Scientists working under contract for Dow Chemical, which manufactured chlorpyrifos, published a complex model in 2014 to estimate how much of the pesticide a person would have to consume or inhale to trigger acetylcholinesterase inhibition. But some of their equations were based on data from as few as six healthy adults who had swallowed capsules of chlorpyrifos during experiments in the 1970s and early 1980s – a research method that now would be considered unethical.
That's quite a background history for evaluation of safety.
