“…The heavy metal concentrations tested were Pb and Cr. The status and level of environmental pollution of the ex-bauxite mining area contaminated with heavy metals weredetermined using the Contamination Factor (CF), Pollution Load Index (PLI), and Geo-accumulation Index (Igeo) [9,10,11] with the formula: The results of the measurement of metal content in the sediment were then analyzed for the value of the translocation factor (TF). while the metal values in A. marina were analyzed for the value of the bio-concentration factor (BCF) based on the following equation [12].…”

Bintan Island has high bauxite resource potential. However, its utilization is not balanced with efforts to restore ex-mining land. Physical damage includes erosion and sedimentation of red mud along the coast and the surrounding mangrove forest. This study aims to determine environmental pollution based on the accumulation of lead (Pb) and chromium (Cr) in redmud found in mangrove forests around the bauxite ex-mining area and the adaptation of Avicennia marina to heavy metals. This research was conducted from April to December 2020. Research survey and laboratory analysis using Atomic Absorban Spectrophotometry. The results showed that Pb in the sediments and organs of A. marina was higher than Cr. The results showed that the mangrove forest around the bauxite ex-mining area of Bintan Island was contaminated with low levels of Pb and Cr metals (CF<1, PLI<1) and the environment is lightly polluted (0<Igeo<1). Adaptation of A. marina showed that the metal uptake mechanism was rhizofiltration (BCF<1, TF<1, BCF<TF) and the physical condition was slightly damaged. There was no significant effect between Pb and Cr metals in the sediments and organs of A. marina on the stem diameter and tree height (Sig.> 0.05).

“…The perception of the coastal community greatly determines the level of understanding among the community about the importance of the mangrove area and its sustainable management for the survival of the community. [19][20][21][22] A value of 54.95 obtained from the analysis of the sustainability index for the legal and institutional dimensions indicated sustainability in the management. Based on the leverage analysis, only one of the five attributes, namely the legality of the mangrove forests and the bauxite mine was identified as the lever in the legal and institutional dimensions.…”

Background : The bauxite mining area on Bintan Island continues to expand into the mangrove forest area. Mangrove forests have ecological, economic, and social importance, which must be managed accordingly to maintain their sustainability. This research was conducted to examine the sustainability of mangrove forest management in the former bauxite mining area on Bintan Island. Methods: The approach used is Multi Dimensional Scaling- Rapid Appraisal for Sustainability through the modified Rapfish ordinance software technique for the Mangrove Ecosystem. The type of data used is quantitative, covering five dimensions of sustainability, namely ecological, economic, social, legal and institutional as well as technology. Results: The results showed that the sustainability index status of the ecological, social, legal and institutional dimensions was quite sustainable, while the sustainability index of the economic dimension was unsustainable, and the technological dimension was less sustainable. Attributes of levers that are sensitive to the sustainability of mangrove forest management are: 1) Mangrove density, 2) Substrate fraction, 3) sedimentation, 4) Mangrove importance index, 5) Bio-concentration factor, 6) Benefit value direct, 7) Indirect benefit value, 8) Dependence on mangrove forest as a source of livelihood, 9) Corporate Social Responsibility funding support, 10) Community income, 11) Community health level, 12) Community perception, 13) Legality of mangrove area and mining, 14) Pollution monitoring technology in ex-mining areas and 15) Mangrove rehabilitation technology. Conclusions:The status of the mangrove forest sustainability index on Bintan Island is quite good. the economic and technological dimensions can be upgraded to sustainable status by carrying out management that is more focused on the lever attributes of the ecological, social, legal and institutional dimensions.

“…In addition, the soil of the karst area, compared to that of non-karst area, is characterized by thin regoliths, uneven distribution, and high porosity [ 21 , 22 ], which contributed to the migration of HMs from the surface to the subsoil and even contaminated underground water [ 9 , 23 ]. The process by which HMs entered crops from soils consisted of three stages: the movement of HMs in soils, accumulation of HMs in crop roots and transportation of them to the shoots [ 24 ]. Thus, chemical fractions were indicators of the mobility of HMs and were more meaningful than content with regard to HMs’ biotoxicity [ 25 , 26 ].…”

Exogenous sources and the superposition effect of HMs in agricultural soils made the idenfication of sources complicated in a karst area. Here, a typical watershed, a research unit of the karst area, was chosen as the study area. The smaller-scale study of watersheds allowed us to obtain more precise results and to guide local pollution control. In this study, sources of HMs in agricultural soil were traced by a CMB model. Superposition effects were studied by spatial analysis of HMs and enrichment factor (EF) and chemical fraction analysis. The average concentrations of Cd, Pb, Cr, Cu, Ni and Zn in surface soils were 8.71, 333, 154, 51.7, 61.5 and 676 mg∙kg−1, respectively, which exceeded their corresponding background values. The main sources of Cd, Pb and Zn in agricultural soil were rock weathering, atmospheric deposition and livestock manure, and their contributions were 47.7%, 31.0% and 21.2% for Cd; 7.63%, 78.7% and 13.4% for Pb; and 17.0%, 52.3% and 28.1% for Zn. Cr mainly derived from atmospheric deposition (73.8%) and rock weathering (20.0%). Cu and Ni mainly came from livestock manure (81.3%) and weathering (87.5%), respectively, whereas contributions of pesticides and fertilizers were relatively limited (no more than 1.04%). Cd, Pb, Zn and Cu were easily enriched in surface soils near the surrounding pollution sources, whereas Cr and Ni were easily enriched in the high-terrain area, where there was less of an impact of anthropogenic activities. The superposition of exogenous sources caused accumulation of Cd, Pb and Zn in topsoil, contaminated the subsoil through leaching and improved bioavailability of Cd and Pb, causing high ecological risk for agricultural production. Therefore, Cd and Pb should be paid more attention in future pollution control.
