TL;DR: A comparison of platinum-group element (PGE) emission between gasoline and diesel engine catalytic converters is reported within this work, and it is shown that, for fresh catalysts, the release of particulate PGE through car exhaust fumes does not follow any particular trend, with a wide range for the content of noble metals emitted.
Journal ArticleDOI
Levels and risk assessment for humans and ecosystems of platinum-group elements in the airborne particles and road dust of some European cities.

TL;DR: The combined results obtained using a wide-range airborne classifier (WRAC) collector and a PM-10 or virtual impactor show that Pt is associated with particles for a wide range of diameters, and the smaller the particle size, the lower the Pt concentration.
Journal ArticleDOI
Platinum-group elements: quantification in collected exhaust fumes and studies of catalyst surfaces.

TL;DR: The results show that at 0 km the samples collected first have the highest content of particulate PGEs and although the general tendency is for the release to decrease with increasing number of samples taken, exceptions are frequent and at 30,000 km the released P GEs in gasoline and diesel catalysts decreased significantly.
Journal ArticleDOI
Arsenic speciation in environmental and biological samples: Extraction and stability studies
TL;DR: In this article, the authors evaluated the efficiency of consecutive extraction using several individual extractants or solvent mixtures: water, methanol:water (1: 1, 9:1, 1: 1-9:1 in two consecutive steps) and phosphoric acid for arsenic species extraction from rice, fish and chicken tissue, and soil samples.
Journal ArticleDOI
Bioaccumulation of palladium, platinum and rhodium from urban particulates and sediments by the freshwater isopod Asellus aquaticus.
TL;DR: Exposure of Asellus aquaticus to environmental samples for different exposure periods demonstrated that PGE bioaccumulation is time dependent and shows a higher accumulation for the materials with a higher PGE content.
