Besides to impact on changing of landscape and biodiversity, tin mined left heavy metal contaminants,and phytoremediation (the use of plants to accumulate heavy metals) is a chosen method. This studymeasures Pb (Lead), Cu (Copper), Zn (Zinc) in soil and dominant terestrial plants in tin mined landand Fe (Iron), Al (Aluminum), As (Arsen) in root and shoot of dominant plants in ex-tin mined pond.Dominant species was determined by vegetation analysis of quadrate method. Metals analysis wasconducted using atomic absorption spectrophotometry. Pb in secondary forest (8 ppm), in revegetatedtin mined soil (10,80 ppm) and in 0 year abandoned tin mined soil) (20,70 ppm) exceed qualitystandards. There is no potential of becoming accumulator plant for Pb, Cu, Zn in tin mined land, butSchima wallichii was found potential to be Cu accumulator in secondary forest because it hastranslocation factor (TF)>1. The highest Fe > 2% in shoot and > 3% in roots. Al > 2% in shoot and >3% in root. As was not detected.Keywords: Tin mined soil, Bangka, Metal, Accumulator plants

As one of the island that producing tin ore mineral (cassiterite), Bangka Island has probably a bigpotential of tin associated mineral that contains radioactive elements like Thorium (Th) and Uranium(U). Th and U can be one of potential future prospect elements expecially for nuclear energy. Th andU elements bearing minerals in Bangka Island not yet exploited. They take out from the tin ore miningand becoming tailing, and then through the surface water flows or shallow sea water as sediment. Thestudy goal is to getting the number of radioactive Th and U elements using surface sediment sampleand then interpretation some part of their spatial distribution form. The Surface sediment data hasbeen collected on 2 sites Kolong in Muntok District West Bangka Regency, 3 sites in MerawangDistrict Bangka Regency, 9 sites in Pangkalpinang City, 2 sites in Central Bangka Regency and 2sites in South Bangka Regency. Chemistry analysis of sediments for identification the presence of Thand U elements. Radioactive element of Uranium (U) almost presence at all shallow surfacesediment 4.842 - 229.2 ppm except nul in 1 sample. Thorium (Th) just presence in a part of sedimentsample. One site as especially case study Kacang Pedang Retention Ponds, shows Th and Uradioactive elements has the heterogenity spatial pattern.

The research sites are located in the village of Berambang, Sekotong District, West Lombok Regency,West Nusa Tenggara Province. This area was dominated by volcanic rocks composed of dasiticvolcanic rock, diatrema breccia, and diorite intrusion. Berambang area shows alteration in the form ofpotassic, propylitic, advanced argillic, and argillic alterations where in some places accompanied bypyritisation and stockwork structure, the type of mineralization in this area is a porphyry copper-goldtype. In the potasic alteration zone there are minerals that have a strong anomaly response to themagnetic due to the presence of oxide minerals magnetite (Fe2O3). Mineral sulfides such as pyrite(FeS2) and chalcopyrite (CuFeS2) will also provide significant anomalous responses that have anabundance of 2-5% in the potassic zone. In a propylitic alteration zone characterized by chlorite,calcite and epidote minerals that do not respond to magnetic anomalies, the presence of pyriteminerals, hematites and chalcopyrite with abundance of ≤1% will provide some magnetic anomaly inthe propylitic zone. As for advanceargillic alteration zones characterized by mineral andalusite, aluniteand quartz, there will not be any magnetic anomalies, the phenomena was due to the rarity ofmineralization in this zone gives an insignificant anomalous impact. Meanwhile, for the argillic zonecharacterized by mineral illite, kaolinite and smectite will not have anomalous magnetic impact, veryrare mineralization in the argillic zone so that the magnetic anomaly is not significant. From the floatingEuler 3D shows an anomalous source from a depth of 0 meters to a depth of more than 400 meters.
