| Summary: | The danger of lead pollution (Pb) caused by fuel combustion urged the leaded gasoline
phase out policy release which had been implemented in Bandung since July 2006 in
accordance with UU no. 23/1997 and the Regulation of Indonesia’s Minister of
Environment in 2000. The impact of this policy on Pb levels in the air can be examined
through lichen biomonitoring, considering lichen’s sensitivity to air pollution that can be
observed through the accumulation of pollutants in its thallus and changes in its diversity.
This study aims to biomonitor lead pollution in the city of Bandung by measuring lead
accumulation in Lepraria sp. before and after the leaded gasoline phase out policy and
evaluate air quality using the Index of Atmospheric Purity (IAP). This research was
conducted on three roads in Bandung, namely Jl. Panatayuda, Jl. Nyland, and Jl. W. R.
Supratman. Microclimate parameters, traffic density, lichen diversity, and Pb
accumulation in Lepraria sp. using Atomic Absorption Spectrophotometry (AAS) was
measured at each location then compared with the results of research by Robiansyah
(2006). The results showed a decreasing trend in Pb accumulation at all three locations. A
significant increase in temperature and decrease in air humidity was observed, however
microclimate parameters were found to be not correlated with lichen Pb accumulation.
Meanwhile, there was a significant increase in vehicle density which correlated strongly
with lead accumulation. The decrease in lichen Pb accumulation that was observed despite
the increase in vehicle density is thought to be caused by reduced Pb levels in the air due
to the phase out of leaded gasoline. Observation of lichen diversity resulted in the finding
of Lepraria sp., Parmotrema sp., Dirinaria sp., and Candelaria sp. The IAP calculation of
14, 15, and 16 for Jl. Panatayuda, Jl. Nyland, and Jl. W. R. Supratman respectively
indicated high pollution levels at all three locations. |
