Responses of molluscan communities to centuries of human impact in the northern Adriatic Sea
Fig 3
Grain size analysis and concentrations of several metals, nutrients and organic pollutants.
Dashed lines indicate threshold values for potential environmental effects according to NOAA sediment quality guidelines and to the Italian Ministerial Decree 26/2010 (ERL: Effects Range-Low; ERM: Effects Range-Median; TEL: Threshold Effects Level). For PAHs, no thresholds are plotted because measured concentrations are considerably lower.
