Risk Assessment Handbook : Human Health Evaluation

This handbook, Risk Assessment Handbook Volume I - Human Health Evaluation, provides technical guidance to the U.S. Army Corps of Engineers (USACE) risk assessors and risk assessment support personnel for planning, evaluating, and conducting Human Health Risk Assessments (HHRAs) in a phased hazardous, toxic, and radioactive waste (HTRW) response action. The handbook, a compendium to the Risk Assessment Handbook: Volume II - Environmental Evaluation (Engineer Manual (EM) 200-1-4), encourages the use of "good science" within the framework of existing U.S. Environmental Protection Agency (USEPA) risk assessment guidelines. Reference and overview resources: * Required and Related References (Appendix A) * Abbreviations and Acronyms (Appendix B) Risk characterization is a similar process for both human health and Ecological Risk Assessments (ERAs). The fundamental paradigm for human health risk characterization has four phases: (1) hazard identification, (2) dose-response assessment, (3) exposure assessment, and (4) risk characterization. Similarly, the fundamental framework for ecological risk characterization includes four phases: (1) problem formulation, (2) ecological effects characterization, (3) exposure characterization, and (4) risk characterization. This handbook encourages the concurrent assessment of human and ecological risks so that data collection activities are coordinated and risk managers are provided risk characterization results in a timely manner. Risk characterization results for human and ecological receptors should be reasonable and communicated to the risk managers in a clear and unbiased manner to facilitate the making of balanced and informed risk management decisions.Corps of Engineers Washington DC is the author of 'Risk Assessment Handbook : Human Health Evaluation', published 1999 under ISBN 9781423523444 and ISBN 142352344X.
