dc.description.abstract | Although many attempts have been carried out to elaborate trophic magnification factor (TMF) and biomagnification factor (BMF), such as normalizing the concentration of pollutants and averaging diet sources, the uncertainty of the indexes still need to be improved to assess the bioaccumulation of pollutants. This study first suggests an improved BMF (i.e., BMF′) applied to mercury bioaccumulation in freshwater fish from four sites before and after rainfall. The diet source and TP of each fish were identified using nitrogen stable isotope of amino acids (δ15NAAs) combined with bulk carbon stable isotope (δ13C). The BMF′ was calculated normalizing with TP and diet contributions derived from MixSIAR. The BMF′ values (1.3–27.2 and 1.2–27.8), which are representative of the entire food web, were generally higher than TMF (1.5–13.9 and 1.5–14.5) for both total mercury and methyl mercury, respectively. The BMF′ implying actual mercury transfer pathway is more reliable index than relatively underestimated TMF for risk assessment. The ecological approach for BMF calculations provides novel insight into the behavior and trophic transfer of pollutants like mercury. © 2023 | - |
