The National Library of Medicine's (NLM) Division of Specialized Information Services (SIS) Toxicology and Environmental Health Information Program is responsible for the management of the online Hazardous Substances Data Bank (HSDB). HSDB, a part of NLM's Toxicology Data Network (TOXNET(®)), is a file of chemical/substance information with one record for each specific chemical or substance, or for a category of chemicals or substances. Like the rest of TOXNET's databases and other resources, HSDB is available online at no cost to global users. HSDB has approximately 5600 chemicals and substances, with a focus on toxicology information and also on human exposure, industrial hygiene, emergency handling procedures, environmental fate, regulatory requirements, and related areas of likely interest to HSDB users. All data are from a core set of books, government documents, technical reports, selected primary journal literature, and other online sources of information, with a goal of linking the HSDB content to as much publicly available information as possible. HSDB's content is peer-reviewed by the Scientific Review Panel, a group of experts in the areas covering the scope of HSDB content. Recent enhancements include the addition of chemical structures to HSDB records, the addition of new subfields such as age groups for human data, more occupational exposure standards, and the addition of information on numerous nanomaterials. Examples of future plans include providing more exposure-related information, e.g., uses of a chemical or substance in consumer products; the addition of information summaries aimed towards consumers and other members of the public wanting to learn about a chemical or substance; more visual content such as diagrams (images) of the pathways of metabolism of a substance; and enhanced search features and navigation.

美国国家医学图书馆 (NLM) 的有害物质数据库 (HSDB)：背景、近期改进和未来计划。

国家医学图书馆 (NLM) 专业信息服务部 (SIS) 毒理学和环境健康信息计划负责管理在线有害物质数据库 (HSDB)。HSDB 是 NLM 毒理学数据网络 (TOXNET(®)) 的一部分，是一个化学/物质信息文件，每个特定化学品或物质或一类化学品或物质都有一个记录。与 TOXNET 的其余数据库和其他资源一样，HSDB 可供全球用户免费在线使用。HSDB 拥有大约 5600 种化学品和物质，重点关注毒理学信息以及人类暴露、工业卫生、紧急处理程序、环境归宿、监管要求以及 HSDB 用户可能感兴趣的相关领域。所有数据都来自一组核心书籍、政府文件、技术报告、选定的主要期刊文献和其他在线信息来源，目的是将 HSDB 内容与尽可能多的公开信息联系起来。HSDB 的内容由科学审查小组（Scientific Review Panel）进行同行审查，该小组由涵盖 HSDB 内容范围的领域的专家组成。最近的改进包括向 HSDB 记录添加化学结构、添加新的子字段，例如人类数据的年龄组、更多的职业暴露标准，以及添加有关众多纳米材料的信息。未来计划的例子包括提供更多与暴露相关的信息，例如消费品中化学品或物质的使用；增加了针对想要了解化学品或物质的消费者和其他公众成员的信息摘要；更多视觉内容，例如物质代谢途径的图表（图像）；以及增强的搜索功能和导航。
