Table 1 Distribution of nighttime cumulative amounts of MP and EP metabolites of organophosphorus pesticides measured in the urine of children

From: Determination of no-observed effect level (NOEL)-biomarker equivalents to interpret biomonitoring data for organophosphorus pesticides in children

Metabolite Total amounts in nighttime collections (nmol/kg body weight)a
  Geometric mean Minimum Maximum Percentiles
     5 25 50 75 95
Methylphosphates 2.05 0.006 75.4 0.201 0.849 2.10 5.12 15.8
Ethylphosphates 0.233 0.004 7.34 0.031 0.114 0.241 0.547 1.37
Methyl + ethylphosphates 2.43 0.011 77.0 0.306 1.09 2.39 5.66 17.3
  1. Note: Methyl phosphates = the sum of dimethyl dithiophosphates (DMDTP), dimethyl thiophosphates (DMTP) and dimethyl phosphates (DMP); ethyl phosphates = the sum of diethyl dithiophosphates (DEDTP), diethyl thiophosphates (DETP) and diethyl phosphates (DEP).
  2. a Incomplete urine voids were excluded.
