Platinum group elements (Pt, Pd, Rh) in airborne particulate matter in rural vs. urban areas of Germany: Concentrations and spatial patterns of distribution

Platinum in indoor settled dust matter (homes and cars)

“…The concentrations (mean of three analysis) of Pt in the indoor settled dust samples are shown in with other results [52,53] showing that platinum group elements are likely to be transported by means of air masses to these locations from other source areas. Other studies reported elevated concentrations of platinum group elements in remote locations such as Greenland, as well as other rural locations support this observation [52].…”

A method for determination of PGE–Re concentrations and Os isotopic compositions in environmental materials

“…The presence of PGE in environmental matrices may affect human health and living organisms and, therefore, investigations and developing an understanding of PGE contents in the environment are necessary. Previous studies have shown that PGE concentrations in urban sites are rapidly increasing as compared with natural values, 5,6 and that this trend is related to automotive catalysts.…”

Analysis of Platinum Group Elements in Environmental Samples: A Review

“…with isotope dilution-inductive coupled plasma-mass spectrometry (ID-ICP-MS) for detection of Pt and Pd, providing an extremely sensitive and interference-free determination method. Other PGEs are quantified by using an external calibration (Gómez et al 2003;Alsenz et al 2009;Zereini et al 2012;Ma et al 2013).…”

“…Alternatively, Te co-precipitation for Pt detection (Zereini et al 2012) and Hg co-precipitated for Pd (Alsenz et al 2009;Zereini et al 2012) were described in combination with ID-ICP-MS determination in airborne particulate matter. A direct method for PGE quantification in solid samples is laser ablation ICP-MS. Well homogenized solid rock samples can successfully be analyzed as shown by Gilbert et al (2013) and Osbahr et al (2013) …”
