“…The reagent blank acid used in digestion process was monitored throughout the analysis and used to correct the analytical results. The method for digestion process of the sediment samples and SRM (BHVO-1) was described by Elias et al., 2018 [12] . The isotopes of 141 Pr, 158 Gd, 165 Ho, 166 Er, and 169 Tm were measured by using ICP-MS (Perkin Elmer model ELAN 6000).…”

This study is on the distribution of rare earth elements (REEs) concentrations in sediments collected from 113 sampling locations of Linggi River. The analysis of sediment samples was performed by Neutron Activation Analysis (NAA) and Inductively Coupled Plasma – Mass spectrometer (ICP-MS). The main compositions of Linggi river sediments were silt > sand > clay. The mean of total concentrations of REEs (ΣREE), light REEs (ΣLREE) and heavy REEs (ΣHREE) in Linggi sediment were 249, 228, and 22.0 mg/kg, respectively. The results of Linggi river sediment were normalised to several reference shale values. REEs of Linggi river sediments were comparable to MUQ reference shale values. Enrichment factors (EF) of mean values indicate Linggi River sediment can be categorised as having minor to moderate enrichment.

The study of rare earth and actinide elements have received attention nowadays due to rapid development in the extraction of the rare earth industry in Malaysia. Soil samples (18 areas) collected from the Kapar industrial area were analysed by using the neutron activation analysis (NAA) technique for the determination of rare earth elements and actinides (U, Th) concentration. The concentration of rare earth element such as La, Ce, Nd, Sm, Eu, Tb, Dy, Yb and Lu were ranged from 14.7-61.4, 30.6-132.8, 11.7-44.0, 2.12-9.60, 0.37-1.43, 0.03-1.57, 2.20-7.45, 0.28-0.81, and 1.99-4.15 mg/kg, respectively. The concentrations of uranium and thorium were a range of < 0.1-6.74 and 12.6-30.1 mg/kg, respectively. The results of geo-accumulation indicate the all-rare earth elements can be categorised as uncontaminated in all areas with an Igeo value below 0. The concentration of U can be categorised as uncontaminated to moderately contaminated (Igeo class 1) with Igeo values of 0 to 1 in the area of D, F, H, I, L, and N, whilst other areas can be categorised as uncontaminated with Igeo value < 0 (Igeo class 0). The thorium concentration in B, L, and N areas can be categorised as moderately contaminated with Igeo value 1 to 2 (Igeo class 2), whilst most of the area can be categorised as uncontaminated to moderately contaminated (Igeo values 0 to 1). The sources of Th contamination most likely originated from the anthropogenic and geogenic processes.

Matras waters receive input of pollutants from tin mining activities. Heavy metals are toxic and carcinogenic to aquatic biota. Sediment is a carrier of heavy metal pollutants and can act as a “sink” and a “source”. Heavy metals in sediments can reflect the condition/quality of the aquatic system. The purpose of this study was to examine the contamination and ecological risk of heavy metals Cd, Pb, Cu, and Zn in the sediments of Matras waters, Sungailiat, Bangka Regency. Heavy metal test using atomic absorption spectrophotometer (AAS). The concentrations of heavy metals Cd, Pb, Cu, and Zn obtained ranged from 0.02-0.06 mg/kg (average 0.04 mg/kg), 0.12-0.18 mg/kg (mean- average 0.15 mg/kg), each station 0.01 mg/kg (mean 0.01 mg/kg), and 0.54-1.34 mg/kg (mean 0.92 mg/kg ). CF, I-Geo, PLI, and RI values for Cd, Pb, Cu, and Zn metals obtained in Matras water sediments showed low contamination levels (CF<1), not polluted (Igeo 0), not polluted (PLI < 1), and low ecological risk (RI < 150). The EF value obtained indicates the heavy metals Cd, Pb, Cu, and Zn in the Matras waters mainly receiving input from anthropogenic sources (EF value> 1.5). The low ecological risk status which is reinforced by the low values of CF, I-Geo, and PLI indicates that the negative potential of metals to biota is also low. Perairan Matras menerima masukan bahan pencemar dari aktivitas penambangan timah. Logam berat bersifat toksik dan karsinogenik terhadap biota akuatik. Sedimen merupakan pembawa polutan logam berat dan dapat berperan sebagai “sink” and “source”. Logam berat pada sedimen dapat merefleksikan kondisi/ kualitas sistem akuatik. Tujuan penelitian ini untuk mengkaji kontaminasi dan resiko ekologi logam berat Cd, Pb, Cu, dan Zn pada sedimen Perairan Matras, Sungailiat, Kabupaten Bangka. Uji logam berat menggunakan metode spektrofotometer serapan atom (SSA). Konsentrasi logam berat Cd, Pb, Cu, dan Zn yang diperoleh berkisar antara 0,02-0,06 mg/kg (rata-rata 0,04 mg/kg), 0,12-0,18 mg/kg (rata-rata 0,15 mg/kg), setiap stasiun 0,01 mg/kg (rata-rata 0,01 mg/kg), dan 0,54-1,34 mg/kg (rata-rata 0,92 mg/kg). Nilai CF, I-Geo, PLI, dan RI untuk logam Cd, Pb, Cu, dan Zn yang diperoleh pada sedimen Perairan Matras menunjukkan tingkat kontaminasi rendah (CF<1), tidak tercemar (Igeo 0), tidak tercemar (PLI <1), dan resiko ekologi rendah (RI < 150). Nilai EF yang diperoleh mengindikasikan logam berat Cd, Pb, Cu, dan Zn perairan Matras utamanya mendapat masukan dari sumber antropogenik (nilai EF>1,5). Rendahnya status resiko ekologi yang diperkuat dengan rendahnya nilai CF, I-Geo, dan PLI menunjukkan potensi negatif logam terhadap biota juga rendah.
