Endocrine disruptor within 48 hours of providing a urine sample had higher levels of diethylhexyl phthalate which is found in polyvinyl chloride, and is used in car interiors. Additives added to plastics during manufacturing may leach into the environment after the plastic item is discarded; additives in microplastics in the ocean leach into ocean water and in plastics in landfills may escape and leach into the soil and then into groundwater. All people are exposed to chemicals with estrogenic effects in their everyday life, because endocrine disrupting chemicals are found in low doses in thousands of products. Chemicals commonly detected in people
