MillerJD_WB_rotator_data.csv
Description: These data correspond to values plotted in Figure 2 and Figure S1 in the paper. All other figures represent derivations of this dataset, as described in the paper. 

This dataset has the following columns:

Replicate: Identification number for the wristband segment sample replicate (1, 2 or 3)	
Time rotating: number of days the wristband was exposed to the ambient indoor air.
Rotator Speed: tangential speed of the wristband,in units of meters per second, as calculated at the distal end using the dimensions shown in Figure 1.
Chemical ID attributes starting with "2IPPDPP": The attribute acronyms are defined in Supplementary Information Table S1. The values correspond to the chemical concentration in units ng per gram wristband.



MillerJD_model_parameters.csv
These data represent optimized parameters derived from regression model fits of Eq. 4 to wristband concentration data. The model equation for each chemical are plotted (dotted lines) in Figure 2 and Figure S1 in the paper. Parameters are only included for 19 modeled chemicals shown in Figure S1. 

This dataset has the following columns:

Rotator Speed: tangential speed of the wristband, in units of meters per second
Model parameter: model fitting parameter from the regression (xs,eq or ke); Initial concentration value in wristband (xs,t=0)
Parameter units: units of the model parameter 
Chemical ID attributes starting with "TEP": Value of the model parameter; the attribute acronyms are defined in Supplementary Information Table S1.
