Abstract
Objectives: to estimate the contribution of locally-grown food consumption to perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) human exposure.
Design: residents of a PFAS-contaminated community of the Veneto Region (North-Eastern Italy) were categorized into two exposure groups, which refer to the period after the determination of serum levels of PFOA and PFOS conducted at baseline: 1. people drinking water filtered with double granular activated carbon (GAC) and not consuming locally-grown foods at all (reference group); 2. people drinking the same filtered water and which continue to consume only locally-grown foods. For each group, PFOA and PFOS daily intake rates (IR, ng/kg-day) were derived from measured PFOA and PFOS concentrations in treated water and local vegetable and animal food matrices. Then a one-compartment pharmacokinetic model was applied to predict PFOA and PFOS serum concentrations over time and the time needed to fall below a clinically significant threshold level of PFOA and PFOS (e.g., 20 ng/mL).
Setting and participants: the study area included 21 municipalities and 3 provinces (Vicenza, Verona, and Padua) located in the Veneto plain. Approximately 127,000 people lived in the most PFAS-contaminated areas on 31.12.2016; those aged 9 to 65 years were invited to participate in the Health Surveillance Plan (HPS), including laboratory tests and medical examination.
Main outcomes measures: predicted PFOA and PFOS serum levels (ng/mL) among residents in the contaminated area.
Results: compared to the reference group, residents who continued to consume locally-grown foods had an approximately 24% higher IR of PFOA and PFOS and this resulted in 3 more years for their PFOA and PFOS concentrations to fall below the threshold level of 20 ng/mL.
Conclusions: this study showed that the contribution of locally-grown food consumption cannot be ignored for people living in PFAS-contaminated areas.
期刊介绍：
Epidemiologia & Prevenzione, oggi organo della Associazione italiana di epidemiologia, raccoglie buona parte delle migliori e originali esperienze italiane di ricerca epidemiologica e di studio degli interventi per la prevenzione e la sanità pubblica.
La rivista – indicizzata su Medline e dotata di Impact Factor – è un canale importante anche per la segnalazione al pubblico internazionale di contributi che altrimenti circolerebbero soltanto in Italia.
E&P in questi decenni ha svolto una funzione di riferimento per la sanità pubblica ma anche per i cittadini e le loro diverse forme di aggregazione. Il principio che l’ha ispirata era, e rimane, che l’epidemiologia ha senso se è funzionale alla prevenzione e alla sanità pubblica e che la prevenzione ha ben poche possibilità di realizzarsi se non si fonda su valide basi scientifiche e se non c’è la partecipazione di tutti i soggetti interessati.
Modalità di comunicazione aggiornate, metodologia statistica ed epidemiologica rigorosa, validità degli studi e solidità delle interpretazioni dei risultati sono la solida matrice su cui E&P è costruita. A questa si accompagna una forte responsabilità etica verso la salute pubblica, che oggi ha ampliato in forma irreversibile il suo orizzonte, e include in forma sempre più consapevole non solo gli esseri umani, ma l’intero pianeta e le modificazioni che l’uomo apporta all’universo in cui vive.
L’ambizione è che l’offerta di nuovi strumenti di comunicazione, informazione e formazione, soprattutto attraverso l''uso di internet, renda la rivista non solo un tradizionale veicolo di contenuti e analisi scientifiche, ma anche un potente strumento a disposizione di una comunità di interessi e di valori che ha a cuore la salute pubblica.
