This book educates and instruct students, industrial hygienists, and occupational health specialists in the understanding, program development, and application of Total Worker Exposure concepts. Industrial hygienists and occupational health specialists have the expertise, training, and knowledge to have a significant impact in this area, but they often lack an understanding of how to apply Total Worker Exposure concepts in their own workplaces. This book defines the scope of Total Worker Exposure specifically, and provides concrete approaches, solutions, tools, and case studies to help professionals apply these concepts within their areas of influence. Through these tools and technologies, workplaces and industrial hygienists can make a distinct contribution to both worker and public health by helping to address and manage this relevant part of the external exposome. Chapters one through four focus on introducing and discussing the published science related to Total Worker Exposure, how it is defined, and the stressors it encompasses. Chapters five through nine discuss delineating the role of Total Worker Exposure specifically (compared to efforts focused on broader health or on total exposures to the public, as well as the important science of cumulative risk assessment and how it can be applied to Total Worker Exposure). Chapters nine through fourteen address additional topics such as case studies, ethics, data gaps, and data analysis.
