ONE-BLUE will provide an integrated assessment of contaminants of emerging concern (CECs) and their impacts, will develop new monitoring tools, and will provide an advanced understanding of the combined effects of CECs and climate change (CC) on the different marine ecosystems and their biodiversity. The following objectives are defined: • Improve the current knowledge of the concentrations, profiles, fate, behaviour, and effects of CECs, in the different marine compartments and ecosystems through three case studies (Atlantic and Arctic oceans and the Mediterranean Sea) and develop safety guidelines and protocols for future CECs monitoring in marine ecosystems. • Provide an advanced understanding of possible interaction between CC and CECs in marine ecosystems with studies under controlled conditions in marine mesocosms. • Develop a database (DB), the CECsMarineDB, following FAIR principles, with a database management system (DBMS) to collect the data generated in ONE-BLUE and capitalize data from other projects and existing DBs. A graphical user interface (GUI) will be developed and used for data exploration and demonstration of the fate and behaviour of CECs in a changing environment. • Provide new solutions in support of the implementation of relevant EU policies; (i) a series of new approach methodologies (NAMs) to improve the ecotoxicity assessment of CECs in marine ecosystems; (ii) a tiered effect-directed approaches (EDA) combining toxicological assessment and chemical analysis; (iii) an advanced ultrasonic system for sampling and enrichment micro/nanoplastics from seawater; (iv) a remote autonomous sensor to assess CECs in marine waters in quasi-real-time; a decision support system (DSS) based on machine and deep learning strategies to assess and forecast combined effects of CC and CECs in marine ecosystems. • Disseminate the project results and establish the exploitation plan for the developed technologies.

NEMO aims to create a turn-key solution through which new systems are integrated into existing infrastructure to empirically measure emissions and noise emitted by individual vehicles. The new measurement systems, together with the implementation of new mitigation solutions, form a global and scalable solution to improve air quality and reduce noise impact in EU cities. By the envisaged standardization, the systems will represent an instrument for enforcement against high-emitters in Low-Emission Zones and other sensitive areas. The first dimension comprises a new and enhanced autonomous remote sensing system that identifies noisy and polluting vehicles in existing traffic and make this information available to tolling or access systems. The system can be fully integrated into the road/rail infrastructure and will have the tools available to communicate with the existing data structure of both vehicle/train operators and road/rail authorities. The second dimension develops a holistic solution to mitigate noise and emissions of passing vehicles. This integral approach involves road texture optimization, green barriers, photocatalytic materials and microplastics collection in the asphalt layer pore network. The combined effect of dimensions 1 and 2 will achieve the targeted 30% improvement in air quality for road traffic and will exceed the targeted 20% improvement in noise. For rail traffic, NEMO will enable the acoustic determination and identification of individual wagons in passing trains. This improves the effectivity of tolling or banning policies for noisy cast iron block braked wagons. The NEMO consortium covers all the relevant technologies at already quite high readiness level and incorporates extensive experiences in the application and interpretation of vehicles’ noise and emission monitoring. The performance of the developed systems will be demonstrated, analysed and disseminated in four pilots (two for road, one for rail and one for shipping).
