Exposure to PM2.5 and cardiovascular diseases in Portugal – the contribute of PMCardImpact project

Abstract Particulate matter with a diameter of 2.5 μm or less (PM2.5) are one the air pollutants more detrimental to human health, being responsible for around 400 000 premature deaths in Europe every year. The cardiovascular diseases (CVD) and pollution linked, existing evidence causal relationship between exposure particulate morbidity mortality. Under scope PMCardImpact, national funded project, data collected from Portuguese monitoring platform (2005-2021) (>60 stations) was used estimate attributable number cases acute myocardial infarction. parameters such as exposure-response factors will support risk assessment AirQ+ software (WHO Regional Office Europe). Preliminary results showed that exceedances Air Quality Directive Portugal ranged 0.1 % 10.2% PM10 PM2.5 2019. Results obtained include CVD population. Four scenarios be considered presenting results: current scenario exposure, new WHO guidelines, European Commission lastly, worst-case scenario. This starting point calculation burden disease represent Portugal. With view promote science policy interface, PMCardImpact project make available makers needed supporting information act, including actionable knowledge on trends related health effects, implement reducing policies. work is by FCT/MCTES through funds (EXPL/SAU-PUB/0944/2021) CESAM (UIDP/50017/2020 + UIDB/50017/2020 LA/P/0094/2020).
