PON1 status does not influence cholinesterase activity in Egyptian agricultural workers exposed to chlorpyrifos. [PDF]

open access: yes, 2012
Animal studies have shown that paraoxonase 1 (PON1) genotype can influence susceptibility to the organophosphorus pesticide chlorpyrifos (CPF). However, Monte Carlo analysis suggests that PON1 genotype may not affect CPF-related toxicity at low exposure ...
