These compounds were measured in contaminated aqueous soil leachate samples or acetone/acetonitrile extracts of soil and sludge samples. The dynamic range for this assay was 2–30 ppm for phenol and p-cresol. In addition to analysis by the Tyr-CPE detector held at a reducing potential (−0.20 V), soil leachate and extracts were analyzed with the use of a carbon paste electrode (CPE) detector at oxidizing potentials (+1.0 V or +1.2 V). Compared to the CPE, the Tyr-CPE detector was very stable, showing a signal loss of only 28% over 24 h of continuous operation. In addition, the signal from the CPE degraded rapidly by 65% over 10 sequential injections, whereas the signal of the Tyr-CPE decreased by only 5% for the same number of sequential injections. Because of the minimal sample preparation for analysis of soil leachate samples, the herein-reported chromatographic system with biosensor detector could be further developed to complement portable tyrosinase enzyme electrode biosensors that detect total phenols in field settings. © 1999 John Wiley & Sons, Inc.

Daily measurements of PM2.5 were conducted with the DFPSS. Short-term variations in the concentration of PM2.5 were measured and analyzed on site with the use of a tapered element oscillating microbalance (TEOM®) to assess episodic emissions that may have crossed the border. Fine particle carbon measurements, taken with a dichotomous sampler, and meteorological measurements were also performed. Ambient monitoring with these sampling methods was conducted for 1 year at three fixed sites very close to the border of the Lower Rio Grande Valley. Elemental tracer analyses and wind sector analyses were performed to assess transboundary influences. Ad hoc sampler comparisons were also presented. Presentation of advantages and limitations of sampling methods in this study can help establish a baseline for assessing future air quality conditions of a transboundary nature in the Valley. © 1999 John Wiley & Sons, Inc.

The device has been calibrated and tested under field screening conditions for application to waste wood. The analysis for the typical elements contained in common wood preservatives like copper, chromium, boron, mercury, tin, and arsenic has shown a good agreement between the results of classical chemical analysis by atomic absorption spectrometry (AAS) and laser-induced plasma emission spectrometry. Because of the internal calibration relative to the 392.0693-nm carbon II emission line (3p2 P0−4s 2S), the influence of the humidity and the species of the wood on the results of the analysis is negligible. The present detection limits of our method for the common inorganic wood preservatives are, except for mercury, already sufficient for application in the recycling industry. Furthermore, LIPS allows a very high spatial resolution. Therefore, we were able to demonstrate on several different samples that the concentration of wood preservatives at the surface is considerably increased. © 1999 John Wiley & Sons, Inc.

The immunochemical reaction has been carried on using an Immobilon™ membrane as the solid phase.

The extent of the immunochemical reaction has been monitored by means of an electrochemical product using screen-printed electrodes and differential pulse voltammetry (DPV). The screen-printed electrodes were characterized and their electrochemical performance tested. Soil samples were assayed using a simple extraction kit.
