Estimating Concentration Peaks and Toxic Loads in Hazard Assessment
Acute odour irritation and toxicity from indoor and outdoor airborne contaminants is strongly related to momentary peak concentrations. Dr. Wilson will review the state-of-the-art in estimating fluctuating concentrations and predicting once-per-event peak values. Some rule-of-thumb guidelines will be proposed to allow estimates of 90th percentile exceedence limits, and peak levels knowing only the mean concentration of a naturally dispersing pollutant.
