Air pollutants connected to emergency hospital admissions 
A study by the Chinese University of Hong Kong has found significant association between daily emergency hospital admissions and the levels of five air pollutants: sulphur dioxide, nitrogen oxides, ozone, PM10 and PM2.5. For every 10mg/m3 increase in these pollutants, rates of hospitalization for chronic obstructive pulmonary disease increased from 0.7% to 3.4%. Ozone had the strongest effect on admissions, whilst sulphur dioxide, nitrogen oxides and ozone had stronger effects on admissions during the cold season.
