The implication of this achievement is very significant as it will allow state, local and tribal air monitoring agencies currently performing PM-2.5 surveillance using conventional samplers for regulatory enforcement purposes to replace these samplers with the BAM 1020. Manual samplers for PM-2.5, which typically are operated on one-in-three or one-in-six day sampling schedules in which results were often not known for weeks or months after the event, may now be replaced with the BAM-1020 monitor.
The BAM 1020 monitor produces reliable, accurate, continuous, hourly results in real time. Elevated PM-2.5 events can be determined as they occur (instead of weeks after the fact), which will allow government officials to take timely mitigating action. Daily (vs. one-in-six day) PM 2.5 averages will be available and network operational costs may be substantially reduced.
