PATHOLOGY SUPPORT FOR THE NATIONAL INSTITUTE OF ENVIRONMENTAL HEALTH SCIENCES

国家毒理学计划（NTP）是卫生与公众服务部（DHHS）公共卫生服务（PHS）的一项合作努力，旨在协调和管理该部内的毒理学研究和测试活动，向监管和研究机构，科学界和医学界以及公众提供有关潜在危险化学品的科学信息，并加强毒理学的科学基础。这个跨部门项目是世界上最大的动物毒性/致癌性研究科学数据资源之一。国家毒理学规划由国家环境健康科学研究所、国家职业安全与卫生研究所、国家癌症研究所和国家毒理学研究中心的相关毒理学活动组成。国家毒理学规划通过其活动，直接或间接地提供基本科学数据的很大一部分，供其他联邦和州科学和管理机构以及私营部门组织利用，以应对与化学品对人类健康和环境的影响有关的问题。因此，国家毒理学规划在研究和测试化学品和制剂方面的最终作用是保护美国公众的健康，使其免受危险化学品的侵害。

The National Toxicology Program (NTP) was established as a cooperative effort within the Public Health Service (PHS) of the Department of Health and Human Services (DHHS) to coordinate and manage toxicological research and testing activities within the Department, to provide scientific information on potentially hazardous chemicals to regulatory and research agencies, scientific and medical communities, and the public, and to strengthen the science base in toxicology. This interagency program comprises one of the world's largest scientific data resources for animal toxicity/carcinogenicity studies. The NTP consists of the relevant toxicological activities of the National Institute of Environmental Health Sciences, the National Institute for Occupational Safety and Health, the National Cancer Institute, and the National Center for Toxicological Research. Through its activities, the NTP provides either directly or indirectly, a large component of the basic scientific data that other Federal and State scientific and regulatory agencies as well as private sector organizations utilize in responding to issues relevant to the effects of chemicals on human health and the environment. Thus, the ultimate role of the NTP in the research and testing of chemicals and agents is the protection of health of the American public from exposure to hazardous chemicals.
