Abstract

Abstract: Mercury is known as heavy metals toxic that used in various industrial and mining supply. The extensive use of mercury as amalgamation process caused heavily problems of mercury contamination around the ASGM area. The evaporated mercury from amalgamation process could damage people’s health through inhaling, causing complex health problem such brain damage and death. The aim of this study was to know the distribution of evaporated mercury contamination using tree barks as bioindicator by measuring the mercury concentrations and toxicity levels. The method that used to measure the mercury distribution in tree bark was using Atomic Absoprtion Spectrometer (AAS). The results showed that the total mercury (THg) of Magnolia champaca, Swietenia mahagoni and Anthocephalus cadamba were 56.5, 45.8 and 34.8 µg, respectively. The sampling method used was stratified sampling around the ASGM area and found with a total of 11 trees (one Magnolia champaca, three Anthocephalus cadamba and seven Swietenia mahagoni). Magnolia champaca, Swietenia mahagoni and Anthocephalus cadamba showed high concentrations of THg in the tree bark, which were found at the elevation level of 0-114 m and 114-231 m. This results indicated that the tree barks could be used as bioindicator of atmospheric mercury contaminations. The mercury found in these tree barks indicating that the mercury was spread across around the ASGM area, either the closest to the ASGM or furthest from the ASGM has a high level of mercury toxicity. This shown that the atmospheric condition was in danger because of high atmospheric mercury toxicity. Keywords: ASGM; Distriburion pattern; Mercury; Mining; Tree bark
