Abstract

Abstract: MPTS plants cultivated by the community were suspected contaminated by mercury used in gold refining. Bark can be used as a bioindicator for mercury pollution in the atmosphere. The research objective was to determine the concentration of mercury contamination in MPTS plants and types of plants that have the potential as atmospheric mercury bioindicators. This study used a pathway method for sampling with an area of 387.03 ha and used Atomic Absorption Spectrophotometry (AAS) to analyze the mercury concentration in tree bark. The results showed that Tamarindus indica, Persea americana, and Annona muricata were accumulated the high mercury concentrations compared to the other types of MPTS plants. The Tamarindus indica, Persea americana, and Annona muricata were accumulate 74.4, 58.7 and 44.2 µg total mercury (THg), respectively. It is known that the bark of MPTS trees at low altitude contains more mercury in terms of the location of the tree. This is influenced by various factors such as skin characteristics, height, and natural conditions. This shows that the activity of refining gold using mercury has polluted the environment of Bunut Seberang Village and some plants are able to accumulate mercury in the atmosphere.
