a1-OHPG levels in urine were obtained from 108 participants in winter and 109 participants in summer. The biomarker levels are presented in following units: 1-OHPG, pmol/ml; creatinine, mg/dl; creatinine-adjusted 1-OHPG, μmol/molCr.

bP-value for difference in Cr-adjusted 1-OHPG levels in winter and summer (in logarithmic scale), calculated using paired t-tests. The number of participant with paired results was 106.

1-OHPG, 1-hydroxypyrene glucuronide; Cr, creatinine.
