title: Approaches used by the US National Toxicology Program in assessing the toxicity of chemical mixtures.
abstract: The US National Toxicology Program has made a definite commitment towards improving the understanding and predictability of the toxicity of chemical mixtures. The commitment has consisted of a thorough review by the National Research Council of the state of the art of complex mixture testing and strategy for in vivo tests as well as a series of laboratory studies to better characterize the toxicity of selected chemical mixtures and research programmes to improve our ability to predict the toxicological properties of other mixtures.
