GSD, geometric standard deviation.
Multiple imputation (n = 10 imputed datasets) was used to impute air-sampling data below detection limits.
Number of measurements representing the TWA recorded for each paint task. Because of sampling pump malfunction, seven samples collected in NC and one sample collected in WA were excluded.
