Although a full-scope toxicology services company, we specialize in interrogating complex chemical mixtures to identify and stratify those chemicals that are most critical and should be the initial focus of concern for potential worker and/or consumer health issues. The significance of this service lies in the fact that the vast majority of the more than 75,000 chemicals in commerce have little, if any, toxicity data available to characterize their potential risk to human health. To address this information gap, StrataTox employs well-developed and state-of-the-art principles in quantitative structure activity relationships (QSAR) coupled with indepth understanding of the pathophysiology of human disease to identify those chemicals that pose the greatest concern to worker or consumer safety. While by itself not sufficient to establish finalized safety or risk guidelines, stratification of risk is immensely helpful in framing tentative safe exposure levels and in directing one's limited resources to most effectively address potential human health concerns associated with these complex exposures. Our ultimate goal is to assist the client with the development of an efficient strategy for assuring workplace safety for their employees and providing safe products to the consumers. In addition to expertise in human health risk assessment and predictive toxicology, StrataTox has consulting agreements with distinguished associates in the following fields of expertise: Exposure assessment and dosimetry Regulatory toxicology Occupational medicine Inhalation toxicology Industrial hygiene Occupational and public health Metabolic disorders Molecular toxicology Food toxicology Environmental toxicology Epidemiology StrataTox also has immediate and preferential access to a certified full-scope analytical and product testing laboratory.
