Survey published on the use of bioaccessibility
testing in contaminated land risk assessment in
England and Wales
The results of a questionnaire- and interview-based study involving 151 Local Authority Contaminated Land Officers from England and Wales indicate that 
bioaccessibility is perceived as a useful tool that facilitates contaminated land management (70% of survey participants either ‘strongly agreed’ or ‘agreed’
with the statement). The study was conducted by the University of East Anglia in collaboration with the Chartered Institute for Environmental Health and Newcastle
City Council. It was also apparent from the research that information on polycyclic aromatic hydrocarbons, with a particular interest in benzo[a]pyrene
is needed (indicated by 65% of survey participants) to aid decision-making on sites contaminated with these compounds. The Officers indicated lack of guidance
(78%) and uncertainties associated with bioaccessibility (71%) as main constraints upon or barriers to the use of bioaccessibility. This research also determined
models used by Local Authorities to evaluate land contaminated with polycyclic aromatic hydrocarbons and the frequency of bioremediation of PAH-contaminated
land. The report and a further manuscript based on the study also contain a discussion on bioavailability and bioaccessibility terminology and social and institutional
factors hampering the adoption of bioaccessibility within contaminated land decision-making. Survey on bioaccessibility implementation: ... For more information:,
