knowledge of the probable origin and behaviour of arsenic certainly gives valuable insights into the potential for transfer in the environment and of the risks involved in mining sites. sequential extraction analyses are common experiments often used to study the origin and behaviour of potentially toxic elements. the method, however, presents some deficiencies, including labor-intensive proced...

The concentrations of five essential elements and six potentially toxic elements were determined in seven organs collected at autopsy from 30 human subjects. Elemental analyses were carried out by graphite furnace atomic absorption spectroscopy, and inductively coupled plasma emission spectroscopy, and inductively coupled plasma mass spectroscopy, and concentrations in fresh and formalin-fixed ...

The aim of study was to integrate chemical analyses and toxicity bioassays in order to assess the environmental risk connected with the presence of trace elements in the sediments. This study examined the ecological significance of trace elements in bottom sediments by applying a set of complementary sediment quality assessment methods sediment quality guidelines (SQGs) (mean probable effect co...
