Endocrine Disruptors - AP Environmental Science
- How do endocrine disruptors interfere with estrogen?
- They can mimic or block estrogen receptors. Bind to hormone receptors or alter hormone levels.
- What is a known endocrine disruptor in flame retardants?
- Polybrominated diphenyl ethers (PBDEs). Used in electronics and furniture to prevent fires.
- Which endocrine disruptor is often used as a plasticizer?
- Phthalates. Chemical additives that make plastics flexible.
- What is a common property of endocrine disruptors?
- Hormone mimicry or blockage. Chemicals that interfere with natural hormone function.
- Identify a common source of endocrine disruptors.
- Pesticides. Widely used chemicals that often contain hormone-disrupting compounds.
- What is the environmental persistence of many endocrine disruptors?
- High environmental persistence. Many resist breakdown and accumulate in ecosystems.
- Which endocrine disruptor can accumulate in fatty tissue?
- Dioxins. Lipophilic compounds concentrate in body fat stores.
- Identify a food product that could contain endocrine disruptors.
- Processed foods with additives. Food packaging and preservatives can contain hormone disruptors.
- Name the endocrine disruptor associated with antifungal agents.
- Triclosan. Antimicrobial agent that interferes with thyroid hormones.
- How do endocrine disruptors affect the immune system?
- They can weaken immune responses. Hormonal disruption affects immune cell function.
- Name an endocrine disruptor found in plastics.
- Bisphenol A (BPA). Common plastic additive that mimics estrogen in the body.
- Which endocrine disruptor is linked to neurological disorders?
- Lead. Heavy metal that disrupts brain development and function.
- Which endocrine disruptor is found in non-stick cookware?
- Perfluorinated chemicals (PFCs). Persistent chemicals used for stain and water resistance.
- What is a common effect of endocrine disruptors on the reproductive system?
- Infertility. Hormonal disruption affects reproductive organ function.
- Name an endocrine disruptor associated with antibacterial soaps.
- Triclosan. Antimicrobial agent that affects thyroid and reproductive hormones.
- What is the impact of endocrine disruptors on puberty?
- They can cause early or delayed puberty. Disrupts hormones that control sexual maturation timing.
- Which chemical is both a pesticide and an endocrine disruptor?
- Atrazine. Herbicide that interferes with reproductive hormones.
- Identify an endocrine disruptor used in UV filters.
- Oxybenzone. Sunscreen ingredient that mimics estrogen.
- Identify one agricultural product that can contain endocrine disruptors.
- Herbicides. Weed killers often contain hormone-disrupting chemicals.
- Which endocrine disruptor is often found in personal care products?
- Phthalates. Used as plastic softeners in cosmetics and fragrances.
- What is the effect of endocrine disruptors on wildlife?
- They can cause reproductive and developmental issues. Hormonal interference affects growth and breeding success.
- List a health effect of endocrine disruptors on children.
- Developmental delays. Hormonal interference during critical growth periods.
- Name a natural source of endocrine disruptors.
- Phytoestrogens in plants. Plant compounds that can mimic human hormones.
- What is the impact of endocrine disruptors on thyroid function?
- They can cause hyperthyroidism or hypothyroidism. Disrupts thyroid hormone production and regulation.
- What is an endocrine disruptor?
- A chemical that interferes with hormone systems. Disrupts normal hormone signaling pathways in the body.
- Identify a synthetic hormone that acts as an endocrine disruptor.
- Diethylstilbestrol (DES). Pharmaceutical estrogen that caused reproductive harm.
- What is the effect of endocrine disruptors on fish populations?
- Feminization of male fish. Estrogen-like effects alter sexual development in aquatic life.
- Identify an endocrine disruptor found in air pollutants.
- Dioxins. Toxic byproducts of combustion and industrial processes.
- What is a characteristic of endocrine disruptors related to bioaccumulation?
- They tend to bioaccumulate in organisms. Concentrate through food webs, increasing with trophic level.
- What is the potential effect of endocrine disruptors on bone health?
- They may weaken bone structure. Hormonal disruption affects calcium regulation and bone formation.
- What type of disruptor is DDT classified as?
- An endocrine disruptor. Banned pesticide that persists and disrupts hormone function.
- Which endocrine disruptor is linked to liver toxicity?
- Polychlorinated biphenyls (PCBs). Industrial chemicals that cause multiple organ toxicity.
- Which endocrine disruptor is associated with increased cancer risk?
- BPA. Estrogen mimicry linked to hormone-sensitive cancers.
- Which endocrine disruptor is commonly found in industrial solvents?
- Polychlorinated biphenyls (PCBs). Industrial chemicals banned but still present in environment.
- What is the role of endocrine disruptors in obesity?
- They may promote weight gain and metabolic disorders. Disrupt metabolism and fat storage regulation.
- What role do endocrine disruptors play in diabetes?
- They may contribute to insulin resistance. Interfere with hormones that regulate blood sugar.
- What is a method to reduce exposure to endocrine disruptors?
- Use of glass containers instead of plastic. Avoids plastic chemicals that leach into food and drinks.
- How do endocrine disruptors affect human health?
- They may lead to cancer, birth defects, and other disorders. Hormonal disruption affects multiple body systems and development.
- Name an endocrine disruptor that can be found in detergents.
- Alkylphenol ethoxylates. Surfactants in cleaning products that mimic estrogen.
