A landfill-fire plume may need more than the usual benzo[a]pyrene test
WHAT THE EVIDENCE SAYS
Analysis of 13 post-fire residue samples identified multiple parent and alkylated PAHs; benzo[a]pyrene drove modeled direct-contact carcinogenic risk while more mobile fluoranthene drove modeled groundwater concern.
WHY IT MATTERS / OUR READ
Remediation and sampling plans need exposure-route-specific indicator compounds; one pollutant can be an inadequate proxy for all ecological pathways.
CAVEATS / UNCERTAINTY
Risk estimates modeled mobility and exposure; direct groundwater contamination, population impacts and remediation performance were not field-measured.
