<strong>Toxicology</strong>（毒理学）是一门研究化学、物理或生物因子对活体生物产生不良效应（Adverse Effects）的学科。它是生物学、化学和医学的交叉领域，核心格言源自 <strong>[[Paracelsus]]</strong> 的名言：“剂量决定毒性” (The dose makes the poison)。毒理学不仅研究毒物的<strong>[[Toxicokinetics]] (毒代动力学)</strong>（即毒物如何进入、分布、代谢和排出）和<strong>[[Toxicodynamics]] (毒效动力学)</strong>（即毒物如何损伤机体），还包括中毒的临床救治（<strong>[[Clinical Toxicology]]</strong>）、环境影响评估（<strong>[[Ecotoxicology]]</strong>）以及法律鉴定（<strong>[[Forensic Toxicology]]</strong>）。<br />

<p style="margin: 15px 0; text-align: justify;"><br />
<strong>"Sola dosis facit venenum"</strong>（唯有剂量能区分毒药与良药）。这一原则构成了毒理学的基础。通过绘制<strong>剂量-反应曲线 (Dose-Response Curve)</strong>，毒理学家确定了物质的安全阈值和致死水平。<br />
