Sources of particle number concentration and noise near London Gatwick Airport.

ABSTRACT: There is increasing evidence of potential health impacts from both aircraft noise and aircraft-associated ultrafine particles (UFP). Measurements of noise and UFP are however scarce near airports and so their variability and relationship are not well understood. Particle number size distributions and noise levels were measured at two locations near Gatwick airport (UK) in 2018-19 with the aim to characterize particle number concentrations (PNC) and link PNC sources, especially UFP, with noise. Positive Matrix Factorization was used on particle number size distribution to identify these sources. Mean PNC (7500-12,000 p cm^-3) were similar to those measured close to a highly trafficked road in central London. Peak PNC (94,000 p cm^-3) were highest at the site closer to th
