How scientists accurately measure plastic chemicals in your pee
Determination of bisphenol A-glucuronide in human urine using ultrahigh-pressure liquid chromatography/tandem mass spectrometry.

Scientists made a super-precise test to find tiny amounts of a plastic chemical (BPA) in urine by measuring its broken-down form, so they don't get fooled by BPA from lab tools.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

When plastic containers are heated or scratched, chemicals called bisphenol A and phthalates can transfer into food and drinks. These same chemicals can be found unchanged in human urine after consumption.
A highly precise laboratory technique can measure a specific breakdown product of bisphenol A in human urine with minimal error and without confusion from environmental contaminants, allowing researchers to accurately track human exposure levels in large populations.
