毒理学是对各种级别的天然和合成化学物质的有害影响的科学理解，无论是大规模的环境污染物还是小规模的致癌物，随着时间的推移，这种危害会逐渐增加。该领域涉及外部因素如何影响细胞的遗传结构。USU的毒理学家正在研究疾病的基因组学，癌症预防，空气污染的机理等方面的研究。该领域的科学家专注于影响环境的毒素。他们的研究旨在恢复生态系统，消除有毒废物，并减少人类和动物对环境毒素的接触。此外，USU的科学家是最早使用天然真菌消化化学废物并使之排毒的人之一。毒理学是一个跨部门的学位，学生可以通过多个部门中的一个加入该计划。学
Toxicology is the scientific understanding of the harmful effects of natural and synthetic chemicals at all levels – whether large-scale environmental pollutants or small-scale carcinogens – that have an incremental effect over time.This area deals with how external agents affect the genetic structure of cells. Toxicologists at USU are developing research on the genomics of disease, cancer prevention, the mechanisms of air pollution, and more.Scientists working in this area are focused on toxins that affect the environment. Their research aims to restore ecosystems, remove toxic waste, and reduce human and animal exposure to environmental toxins. Additionally, USU scientists were among the first to use a naturally occurring fungus to digest and detoxify chemical waste.Toxicology is an interdepartmental degree where students affiliate with the program through one of several departments. While students are housed in the same department as their major professor, their committees are comprised of faculty from a minimum of two to three departments, giving them multiple perspectives on their research.
