(a) The Kaplan-Meier Survival plot of Tubifex tubifex upon exposure to various exposure concentrations of CBSF (Chi-square Value 65.31, df 9, P value < 0.0001). The X-axis demonstrates Exposure time (in hours), and the Y-axis depicts the percentage survival of the test animal. (b) Determination. (c) The mean mortality of Tubifex tubifex in 24, 48, 72, and 96 h intervals is depicted by the Box and whisker plot, where the ns represent the non-significant differences (**p < 0.01, and ****p < 0.0001), data represented mean ± SD.
