This is the unofficial website for work at Lancaster University, investigating how systematic review methods can help scientists and policy-makers make best use of the best evidence in assessing and managing health risks posed by chemicals.

The site is maintained by Paul Whaley, a research consultant, Associate Editor for Systematic Reviews at Environment International, and part-time PhD student at Lancaster Environment Centre who may one day finish his studies.
