A basic study on personal exposure to nitrogen dioxide (NO2)

Personal exposure of children to nitrogen dioxide.

Combined exposure to ozone and nitrogen dioxide.

The combined effects of ozone and nitrogen dioxide were assessed in an in vitro test system utilizing human red cells. In general, these two pollutants had additive effects on the parameters measured which included osmotic fragility, acetylcholinesterase activity, lipid peroxidation, reduced glutathione and methemoglobin levels. However, at lower pollutant doses a synergistic increase in lipid ...

Personal exposure of Paris office workers to nitrogen dioxide and fine particles.

AIMS (1) To obtain an overall estimate of variability of personal exposure of Paris office workers to fine particles (PM(2.5)) and nitrogen dioxide (NO(2)), and to quantify their microenvironmental determinants. (2) To examine the role of potential determinants of indoor concentrations. METHODS Sixty two office workers in a Paris municipal administration (all non-smokers) were equipped with p...

Distribution and determinants of personal exposure to nitrogen dioxide in school children.

OBJECTIVES To assess the distribution of personal exposures to nitrogen dioxide (NO2) in school children, and to investigate factors that might influence personal exposure. METHODS NO2 exposures were assessed by use of passive diffusion tubes for 46 children aged 9-11 years, selected from two Southampton schools. The tubes were worn for seven days, and parallel measurements were made with sta...

Activity pattern and personal exposure to nitrogen dioxide in indoor and outdoor microenvironments.

People are exposed to air pollution from a range of indoor and outdoor sources. Concentrations of nitrogen dioxide (NO(2)), which is hazardous to health, can be significant in both types of environments. This paper reports on the measurement and analysis of indoor and outdoor NO(2) concentrations and their comparison with measured personal exposure in various microenvironments during winter and...
