This material is a contaminated soil that was obtained from a brickworks site in
Hackney, London.
This material is intended for use as a reference material in the development,
validation or quality control of analytical methods for the determination of extractable
metals and total metals in soils.
The extractable metal content refers to metals soluble in aqua regia using methods
based on ISO11466 (1995).
