Pesticide residues in urine of adults living in the United States : Reference range concentrations.
We measured 12 analytes in urine of 1000 adults living in the United States to establish reference range concentrations for pesticide residues.
We frequently found six of these analytes :
2,5-dichlorophenol (in 98% of adults) ;
2,4-dichlorophenol (in 64%) ;
1-naphthol (in 86%) ;
2-naphthol (in 81%) ;
3,5,6-trichloro-2-pyridinol (in 82%) ;
and pentachlorophenol (in 64%). The 95th percentile concentration (95thPC) for 2,5-dichlorophenol (indicative of p-dichlorobenzene exposure) was 790 mu/liter ;
concentrations ranged up to 8700 mug/liter. 2,4-Dichlorophenol concentrations ranged up to 450 mug/liter, and the 95thPC was 64 mug/liter. 1-Naphthol and 2-naphthol (indicative of naphthalene exposure) had 95thPCs of 43 and 30 mug/liter, respectively ;
concentrations of 1-naphthol ranged up to 2500 mug/liter.
Chlorpyrifos exposure was indicated by 3,5,6-tricholoro-2-pyridinol concentrations of 13 (95thPC) and 77 mug/liter (maximum observed).
Pentachlorophenol had a 95thPC of 8.2 mug/liter.
Other analytes measured included 4-nitrophenol (in 41%) ; 2,4,5. trichlorophenol (in 20%) ; 2,4,6-trichlorophenol (in 9.5%) ; 2,4-dichlorophenoxyacetic acid (in 12%) ; 2. isopropoxyphenol (in 6.8%) ; and 7-carbofuranphenol (in 1.5%). The 95thPCs of these analytes were<6 mug/liter. p-Dichlorobenzene exposure is ubiquitous ; naphthalene and chlorpyrifos are also major sources of pesticide exposure.
Exposure to chlorpyrifos appears to be increasing. (...)
