摘要We examined transfer patterns of copper (Cu), lead (Pb), zinc (Zn) and cadmium (Cd) in the food web of the Pearl River Estuary (PRE) in southern China using stable carbon and nitrogen isotopes as indicators of energy sources and trophic level (TL) for aquatic consumers. Linear regression of log-transformed concentration of metals versus TL in the estuarine food web was used to determine a trophic magnification factor (TMF). A TMF of 1.52 for Cu was found in the mollusc-crab community, indicating potential Cu biomagnification in this partial benthic food web; whereas a TMF of <1 was found for Cd in the mollusc-crab chain and for Zn and Cd in the whole food web, and a significant negative correlation between the log[Cd] and TL in the benthic food web suggested probable biodiminution of these metals. The TMF varied between a food web and its specific communities, indicating that metal transfer within a food web may possess hiding transfer patterns of metals in specific communities in the PRE. These findings may be extended to other similar ecosystem for providing directions or guidance for the future monitoring and environmental protection policy.
