“…Monte Carlo is the most widely used method for PRA. A number of articles indicate the increased use of Monte Carlo in risk assessment (Nayak and Kundu 2001;Linkov et al 2002;Kentel and Aral 2005;Mokhtari and Frey 2005). Therefore, in the second tier, the main tasks will incorporate Monte Carlo analysis into the exposure assessment and toxicity assessment to obtain a more detailed quantitative assessment.…”

Metals have been central to the development of human civilisation from the Bronze Age to modern times, although in the past, metal mining and smelting have been the cause of serious environmental pollution with the potential to harm human health. Despite problems from artisanal mining in some developing countries, modern mining to Western standards now uses the best available mining technology combined with environmental monitoring, mitigation and remediation measures to limit emissions to the environment. This paper develops risk screening and prioritisation methods previously used for contaminated land on military and civilian sites and engineering systems for the analysis and prioritisation of chemical risks from modern metal mining operations. It uses hierarchical holographic modelling and multi-criteria decision making to analyse and prioritise the risks from potentially hazardous inorganic chemical substances released by mining operations. A case study of an active platinum group metals mine in South Africa is used to demonstrate the potential of the method. This risk-based methodology for identifying, filtering and ranking mining-related environmental and human health risks can be used to identify exposure media of greatest concern to inform risk management. It also provides a practical decision-making tool for mine acquisition and helps to communicate risk to all members of mining operation teams.

“…Bayesian methods require elicitation of prior distributions for parameter values. Although these values are often criticized as subjective, they are also the best fitted for presenting uncertainty information in risk assessment (Nayak & Kundu, 2001). Moreover, non-Bayesian methods are also not entirely objective.…”

Site‐Specific Applications of Probabilistic Health Risk Assessment: Review of the Literature Since 2000

Risk Analysis

Whether and to what extent contaminated sites harm ecologic and human health are topics of considerable interest, but also considerable uncertainty. Several federal and state agencies have approved the use of some or many aspects of probabilistic risk assessment (PRA), but its site-specific application has often been limited to high-profile sites and large projects. Nonetheless, times are changing: newly developed software tools, and recent federal and state guidance documents formalizing PRA procedures, now make PRA a readily available method of analysis for even small-scale projects. This article presents and discusses a broad review of PRA literature published since 2000.
