Finding F-1262

“Continuous measurements revealed average O3 production rates of 1040 ± 87 μg h−1 during the GUV222 operation in the offices, resulting in elevated O3 concentrations.”

Influence of Germicidal UV (222 nm) Lamps on Ozone, Ultrafine Particles, and Volatile Organic Compounds in Indoor Office Spaces (2024). Environ Sci Technol. Page 3. CKB 1130

Structure

Factor: Ozone (O₃)
Setting: office, DK
Study design: measurement study in office spaces in Denmark: germicidal ultraviolet lamps with a peak emission at 222 nanometres were run in the rooms while ozone, ultrafine particles and volatile organic compounds were measured continuously before, during and after operation, under unoccupied conditions and with one and with two people present, with the ozone production rate also measured against the ultraviolet path length (class 3)
Effect: emission-rate 1040
Caveat: the sentence prints the spread as a plus-minus value without naming it
