Major technological advances in the last few years have increased our knowledge of the role that genetics has in occupational diseases and our understanding of genetic components and the interaction between genetics and environmental factors. The use of genetic information, along with all of the other factors that contribute to occupational morbidity and mortality, will play an increasing role in preventing occupational disease. However, the use of genetic information in occupational safety and health research and practice presents both promise and concerns. This book examines the diverse literature and opinions on genetics in the workplace, to highlight important issues, and to provide some considerations for current and future practice.
