The total petroleum hydrocarbons in sampling sediment analysis by fluorescence spectrophotometry. The concentrations of the TPHs were calculated by the standard curve. The site A3 was next to the leak point. No TPH was detected at site SLR. The symbol An (Bn, Cn): the nst sampling site of line A (B, C); MED: control site in Jiaozhou Bay; SLR: control site in Shilaoren Beach, which was outside of Jiaozhou Bay
