Abstract
Health risk assessment is a vastly applied subject in the field of environmental management. It can be described as a process to estimate the nature and probability of adverse health effects of the receptors. There are four main steps in health risk assessment: hazard identification, dose response assessment, exposure assessment and risk characterization,
Fine particulate matter (PM2.5) is a widely studied air pollutant in environmental research. There are many studies that pointed out the association between PM2.5 exposure and several health endpoints, including a variety of respiratory diseases, cardiovascular diseases, and even to cause death. The WHO has classified it as Group 1 carcinogen. The United Steates is the first country to establish the regulatory standards for PM2.5.
PM2.5 is an air pollutant which is in particulate form, its chemical speciation is quite complicated, consists of elemental carbon, organic carbon, sulfate, nitrate, ammonium, heavy metals, PAHs and else. Differs from simple chemical hazards, its complicated characteristic makes it harder to evaluate the risk of PM2.5. To date, there are several different risk assessment methods of this pollutant, and there is a need to put all these approaches in discussion in order to make a better understanding, to achieve the discrepancies among them, and finally to establish conclusions and recommendations as the feedback to regulatory considerations.
In this study, all available risk assessment methods of PM2.5 were collected and discussed. The details of these approaches and the discrepancies among them were provided. Furthermore, a risk assessment study of the chemical species of PM2.5 was performed. Finally, several conclusions and recommendations were given in order to provide some insight for decision makers.
