Diversity of fluoranthene/(fluoranthene plus pyrene) (FL/(FL + PY)) ratios among petroleum coke, raw oil sand, and stack emissions obtained from the peer‐reviewed literature and the NPRI (National Pollutant Release Inventory: https://open.canada.ca/data/en/dataset/40e01423-7728-429c-ac9d-2954385ccdfb); NPRI stack emissions (“source testing” for “stack/point” and “releases to air”) for Suncor Basemine (SBM) and Syncrude Mildred Lake are median (range)
