Complex chemical mixtures impact our health every day. In the United States, and also in Central and Eastern Europe, there are a number of locations where complex chemical mixtures have been released to environmental media. Although exposure to mixtures is common, minimal information exists to quantify these exposures, or to determine their impact on human or ecological receptors. These proceedings present some of the most current research conducted to quantify complex mixtures in the environment and investigate their potential impact on human health. Many of the manuscripts reported in these proceedings represent the most up-to-date measurements of population exposures in Central and Eastern Europe. These studies are of value to health and environmental professionals around the world as they develop strategies for assessing exposures, remediating contaminated environments, and improving public health.
