- •
Few data exist on the temporal variability of urinary pyrethroid metabolites in adults.
- •
3-PBA was frequently detected (74%) in adult urine samples over a six-week period.
- •
ICCs indicated low reliability of repeated 3-PBA measurements in spot urine samples.
- •
Using correction methods to adjust for urine sample dilution increased measurement variability.
