In 2018, Arias proposed a citizen science methodology to monitor odor pollution,[17]​ which was validated within the framework of the D-NOSES project in 10 case studies in Europe, Chile and Uganda. Barcelona was the pioneer pilot. More than 600 observations of the smell of waste and wastewater were collected with the participation of more than 80 residents in the Forum area and their plausibility was evaluated.[18]​ Furthermore, the D-NOSES project had the additional objective of introducing odor pollution into public agendas, as it is a poorly or unregulated topic in most European countries, being the second cause of environmental complaints after noise. A multi-level governance model was created[19]​ and documents were produced to inform public policy, including a public policy report,[20]​ the Green Paper on Odor Pollution and the Strategic Roadmap for Odor Pollution Governance.[21]​ The results were presented at an event in the European Parliament, Revisiting odor pollution in Europe, to call for the recognition of environmental odors as a pollutant and to call for a common European regulatory framework. As a result of the importance of controlling odor pollution through citizen science, it was introduced in an amendment proposed by the European Committee of the Regions (CoR) to the Green Deal Zero Pollution Action Plan. The amendment was approved unanimously on January 27, 2022,[22]​ which establishes the basis for the adoption of citizen science methodologies to control odor pollution at the European level.

At the national level, we opted for the creation of a working group for the standardization of the methodology developed in D-NOSES at a technical level in 2019, promoted by the AMIGO association, partners of D-NOSES. A group of more than 15 experts was formed, including odor pollution consultants, experts in citizen science, emission activities, environmental authorities and citizen representatives who prepared the technical document. In 2023 and with the collaboration of the UNE, the draft standard PNE 77270 “Construction of collaborative odor maps through citizen science” has been published,[23]​ which will allow the adoption of the new methodology officially by environmental authorities or emitting activities and will promote future regulations to protect affected communities. In addition, it is the first technical standard with the name “citizen science” in the title, which will contribute to the recognition of the practice and increase confidence in the validity of the data generated by citizens.

With the creation of the free OdourCollect app, he wins, in La Coruña, the Prismas Casa de las Ciencias Award for Dissemination, in the category of best singular project in 2021.[3][2]​.

Also in 2021, it received the subsidy granted to technology-based companies led by women, from the Generalitat of Catalonia. An initiative that is part of the DonaTIC Plan that promotes the empowerment of women and female leadership in the information technology sector in Catalonia.[3]​.

In May 2022 she received the eWoman Igualdad award, awarded by El Periódico "El Periódico (Barcelona)") and Prensa Ibérica.[11]​ And in June she won for her professional career the second edition of the CaixaBank Self-Employed Professional Woman Award, in the Territorial Directorate of Barcelona, an award that recognizes the business excellence of self-employed professionals throughout Spain, both in terms of the success of their current business activity and the general trajectory of his career.[3][24]​.
