Abstract

Increasing population and economy in Pekanbaru City was clearly followed by anincrease in the number of motor vehicles has the potential to cause air pollution andendanger human health. This research was aimed to analyze the pollutant load gases of CO,HC, NO 2 , SO 2 and PM 10 emissions from motor vehicles at at Pekanbaru City. Survey on thevolume of motor vehicles, roadside air quality and vehicle emission test was conducted onthree different road in Pekanbaru city. The volume of motor vehicles and pollutants loadsfrom motor vehicle emissions was highest at Sudirman road and the lowest at Diponegororoad. There are very significant differences between Sudirman road with Diponegoro roadand Tuanku Tambusai road with Diponegoro road. Higher pollutant load was found for gasCO (76,4 %), than gas HC (19,4 %), gas NO 2 (3,6 %), gas SO 2 (0,1 % ) and PM 10 ( 0,7 % ).The largest contribution of pollutant load gas CO, HC and PM 10 comes from motorcycles, gasNO 2 from the city cars and gas SO 2 coming from the truck. The quality of roadside air in thethird road to the gases CO, NO 2 , SO 2 and PM 10 are still below the ambient air qualitystandards, whilest gas HC had passed the ambient air quality standard. A positive correlationbetween concentrations of roadside air pollutants with a load of motor vehicle emissions wasfound. The percentage of motor vehicle emission test results explain that the rates of vehiclesfueled with gasoline were higher than diesel vehicles and that do not pass of the emission testwere generally produced before 2007, while for diesel vehicles that do not pass the emissionstest opacity value that were produced in the 2010 onward.

Abstract

Bintan Island has a high potential for bauxite mining. Many ex-mining areas have not been reclaimed properly, resulting in erosion and accumulation of heavy metals Pb and Cr which are high in the sediment (red-mud) and deposited in the roots of mangrove forests on the coast of Bintan. Rhizophora mucronata is one of the species that dominates the Bintan mangrove forest. The purpose of this study was to determine the phytoaccumulation of Pb and Cr metals in R. mucronata in the former bauxite mining area ofBintan Island. This research was conducted by survey, digested and analysed using Atomic Absorption Spectrophotometer (AAS). The concentrationof Pb and Cr in the sediment, as well as the roots, stems and leaves of R. mucronata were used for the analysis of phytoaccumulation types. The results of the Pb concentration test were higher than Cr. Based on the sampling location, the concentration of Pb metal accumulation in the sediment is Tembeling <Sei Carang <Wacopek <Senggarang, while Cr metal is Tembeling <Wacopek <Sei Carang <Senggarang. The highest metals accumulation in R. mucronata was found in the roots (Pb = 3,3482 ppm, Cr = 0,7664 ppm), while the leaves (Pb = 1,1076 ppm, Cr = 0,0413 ppm) had the lowest concentration. Based on the type of accumulation, R. mucronata absorbs Pb metal with a rhizofiltration mechanism (TF <1), which means that the roots of R. mucronata effectively translocate Pb as a pollutant to its body from the soil. In addition, the bio-concentration factor (BCF) concentration of R. mucronata <1 indicates the role of R. mucronata as a plant that accumulates very little Pb (low accumulator/non-hyperaccumulator). This adaptation mechanism is important information in the rehabilitation of mangrove areas using R. mucronata, because it can still live and grow in an environment contaminated with Pb metal by absorbing a little Pb from the soil and translocating it effectively in its organs.
