Abstract
Abstract
An interlaboratory study of a graphite furnace atomic absorption spectrophotometry (GFAAS) method for the determination of lead in wine was conducted. Seventeen laboratories from France, United States, and the United Kingdom, using a variety of GFAAS instruments, took part in the study. The method incorporated a novel matrix-matching procedure to minimize matrix effects between standards and samples. Six wine test materials were prepared and sent to participants as 12 blind duplicate or split level samples. There was good agreement between results obtained from participants and target values (24–279 μg/L) obtained with an inductively coupled plasma-mass spectrometry method. The precision of the GFAAS method was well within the range predicted by the Horwitz equation for the 6 test materials analyzed. Repeatability standard deviations ranged from 3 to 17%. Reproducibility standard deviations were in the range of 10 to 30%. The method is recommended for use for official purposes.

Abstract
We studied heart rate variability (HRV) using spectral analysis techniques in 58 adult patients recovering from general anaesthesia. The aim was to discover how HRV was affected by a variety of common preoperative, intraoperative and postoperative factors. ECG, respiration, level of consciousness, nausea, pain and arterial pressure were recorded during the first hour of recovery from general anaesthesia. HRV was found to decrease with increased weight, age, complexity of operation, use of reversal agents for neuromuscular block and preoperative beta-block. These effects were not mediated by changes in respiration. HRV was unaffected by administration of morphine. The level of nausea or pain had no effect on HRV except that pain decreased the relative ratio of high frequency to low frequency power within the power spectrum. In the group of patients that did not receive reversal agents, there was an abrupt increase in HRV when patients became responsive to verbal command.
