Inductively coupled plasma spectrometry in the study of childhood soil ingestion. Part 1. Methodology
Abstract
The methodology developed with inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS) and its verification for the routine determination of eight elements (Al, Ba, Mn, Si, Ti, V, Y and Zr) in biological (faeces and urine), environmental (dust and soil) and food samples related to childhood soil ingestion are described. Sample manipulations for diapers, dust, food, faeces, soil and urine preparation and analysis are presented. Quality control results with reference materials (mixed diets, dust and soil) and standard solutions are summarised.
