Chemicals that fool the body
- The body runs on hormones 激素 — chemical messengers.
- They control growth, reproduction, and development.
- Some pollutants can interfere with these signals.
- These are endocrine disruptors 内分泌干扰物.
欺骗身体的化学物质
- 身体靠激素(hormones)运转——化学信使。
- 它们控制生长、繁殖和发育。
- 有些污染物能干扰这些信号。
- 这些是内分泌干扰物(endocrine disruptors)。
How they trick the body
- A disruptor's shape can copy a natural hormone.
- It slots into the hormone's receptor 受体 like a fake key.
- The body reads it as a real signal — but it is false.
- Or it can block the receptor, so the real hormone can't act.
它们如何欺骗身体
- 一个干扰物的形状能复制一种天然激素。
- 它像一把假钥匙插入激素的受体(receptor)。
- 身体把它读作真实的信号——但它是假的。
- 或者它能堵住受体,让真激素无法起作用。
An endocrine disruptor is a chemical that… · 一种内分泌干扰物是一种化学物质,它……
An endocrine disruptor interferes with hormones — the chemical messengers that control the body. · 一种内分泌干扰物干扰激素——控制身体的化学信使。
Where they come from
- Some are found in certain plastics 塑料.
- Others come from pesticides and industrial chemicals.
- They wash into rivers and enter the food and water we use.
- From there they build up in animals and people.
它们从哪里来
- 有些存在于某些塑料(plastics)中。
- 其他来自农药和工业化学品。
- 它们冲入河流,进入我们使用的食物和水。
- 从那里它们在动物和人体内积累。

Follow a chemical that copies a hormone and sends the body false signals. · 跟随一种复制激素并给身体发送假信号的化学物质。
Many endocrine disruptors work by… · 许多内分泌干扰物通过以下方式起作用……
Their shape copies a hormone, so they slot into its receptor and send false signals. · 它们的形状复制一种激素,所以它们插入它的受体并发送假信号。
Endocrine disruptors are found in some pesticides and in certain ____. · 内分泌干扰物存在于一些农药和某些____中。
Some plastics and pesticides contain chemicals that act as endocrine disruptors. · 一些塑料和农药含有充当内分泌干扰物的化学物质。
Why they are dangerous
- Hormones work in tiny amounts, so even a trace can cause harm.
- Disruptors damage reproduction 繁殖 and development.
- They can cause defects in young animals and people.
- Whole populations of frogs and fish have been affected.
为什么它们危险
- 激素以微量起作用,所以即使微量也能造成伤害。
- 干扰物损害繁殖(reproduction)和发育。
- 它们能造成幼小动物和人的缺陷。
- 整个种群的青蛙和鱼已受到影响。
Endocrine disruptors can cause harm even at very low concentrations. · 内分泌干扰物即使在很低的浓度下也能造成伤害。
Hormones work in tiny amounts, so even a trace of a disruptor can throw the system off. · 激素以微量起作用,所以即使微量的干扰物也能使系统失调。
Select all · 所有 harms linked to endocrine disruptors. · 选出与内分泌干扰物有关的所有伤害。
Disruptors harm reproduction, development, and growth. They weaken the body, not strengthen it. · 干扰物损害繁殖、发育和生长。它们削弱身体,而不是加强它。
What makes endocrine disruptors so dangerous is that a tiny dose can matter. Most poisons need a large dose to harm you — but hormones already work at trace levels, so a chemical that mimics one can throw the whole system off even in minute amounts. That breaks the usual "the dose makes the poison" rule, and makes them hard to regulate.
使内分泌干扰物如此危险的是微小的剂量就能起作用。大多数毒物需要大剂量才能伤害你——但激素本来就在微量水平起作用,所以一种模仿激素的化学物质即使在极微量下也能使整个系统失调。那打破了通常的"剂量造就毒物"规则,使它们难以监管。
Frogs in a polluted pond:
- A pesticide washes off nearby fields into the pond at very low levels.
- The chemical mimics a hormone, slotting into the frogs' receptors and scrambling their development.
- The next generation of tadpoles grows up with deformities and cannot breed properly — a whole population harmed by a trace of a hormone-mimicking chemical.
污染池塘里的青蛙:
- 一种农药从附近的田地以很低的水平冲入池塘。
- 化学物质模仿一种激素,插入青蛙的受体并扰乱它们的发育。
- 下一代蝌蚪长大时带有畸形,无法正常繁殖——整个种群被微量的模仿激素的化学物质伤害。
Endocrine disruptors are pollutants that interfere with the body's hormones, often by mimicking them and slotting into a receptor to send false signals. They come from some plastics, pesticides, and industrial chemicals. Because hormones act in tiny amounts, disruptors can harm reproduction and development even at very low concentrations.
内分泌干扰物是干扰身体激素的污染物,常常通过模仿它们并插入受体来发送假信号。它们来自一些塑料、农药和工业化学品。因为激素以微量起作用,干扰物即使在很低的浓度下也能损害繁殖和发育。
