Phthalate metabolites have short half-lives. To gain insight into long-term exposure, longitudinal measures in biospecimens are preferred. House dust and silicone wristbands are the most common environmental media analyzed, but other media (such as air samplers and soil) have also been used. For more details see Exposure to Phthalates.
Biospecimens: Volume requirements - typically 0.1-1.0 mL of urine
Core analytes (subset of analytes that will be measured and reported by any targeted HHEAR Lab Hub that provides Phthalate analysis in urine):
- Mono-benzyl phthalate
- Mono-n-butyl phthalate
- Mono-carboxy isononyl phthalate
- Mono-carboxy isooctyl phthalate
- Mono-(3-carboxypropyl) phthalate (multiple)
- Mono-(2-ethyl-5-carboxypentyl) phthalate
