      <subfield code="a">Based on workplace exposure data for 16 worker-chemical combinations, the degree of autocorrelation in a series of short-term time-weighted average (TWA) exposure concentrations (7.5-min, 15min. and 60-min TWAs) was investigated. For 7.5-min and 15-min TWAs, consecutive values generally exhibited no correlation or positive correlation, but not negative correlation. The authors discuss a sampling strategy that, on average, would minimize the degree of correlation between measurements of short-term TWAs</subfield>
