Summary

some areas in the Campania region (southern Italy) have attracted media coverage in the past 15 years, and are considered a dramatic example of an extremely polluted area. The environmental pollution issue has become a significant concern in the Campania Region as a result of the "waste management crisis" that mainly affects the northern part of the region, encompassing 91 municipalities. As a consequence, in the last few decades, a large rural area between the provinces of Naples and Caserta, primarily used for agriculture and livestock breeding, was considered to be at high risk of contamination due to the illegal disposal of urban and industrial waste. In these landfills, a broad range of hazardous wastes from different parts of Italy has been found. In addition, the wastes have often been open-air burned, leading to this area being named the "Land of Fires". Senior and Mazza first highlighted the high incidence of cancer deaths in a specific area of the Campania region (compared to regional and national rates), which was identified by the authors as the "triangle of death". Afterwards, several studies reported a link between illegal waste disposal and an increased risk of cancer for the population, potentially associated with human exposure to carcinogenic substances such as dioxins, dioxin-like compounds, or polycyclic aromatic hydrocarbons, which can be released into air, soil, and water bodies through the illegal dumping and burning of waste. Within this study, 4,227 subjects were enrolled in the SPES trial, considering healthy subjects living in several regional areas with different environmental pressures. Blood dioxins and heavy metals were analyzed. Gut microbiome was analyzed on a subset of 359 subjects from the three different exposure area.

Conditions

  • Environmental-Pollution-Related Condition

Interventions

OTHER

Determination of dioxins (PCDD/Fs), polychlorinated biphenyls (PCBs) and trace elements

Peripheral blood (about 100 mL in several aliquots) was collected from the volunteers, in the early morning, in blood collection tubes (SST II Advance Tubes, BD Vacutainer). The samples were left for approximately 50 min, then the serum was separated from whole blood by centrifugation at 2,000 rcf for 10 min at 4 °C and then aliquots were stored at -80°C until analysis.
