“…Ventilation and the amount of air pollutant sources are the two main factors that influence IAQ in the laboratory [8]. The pollutants that are emitted from the outside of the buildings, has the potential to be taken in by the ventilation system [9].…”

Laboratories are special micro-environments in university buildings in which the levels of pollutants depend on the nature of the experiments and the number of people employed. The aim of this study is to compare the airborne particulate (PM2.5) and the physical parameters in the existing indoor environment of Faculty of Forestry and Environment (FHAS) dry and wet laboratories. PM2.5, air temperature (AT), relative humidity (RH) and air speed (AS) were monitored for nine working hours in selected dry and wet laboratories. Dusttrak aerosol monitor and Kestrel 4500 were used to collect the data for PM2.5 and the physical parameters, respectively. Descriptive analysis was performed to summarize the data characteristics. Meanwhile, independent t-test and Pearson’s correlation were conducted to compare the mean variables for dry and wet laboratories and measure the linear association strength between parameters, respectively. The results showed that airborne particulates and RH recorded were below and within the Department of Occupational Safety & Health (DOSH) acceptable limits which is 150μg/m3 and between 40-70%, respectively. Some of the laboratories have AT in the range of 23-26°C while others were not in the acceptable range where Chemical Laboratory recorded the highest (30 ± 0.5°C), while Xylarium was the lowest (18 ± 2.2°C). As for the AS, majority of the laboratories did not have air movement in the range of 0.15 – 0.50 m/s. Some of them recorded no air flow for the entire monitoring hours. Independent t-test analysis showed there was no significant difference between dry and wet laboratories in terms of the airborne particles, AT and RH, except for AS (p<0.05). The results from Pearson’s correlation found that airborne particles have significant relationship with all physical parameters in wet laboratories, while only RH and AS were found significant in dry laboratories. Therefore, it can be concluded that both laboratories have similar indoor air quality except for AS which highly depends on the ventilation systems and occupants’ activities.

The indoor air quality (IAQ) of eleven naturally ventilated training laboratories was analysed to evaluate the health risk to occupants. IAQ evaluation included analysis of physical (temperature (T) and relative humidity (RH)), chemical (CO2, CO, O3, total volatile organic compounds (TVOC), and particulate matter (PM)) and microbiological (fungi and bacteria) pollutants. Monitoring was carried out in labs used for teaching different academic disciplines (biology, chemical, ecology, and computers) during two periods of the academic year. Ventilation rates (VR), air change per hour (ACH) in every lab, and the hazard quotients for each of the chemical pollutants and the accumulated (HQ and HI) were calculated. Environmental comfort was not fully satisfactory considering the RH and CO2 values, especially during hours with higher occupancy. Coarse particles and bacteria were generated indoor related to human activity. At chemical and biological laboratories, TVOC concentrations were sometimes above the recommended value, and all the labs presented VR below the European guideline’s recommendations. Results from this study show natural ventilation is not enough to get an adequate IAQ, although no significant non-carcinogenic risk was estimated. However, installation of complementary ventilation systems would be advisable to avoid health risk by acute short-term exposure. Graphical abstract
