Paul Whitehead is chairman of the RSC Environment, Health and Safety Committee.

Decline in levels of scientific literacy in recent years has contributed to irrational fears about the hazards and risks associated with the use of some chemicals. This is often compounded by some campaigning organisations providing simplistic and emotional arguments based on dubious science in support of political objectives.

The media, too, are quick to exploit fashionable ideas, which are not backed by objective scientific analysis. In this environment it is often difficult to make rational decisions in our daily lives about the real risks and benefits posed by exposure to some chemicals.

In order to address some of the misconceptions, the Environment, Health and Safety Committee (EHSC) of the RSC has initiated a series of accessible themed Message Notes (entitled: Why do we worry about..?). These present balanced scientific information on the uses and risks of different chemicals.

These notes are designed for decision makers and the public who may not have an in-depth knowledge of chemistry. They are produced by experts drawn from industry, academia and government, committed to ensuring that policies to regulate the safe use of chemicals are based on scientific knowledge, and are proportionate to the risks. Introductory notes explain basic concepts such as risk and hazard: terms often applied incorrectly. The series also covers chemicals of public concern, such as perfumes, and more Message Notes will follow shortly.

We urge you read these notes and pass them on to those who may be interested.
