Endocrine disruptor own hormones. These regulation effects are intertwined so that a hormone that is level affected by another hormone in turn affects the levels of multiple other hormones produced by the body itself, leaving no endogenous hormones or traits affected by them unaffected by endocrine disruptors. Most toxicants, including endocrine disruptors, have been claimed to follow a U-shaped dose response curve. This means that very low and very high levels have more effects than mid-level exposure to a toxicant. Endocrine disrupting effects have been noted in animals exposed to environmentally relevant levels of some chemicals. For example, a common flame retardant,
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.
