Excess charges of indoor air high quality to the health safety standards by uncontrolled public services. The average stage of formaldehyde in each facility ranged from 23.four μg/m3 to 141 μg/m3. The highest common worth of formaldehyde was in performance halls (141 μg/m3), with ranges in exhibition halls (112 μg/m3) and pubs (84.5 μg/m3) slightly decrease.

When calculating the HQ of non-cancer pollutants, the reference focus (RfC, mg/m3) ought to be transformed to reference dose (mg/kg/day) to reflect human exposure items. RfC is calculated based mostly on a median adult in the united states; therefore, RfC was converted based on common physique weight (70 kg) and every 하이퍼블릭 가격 day inhalation rate (20m3/day) for the us (US EPA, 1987). Smoking did not significantly improve the IAQ because solely 30% of the services allow smoking inside. Therefore the risk assessments did not bear in mind whether or not or not a facility allowed smoking indoors.
