摘      要：The bioaccumulation of mercury(Hg)in aquatic ecosystem poses a potential health risk to human being and aquatic *** by plankton represent a crucial process of Hg transfer from water to aquatic food ***,the current understanding of major factors affecting Hg accumulation by plankton is *** this study,a data set of 89 aquatic ecosystems worldwide,including inland water,nearshore water and open sea,was *** factors influencing plankton Hg bioaccumulation(i.e.,plankton species,cell sizes and biomasses)were *** results indicated that total Hg(THg)and methylmercury(MeHg)concentrations in plankton in inland waters were significantly higher than those in nearshore waters and open *** factors for the logarithm of THg and MeHg of phytoplankton were 2.4–6.0 and 2.6–6.7 L/kg,respectively,in all aquatic *** could be further biomagnified by a factor of 2.1–15.1 and 5.3–28.2 from phytoplankton to *** MeHg concentrations were observed with the increases of cell size for both phyto-and zooplankton.A contrasting trend was observed between the plankton biomasses and BAF_(MeHg),with a positive relationship for zooplankton and a negative relationship for *** physiologic traits impose constraints on the rates of nutrients and contaminants obtaining process from ***,many aquatic ecosystems are facing rapid shifts in nutrient *** suggested that these potential influences on the growth and composition of plankton should be incorporated in future aquatic Hg modeling and ecological risk assessments.
