Cumulative probability distributions of chemical activities (unitless) of decamethylcyclopentasiloxane (D5) in effluents of D5 production units, ambient water, sediment, plankton, invertebrates, fish, birds, and terrestrial mammals from locations in northern Europe and the United States in relation to the maximum environmentally feasible chemical activity of D5 of 1 (red straight line) and apparent (but unrealistic) chemical activities of D5 greater than 1 corresponding to reported no-observed effects in toxicity assays. Markers depict chemical activities in individual studies. Original data are from Gobas et al. (2015b). NOEC = no-observed-effect concentration.
