platinum and rhodium associated with the leaves of nerium oleander l.; analytical method using voltammetry; assessment of air quality in the palermo (italy) area. | a rapid accumulation of the catalytic active noble metals in the environmental and biological matrices was observed and concern arose about potential environmental and health risks. the development of reliable analytic methods to measure very low pt and rh concentrations is required. the main purpose of this work was to develop a reliable method for the determination of pt and rh in environmental matrices because of inherent difficulties in using conventional techniques used, in particular, the ... | 2010 | 19846253 |
the effects of anthropogenic particulate emissions on roadway dust and nerium oleander leaves in messina (sicily, italy). | complementary studies on the inorganic chemical composition of nerium oleander leaves collected in the town of messina (sicily, italy) and seven grain-size fractions of local roadway dust have been carried out. data and maps are presented to show that the particulate matter present in the air of messina contains trace elements significantly in excess with respect to the average continental earth crust. the anomalies follow the outline of the urban area, the highest concentrations of trace elemen ... | 2003 | 14587847 |
