Public perception of the value of chemicals in daily life depends on a
n often irrational set of conclusions reached on partial or defective
information often derived from single issue pressure groups. Benefits
are consistently undervalued, clean water and uncontaminated food are
taken for granted and changes in the pattern of disease are assumed to
have occurred as a result of other kinds of intervention. If we are t
o ensure a proper evaluation of the place of chemicals in our lives th
en we will have to persuade opinion formers of the need for rational d
ebate, inform the scientifically literate part of the population about
hazard, risk? the difficult concept of safety and the dangers of mist
aking association for causation. Changes in science in the field of to
xicology give us a more reasonable ground for this debate than has exi
sted in the past and the way in Which these can be exploited will be d
iscussed.
