Air pollution and meteorological conditions significantly contribute to the worsening of allergic conjunctivitis: a regional 20-city, 5-year study in Northeast China

C. Lu, J. Fu, et al.

This research by Cheng-Wei Lu and colleagues uncovers alarming trends in allergic conjunctivitis incidence linked to air pollution and weather conditions in Northeast China. With a notable 7.6% annual increase, the findings highlight critical thresholds for pollutants like SO2 and NO2, surpassing safety standards and raising environmental concerns.

Abstract

This study investigates the association between allergic conjunctivitis (AC), air pollution, and meteorological conditions in Northeast China (2014-2018). Results show a 7.6% annual increase in AC incidence, highest in provincial capitals. Incidence is positively correlated with PM2.5, PM10, CO, SO2, NO2, O3, air temperature, and wind speed, but negatively correlated with relative humidity. Threshold values for pollutants and meteorological factors were determined, some exceeding Chinese and WHO standards, highlighting environmental risks, particularly for SO2, NO2, and O3.
