Table 2

Margin of Exposure (MOE) of organophosphate pesticide residues for vegetable growers.

Pesticide	Frequency Below EPA MOE approach	Margin of exposure (MOE)
		GEM*	25%	50%	75%	90%
Chlopyrifos	39%	167	333	143	67	33
Dicrotophos	87%	385	1000	312	208	89
Profenofos	0%	13857	32333	16167	3129	1077

US EPA MOE Chlorpyrifos =100, dicrotophos =1000, profenofos =300
MOE < US EPA MOE approach mean risk concern.
