Table 1.

Concentration of TCE and fat in breast milk (n=20).^a

Milk Concentration	LOD^b	Mean^c	SD^c	Median	Range
ng TCE/ mL milk	1.5	1.5	1.1	ND	ND-6.0
ng TCE/ g milk	1.5	1.5	1.2	ND	ND-6.4
ng TCE/ g fat	9.3	22.0	25.9	ND	ND-95.6
g fat/ L milk		56.8	24.5	56.4	16.9–90.4

Detection frequency was 35%. These results do not include the duplicate samples provided by two mothers.

Fat was quantified in all breast milk samples.

Values below LOD were assumed to equal the LOD divided by square root of 2 (27).
