  • Recent studies highlight the role of intermediate/semi-volatile organic compounds from asphalt in forming secondary organic aerosols (SOAs), but results vary widely.
  • This research aims to provide more accurate emission factors for roofing materials' contributions to SOA formation by examining affecting variables like rooftop temperatures and material properties.
  • The findings estimate that asphalt roofing produces significantly lower SOA emissions compared to mobile sources like diesel and gasoline, with a central tendency of 1.7 × 10 Gg/yr for the hottest hours in Southern California.

Article Synopsis
  • The study assesses a new algorithm for identifying Long COVID in pediatric patients, aiming to standardize how this condition is defined and recognized in the medical community.
  • Using data from 31,781 patients, the algorithm showed moderate accuracy when compared to traditional chart reviews, with an overlap rate of 62%, but also noted significant disagreement on cases.
  • The findings suggest that discrepancies may stem from varying interpretations of Long COVID symptoms, emphasizing the need for a clearer clinical definition to improve identification and support research efforts.
