Health risks support a one-hour airborne particle standard with data acquisition via rapid automated monitoring instrumentation

摘要

Recently evined associations of mortality and morbidity in communities with currently permissible particle mass levels have motivated reconsideration of EPA's particle standard. EPA must deid whether to regulate lower levels, challenging toxicological plausibility. This study inquires whether 24-hour average particle levels might encompass undetected, toxicologically significant excursions.
