To regulate new chemical products and pollution from industry and agriculture, government agencies mandate toxicity tests to determine how substances effect the environment. Organizations are prioritizing the development and validation of non-animal testing methods called new approach methodologies (NAMs) to conduct these toxicity tests. NAMs refers to any technology, methodology, or approach that provides information on chemical hazard, exposure, or risk assessment (e.g., "organ-on-a-chip", computer models, in chemico assays). On this page find links to research articles and testing tools provided by federal agencies.

New Approach Methodologies (NAMs) in Ecotoxicology
This bibliography provides citations regarding new approach methodologies (NAMs) used in the field of Ecotoxicology. NAMs are non-animal technologies and approaches used for chemical hazard, exposure and risk assessment testing such as in vitro assays, computational models, cell-based models, and organs-on-chips. The bibliography covers peer-reviewed literature published between 2010 and July 2024.

Alternative Methods Accepted by US Agencies
DHHS. NIEHS. National Toxicology Program Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM).
Find methods and guidance for chemical safety testing that are accepted by U.S. and international regulatory authorities as replacement, reduction, or refinement alternatives to required animal tests. These documents are recommendations that do not necessarily establish legally enforceable responsibilities.
