Air toxic risk assessment: science vs. policy in regulatory estimates for outdoor stationary sources L.B. Gratt IWG Corp., San Diego, California 92101, USA INTRODUCTION Concern for human health and the environment has resulted in risk assessment use in regulatory processes. These risk assessments involve complex, multidisciplinary technologies treated in an approximate and, oftentimes, oversimplified manner using conservative values. This paper addresses implications of some assumptions for using air toxic human health risk assessments to develop regulatory strategies for stationary sources. Risk is defined as the potential for realization of unwanted, adverse consequences to human life, health, property, or the environment. Estimation of risk is usually based on the expected value of the conditional probability of the event occurring times the expected consequence of the event given that it has occurred [1]. Risk assessments are often performed t
