The emission of airborne particulate matter is produced by the industrial processes of metal extraction from electronic waste (e-waste). These aerosols can transport organic contaminants, such as polyaromatic hydrocarbons and polybrominated biphenyls. These pollutants are proven to have long-term effects on workers' health. In this work, we characterize aerosol particles and dust de-
posited from a recycling process of printed circuit boards and waste cables in a recycling plant. A Scanning Mobili- ty Particles Counter and Sizer (SMPCS) was used to measure the size distributions of ultrafine particles. A Mi-
cro-Orifice Uniform Deposition Impactor (MOUDI) collected aerosol particle samples for chemical analysis. All plant compartments checked are subject to high particulate matter concentrations during work hours. Concentra-
tions of organic pollutants in the aerosols do not pose a short, or long-term health risk. However, the accumulation of aerosols in other compartments in the form of
dust may present an indirect danger to workers’ health.

Nowadays, urban landscapes are constantly evolving, influenced by diverse human needs and contexts, demanding innovative and efficient plan solutions. Non optimal space planning causes a substantial reduction of urban living quality of life, inclusion and mobility problems, relational complexity, low space resources access and use connected with eco-system services network break. “Design for all” approach represents an interesting plan tool able to match people connections’ needs to urban environmental quality improvement aims. This clue is supported by the experience of the first case study that considers universal design’s planning positive effects for resident people in the Italian city of Trieste. This is specially related to efficient and effective urban public space perception and services’ use for aged and disabled people. This operative approach also can be used to check out and assess the ecosystem services network part role. At the same way, the varying, and mixed structure of the city of Trieste becomes the necessary elements for re-think and plan the urban way of living with new functions using open space work tool, as highlighted in the second case study described in the paper.
