Atmospheric Pollution
In the atmosphere, the existence of large quantities of undesirable substances that could cause several health issues to living organisms and humans is atmospheric pollution. Air pollution is otherwise known to be atmospheric pollution. The presence of undesirable materials would also destruct the natural environment such as a change in climate, degradation of habitat, or depletion of ozone. Air pollution is generated by the natural processes and activities of humans.
Smokestack Scrubbers
Once we believe in the environment and remember the pollution-producing facets of it, we will consider the smoke-stacks scrubber to be a number of the worst offenders. Although this is often legally correct, smoke-stack scrubbers often have a big function in terms of keeping ground-level air pollutants- safe to breathe and assisting within the management of emissions.

Transcribed Image Text:Case Study: Temporal Analysis of Environmental Noise and Air Pollution
Nearby a Government Hospital in Suburban Klang Valley, Malaysia.
ABSTRACT
Introduction: Exposure to ambient noise and air pollution from road traffic has been
associated with an increased risk of adverse health effects, such as heart disease and
mental health. Although recent studies have identified temporal variations of noise
and air pollution in urban areas, there has been limited data on the levels within
sensitive areas such as a hospital. Thus, this study presents the scenario of noise and
air quality level in the temporal dimension assessed near a hospital located in the
suburban area of Klang Valley, Malaysia.
Methods: A-weighting noise level (dBA) 3M™ EdgeTM 5 Personal Noise Dosimeter and
PM2.5 concentration Dusttrak II Handheld Aerosol Monitor Model 8523 (µg/m³) were
measured simultaneously with a l-min interval. All measurements were taken from
0700 hrs until 1900 hrs on weekdays and weekends.
Results: High noise level (min= 61.1 dBA, max= 62.0 dBA) and PM2.5 concentrations
(min= 20 µg/m³, max= 29 µg/m³) were observed during morning peak hours on
weekdays and weekends. Noise levels measured are exceeded the Department of
Environment (DOE) guideline limit (55 dBA) and PM2.5 concentrations complied with
the annual standard (35 µg/m³). We observed moderate correlations between noise
and particulate pollution PM2,5 during weekdays and weekends (r= 0.66, p<0.01).
Discussion: Our findings suggest that people who work or spend most of their time
outside (i.e. outdoor workers) are more susceptible to noise and air pollution than
people who live away from major traffic zones. Both pollutions are likely to be harmful
to the health of nearby residents, pedestrians, cyclists, and outdoor workers. However,
the indoor environments of the hospital can be affected from the outdoor sources
including construction and traffic noise and air pollutants.
Conclusion: Noise level and PM2.5 concentration varied widely over time and could
have a negative impact on human health. Our case study recommends that
measurement of both noise and air pollution deserved further investigation to allow
detailed exposure characterization of this relationship.
