Transference of heavy metals (Hg, Cu, Pb and Zn) with the trophic structure in a polyculture pond: evidence from nitrogen stable isotope

Concentrations of heavy metals, including Hg, Cu, Pb and Zn, in sediment and different organisms as well as the transference through the food web in a polyculture pond were investigated. The δ15N values of consumers showed a gradual enrichment with increasing trophic positions from the filter‐feedin...
