Two locations were investigated; the industrial Acheson process furnace hall and a pilot furnace hall; both of which represent an active operating furnace. The geometric mean of the particle number concentration in the Acheson process furnace hall was 7.7 104 particles/cm3 for the UFP fraction and 1.0 105 particles/cm3 for the submicrometre fraction.
