Fluoranthene　(FLU)　has　gained　much　attention　in　recent　years　because　of　its　continuous　discharge　in　natural　waters　and　toxicity　to　aquatic　ecosystems.　However,　it　is　difficult　to　control　and　manage　FLU　pollution　because　of　the　lack　of　a　rational　and　scientific　water　quality　criteria　(WQC)　of　FLU.　To　solve　these　data　gaps,　the　US　EPA　established　an　interspecies　correlation　estimation　(ICE)　model,　which　can　be　utilized　to　develop　the　SSD　and　HC5　(hazardous　concentration,　5th　percentile).　Moreover,　an　improved　model　was　developed　using　a　combination　of　North　American　ICE　models　supplemented　with　China-specific　species.　In　this　study,　to　verify　the　applicability　of　the　two　ICE　models,　measured　acute　toxicity　data　for　FLU　were　obtained　from　9　acute　toxicity　tests　using　indigenous　Chinese　aquatic　species　from　different　taxonomic　levels.　Original　and　improved　ICE-based　SSD　curves,　which　were　generated　using　3　surrogate　species　(Daphnia　magna,　Oncorhynchus　mykiss,　and　Lepomis　macrochirus),　were　compared　with　SSD　curves　based　on　measured　data.　The　results　showed　that　HC5　was　1.838,　1.062,　and　0.570　mg/L　for　the　original　ICE,　improved　ICE,　and　measured　data,　respectively.　The　improved　ICE-based　HC5　value　for　FLU　was　within　twofold　of　the　HC5　value　based　on　measure　data,　while　the　original　ICE-based　HC5　value　was　threefold　higher　than　the　HC5　value　based　on　measure　data.　This　indicated　that　the　improved　ICE　had　better　predictability　in　extrapolating　data　with　acceptable　deviation　than　the　original　ICE.　Furthermore,　their　differences　between　HC5　derived　from　two　SSD　curves　were　not　significant.　Generally,　the　improved　ICE　model　was　verified　as　a　valid　approach　for　generating　SSDs　with　limited　toxicity　data　and　for　deriving　WQC　for　FLU.
