Toxicity endpoints, uncertainty and FQPA safety factors for calculation of aggregate and route-specific risk from chlorpyrifos and diazinon exposure.

Pesticide		Dermal	Inhalation	Ingestion
chlorpyrifos a	NOAEL (mg/kg/day)	0.03; 3% absorption	0.03	0.03
	uncertainty factor	100	100	100
	FQPA safety factor	10	10	10
diazinon b	NOAEL (mg/kg/day)	1	0.026 c	0.02
	uncertainty factor	300	300	100
	FQPA safety factor	1	1	1

^a [47]; ^b [48]; ^c Based on lowest-observable-adverse-effect-level (LOAEL) [48].
