Fig. 4.
Concentration–response curves of AChE activity following exposure to the five inhibiting compounds for all (20) donors: chlorpyrifos-oxon (CPO; a), phosmet-oxon (PMO; b), diazinon-oxon (DZO; c), pirimicarb (PI; d), rivastigmine (RI; e). Each symbol-colour combination represents one donor. Data are presented for each donor as the percentage of vehicle control AChE activity for that donor (mean ± SD of three technical replicates)
