§ 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.
