UK panel revealed consumer understanding of nanotechnology |
(Nanowerk News) In November 2007, Which?, the UK consumer advocat group, commissioned a short survey among the
general public which highlighted low levels of awareness for
nanotechnologies and how they are being used (2091 adults were interviewed):
|
Six in ten adults had not heard of the term ‘nanotechnology’ (61%).
Among those aware of the term, around two thirds (64%) believed
nanotechnologies were already being used to develop consumer products
of some kind; just under one in twenty did not think they were being used
to develop any (4%), but a third simply did not know (33%).
|
Following on from this, Which? undertook an additional research project
with consumers - the Citizens’ Panel on Nanotechnologies.
|
OBJECTIVES & RESEARCH METHOD
|
The primary objectives of the Citizens’ Panel were to explore consumer perceptions
and understanding of nanotechnologies and to investigate the implications of
nanotechnologies for all consumers - from the consumers’ point of view. The panel
focused in particular on the areas of food, cosmetics, medicines/health and
consumer products.
|
Over three days, the panellists learnt about nanotechnologies and their applications
from a number of expert witnesses. Throughout the process, panellists were able to
ask questions of the witnesses and were given issues to discuss and debate with
each other. They were asked to come up with both ‘shared solutions’ and to give
their individual responses.

KEY INSIGHTS
|
Initial Reactions
|
Initially there was very little awareness of nanotechnologies among the panellists,
but by the third day they were comfortable discussing the topic and their possible
applications and risks.
|
Panellists were generally excited about the potential that nanotechnologies offer
and were keen to move ahead with developing them. However, they also recognised
the need to balance this with the potential risks.
|
Panellists identified many opportunities for nanotechnologies. They appreciated the
range of possible applications and certain specific applications, particularly for health and medicine. The potential to increase
consumer choice and to help the environment were
also highlighted, along with the opportunity to ‘start
again’ by designing new materials with more useful
properties. Other opportunities they highlighted
were potential economic developments for the UK
(and the jobs this might create) and the potential to
help developing countries (with food or cheaper
energy).

Key issues
|
During the three days of discussion and debate
various issues arose:
|
Safety - potential safety issues were a key concern
(e.g. the toxicity of nanoparticles). Of particular
concern was the fact that there are already
products on the market where scientists are
uncertain of the safety of the nanomaterials
involved, specifically if these involve ‘free’
nanoparticles.
Lack of regulation - panellists were concerned that
industry is able to make positive marketing claims
with regards to the new properties of
nanomaterials, while denying that they may have
any undesirable new properties. There was
consensus that industry should not be allowed to
self-regulate, and concern that no regulations
specifically to deal with issues raised by
nanotechnologies appear to exist currently. It was
also agreed that any regulations need to be
applied internationally.
Information - there were concerns that there are
currently no requirements to inform consumers
about products using nanotechnologies - but
panellists also acknowledged that this information
would not be useful unless the public were given
broader information on the subject at the same
time. Panellists were also more concerned for the
need for information about ‘free’ nanoparticles
than fixed (e.g. food and cosmetics rather than
phones and cameras).
Accessibility - questions were raised over whether
nanotechnologies would be accessible to all, or just
to the rich or richer countries.
Environment - the possible environmental impacts
were raised - would nanoparticles enter the
environment and, if so, would they persist longer?
|
Action points
|
From a consumer perspective, panellists believed the
following areas should be tackled:
|
Public safety: the panellists saw the potential for
nanotechnologies and while they did not want to
call for a halt to their development they were keen
that they be developed with the highest regard for
public safety.
Regulation: safety standards and regulations
applicable to nanotechnologies should be
addressed urgently. Panellists suggested greater
Government involvement in their control as well as
an independent body or bodies - either to regulate
generally or in specific areas. They also stressed
the need for independent safety assessments, and
called for regulations to be applied internationally
to protect consumers in a globalised market.
Public information: consumers should be informed
about nanotechnologies - both in terms of
whether they have been used in product
development and more widely about the issues
concerning nanotechnologies - to help them
decode any information they may be given on
product labels. Once again, panellists were
particularly concerned that consumers be
informed about ‘free’ nanoparticles.
