Human Exposure to Dioxins and Other Contaminants Following an Accidental Fire at the Fiumicino Airport (Italy): A Public Health Response

In May 2015, a fire occurred at Terminal 3 of the Rome–Fiumicino International Airport. To respond to the health concern associated with the resulting emissions of combustion products, Pier D of Terminal 3 underwent a pre-emptive sequestration. The Italian National Institute of Health was asked to carry out environmental monitoring of the affected areas, and to evaluate the related risk for health. Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) were measured in air samples in the pre- and post-remediation phases. Results showed a decrease of 44% of the cumulative concentrations at Pier D after the remediation operations compared to those detected before. The human exposure assessment carried out after the remediation operations confirmed that there were no risks for people in the Terminal which was then reopened. Due to the lack of quality limit values or Italian national guidelines for indoor air, WHO air quality guidelines or legislative/guidance documents of other European countries were considered for the air quality assessment.
