Posted By Angela Oakey-Jones I'm looking into the levels of contamination of paper money by classified substances (e.g. heroin, amphetamine etc). I am aware that all paper money will show some trace contamination - and that this raises the issue of whether there are acceptable levels of background contamination. I need to know at what level (if one exists) such contamination is considered unacceptable and whether there are any standards against which this can be compared or measured. I have not found anything relating to this in EH40/2002. Whilst I have access to the laboratory testing methodologies for drug contamination, I don't have information specifically relating to money or on simple tests which could be carried out away from a lab setting. I'd be grateful for any information, particularly from members with pharmaceutical or chemical backgrounds. Kind regards Angela Oakey-Jones MIOSH H M Customs & Excise Law Enforcement
