New Toxicology Tools and the Emerging Paradigm Shift in Environmental Health Decision-Making

Abstract

Many of the statutes that regulate chemicals in the environment place a high priority on the protection of public health and the environment. Moving away from the sole reliance on traditional approaches and information sources used in hazard, exposure, and risk assessment, toward the more expansive use of rapidly acquired chemical information via <i>in vitro</i>, <i>in silico</i>, and targeted testing strategies will require careful consideration of the information needed and values considerations associated with a particular decision. In this commentary, we explore the ability and feasibility of using emerging data streams, particularly those that allow for the rapid testing of a large number of chemicals across numerous biological targets, to shift the chemical testing paradigm to one in which potentially harmful chemicals are more rapidly identified, prioritized, and addressed. Such a paradigm shift could ultimately save financial and natural resources while ensuring and preserving the protection of public health. https://doi.org/10.1289/EHP4745.
