The "Campania Trasparente" multiscale and multimedia monitoring project: an unprecedented experience in Italy.

<p>In 2015, the "Campania Trasparente" project (http://www.campaniatrasparente.it), a monitoring plan focused on assessing the environmental conditions of the territory of the Campania region, started thanks to the financial support of the regional government. The project's general management was in charge of the Experimental Zooprophylactic Institute of Southern Italy (IZSM).<br>In the project framework, the collection and analysis of many environmental and biological samples (including soil and air and human blood specimen) were completed. The primary aim of the whole project was to explore the existence of a link between the presence of some illnesses in the local population and the status of the environment and generate a reliable database to assess local foodstuff healthiness.<br>Six research units were active in the framework of the project. As for soil and air, the Environmental Geochemistry Working Group (EGWG) at the Department of Earth, Environment and Resources Sciences, University of Naples Federico II, was in charge of most of the research activities. Specifically, the EGWG completed the elaboration of the data on potentially toxic metals/metalloids (PTMs) and organic contaminants (PAHs, OCPs, Dioxins) in the regional soils and air.<br>The monitoring of air contaminants lasted more than one year, and it was completed employing passive air samplers (PAS) and deposimeters spread across the whole region.<br>Three volumes were published, including statistical elaborations and geochemical maps of all the contaminants analysed to provide both the regional government and local scientific and professional community with a reliable tool to approach local environmental problems starting from a sound base of knowledge.<br>Geochemical distribution patterns of potentially toxic elements (PTEs), for example, were used to establish local geochemical background/baseline intervals for those metals (naturally enriched in regional soils) found to systematically overcome the national environmental guidelines (set by the Legislative Decree 152/2006).<br>Data from the air, analysed in terms of concentration and time variation, were, instead, fundamental to discriminate the areas of the regional territory characterised by heavy contamination associated with the emission of organic compounds from anthropic sources.</p><p>The integration of all the data generated within the "Campania Trasparente" framework, including the data proceeding from the Susceptible Population Exposure Study (SPES), focusing on human biomonitoring (based on blood), allowed the development of a regional-wide conceptual model to be used as a base to generate highly specialised risk assessments for regional population and local communities affected by specific environmental problems.<br><br></p>
