| Abstract |
The report gives results of measurements of the long-term effectiveness of five unpaved-road chemical dust suppressants. Effectiveness at controlling total particulate emissions in three size fractions was determined over several cycles of chemical application, control effectiveness decay, and chemical reapplication. The chemicals were applied in quantities that spanned the range of common practice in the steel industry. Traffic parameters were typical of the steel industry. Over a 30-day period, control effectiveness of each chemical decreased: in some cases by as much as 50%, and in others by as little as 10%. Control effectiveness for all chemicals was greater than 95% immediately after chemical application or reapplication. |
