Finding F-0112

“In contrast, coarser particles with diameters of 1.0–4.0 μm dominate the mass concentration, contributing 73.1% of the total mass.”

Structure

Source: Cooking
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Setting: laboratory, CN
Study design: laboratory measurement-method comparison: cooking fumes generated under simulated typical cooking conditions, manual gravimetric analysis as benchmark against an optical particle counter (Promo 3000), a photometer (DustTrak 8533) and infrared spectrophotometry (class 4)
Effect: other 73.1
Caveat: cooking fumes under simulated typical cooking conditions

A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
