Finding F-0154

“For PM1.0 emissions, the highest recorded value is for sieve analysis in the construction material laboratory (474.3 μg/m3), and the lowest value is for the preparation of the specimen on a dynamic triaxial compression test (83.3 μg/m3).”

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Population: instructors and civil engineering students
Setting: university laboratory, TR
Study design: measurement study of PM1.0, PM2.5, PM4.0 and PM10 during seven routine experiments in civil engineering laboratories of a university in Izmir, followed by mitigation measures for the three dustiest experiments (class 4)
Effect: other 474.3
Caveat: PM1.0 filed under particulate-matter, there is no finer slug
