PERBANDINGAN KADAR KARBON MONOKSIDA (CO) DAN NITROGEN DIOKSIDA (NO2) DI UDARA AMBIEN BERDASARKAN KEBERADAAN POHON ANGSANA (Pterocarpus indicus) DI BEBERAPA JALAN RAYA DI KOTA MEDAN TAHUN 2012
Abstract: Comparison levels of
carbon monoxide (CO) and nitrogen dioxide (NO2) in the ambient air depend on of
Angsana tree (Pterocarpus indicus) in the some road in Medan city in 2012. The
main pollutant produced by vehicles is carbon monoxyde (CO) and nitrogen
dioxyde (NO2). Carbon monoxida (CO) and nitrogen dioxyde (NO2) is a parameter
change in air quality, in case of eleveted levels of this materials in the air
exceeds the quality standars that have been set can cause health problems for
humans. The aim of this research was analyize concentrate of carbon monoxyde
(CO) and nitrogen dioxyde (NO2) ambient on highways based on the existence of
Angsana tree (Pterocarpus indicus). The result of research the highest
concentration of carbon monoxyde (CO) was found on the highways planted Angsana
(Pterocarpus indicus) is Jl. A.H Nasution and on highways that are not planted
Angsana (pterocarpus indicus) is Jl. Asia 16.033 ug/Nm³ and the lowest
concentratin of carbon monoxyde (CO) was found on the highways planted Angsana
(pterocarpus indicus) is Jl. Brigjend Katamso 4.581 ug/Nm³. The highest
concentration of nitrogen dioxyde (NO2) was found on the highways are not
planted Angsana (Pterocarpus indicus) is Jl. S. Parman 29,78 ug/Nm³ and the
lowest concentration of nitrogen dioxyde (NO2) was found on the highway planted
Angsana (Pterocarpus indicus) is Jl. A.H Nasution 9,22 ug/Nm³. In could be
concluded that concentration of carbon monoxyde (CO) on the highway planted
Angsana trees (Pterocarpus indicus) and on roads in which there was no Angsana
tree planted was similar, the highest concentration of nitrogen dioxyde (NO2)
was found on the highway that are not planted Angsana tree (Pterocarpus
indicus) planted. For the reason, it would be nescessary to grow some trees
that can absorb excessive gas carbon monoxyde (CO) and nitrogen dioxide (NO2)
especially on roads in which the passing through vehicles are very active.
