Fig. 2. NP concentration measured in A) the body of G. pulex (mg g−1), B) faeces of G. pulex per body weight (mg g−1) and C) total NP ingested by G. pulex (mg g−1) per body dw after summing up the concentration of NP in bodies and faeces; after 28 d exposure to NP concentrations in sediment dw (g kg−1). Error bars relate to SE (n = 3). Linear regressions are based on 18 individual data points with grey areas indicating the 95% confidence interval.
