Concentrations, profiles, and emission factors of unintentionally produced persistent organic pollutants in fly ash from coking processes

- Fly ash was identified as a route of POPs release from the coking industry.
- Emission factors were derived for unintentionally produced POPs in coking ash.
- The data obtained were useful for developing an integrated source inventory.
- Congener profiles for the unintentionally produced POPs in coking ash are presented.
