| Short description: |
The results and conclusions of an inter-Laboratory Comparison of in vitro Bioaccessibility Measurements for Arsenic, Lead and Nickel in Soil
|
| Long description: |
This study forms part of the Environment Agency's wider work programme on in vitro bioaccessibility testing in England and Wales. Our aim was to gain knowledge on the type of bioaccessibility tests currently offered by laboratories in England and Wales for land contamination assessments. We also wanted to understand how the laboratories report these results and how the different results compare. We distributed three soil samples with varying levels of arsenic, lead and nickel to 11 laboratories (nine laboratories operated within the UK and two laboratories were located overseas). The US Environmental Protection Agency donated a soil sample previously tested on people (in vivo) which we also distributed to selected UK laboratories. Although conducting an inter-laboratory exercise was not the primary aim of this study, we did carry out an inter-laboratory trial. Procedures adopted by the CONTEST soil proficiency-testing scheme were followed, in order to ensure that all laboratories received exactly the same sample. We requested that the laboratories report analytical results for total metal concentrations and in vitro bioaccessibility estimates using their normal procedures and reporting formats.
The data from the inter-laboratory exercise support a number of conclusions regarding the use of these tests in England and Wales
