Pennsylvania construction employment and monitored PM2.5, 2023

Archived study

Combines Pennsylvania construction employment and monitored PM2.5 for 2023. Of 247,962 payroll jobs, 65,246 (26.3%) were in counties without an eligible annual PM2.5 value. Eligible monitoring covered 23 of 67 counties.

Interpretation and limits

County ambient summaries are not workers’ individual exposures or regulatory attainment estimates. Missing monitoring is not zero pollution. Coverage rules and site aggregation affect categories; a later, narrower-basis rerun is not merged into this version.

Package and provenance

The unchanged research package comes from upstream Case 24. It includes the archived session, analysis materials, results and figures. The poster uses an AI-generated illustrative photograph. This introduction summarizes archived findings; the analysis was not rerun.

Import provenance

This case was added to the Academic Research category on 2026-10-13, with the archived upstream case recorded as its source. The supplied session export and poster were uploaded without changing their contents. This introduction summarizes the archived findings and was standardized for the repository. The study, external data sources, and scientific results were not rerun or independently reverified for this import.

This GitHub catalog imports the case from the verified Hugging Face snapshot. The session export is referenced through that fixed revision; the cover and introduction are stored in this repository.
