摘要

Three recent publications provide an excellent summary of the state-of-the-science on the measurement and potential applications of trophic magnification factors (TMFs) for the assessment of chemical bioaccumulation in food webs. TMFs are useful measures of trophic magnification and represent the diet-weighted average biomagnification factor (BMF) of chemical residues across food webs (Figure 1). Empirical TMFs are currently derived from field measurements whereby providing information on the actual behavior of the chemical in the environment. The TMF is typically derived from the slope of a log-normal regression of chemical residues in organisms upon their corresponding trophic levels.
