摘要

The problem of estimating potential health impacts from the sulfur emissions from large, coal-fired plants is used as a vehicle from which to develop and demonstrate a variety of techniques for characterizing and dealing with uncertainties in risk assessment. Psychological literature on expert judgement is reviewed and a protocol for eliciting judgment from experts about the value of certain coefficients in the form of subjective probability distributions is developed. Long-range, sulfur mass balance models are constructed and analyzed to determine the relative impact of the uncertainty expressed by individual experts and the variation between experts on conclusions concerning long-range, annual average sulfur mass balance in power plant plumes. Judgments of leading health effects experts concerning the possible health impacts of sulfur air pollutants of coal-fired plants are included. A set of quantitative health damage models is constructed and compared and a set of decision-theoretic concepts is developed. It is found that in estimating the annual sulfur mass balance in power plant plumes, uncertainty expressed by individual experts is always comparable to and sometimes greater than the uncertainty which results from differences between experts.
