What long-term health monitoring is being undertaken on the people who took part in the pesticide testing carried out on behalf of Bayer.

I understand that this question relates to a study carried out by a contract research organisation in Scotland in which eight healthy adult volunteers were exposed to the organophosphate pesticide azinphos methyl. The study was based on an "ascending-dose protocol" wherein the dose to volunteers was increased from very low levels to those at which the first signs of changes in acetylcholinesterase were observable. It was overseen by an independent ethics committee.
