Fig 2.
Left-skewed distribution of TWA samples from workers in the study (N = 12, k = 120).
Data in the table represent TWAs. EEL–environmental exposure limit.
Table 2.
The means and ranges of recorded PM10 concentrations from 12 sampled workers (k = 10 tests from each worker) (sampling started in the middle of November 2018 and ended in the middle of March 2019).
Fig 3.
ANOVA of TWA concentrations between workers.
Data in the table represent TWAs. *—significant difference from worker 3; #—significant difference from worker 7 (both Tukey-Kramer test). Box with whiskers cover 95% values.
Fig 4.
ANOVA of TWA concentrations between weekdays.
Data in the table represent TWAs. Box with whiskers cover 95% values.
Fig 5.
The smoothed trend of TWA concentrations over the entire period from all subjects.
Grey dots are actual TWA concentrations for a single day; black line is a smoothed trend.
