Limerick's air quality is generally good by Irish standards, benefiting from Ireland's Atlantic exposure and the Shannon River estuary providing reliable ventilation across this mid-western Irish city. Vehicle traffic on the M7 and the surrounding pharmaceutical and technology manufacturing — including Analog Devices and other major operations — contribute local sources, while the Atlantic maritime climate's stormy weather provides effective natural atmospheric washing and Limerick's pharmaceutical corridor is the most distinctive industrial emission source throughout the year.
