Polychlorinated biphenyls may alter marine trophic pathways by reducing phytoplankton size and production

Polychlorinated biphenyls may alter marine trophic pathways by reducing phytoplankton size and production

H B O'Connors Jr et al. Science. .

Abstract

Polychlorinated biphenyls at concentrations of 1 to 10 micrograms per liter reduced phytoplankton biomass and size in natural estuarine phytoplankton communities grown within dialysis bags in situ in an estuarine marsh. In polychlorinated biphenyls-contaminated waters, these changes could increase the number of trophic levels and divert the flow of biomass from harvestable fish to jellyfish and other gelatinous predators.
