What are examples of endocrine disruptors?
These include polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs), and dixons. Other examples of endocrine disruptors include bisphenol A (BPA) from plastics, dichlorodiphenyltrichloroethane (DDT) from pesticides, vinclozolin from fungizides, and diethylstilbestrol (DES) from pharmaceutical agents.
How does phthalates affect the human body?
Phthalates, a family of industrial chemicals used to soften polyvinyl chloride (PVC) plastic and as solvents in cosmetics and other consumer products, can damage the liver, kidneys, lungs, and reproductive system.
What type of toxins are known endocrine disruptors?
The group of molecules identified as endocrine disruptors is highly heterogeneous and includes synthetic chemicals used as industrial solvents/lubricants and their byproducts [polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs), dioxins], plastics [bisphenol A (BPA)], plasticizers (phthalates), pesticides …
What do endocrine disruptors cause?
Other endocrine disruptors block the effects of a hormone from certain receptors (e.g. growth hormones required for normal development). Still others directly stimulate or inhibit the endocrine system and cause overproduction or underproduction of hormones (e.g. an over or underactive thyroid).
What is an endocrine disruptor quizlet?
endocrine disruptor. a (sometimes) synthetic chemical that, when absorbed into the body, either mimics or blocks hormones and disrupts the body’s normal functions (either antagonists or agonists)
What is a phthalate and why is it bad?
Phthalates are a group of chemicals used to make plastics more durable. They are often called plasticizers. Some phthalates are used to help dissolve other materials. Phthalates are in hundreds of products, such as vinyl flooring, lubricating oils, and personal-care products (soaps, shampoos, hair sprays).
What are phthalate chemicals?
Which of the following best describes the action of an endocrine disruptor?
Which of the following best describes the action of an endocrine disruptor? An endocrine disruptor blocks the receptor protein binding site of a hormone so that the cell cannot receive a signal.

What products have phthalates?
What are the effects of phthalates on the endocrine system?
Despite the short half-lives in tissues, chronic exposure to phthalates will adversely influence the endocrine system and functioning of multiple organs, which has negative long-term impacts on the success of pregnancy, child growth and development, and reproductive systems in both young children and adolescents.
Which of the following chemicals is an endocrine disruptor?
Chemicals that are known endocrine disruptors include diethylstilbestrol (the synthetic estrogen DES), dioxin and dioxin-like compounds, polychlorinated biphenyls (PCBs), DDT, and some other pesticides.
What are phthalates and why are they harmful?
Abstract Phthalates are a series of widely used chemicals that demonstrate to be endocrine disruptors and are detrimental to human health. Phthalates can be found in most products that have contact with plastics during producing, packaging, or delivering.
Are plastics endocrine disruptors?
Plasticizers such as phthalate esters, because of their anti-androgen and estrogen-like activity, are indicated as major endocrine disruptors [8].
