This chapter highlights various aspects of miRNAs, including their description, history, biological significance, expression and processing, and their interactions with their mRNA targets. It discusses the current state of knowledge regarding the effect of various environmental toxicants on miRNA profiles. A comprehensive literature search revealed that for many environmental toxicants, there is no information or very little information available in terms of their effects on miRNA expression. The chemicals are divided into four major classes and are notable for their toxic effects, known or suspected roles in human disease development, and potential for widespread exposure. The chapter includes studies that represent primary areas of research examining miRNA alterations associated with each toxicant. It focuses on those studies that provide insight into the mechanisms involved in miRNA dysregulation and how such perturbation may lead to disease development.
