There is growing evidence that asthma symptoms can be aggravated or events triggered by
exposure to indoor nitrogen dioxide (NO2) emitted from unflued gas heating. The impact of …

Household gas appliances produce nitrogen dioxide (NO2), which may be associated with
an increase in symptoms in asthmatics. The relationship between indoor NO2 exposure, and …

Rationale: Chronic exposure to indoor nitrogen dioxide (NO2) is a public health concern.
Over half of US households have a source of NO2, and experimental data suggest potential …

BACKGROUND: Nitrogen dioxide (NO2) and environmental tobacco smoke (ETS) have
been associated with adverse respiratory effects. OBJECTIVE: We sought to assess the …

Background: It has long been assumed that the development of childhood asthma is related
to exposure to environmental chemicals, but it has thus far not been possible to …

Background Ambient and home exposure to nitrogen dioxide (NO 2) causes asthma
symptoms and decreased lung function in children with asthma. Little is known about the …

Background The effect of indoor nitrogen dioxide concentrations on asthma morbidity
among inner-city preschool children is uncertain. Objectives Our goal was to estimate the …

Abstract Background Nitrogen dioxide (NO2), an oxidant gas that contaminates both outdoor
and indoor air, is considered to be a potential risk factor for asthma. We investigated …

Background: Adverse respiratory effects in children with asthma are associated with
exposures to nitrogen dioxide (NO 2). Levels indoors can be much higher than outdoors …

Nitrogen dioxide is known as a deep lung irritant. The aim of this study was to find out
whether the relatively low ambient air NO2 concentrations in the northern city of Helsinki had …
