Disparities in air pollution exposure among primary schools in Auckland: a geo-spatial analysis

Outdoor air pollution poses a significant threat to children, especially those in low socioeconomic areas exposed to dense traffic pollutants. This study explores the relationship between socioeconomic status (SES), ethnicity, and air pollution exposure among primary school children in Auckland, New Zealand. Findings indicate that NO₂ levels do not vary significantly between schools in low versus high SES areas; however, Pacifica children experience the highest exposure, with levels reaching up to 13.37 μg/m³. Central regions of Auckland show particularly high pollution levels, measuring 15.7 μg/m³-significantly above the regional average of 13.16 μg/m³, which amplifies health risks for children in these areas. These findings underscore the critical need for targeted interventions to mitigate the adverse effects of air pollution. Future research should broaden the scope to include more pollutants and utilize more recent data to assess the health impacts of air pollution. .
