The object of the present monograph is to discuss the goals of health-oriented regulation of the production, application and utilization of substances with the potential to exhibit their action both later in the life of the present generation and in subsequent generations that have not been directly exposed to the chemicals themselves. The book inquires into changes in the reproductive function and the ageing processes of the cardio-vascular system resulting from exposure to chemical compounds; it also looks at some dimensions of chemical carcinogenesis.
