Cork's air quality is generally good, benefiting from consistent Atlantic westerlies providing reliable maritime ventilation across this southern Irish port city. The Lee river valley and the surrounding Cork Harbour provide natural ventilation corridors, while vehicle traffic on the N22 and surrounding road network and the historically industrialised Ringaskiddy chemical and pharmaceutical complex in the outer harbour contribute local sources. Wood burning in suburban areas generates localised winter PM2.5 peaks across the valley.
