Survey of endocrine disruptors in toys and articles for children
Undersøkelse av hormonforstyrrende stoffer i leker og barneprodukter
Summary – sammendrag
58 samples of toys and other articles for children were analysed for phthalates, bisphenols,
alkylphenols and –etoxilates, and/or chlorinated parafins. Some of the substances were detected in
few samples, but in most of the samples analysed, none of the substances were found. The most
noticeable finding was significant amounts of bisphenol A in many of the samples of soft polymer
analysed.
58 prøver av leker og andre barneprodukter ble analysert for ftalater, bisfenoler, alkylfenoler og –
etoksilater, og/eller klorparafiner. Noen an stoffene ble funnet i noen av prøvene, men i en stor del
av de undersøkte prøvene ble ingen av stoffene påvist. Det mest påfallende funnet var betydelige
nivåer av bisfenol A i mange av prøvene av myk plast som ble undersøkt for bisfenoler.

1. Summary and conclusion
A screening survey of selected groups of endocrine disruptors (EDCs) was conducted with 58
samples of toys and other articles for children. The majority of the articles examined were
made from soft polymer (PVC or PU), but some articles made from other materials were also
included in the survey. Samples were analysed for one or several of the following; phthalates,
bisphenols, chlorinated paraffins and alkylphenols/alkylphenol etoxilates. Only some of the
compounds analysed were detected in the samples, but the majority of samples did not
contain any of the substances analysed. Levels varied from traces to relatively high amounts.
The detection of bisphenol A in more than half of the samples where bisphenols were
examined give rice to some concern, especially since some parts of articles that children are
likely to place in their mouths had relatively high levels. However, since migration was not
measured for any of the detected substances, it was not possible to estimate risk of exposure
of any of the substances from the articles in questions.
2. Sammendrag og konklusjon
Utvalgte grupper hormonforstyrrende stoffer ble undersøkt i 58 leker og andre
barneprodukter. De fleste av produktene var laget av myk plast (PVC eller PU), men også
noen produkter av andre materialer ble undersøkt. Prøvene ble undersøkt for en eller flere av
følgende grupper: ftalater, bisfenoler, klorparafiner og alkylfenoler/alkylfenolektoksilater.
Kun noen få av stoffene ble påvist i prøvene, og nivåene varierte fra spormengder til relativt
høye konsentrasjoner. De fleste produktene inneholdt ingen av de undersøkte stoffene.
Bisfenol A ble funnet i over halvparten av prøvene som ble analysert for bisfenoler, i noen
tilfeller i relativt høye konsentrasjoner i deler av produktene som det er sannsynlig at barn vil
putte i munnen. Dette gir grunn til bekymring. Imidlertid ble det ikke utført
utlekkingsanalyser for noen av de stoffene som ble påvist, så det er ikke mulig å estimere
eksponeringsrisiko for noen av stoffene fra de produktene det er snakk om.
3. Background and aim of the project
Chemicals are an essential component of our daily lives, and are important for function and
properties of the articles we use and need every day. Some chemicals, however, can be
harmful for humans and/or for the environment. Some chemicals can interfere with the
endocrine (hormone) systems of humans and wildlife, with potentially adverse effects. These
chemicals are referred to as endocrine disrupters (ECDs).
Endocrine disrupters interfere with natural hormone systems, and health effects can appear
long after the exposure has stopped. Exposure to ECDs in critical developmental stages can
interfere with sexual development in both humans and animals. Exposure to endocrine
disrupters in the womb can have life-long effects and can even have consequences for the
next generation. Babies and young children are also especially vulnerable to exposure from
ECDs, both because their bodies and organs are not fully developed and are changing rapidly,

and because their intake of substances relative to their body weight is high compared to
adults.
Children spend a lot of time interacting with their toys, and toys are subject to close body
contact as well as being sucked on, bitten into and licked. There is a huge potential for
exposure of harmful substances to children from toys through the skin or via oral intake. It is
important to minimize children’s risk of exposure to harmful chemicals via their toys, and
toys in Europe are strictly regulated with respect to harmful chemicals. There is, however, a
lack of specific regulations concerning ECDs in toys, and to how to handle substances with
known or suspected endocrine disrupting properties at low concentration. There is also a lack
of knowledge regarding the potential for occurrence of ECDs in toys. The present survey was
conducted as a screening of the presence of selected ECDs in toys and other children’s
articles on the Norwegian market.
The chemicals measured was selected by cross-referencing the EU list of ECDs or suspected
ECDs with substances categorised as ECDs on the SIN-list* and the Norwegian list of priority
substances. From the resulting list of substances, a further selection was made from those
considered likely to be present in the type of materials often used in toys. This lead to the
following list of chemicals to be measured in selected types of toys or other children's articles
made from selected materials:
Phthalates
Nonyl- and octylphenol and their etoxilates
Short- and medium chained chlorinated paraffins
Bisphenols
4. Materials and methods
Children are particularly vulnerable to endocrine disrupters. Hence, the current project is
focused on articles for children, and more specifically the parts of the articles that can (and
are likely to) be put in the mouth by a child. The type of articles were not limited to articles
for very young children, who are generally more inclined to mouthing of toys and other items,
but were selected from items that also older children may be likely to suck, chew or lick on.
In addition to oral exposure, the potential for dermal exposure or leaking of chemicals into
children’s indoor environment was considered when selecting articles.
A total of 58 toys and other articles for children were purchased for the project. The articles
were predominantly made from hard and soft plastics/polymers and rubber/silicone. In
addition, a number of outdoor clothing items made from water and/or wind repellant
material, and some appendages and accessories to the clothes, were obtained. Articles were
purchased in toy stores, bookstores and sports shops in the period April – June 2014. Not all
samples were analyzed for all chemicals. Details of samples and analysis are given in
appendix 1.
The samples were analyzed by ALS Laboratory Group Norway AS or their sub-contractors, in
the period September – November 2014.

Phthalates were extracted with an organic solvent in an ultrasound bath, and determined by
GC-MS according to DIN-19742:2012-04, with a limit of quantification (LOQ) at 0.05 % (w/w).
Details of which substances were determined in the analysis are given in table 1.
Short- and medium-chained chlorinated paraffins were determined by GC-NCI/MS according to
ISO 12010, with an LOQ at 0.10 mg/kg. Short-chained chlorinated paraffins (SCCP) have 10-13
carbon chain lengths, while medium-chained chlorinated paraffins (MCCP) have 14-17 carbon
chain lengths. Individual compounds in each group were not quantified. Results were given as
sum SCCP or sum MCCP.
Nonylphenol (NP), octylphenol (OP), and their etoxilates (NPe and OPe, respectively), were
determined using GC-MS according to EN ISO 18857-2. Individual substances were not
quantified. Results are given as sum NP, sum OP, sum NPe and sum OPe.
Bishpenol A was extracted with an organic solvent in an ultrasound bath, and determined by
GC-MS according to EN ISO 22032:2009-07, while other bisphenols were determined by GC-MS
according to ASTM D7574:2009. LOQ for all bisphenols were 1 mg/kg. Details of which
substances were determined are listed in table 1.
In the methods for phthalates and bisphenols, the following substances were determined:

5. Results and discussion
In total, 58 samples of toys or other articles for children were analysed for one or more of the
groups of substances described above. Of these, 28 samples were made from “soft polymer”,
several of which were most likely PVC. Ten samples were wet weather clothes made from
polyurethane. The rest of the samples were made of rubber/latex/elastan, textiles/synthetic
fibres or other polymers (hard polymers), and there were a few samples of modelling clay and
slime.
Details of samples, analysis and results are presented in appendix 2.
Phthalates were only detected in six of the 50 samples where this was examined. In three of
the samples only trace amounts were found, 0.11 % DIBP, 0.17 % DEP and 0.29 % DEHP,
respectively. In the remaining three samples, DEHP was found in concentrations of 3.5 %, 15 %
and 19 %. All of the phthalates were found in samples of “soft polymer”, most likely PVC. All
articles where phthalates were detected fall outside the scope of the restriction of phthalates
in toys and childcare articles (REACH annex XVII, entries 51 and 52). However, some of the
articles (pendants and fabric of outdoor clothing), are articles that children can put in their
mouth and chew or suck on for longer periods. The risk of exposure from these articles have,
however, not been estimated.
Short-chained chlorinated paraffins (SCCPs) were detected in three of 41 analysed samples. A
pencil case was found to contain 1600 mg/kg (0.16 %), the fabric of a rain jacket contained
5100 mg/kg (0.51 %) and 66 000 mg/kg (6.6 %) was found in the zipper pendant of another
rain jacket. In the first two samples, medium-chained chlorinated paraffins (MCCPs) were also
measured, at levels of 3400 mg/kg and 7600 mg/kg, respectively. SCCPs are prohibited in
articles through the POPs regulation (regulation (EC) no 850/2004). Accordingly, the two rain
jackets were non-compliant articles, and was withdrawn from the market. The 0.16 % SCCPs
found in the pencil case, was considered an unintentional trace contaminant, hence the
pencil case was not considered a non-compliant article. The content of 66 000 mg/kg (6.6 %
by weight) in the zipper pendant of one of the rain jackets, is of particular concern, as this is
a part of the jacket that children may put in their mouth, increasing the risk of oral exposure
to SCCPs from this article.
In addition to the above-described findings of chlorinated paraffins, trace amounts of MCCPs
were detected in zipper pendant from a third rain jacket. The same zipper pendant also
contained trace amounts (0.29 %) of DEHP.
Nonylphenols (NFs) were found in three of 16 samples analysed, in concentrations from
23 mg/kg to 670 mg/kg. All samples were soft polymer (possibly PVC). In a fourth sample of a
soft polymer, 12 mg/kg nonylphenol etoxilates (NPEs) were detected. At the time of testing,
there were no restrictions for these compounds in the samples were they were detected.
A surprisingly high number of the samples that were analysed for bisphenols came out positive
for bisphenol A (BPA). Bisphenols were only measured in 16 samples, and BPA was found in
nine of them. Of these, eight of the samples were made from soft polymer, most likely PVC.
In the PVC samples, trace amounts (2.6 mg/kg) was detected in one item, in the remaining

seven articles, levels of BPA was between 16 mg/kg and 160 mg/kg. In one sample made from
hard polymer, 1.1 mg/kg BPA was measured. This level was just above the detection limit of
1 mg/kg. No other bisphenols were found in any of the samples analysed.
At the time of purchase of the samples, BPA was restricted in toys if the under the general
ban on CMR-substances in toys. However, the ban in not applicable if the content of the
substance is below the classification limit for substances, in this case the limit for
classification at the time was 5 %. The detected levels were well below this limit. Hence, the
articles in question were compliant with relevant legislation.
Some of the samples where the highest levels of BPA were detected were pendants or
appendages of such size and shape that children can, and most likely will, put them in the
mouth. If BPA were to migrate from these articles, there is a risk of oral exposure of BPA
from these articles. However, as migration analysis were not conducted as part of this
project, the risk of BPA exposure, cannot be estimated.
6. Concluding remarks
Of the 58 samples analysed in this survey, only a few of the selected EDCs were found in
significant levels in relatively few of the samples. Two articles were withdrawn from the
market due to content of SCCPs. In the remaining cases where substances were detected,
either the articles were outside the scope of a regulation, or levels detected were below
regulatory limits. Still, some findings give rise to concern. In particular, the detection of BPA
in more than half of the samples analysed may initiate further investigations of the presence
of BPA/other bisphenols in articles for children.
