Reducing risks from Occupational exposure to Coal Dust (ROCD) EU Research Fund for Coal and Steel (RFCS) project #754205 Despite international efforts to limit worker exposure, coal mine dusts continue to impact the health of thousands of miners across Europe. Modern, practicable assessment tools and devices are urgently needed to improve risk models, control dusts and protect workers, particularly from the fine fraction (PM2.5) which is increasingly implicated in human disease. These issues will be addressed through 5 integrated work packages (WPs) by a world-leading interdisciplinary consortium of 10 institutions from UK, Poland, Slovenia, Germany and Spain. Global dissemination of developed protocols and training modules, and improved monitoring and suppression devices will reduce incidences of coal mining-related disease…

The HOUSE project aims at investigating the atmospheric scenarios and processes yielding to the high formation rates of ozone (O3), ultrafine particles (UFP) and secondary aerosols (SA) typical of the Western Mediterranean Basin in summer. In this area the formation of high levels of these atmospheric constituents take place in a very complex system in which solar radiation, humidity, temperature, volatile organic compounds, inorganic gaseous pollutants, halogens, radicals, ozone and ultrafine particles play a major role. The analysis of these processes is important for policies focusing on abatement of both climate forcing and health-ecosystems effects of air pollution. The HOUSE project will provide important information for designing and assessing air quality and climate plans for abating photochemical pollutants in Spain. Within the HOUSE project the optical characterization of tropospheric aerosols will consist of both ground and columnar measurements performed at the Montseny and Montsec GAW/ACTRIS stations. The obtained extensive and intensive aerosol optical measurements will be related with the physical and chemical measurements of aerosols in order to derive site-specific aerosol optical parameters considered as fundamental inputs for climate models and policies.
COST Action CA16109 Chemical On-Line cOmpoSition and Source Apportionment of fine aerosoL, COLOSSAL focuses on fine atmospheric aerosols. It is well known that exposure to aerosols exerts a negative impact on human health and that aerosols affect climate and the environment. These effects are dependent on the composition and sources of these fine atmospheric aerosols (particulate matter with aerodynamic diameter below 2.5 µm, PM2.5). The main challenge of the Action is to consistently assess their spatial variability (across Europe), their temporal variability (at a one hour time resolution or better), their seasonality (using long term datasets), their phenomenology (chemical composition) and their sources. To this end many research groups and some air quality monitoring networks in Europe and across the world have acquired recently-developed chemical composition measurement instrumentation. These include the Aerosol Chemical Speciation Monitor (ACSM) (based on Aerosol Mass Spectrometer (AMS) technology), which measures non-refractory ammonium, nitrate, sulfate, chloride, and organic mass, and instruments that measure the refractory black carbon, such as the Aethalometer and Multi Angle Absorption Photometer (MAAP). These new high time resolution techniques, which chemically characterize the aerosols, are capable of operating for long time periods and have only been available in 5-10 years. The processing and interpretation of the data from these instruments has matured to a stage where harmonized across Europe is now possible; this will be achieved by a network built through the present Action to jointly develop the capacity for the interpretation of the measurements gathered using these techniques. The outcomes of the Action will be relevant for air quality modellers and policy makers.

Aerosol optical properties are strongly dependent on ambient relative humidity. Depending on their size, composition and the ambient humidity, atmospheric particles will take up varying amounts of water, thereby altering their optical properties and impacting their contribution to aerosol radiative forcing. Along with particle size, this humidity dependence also plays an important role in the life cycle of atmospheric particles including their growth into cloud droplets and wet deposition processes removing them from the atmosphere. Global models use a variety of schemes for implementing hygroscopic growth. The representation of hygroscopic growth in models may result in predicted aerosol optical properties being quite different from observations. To date the ability of global models to predict hygroscopic growth has not been rigorously evaluated against in-situ measurements due in part to the lack of harmonized and globally available hygroscopicity data.

Prediction of emissions and exposure to micro- and nanoparticles in industrial environments Major knowledge gaps remain regarding exposure to fine and ultrafine particles in indoor air. Industrial environments are a special case study, given the broad range of sources and processes with potential to generate particle emissions and therefore exposure to these contaminants. However, to date, studies on air quality in this kind of environments are relatively scarce in the scientific literature. Unlike direct emissions, fugitive particulate emissions in industrial environments lack legal guidelines (e.g., limit values), and this is mainly because of the absence of a sound scientific basis on which the mechanisms and processes by which they are generated are described. Therefore, these indoor emissions have a large potential for improvement to reduce impacts on air quality, health, and possibly climate. The overall objective of the PREDEXPIN project is to assess the impact of industrial activities on air quality and exposure to micro- (PM) and nanoparticles (NP) in indoor air. To this end, the mechanisms controlling particle release to workplace air in industrial environments and their impact on personal exposure are being evaluated in a number of selected indoor industrial processes under real-world operating conditions at pilot plant-scale. IThe processes selected are both traditional and innovative, being mechanical in nature (e.g., handling of nanoparticles, milling/grinding activities) and thermal (e.g., plasma projection). The potential impact of these emissions of on outdoor air emissions is also assessed. In parallel to these activities, dustiness tests are being carried out to determine PM and NP emissions from selected raw materials, using a highly innovative approach based on the development of a novel modular tool. The ultimate goal of the project is to improve indoor air quality in industrial environments by achieving a better understanding of the release mechanisms of particles in indoor air, which will in turn allow for the design and implementation of adequate and tailored mitigation strategies. The project will have a major impact on four main areas: (a) the assessment of the levels of exposure to micro- and nano-scaled particulates in industrial environments; (b) increased understanding of the release mechanisms and processes of particles in indoor and outdoor air from industrial activities; (c) mitigation of the impacts of these emissions on indoor air quality and on worker exposure, by developing effective mitigation strategies; (d) the optimisation of industrial processes by increasing their efficiency through the reduction of fugitive emissions.

Safe production and Use of Nanomaterials in the Ceramic Industry CERASAFE aims to assess and improve environmental health and safety (EHS) in the ceramic industry. The project's objective is to study industrial processes and activities, which may generate nanoparticle emissions into workplace air, and to assess worker exposure by evaluating the particle release processes, characterizing the particles emitted, and understanding their toxicity. Finally, mitigation measures to minimize exposure will be proposed. CERASAFE will also develop a tool to discriminate engineered nanoceramic particles from background aerosols, thus innovating in the field of characterisation methods relevant for EHS. The project will establish a set of Good Manufacturing and Use Practices for nanoceramic materials. Results will be collected in a public database complemented with risk assessment and including recommendations for industry, users and stakeholders to ensure the safe production process for nanoceramic materials.

New technical improvements in monitoring equipment are producing increasingly sophisticated instruments that are becoming more portable, making it practical for an individual to monitor a range of different air quality parameters (PM sizes and number, various gases) simultaneously while moving through the city. This opens up the possibility of recording much more accurately the actual real-time dose of air pollutants inhaled daily by regular commuters. Our starting hypothesis is that the quality of the air we breathe while commuting by public bus will vary greatly according on the type of fuel and post treatment (e.g. SCRT filters) technology, route chosen, location inside the bus and infiltration of outdoor air, the latter mostly related to the age of the bus and seasonal variations influencing ventilation and air conditioning operating conditions. The primary objective of this project is to significantly improve our understanding of what controls air quality inside public buses, identifying the effect of each variable to allow us to elaborate a protocol of best practice regarding air quality while commuting in this transport mode.

The overall aim of IMPROVE (Implementing Methodologies and Practices to Reduce air pollution Of the subway enVironmEnt) is to provide a benchmark study that will lead to real improvement in subway air quality. Published research has shown that in some cases air quality in subway stations and access tunnels can be poor, although the amount of information available remains rather limited and piecemeal in character. Physical measurements frequently consider only one aerosol size fraction, sampling campaigns may be limited in time and place, and chemical analyses are usually partial and/or small in number. IMPROVE LIFE is bringing together all information published in different cities across the world over the last 20 years, identify the main pollution sources, and ascertain just where we are in our understanding of the subject. The understanding and conclusions reached from this initial state-of-the-art overview of the problem will then be applied to the underground rail system in Barcelona.

Optical properties and radiative forcing of atmospheric aerosols in the Western Mediterranean depending on aerosol sources and chemical composition. The PRISMA project (MEC , CGL2012-39623-C02-01) has as major objective to assess the direct radiative forcing caused by the tropospheric aerosols in the Western Mediterranean Basin (WMB). With the PRISMA project the first database on physical, chemical and optical properties of tropospheric aerosols in the WMB was obtained through in-situ surface measurements performed at remote mountain top stations (> 1500 m) with no local anthropogenic emissions influence. Moreover, ceilometers data and information from instrumented flights allowed the detailed physic-chemical characterization of different aerosol layers which typically form in the area through regional recirculation processes. Thanks to the PRISMA project the sources of aerosols with major impact on the climate of the WMB were determined and characterized thus allowing the study of the relationship between Air Quality and Climate.
