Abstract
The monitoring program monitored the indoor particulate matter concentrations
of the PM0.5, PM1.0, PM2.5, PM5.0, PM10.0, and TPM. Two hospitals were selected in this
study. Particulate matter concentrations were collected at Hospital Parit Buntar and
Hospital Sungai Bakap. The concentration of all the particulate matter was monitored at
the outpatient department of the hospital. Other existing possible sources around the
monitoring location were considered to determine whether it will affect the concentration
of particulate matters. The monitoring program was launched on January 22, 2019, until
January 25, 2019. The monitoring data at the outpatient department was taken with a
minute interval. Lighthouse Handheld 3016 – IAQ, formaldemeter and Air Flow were
positioned at the outpatient department. The data recorded using the specification
monitor were analyzed using SPSS software to determine the concentrations and
variations of indoor particulate matters at selected hospitals. The meteorological
parameters were analyzed using Pearson Correlation to investigate the relationships
between weather parameters and particulate matter concentration. Based on the
apportionment analysis, the contribution of meteorological sources such as the
temperature, relative humidity, and wind speed are not really strong based on the result
analyzed using Pearson Correlation. From the analysis, model particulate matter with
weather parameters was created using Multiple Linear Regression (MLR). Based on the
model, R2 value ranging from 0.3133 - 0.8874 for Hospital A and 0.7604 – 0.9243 for
Hospital B. This shows the model fits the concentration in Hospital B better than in
Hospital A. The type of ventilation system for both hospitals and also the outdoor sources
can affect the concentration of particulate matter.
