Lead isotopic ratios (207Pb/206Pb and 208Pb/206Pb) were measured on a sample of Mocs L5-6 chondritic meteorite (from the collection of meteorites of the Museum of Mineralogy of the Babeş-Bolyai University, Cluj-Napoca, Romania), using a inductively coupled plasma quadrupole mass spectrometry method. A NIST 981 standard reference material was used for calibration and control. The obtained data for the standard reference material were within the certified range; the isotopic ratio values measured for Mocs meteorite were 0.8656 ± 0.0084 for 207Pb/206Pb and 2.1011 ± 0.0036 for 208Pb/206Pb and they were compared with other chondritic meteorites. The measured total Pb content was 0.888 ± 0.005 mg/kg. Due to isobaric interferences with 204Hg, 204Pb was excluded, but further method improvement is planned to include all lead stable isotopes due to their importance to geochronology dating.

Urban pollution with trace element occurs mainly in industrial regions and within centres of large settlements where industry, traffic and municipal wastes are the most important sources of trace elements. The results of a first systematic study of spatial distribution of different trace elements in surface soil over the Kavadarci region, Republic of Macedonia, known for its ferronickel mine and metallurgical activities, show some areas with critically high content of some elements. The purpose of this study was to establish contents and distribution of trace elements in attic dust in Kavadarci, and to define them according to geological and anthropogenic influences. Attic dust samples were collected in the rural area. A total of 46 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Eu, Fe, Ga, Gd, Ge, Hf, Hg, Ho, I, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Ni, Pb, Rb, Sb, Sm, Sr, Tb, Th, Ti, U, V, Yb, Zn and Zr) were determined by mass spectrometry with inductively coupled plasma (ICP-MS). Samples of attic dust were collected from October to December 2008 at 31 sites of Kavadarci and its environs. A total of 46 elements were determined. The continuous probability distribution and enrichment ratio for the attic dust samples were studied. It was found that the content for Co, Cr, Mo and Ni in attic dust samples collected around a ferronickel smelter plant are separated by significantly higher values with those from the rest of the samples of the investigated region. © by PSP.
