Figure 2

Cellular quotas of chlorophyll a (a,b) and carotenoid content (c,d) (pg cell−1) of Chlorella vulgaris (a,c) and Skeletonema costatum (b,d) cells at different phenanthrene concentrations. The data are means ± SD of triplicate cultures (n = 3). The different lowercase letters indicate significant (p < 0.05) differences between phenanthrene concentrations in one species (one-way ANOVA and post-hoc Tukey tests).
