On-site laser probe for the detection of petroleum products in water and soil
Article Abstract:
Time-resolved laser-induced fluorescence spectroscopy and fiber optics show potential as tools for detecting environmental pollutants in water and soil. On-site laser probe is useful for practical applications as it is simplified by time-integrated data accumulation of fluorescence intensities in an 'early' and in a 'late' time window with regard to the excitation pulse. Its capability for on-line monitoring of petroleum products is demonstrated in various applications and results from field measurements in an industrial oil separator are reported.

Comparison of AAS, ICP-AES, PSA, and XRF in determining lead and cadmium in soil
Article Abstract:
Potentiometric stripping analysis (PSA) and atomic absorption spectroscopy (AAS) results in an analysis of lead and cadmium in soil agree best among the four techniques, which also include inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and X-ray fluorescence (XRF). Concentrations measured by PSA were higher than those found by AAS, ICP-AES and XRF. Concentrations determined by XRF were lower or equal to those measured by ICP-AES and AAS.
