EWAS in toxicology often focus on a variety of chemical exposures, including industrial pollutants, pesticides, pharmaceuticals, heavy metals, and endocrine disruptors. These studies aim to uncover how these substances influence epigenetic patterns and, subsequently, gene expression and health outcomes. For instance, exposure to bisphenol A (BPA), a common endocrine disruptor, has been linked to changes in DNA methylation patterns that may contribute to breast cancer risk.
