Di-(2-Ethylhexyl) Phthalate (DEHP) in House Dust in Canadian Homes: Behaviors and Associations with Housing Characteristics and Consumer Products

Table 2

Concentrations of DEHP measured in house dust (μg/g) and corresponding DEHP metabolite concentration (ng/mL) measured in urine, both sampled at 3 months of age.

Phthalate and metabolites	N	Min	5th percentile	Median	95th percentile	Max	Geomean
DEHP in dust (μg/g)	726	9.6	65.3	231.9	858.5	2675.3	232.9
MEHP (ng/mL)	354	0.0007	0.06	0.6	5.7	59.3	0.6
MEOHP (ng/mL)	354	0.05	0.3	1.5	5.9	30.7	1.3
MEHHP (ng/mL)	351	0.07	0.3	1.5	8.6	43.6	1.5
∑DEHP in urine (nmol/mL)	—	0.0005	0.0032	0.01	0.074	0.3	0.02

Notes: MEHP is the primary DEHP metabolite, and MEOHP and MEHHP are the secondary metabolites measured in urine samples. ∑DEHP in urine indicates the molar sum of these three DEHP metabolites in urine and was calculated using the formula .
