Vibrio growth after 24 hours of exposure to triclosan.Vibrio concentrations were normalized to time zero to determine the relative growth after 24 h (T₂₄/T₀). Error bars represent SEM (n = 3). Treatments included no triclosan added (noadd), 0.05% ethanol (solvent), low triclosan (lowt), and high triclosan (hight). Locations were Looe Key Reef, offshore Florida Keys, and Doctors Arm Canal, saltwater canal in the Florida Keys (Figure 2), and Clam Bank Landing, North Inlet Estuary, Georgetown, SC (Figure 1).
