Research Program Area: Health & Exposure
This is the first interim report on the results of project 96-312, "Development of a Short Averaging Time Indoor Nitrogen Dioxide Monitor", conducted by Battelle for the California Air Resources Board (CARB). This report presents the procedures and results of laboratory testing of three electrochemical sensor-based monitors for nitrogen dioxide (NO2) and nitrous acid (HONO). Specifically, this report covers the laboratory testing that was done up to the point at which the monitors were subjected to preliminary field testing. The results of the preliminary field tests, and of additional laboratory tests, will be the subject of a second report.
This report was made necessary by a change in the schedule for this project. Originally, it was planned that nearly all the laboratory testing would be completed before the preliminary field testing was conducted. However, preliminary field testing was conducted earlier than planned, in order to coordinate with an ongoing project in a research house in Chicago. As a result, laboratory testing was interrupted, and was completed after the field testing. This report documents the laboratory testing that justified the readiness of the monitors for the preliminary field trial.
