Linearity of response results. MC-LR was spiked into thickened sludge at 0.5, 1.0, 2.0, 3.0, and 4.0 μg/L. Data points and error bars represent the means of duplicate spiked samples and average deviations about the means, respectively. Each panel represents a different water quality prior to coagulant addition.
