Abstract Sources and concentrations of indoor nitrogen dioxide (NO2) were examined in Barcelona, Spain, during 1996– 1999. A total of 340 dwellings of infants participating in a hospital-based cohort study were selected from different areas of the city. Passive filter badges were used for indoor NO2 measurement over 7–30 days. Dwelling inhabitants completed a questionnaire on housing characteristics and smoking habits. Data on outdoor NO2 concentrations were available for the entire period of… 
Concentrations and determinants of NO2 in homes of Ashford, UK and Barcelona and Menorca, Spain.
Principal determinants associated to indoor NO2 in three different sites of Europe: Ashford, Barcelona and Menorca (Spain) were the energy source present in the home and cigarette smoking, despite these areas presented different climates, levels of outdoor contamination, housing characteristics and ventilation behavior.
Activity pattern and personal exposure to nitrogen dioxide in indoor and outdoor microenvironments.
The measurement and analysis of indoor and outdoor NO(2) concentrations and their comparison with measured personal exposure in various microenvironments during winter and summer seasons and the estimated results were closely correlated, but showed some underestimation of the measured personal exposures to NO( 2) concentrations.
Relationship between indoor and outdoor NO2: A review
Abstract Studies have proved that outdoor nitrogen dioxide (NO2) has adverse health effects for people. Nowadays, most people spend much more time indoors than outdoors, and the indoor NO2
Emission of Nitrogen Dioxide from Butane Gas Heaters and Stoves Indoors
The ratios of the living room and kitchen NO2 values to their corresponding outdoor levels were found to be higher in winter than in spring and summer, which will have significant effects on estimating health risks related to the used of butane gas heaters in residential homes.
Estimation of outdoor NO(x), NO(2), and BTEX exposure in a cohort of pregnant women using land use regression modeling.
This is the first study using LUR to assess the intraurban variability of BTEX in Europe, with a model including altitude and source-proximity variables that explained 74% of the variance in BTEX levels.

It is suggested that VOCs exposure was associated with an elevated risk of childhood AL, and that more attention should be paid to indoor air pollution as a risk factor of Childhood AL.
Nitrogen dioxide and household fuel use in the Pakistan.
Overall fuel selection showed no significant effect on NO(2) levels, however the NO( 2) concentrations may pose a significant threat to the health of people, especially women and children.
A model for estimating the lifelong exposure to PM2.5 and NO2 and the application to population studies.
A methodology to simulate the lifelong exposure to PM2.5 and NO2 for individuals in Europe is developed by developing a probabilistic model that integrates an outdoor air quality model, a model estimating indoor air pollution, an exposure model, and a life course trajectory model for predicting retrospectively the employment status.
Sources of nitrogen dioxide (NO2) in New Zealand homes: findings from a community randomized controlled trial of heater substitutions.
It is found that homes that used unflued gas combustion appliances for heating and cooking had higher NO2 levels compared with homes where other fuels were used, and institutional incentives need to be increased to increase the use of more effective, less polluting fuels.
Indoor Air Pollution From Gas Cooking and Infant Neurodevelopment
This study suggests a small adverse effect of indoor air pollution from gas cookers on the mental development of young children.


Impact of residential nitrogen dioxide exposure on personal exposure: an international study.
Nitrogen dioxide (NO2) concentrations were measured during two-day winter periods in indoor and outdoor environments, and these concentrations were compared with simultaneously measured personal
Sources and concentrations of indoor nitrogen dioxide in Hamburg (west Germany) and Erfurt (east Germany).
The most important predictors of indoor NO2 concentrations were gas in cooking followed by other characteristics, such as ventilation or outdoor NO2 level, as well as the contribution of the most important indoor sources (e.g. the presence of gas cooking ranges, smoking) and outdoor sources (traffic exhaust emissions).
Personal exposure to nitrogen dioxide in the Los Angeles Basin.
A large scale study of human exposure to nitrogen dioxide (NO2) was conducted in the Los Angeles Basin, the only metropolitan area in the United States that exceeds the NO2 NAAQS. Data are available

Findings suggest that indoor NO2 concentrations are related to the atmospheric NO2 and type of heating appliances, and are also affected by automobile exhaust in homes located in roadside areas.
Factors affecting individual exposure to NO2 in Genoa (northern Italy).
The main household characteristics which were shown to affect personal NO2 exposure were the presence of a chimney equipped with an active aspiration device in the kitchen and the heating system.
Distribution and determinants of personal exposure to nitrogen dioxide in school children.
Findings reinforce the need for personal monitoring of exposure in studies investigating potential health effects of NO2 in children, and investigate factors that might influence personal exposure.
Respiratory effects associated with indoor nitrogen dioxide exposure in children.
Exposure to NO2 at hourly peak levels of the order of > or = 80 ppb, compared with background levels of 20 ppb was associated with a significant increase in sore throat, colds and absences from school, and significant dose-response relationships were demonstrated.
Exposure to nitrogen dioxide and the occurrence of bronchial obstruction in children below 2 years.
The results suggest that NO2 exposure at levels observed in this study has no detectable effect on the risk of developing bronchial obstruction in children below 2 years of age.
Health effects of daily indoor nitrogen dioxide exposure in people with asthma.
Daily personal exposures to NO2 are associated with asthmatic symptoms in children, and a significant interaction between NO2 and age 35-49 yrs was demonstrated, which indicates that indoor NO2 exposure, and respiratory symptoms in people with asthma was evaluated.
Domestic Nitrogen Oxide Exposure, Urinary Nitrate and Asthma Prevalence in Preschool Children
It is confirmed that there is a positive association between nitrogen dioxide exposure from gas appliances and the prevalence of respiratory symptoms, but urinary nitrate is not a useful biomarker of exposure at these levels.
