek
poti, ki so pomembne za človeka. Na podlagi razpoložljivih
informacij o morebitni škodljivosti človeškemu zdravju so pri
Health Canada, na podlagi presejalnega testa iz leta 2008,
zaključili, da oktametilciklotetrasiloksan ni prisoten v okolju v
količini ali koncentraciji ali pod pogoji, ki predstavljajo ali bi
lahko predstavljali nevarnost življenju ali zdravju Kanadčanov
(http://www.ec.gc.ca/substances/ese/eng/challenge/batch2/batch2_556-67-2.cfm).
Daljša izpostavljenost D4 je po vsej verjetnosti privedla do
kopičenja protoporpirina v jetrih podgan. Brez znanja o določenem
mehanizmu, ki povzroča kopičenje protoporpirina, je pomen tega
odkritja za človeka neznan.

12. EKOLOŠKE INFORMACIJE 12.1 Ekotoksičnost
Lahko povzroči dolgotrajne škodljive učinke na vodno okolje.
Škodljivi vplivi so bili opaženi samo v zaprtih preizkusnih
sistemih.
12.2 Obstojnost in razgradljivost
Hlapni siloksani z nizko molsko maso imajo nizko topnost v vodi
in izhlapevajo. Hlapni siloksani z nizko molsko maso se v zraku
razkrojijo, ko reagirajo s hidroksilnimi radikali, kar je
prevladujoč proces razkroja za večino kemikalij v ozračju. Hlapni
siloksani z nizko molsko maso se iz tal odstranijo z več procesi,
ki sočasno potekajo. Med njimi so izhlapevanje, hidroliza in
razgradnja, katalizirana z glino.
12.3 Bioakumulacija
Hlapni siloksani z nizko molsko maso se biokoncentrirajo v
ribah, ki so izpostavljene nadzorovanim laboratorijskim pogojem, ki
pa ne predstavljajo pogojev v okolju.
12.4 Izpustiti v vode / Mobilnost v tleh
Učinki na naprave za obdelavo odpadne vode:
Ne vpliva škodljivo na bakterije. Siloksani v tem proizvodu ne
povečujejo biološke potrebe po kisiku (BPK). Hlapni siloksani z
nizko molsko maso se učinkovito odstranijo (>90%) med čiščenjem
odpadnih voda, pri tem pa se približno enake količine sprostijo v
ozračje in blato. Hlapni siloksani z nizko molsko maso se v
prečiščenih odpadnih vodah vežejo na trdne delce zaradi zelo nizke
topnosti v vodi.
13. SMERNICE ZA ODSTRANJEVANJE
Odlaganje izdelkov in embalaže
:
Odstranite v skladu z lokalnimi uredbami. V skladu z Evropskim
katalogom odpadkov se kode za odpadke ne ravnajo po proizvodih,
ampak po uporabi. Odpadkom naj bi kode pripisal uporabnik,
prednostno po posvetu z organi, ki so pristojni za odstranjevanje
odpadkov.

This exposure scenario covers production of D4 in the EU. For
the environment, the scenario also covers on-site formulation, and
on-site use as a monomer, chemical intermediate or non-metal
surface treatment agent. In addition, the scenario also covers
formulation and use at sites either importing from non-EU
manufacturers, or purchasing material from EU manufacturers, where
D4 itself is not produced, but other silanes are manufactured.
These additional sites are included because high levels of control
and emission abatement are employed at such locations due to the
highly reactive nature of other materials produced and used
there.

Octamethylcyclotetrasiloxane (D4) (CAS 556-67-2) as a monomer at

It can be seen from the table that the RCR for marine sediment
is nominally above 1 (having applied EUSES default), indicating
that direct discharge of waste water containing D4 from this
exposure scenario is not safe. Treatment of waste water in a waste
water treatment plant before discharge into the marine water is
required to determine safe use. Therefore, downstream users are
required to apply risk management measures of treating waste water
to maintain this use. Applying this risk management measure would
give marine RCR similar to the fresh water value.

4. Guidance to Downstream User to evaluate whether he works
inside the boundaries set by the Exposure Scenario
This exposure scenario covers the use of D4 as a monomer in the
production of siloxane polymers and resins, use as an intermediate
(environment) and use in emulsion polymerisation (environment).
This is in effect use as a monomer. The tonnages described here
cover the amounts of D4 although it will frequently be the case
that higher tonnages of the mixed product (and therefore higher
levels of control) will be in place.

Environment
Given the very small scale use, it is not appropriate to assess
environmental exposure for this scenario. There is no intentional
release of D4 to waste water and any fugitive releases to air will
be of negligible volume. Workers
For industrial spraying (PROC7), inhalation exposure is
quantified using the Stoffenmanager model, with the following input
parameters:
• Products contain 5% D4
• Products are sprayed generating mist or haze
• Use takes places indoors in a location where room volume

3. Exposure estimation and reference to its source
Environment
It can be seen from the table that the RCR for marine sediment
is nominally above 1 (having applied EUSES default), indicating
that direct discharge of waste water containing D4 from this
exposure scenario is not safe. Treatment of waste water in a waste
water treatment plant before discharge into the marine water is
required to determine safe use. Therefore, downstream users are
required to apply risk management measures of treating waste water
to maintain this use. Applying this risk management measure would
give marine RCR similar to the fresh water value.
