Urinary concentrations collected from farm family members in the day or days immediately after application of 2,4-D fell below the applicable acute BE values.
We assessed exposure using the average of two phthalate metabolite spot-urine concentrations collected from the mothers in the first and third pregnancy trimesters (creatinine-adjusted, n = 391).
Average indoor air concentrations collected from urban, suburban, and rural residences between 1990 (after the 1989 ban on hairspray) and 2005 ranged from 0.4 to 3.5 μg/m (Dawson and McAlary 2009).
Trough concentrations collected from the patient medical records were assumed to be measured 12 h after dose, but may have been measured after intake of the subsequent morning dose in some cases.
The mean SO2, NO, NO2, CO, and O3 concentrations collected from the portable instrument were near or below the instrument's detection limit.> -wrap-foot>> -wrap-foot> SF Sterling Forest, GSP Garden State Parkway, GWB George Washington Bridge.
Because we used point estimates for all exposure factors, variability in DDT concentrations collected from each geographical area is the only source of variability in the distributions of estimated uptake.
We validated the model with home out-door NO2 concentrations collected from a subset of the subjects; the model had an R between 0.77 and 0.86, depending on area (Liu LJ, Keidel D, Gemperli A, Hazenkamp M, Bayer L, Rochat T, et al., unpublished data).
The loss of this assay kit and the finding that serum vitamin B-12 concentrations collected from NHANES III (1991 1994) to NHANES 2006 had not changed appreciably (1) resulted in a decision to drop measures of vitamin B-12 status after NHANES 2006.
Having shown that GBP BADAN could be used to measure changes in ASL glucose concentrations collected from Calu-3 monolayers, we investigated whether the GBP assay could be used to detect dynamic changes in situ, in response to elevated basolateral glucose, by applying GBP BADAN directly to the apical surface of primary HBECs.
