Toxicologic Units

  • Jeannee K. Yermakoff
Part of the Life Science Monographs book series (LSMO)


Toxicologic units have become an integral part of communicating information for the toxicologist. In human and animal studies, these units are used to conveniently summarize study results as a single value (e.g., the SMR and LD50, respectively). When describing exposure to a chemical, toxicologic units provide an indication of the purpose for selection of a given dose (e.g., the MTD) or an acceptable level of human exposure (e.g., the TLV). However, effective communication using this unique vocabulary of toxicologic abbreviations requires that the definitions be clearly understood. This is particularly important when these toxicologic units are used to communicate toxicologic information to individuals outside the realm of the practicing toxicologist.
