Assessment of noise related cardiovascular risk: Evaluation of uncertainty in population risk assessment

摘要

Environmental health impact assessment might contribute to public health priority setting and environmental decision-making. Epidemiological evidence suggests that cardiovascular risk is increased by noise exposure, resulting in individual lifetime risks that exceed cancer risk induced by air pollutants by far. The aim of this study is to determine the influence of traffic noise levels on population cardiovascular risk (ICD9: 410-414) and total mortality (attributable risk and life years lost). Estimation of population risk strongly depends on assumptions on dose-response relations and exposure prevalence. Therefore we varied assumptions on exposure duration necessary to elicit the effect, dose response relation and exposure prevalence as modified by selected aspects of sound propagation. Based on our present input and risk assessment model it is estimated that population attributable risk ranges between 2.6:1,000 and 6.7:1,000 and life expectancy is reduced by 9.5 - 25.2 days.
