Study Notes
Endocrine Disruption and Environmental Pesticides
- The endocrine system includes glands such as hypothalamus, pituitary, thyroid, and pancreas, which synthesize and secrete hormones to control body functions.
- Endocrine disruption can occur through the alteration of gland or target cell function, metabolism of hormones, or mimicry of natural hormones by foreign substances.
- Pesticides have been identified as environmental endocrine disruptors (EEDs), with some affecting thyroid hormones and others exhibiting estrogenic or androgenic effects.
- Triclosan, a common antibacterial agent found in personal care products, has been linked to estrogenic effects in fish and is present in US water resources.
- Exposure to xenoestrogens like o,- DDT has been linked to male-to-female sex reversal in fish, while atrazine has induced hermaphroditism and demasculinization in frogs.
- Nonylphenol, found in household cleaning products, has been associated with long-term and transgenerational effects in oysters, including changes in sex ratio and gamete viability.
- Polycyclic musks, used in perfumes and soaps, have been found to bioaccumulate in fish and exhibit antiestrogenic effects in aquatic biota.
- In vitro assays are used to test for endocrine disruptions caused by environmental pesticides and other substances.
