Contamination of Heavy Metals (Pb and Cu) at Tin Sea Mining Field and Its Impact to Marine Tourism and Fisheries

Abstract

The dynamics of heavy metals (Pb and Cu) distribution near sea mining locations can show a negative impact on fisheries resource management. The study was conducted at the coastal area of Tanah Merah Beach, Central Bangka Regency, the geographical location at 02o12'50 "S and 106o13'00" E. This study aims to determine the extent of heavy metals (Pb and Cu) distribution adjacent sea mining field and its impact on marine tourism and fisheries. Purposive sampling method was used to identify the sampling locations from 13 closest locations to the farthest from marine mining sources. The result show that the closest and farthest Pb and Cu values from the tin mining activities were 0.16 mg.L-1; 0.03 mg.L-1 and 0.02 mg.L-1; <0.003 mg.L-1. The Hydro-oceanographic conditions from the highest to the lowest water currents of 0.03 m.s-1 - 0.001 m.s-1. This research represented the east monsoon, which showed that the heavy metal distributions dynamics are not too distance-reaching due to weak water currents, so that the dilution and sedimentation rate is slow. It is stated that the waters are polluted where the highest contamination value is indicated by the location closest to the source of marine mining and further weakened at the location farthest from the source of pollutants. Environmental impact from that activity has significantly threatened marine tourism and fishery activities by reducing economic benefits that given from marine and coastal environmental. Urgently, it is necessary to regulate like zoning tin mining activities and sites for the sustainable common purposes and prevent conflicts.

Potensi Kontaminasi Mikroplastik pada Kerang Konsumsi di Pulau Bangka

“…Selain itu, belum ada penelitian dan publikasi terkait kontaminasi mikroplastik pada kerang di perairan Pulau Bangka. Penelitian yang telah dilakukan, sebatas mengkaji potensi kontaminasi logam berat terhadap komoditi perikanan termasuk kerang (Hindarti et al, 2008;Adibrata et al, 2021), kandungan total bakteri kerang darah (Anadara granosa L) hasil budidaya yang melebihi standar PerKa BPOM No. 16 tahun 2016 (Pratiwi dan Sari, 2019).…”

Managing Mangrove Resources in Conflict of Interest Zones in Bangka Island's Eastern Coast

“…The Bangka Belitung Islands Province is one of the world's tin producers (Maia et al, 2019). However, the presence of tin mining has a significant impact on the degradation of coastal ecosystems (Adibrata et al, 2021), especially mangrove forest ecosystems (Sari et al, 2023), and biodiversity (Hasan et al, 2023a;Syarif et al, 2023a;Valen et al, 2023;Kusumah et al, 2023). The area of mangrove forests on the east coast of Bangka Island decreased, from 1, 104.3 hectares (2002) to 964.4 hectares (2017) (Savira et al, 2018).…”

“…The remaining tin mining activities produce tailings that are released into the waters. Waste from mining activities is generally in the form of waste containing heavy metals (Adibrata et al, 2021;Bidayani and Reniati, 2021). Tin mining waste, whether from large-scale industrial operations like suction boats and dredges or from small-scale unconventional mining (TI), has high concentrations of heavy metals, specifically lead (Pb), cadmium (Cd), zinc (Zn) and Chromium (Cr) (Okewale and Grobler, 2023).…”

Distribution and Contamination Level of Cuprum (Cu) and Plumbum (Pb) in Bulk Sediments of the Bangka Island

“…Numerous studies showed the adverse impact of mining activity waste on water quality (Muslih et al, 2014;Komalasari et al, 2019;Adibrata et al, 2021). High turbidity reduces dissolved oxygen (DO) levels and water clarity, thereby slowing down photosynthesis in water.…”
