[A passive sampler for nitrogen dioxide].
Passive samplers run without electric power supply, are easy to handle and thus are suitable for exposure measurements in epidemiological studies, to evaluate indoor air quality, to control ambient concentrations etc. Passive sampler values agree with continuous measuring apparatus within 85 to 105% and the lower detection limit is 4 micrograms/m3 for a one week exposure or longer.
