This study determined normal levels of pentachlorophenol (PCP) in urine from Saskatchewan residents. The average daily excretion of PCP was found to be 4.3 nmol/day, with concentrations ranging from 0.05 to 3.6 ng/ml.

Area of Science:

  • Environmental Health
  • Toxicology
  • Human Biomonitoring

Background:

  • Pentachlorophenol (PCP) is a widely used pesticide and wood preservative.
  • Human exposure to PCP can occur through various environmental routes.
  • Establishing normal ranges for PCP is crucial for assessing population exposure and health risks.

Purpose of the Study:

  • To determine the normal range of pentachlorophenol (PCP) concentrations in 24-hour urine samples from individuals in Saskatchewan.
  • To establish the average daily excretion of PCP in a general population sample.

Main Methods:

  • Analysis of 69 urine samples from 26 males and 43 females aged 6-87 years.
  • Quantification of urinary PCP using gas chromatography-mass spectrometry (GC-MS) with stable isotope dilution.

  • Measurement of 24-hour urine collections to determine daily excretion rates.

    • Main Results:

    • Normal urinary PCP concentrations ranged from 0.05 to 3.6 ng/ml.
    • The average daily excretion of PCP was determined to be 4.3 nmol/day.
    • Data collected from both rural and urban regions of Saskatchewan.

    Conclusions:

    • The study provides reference values for PCP levels in a Canadian population.
    • These findings can aid in the biomonitoring of PCP exposure and potential health effects.
    • Urinary PCP levels reflect recent exposure and contribute to understanding environmental contamination.
