The Countess of Mar

asked Her Majesty's Government:

What is the long-term effect of low level exposure to organophosphates upon the ability of humans and animals to synthesise PsChE.

Baroness Cumberlege:

There is some evidence for effects of anticholinesterases, including organophosphates on the rates of synthesis of cholinesterase enzymes, generally at doses that produce evidence of depression of cholinesterase activity.
