Abstract An in vitro model utilizing neuroblastoma cell lines was developed for the differentiation of organophosphorus compounds which have the potential for induction of delayed degeneration of peripheral nerves and the spinal cord. IMR-32 neuroblastoma cells, derived from a human tumor, showed specific (3H)-norepinephrine uptake. The greater effect of alkyl over aryl OP compounds suggests a relationship with water solubility, thus equilibrium between adsorption to agar and the surrounding medium or lysosomal contents. The effect of parathion was intermediate, less than that for merphos, DEF and EPN but greater than that for leptophos and TOCP. Electron microscopic observations suggest further studies to define a morphologic lesion peculiar to the clinically delayed neurotoxic OP compounds.
