From: Reduction of the toxin microcystin-LR with different types of sediments
Effect of several treatments on the desorption of MC-LR, from time 0 (free MC-LR, 100%) to 72 h. Des corresponds to the desorption (is a phenomenon by which a substance is released from or through a surface), equivalent to the final measurement taken after the process used. Whiskers are standard deviations. Different treatments are statistically indicated * p < 0.001
