Mean concentration (± 1 SE) of DMSP (as µmol DMSP per g of algal dry mass [DM]) in U. fenestrata after exposure to acrylic acid (grey bars), and DMS (black bars) 1, 3, 7 and 11 days after exposure to the compounds. White bars are DMSP concentrations near control emitters. Horizontal bars below the x-axis indicate means that are not significantly different from one another (post hoc Tukey’s test, P > 0.05).
