Traffic air pollution monitoring based on an air–water pollutants deposition device
Silva, L.T.; Pinho, J.L. & Nurusman, H.
Abstract
An air water surface sampler device was
developed and used to evaluate the atmosphere deposition
due to the urban traffic air pollution in the business center
of a mid-sized city. The indicator adopted to assess the
cumulative air pollutant deposition in the surface of the
device was the electric conductivity that was measured on a
regular basis during the experiment. Additionally, a digital
camera was used to count the passing traffic in the road of
the study site. Water samples were also taken from the
device reservoir, and dissolved metal concentrations
(copper, iron and zinc) and acidity/alkalinity were determined
in the laboratory. The obtained results were compiled
and analyzed in order to evaluate the performance of
the device and the relation between the atmospheric
deposition and the traffic activity under different meteorological
conditions. The research successfully proved that
the device was able to evaluate the impact of pollutant
emissions related to city traffic. It was also proved that
electric conductivity can be used as an indicator to evaluate
the cumulative deposition of air pollutants from road traffic.
A significant correlation (Spearman’s rank) between
the accumulated traffic and electric conductivity (dry period:
ᵨ = 0.991626 and wet period: ᵨ = 0.810526) was
observed.
