ABSTRACTA method has been developed to analyze mercuric iodide (HgI2) for elemental contamination using Inductively Coupled Plasma/Mass Spectroscopy (ICP/MS). This paper will discuss the ICP/MS method, the effectiveness of purification schemes for removing impurities from Hgl2, as well as preliminary correlations between HgI2 detectorperformance and elemental contamination levels.

Heavy metal contaminants in fish are of particular interest because of the potential risk to humans who consume them. The edible muscles of eight different species of fishes were analyzed by ICP-MS (Inductively Coupled Plasma Mass Spectroscopy) for heavy metals, collected from Market in Gwangju, Korea during April-May in 2008. The concentrations of Hg, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn varied between 0.24±0.007 - 0.01±0.001, 44.54±5.69 - 1.23±0.20, 0.13±0.05 – ND (not detected), 1.32±0.47 - 0.09± 0.02, 3.13±2.53 - 0.63±0.06, 107.17±28.02 - 11.27±1.56, 12.38±1.23 - 0.25±0.02, 1.025±1.41 - 0.12±0.09, 0.74±0.28 - 0.05±0.03 and 80.30±17.09 - 22.35±6.89 mg/kg, respectively. The concentrations of arsenic and nickel exceeded the maximum allowable intake level. Keywords: Heavy metals; Marine fish; Korea. © 2010 JSR Publications. ISSN: 2070-0237 (Print); 2070-0245 (Online).

The emergence of mass-spectroscopy with inductively-coupled plasma (ICP-MS) made it possible to study the microelement composition of crude oil and its derivatives with the limit of detection (LOD) at the ppt level. We have studied the crudes from West Siberian (Shaimsky, Sredneobsky and Oktyabrsky regions) and Tatarstan Romashinskoye oilfields with the ICP-MS method to detect 50 rare, rare-earth, and other microelements. The elemental composition is reasonably comparable to their concentrations in ultrabasites whereas the contents of most of the elements are low to the limit. On the diagrams of rare-earth elements, one can see the prevalence of light lanthanides and positive europium anomaly. Increased content of platinoids was found in Tatar oils; in some cases, the concentration of ruthenium reaches 0.06 g/t. The study shows that studied crudes have a specific microelement composition. Based on the elevated contents of transit elements and platinoids, a conclusion was made about the “ultrabasic” geochemical–metallogenic specialization of studied petroleum systems and the assumption about its origin was proposed.

The study aims to assess the chemical composition of sulphurous spring waters collected from Pucioasa � Vulcana Bai balneotherapeutical area, Dambovita County. The sampling were achieved from active and preserved sulphurous sources (i.e. five springs), during the summer period of the year 2016. The content of nine metals (i.e. Cr, Mn, Fe, Co, Ni, Cu, Cd, Zn, and Pb) in water samples was determined by Inductively Coupled Plasma - Mass Spectroscopy (ICP-MS). The relationships between physicochemical parameters (i.e. pH, conductivity, TDS, salinity, total hardness and dissolved oxygen) and metal concentrations were investigated, as well.

Penelitian ini dilakukan dengan tujuan untuk mengetahui kemampuan alga spesies Caulerpa serrulata dan Halimeda macroloba sebagai agen fitoremediator merkuri di perairan laut. Analisis merkuri pada sedimen dan jaringan alga berdasarkan metode standar United State Environmental Protection Agency (USEPA) yang dilakukan di Water Laboratory Nusantara (WLN) dengan menggunakan Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) instrument. Hasil penelitian memperlihatkan bahwa Caulerpa serrulata mampu mengabsorbsi merkuri sebanyak 0,20 ppm dan Halimeda macroloba mampu mengabsorbsi sebanyak 0,11 ppm dari perairan Teluk Totok. Selain itu kemampuan Caulerpa serrulata dan Halimeda macroloba mentoleransi kadar merkuri yang tinggi di sedimen tempat alga tersebut tumbuh bisa menjadi pertimbangan bahwa alga tersebut memiliki potensi untuk dapat digunakan sebagai salah satu organisme fitoremediaotor merkuri di perairan laut.
