Citizen scientists chart encouraging results for air pollution in Cork city 

Experiment saw 700 volunteers around the city install sensors around their homes in order to gauge NO2 levels, which can cause irreversible damage to the respiratory system

Levels of pollution from traffic are unsurprisingly heaviest around Cork’s city centre and its main entrances, a novel citizen scientist project has found.

The South Link and Commons Road were joined by MacCurtain Street, Lower Road, Leitrim Street, and Carroll’s Quay in presenting the highest levels of the pollutant nitrogen dioxide (NO2) from 700 sensors dotted around the city and suburbs.
