  1. The detection frequency for the summed variables was defined as the proportion of individuals with at least one detected compound
  2. DEP Diethyl phosphate; DETP Diethyl thiophosphate; DMTP Dimethyl thiophosphate; DMDTP Dimethyl dithiophosphate; DEAMPY 2-diethylamino-6-methyl-4-pyrimidinol; IMPY 2-isopropyl-4-methyl-6-hydroxypyrimidine; PNP para-nitrophenol; TCPY 3,5,6-trichloro-2-pyridinol; sumDEP DEP + DETP; sumDMP DMTP + DMDTP; sumDAP sumDEP + sumDMP; sumOP DEAMPY + IMPY + PNP + TCPy
  3. The limit of determination was 10 μg/L for DEP, 2.3 μg/L for DETP, 1.6 μg/L for DMTP, 1.6 μg/L for DMDTP, 0.8 μg/L for TCPY, 0.8 μg/L for PNP, 1.6 μg/L for DEAMPY, and 1.6 μg/L for IMPY.
  4. LOD limit of determination
  5. Min minimum value
  6. Max maximum value
  7. GM geometric mean
