Hazardous Substances And Human Health

In fact, with the control and containment of most infectious conditions and diseases of the past millennium having been achieved in most developed countries, and with the resultant increase in life expectancies, much more attention seems to have shifted to degenerative health problems. Many of the degenerative health conditions have been linked to thousands of chemicals regularly encountered in human living and occupational/work environments. It is important, therefore, that human health risk assessments are undertaken on a consistent basis - in order to determine the potential impacts of the target chemicals on public health.

There is widespread public concern about hazardous chemicals that are contained in air, soil, water and food. Policy has therefore adopted a series of laws and regulations concerning emissions into and concentration levels in different media including food. As policy makers do not only have to consider the protection of the environment but also need to ensure a well-functioning economy at the same time, these limit or target values need to be set in a balanced way. The main problem, however, is to compare the costs for achieving these targets with the benefits to society by having a smaller exposure to hazardous substances (cost-benefit analysis). This book sets out to improve the reliability of cost-benefit analyses particularly of hazardous substances present in air, water, soil and food. It suggests that the human health risk assessment of chemicals is performed in a bottom-up analysis, i.e., following a spatially resolved multimedia modelling approach. In order to support cost-benefit analyses, the approach is accompanied by monetary valuation of human health impacts, yielding so-called external costs. Results for selected priority metals show that these external costs are small compared to those by the classical air pollutants and involve rather long time horizons touching on the aspect of intergenerational equity within sustainable development. When including further hazardous substances, the total external costs attributable to contaminants are expected to be more substantial.

The National Human Monitoring Program (NHMP) identifies concentrations of specific chemicals in human tissues, including toxicologic testing and risk assessment determinations. This volume evaluates the current activities of the NHMP; identifies important scientific, technical, and programmatic issues; and makes recommendations regarding the design of the program and use of its products.

This book describes the association between hazardous waste and human health and the role of public health programs in addressing this association. Several themes connect the material as a coherent body of knowledge. It contains up-to-date depictions of the human health impacts of hazardous waste and attendant public health responses. It defines the term "public health'" and its role at local and national levels.

Contains information about 80 hazardous substances, including what each substance is, how exposure may occur and possible health effects, and medical tests available to determine exposure.
