Residents in the Villaggio Brollo area, affecting the municipalities of Ceriano Laghetto and Solaro, have reported unpleasant odors in recent weeks. Arpa Lombardia has responded to these reports by scheduling field inspections and planning to activate the ‘Tavolo Tecnico MOLF’ to identify the source of the olfactory nuisances. While Arpa monitors environmental aspects, the agency clarified that health-related matters fall under the jurisdiction of ATS. Arpa noted that no emergency situation has been reported, but they will act if danger is identified. In Ceriano Laghetto, authorities have identified an industrial source for the odors. The municipal administration, working with Local Police and Arpa Lombardia, has initiated a verification process to monitor emissions. Residents are being asked to provide detailed reports including location, time, duration, and intensity to help correlate data with meteorological conditions and local production activities. Reports of unpleasant odors have since expanded across the Brianza region, with complaints extending to the municipality of Cogliate. Local authorities in Cogliate suggest the odors likely originate outside their municipal borders, limiting their direct intervention capabilities.
