HAND BLENDERS USED FOR COOKING CAN EMIT PERSISTENT CHEMICALS
Eight out of twelve
tested models of hand blenders are leaking chlorinated paraffins when used
according to the suppliers' instructions. This is revealed in a report from
Stockholm University where researchers analyzed a selection of hand blenders
which are available on the Swedish market. Chlorinated paraffins are included
in the subject group of persistent organic pollutants which humans and animals
should be protected from.
The tested hand
blenders were bought in stores in Sweden and analyzed in order to determine if
they leak chlorinated paraffins to food under normal use.
"The results
showed that eight of the twelve tested hand blenders emit chlorinated paraffins
during normal household use. In five of them, the levels are high in our
opinion," says Åke Bergman, Professor at the Department of Materials and
Environment Chemistry, Stockholm University, and Head of Swetox. We have
reported the discovery to the Swedish Chemicals Agency and the Swedish National
Food Administration and informed the suppliers of the tested hand blenders.
Chlorinated paraffins
with short carbon chains (C8-C12) are highly toxic to aquatic organisms and may
cause long-term adverse effects in the aquatic environment because they are
stable, recalcitrant compounds that are stored in the environment. Short-chain
chlorinated paraffins affect the liver, kidneys and thyroid and are possibly
carcinogen. Leaks that were detected in the study include chlorinated paraffins
with both short and medium-long carbon chains.
"This means that
the use of two-thirds of the tested hand blenders will lead to human exposure
to materials stored in the body in the same way as, for example PCBs. A
substance that is prohibited to use in products for more than 40 years,"
says Åke Bergman.
Chlorinated paraffins
are used in cutting fluids in the metal industry and as plasticizers and / or
fire retardants in plastics.
"Chlorinated
paraffins appear to be in the hood just above the rotating blade in the hand
blender. However, there are many questions to ask regarding how and why
chlorinated paraffins are used in hand blenders," says Åke Bergman.
It was when the
researchers analyzed cat food in a project on organic pollutants that they
found clear traces of chlorinated paraffins in the tested cat food. Repeated
analyzes showed that the cat food had been contaminated by a newly purchased
hand blender used to homogenize the cat food. The researchers went further and
tested another twelve hand blenders of different brands and models.
"The study needs to
be followed up by more work for a comprehensive picture, but the result is
unambiguous. People can be exposed to substances harmful by ingestion of food
that has been mixed which is serious, especially if it affects small
children," says Åke Bergman. "This discovery also shows once again
that it is impossible with current Swedish law to keep track of what substances
are used when it comes to chemicals."
