More than 200 000 chemicals have been synthesised by human beings, most since the chemical revolution that began during World War 2. Aside from those specifically designated for warfare, the vast majority were designed to improve our health and quality of life, enhance manufacturing and technology, and provide us with toys, clothes, furniture, housing, cleaners, and personal care products. About 1000 are classified as endocrine-disrupting chemicals (EDCs) due to their ability to mimic or block the action of natural hormones and interfere with development and function.

破坏内分泌的化学物质和大脑

自从第二次世界大战期间发生化学革命以来，人类已经合成了20万多种化学物质。除了专门用于战争的化学革命以外，绝大多数化学物质都旨在改善我们的健康和生活质量，提高制造水平和技术水平，并向我们提供玩具，衣服，家具，房屋，清洁剂和个人护理产品。约有1000种被归类为内分泌干扰化学物质（EDC），因为它们具有模仿或阻断天然激素的作用并干扰其发育和功能的能力。
