Regulatory agencies are required to mitigate human and ecological exposure to toxic chemicals of concern. In order to meet this demand, chemical drivers of toxicity and accurate exposure pathways must be identified. Though mixtures are complex systems, it has been postulated that the bioavailable fraction of mixtures is linked to toxicity. Applying additional stressors to chemical mixtures will likely transform the composition of the bioavailable fraction and induce differential toxicological responses. In order to more accurately characterize exposure, regulatory agencies need experimental approaches that can determine the effect of natural/remediation processes on the bioavailable fraction of chemical mixtures and mixture toxicity.
