This study examines the influence of urban parks on air quality and noise in the city of Tel-Aviv, Israel, by
investigation of an urban park, an urban square and a street canyon. Simultaneous monitoring of several
air pollutants and noise levels were conducted. The results showed that urban parks can reduce NOx, CO
and PM10 and increase O3 concentrations and that park's mitigation effect is greater at higher NOx and
PM10 levels. During extreme events, mean values of 413ppb NOx and 80 mG/m3 PM10 were measured in
the street while mean values of 89ppb NOx and 24 mG/m3 PM10 were measured in the park. Whereas
summer highest O3 values of 84ppb were measured in the street, 94ppb were measured in the park. The
benefit of the urban park in reducing NOx and PM10 concentrations is more significant than the disadvantage
of increased O3 levels. Furthermore, urban parks can reduce noise by ~5 dB(A)
