The first phase of the program was devoted to evaluation of methods for measuring the content of nitrogen dioxide (D 1607-69), sulfur dioxide (D 2914-70T), dustfall (D 1739-70) total sulfation (D 2010-65), particulate matter (D 1704-61), and lead (D 3112) in the atmosphere(1-5).ASTM data series publication ;DS 55-S10.SmokeAirPollutionMeasurementSmoke.AirPollutionMeasurement.363.6Howes James E.1935-1380064Howes JPQKBBOOK9910161643803321Interlaboratory Cooperative Study of the Precision and Accuracy of the Determination of the Relative Density of Black Smoke3421025UNINA
