Differentiated health impacts of primary and secondary ultrafine particles

Objective

Exposure to particulate matter (PM) has been linked to negative health effects. Traditionally attributed to PM<10µm and<2.5µm, negative health effects may be enhanced with decreasing particle size, suggesting that ultrafine particles (UFP, PM<0.1µm) might be responsible for what has previously been attributed to larger size fractions of PM.
According to their origin, UFP can be primary (directly emitted to the atmosphere) or secondary (formed in the atmosphere from precursor gaseous pollutants). In central European cities, UFP particle concentrations (N) are mainly affected by road traffic emissions, as evidenced by the parallel variation of N and Black Carbon (BC, traffic tracer) concentrations. However, in European regions with high insolation, the maximum N is observed at midday (when BC is low) due to photochemical nucleation. A methodology developed by Rodriguez et al. (2007) allows the quantification of the primary (N1) and the secondary (N2) contribution to total N.
Depending on origin and size, UFP may differently affect human health but no study has yet tackled this key issue. Moreover, there are currently no legal ambient standards for UFP.
The main objectives of Health1UP2 (Differentiated health impacts of primary and secondary ultrafine particles) are (i) to uncover the differences in N1 and N2 in the cities of London (UK), Barcelona (Spain), Zurich (Switzerland) and Helsinki (Finland), based on long time-series of size-segregated UFP and BC data, and (ii) to determine the health impacts (mortality and hospital admissions as outcomes) of the exposure to differentiated N1 and N2 in different size-ranges in these cities.This research requires an international collaboration, since different meteorological conditions, pollutant emissions and other parameters influence divergently on N1 and N2. The results of this work will serve as indication to the corresponding authorities of which pollutants should be included in future EU legislation about air quality.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

MSCA-IF-EF-ST - Standard EF

Coordinator

KING'S COLLEGE LONDON
Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
