Monitoring coastal pollution by using an integrated low-cost device

<p>Coasts are extremely sensitive areas and are internationally considered “hotspot” of environmental contamination. The presence of multiple human activities in these areas frequently lead to the potential increase in organic and inorganic pollutants. In particular, industrial and maritime activities, tourism, recreational activities, aquaculture and fishing contribute to the pollutants release in the coastal environments. In this context, northern Latium coastal area (northern Thyrrenian Sea, Italy) hosts several industrial activities of national and international relevance, located in a very restricted seaside area: the Port of Civitavecchia, one of the most important hub for cruise and commercial traffic in the Mediterranean Sea, the Torrevaldaliga Nord coal-fired power plant of the national energy company (ENEL), and the Tirreno Power combined cycle (gas-fueled) power plant. All these activities strongly contribute to the increase of pollutant load to the land as well as marine coastal environment. For this reason, a research project aimed at understanding the main source for the pollution has been undertaken in the last years. The project is particularly aimed at designing and testing of reliable low-cost devices (Gozzi et al., 2015, 2017) able to provide both the amount and typology of solid particles spread in the environment.</p><p>As a first step, the air quality inside the Civitavecchia harbor has been monitored for six months by measuring the content of PM1, PM2.5, and PM10 simultaneously to environmental parameters such as air temperature and humidity. The sensing station (Della Ventura et al., 2017) was equipped with a filtering set-up able to collect the solid load in the atmosphere with dimension > 400 nm. The filters were periodically removed from the station and studied by combining microscopic (optical and electron), spectroscopic (IR, Raman) and microchemical (SEM-EDS) techniques for a full characterization of microparticles typologies. Collected information, augmented by environmental (wind, rain) data from local broadcasting stations provides a valuable tool for assessing the contribution of anthropic (industrial and maritime) activities to the pollution in this coastal area.</p><p> </p><p>References</p><p>Gozzi, F., Della Ventura, G., Marcelli, A.
