Our work
The use of toxicity data on a structurally-similar compound to evaluate a substance that has been inadequately tested – the so-called “read-across” approach – is a crucial part of the toxicologist’s skill set. Exploiting read-across can minimise the number of new tests conducted on vertebrate animals, while still ensuring that chemicals are safe for workers and the general population. We have been routinely using read-across in our hazard and risk assessments for many years, and have often incorporated it into the REACH regulatory submissions we have prepared.
