The contribution of persistent organic pollutants to the environmental changes in Campania region, Italy: Results from the Campania Trasparente project

Abstract

Over the last two decades, the Campania region in Italy has been the focus of public debate and concern about environmental issues. Using data from soil, water, air, vegetables, animal products, and human blood, a multimedia monitoring study was performed to measure the contribution of persistent organic pollutants (POPs) to pollution in the region. We report results for a range of POPs in the air, including organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and phthalate esters (PAEs). Most of these chemicals are ubiquitous, with higher concentrations occurring in the urban and metropolitan territory of Naples. The residues of OCPs are attributed to their historical use; however, evidence of recent usage of technical Endosulfan exists in some areas. Although petrogenic sources are widespread, the pyrogenic source has dominated the release of PAHs. The Naples metropolitan area (NMA) serves as a regional emitter of POPs, and the long-term soil re-emission of some POPs does still exist. There are certain risks related to soil-borne PAHs, mainly in the urban (e.g., the Bagnoli brownfield site) and NMA, and more subordinately, in other provincial areas.
