(Journal of Exposure Science & Environmental Epidemiology) A pilot study was conducted to understand the impact of nitrogen dioxide (NO2) exposure on pediatric asthma patients - with a small personal NO2 sensor to monitor exposure levels in the homes of the patients and their hospital records and self-reported symptoms were also collected. The study found that 17 of the patients had at least one hour each day with an average NO2 exposure greater than 21 ppb. The frequency of acute NO2 exposure was higher in the group that had gas stoves and showed a positive correlation with hospital admissions.
