Probit response of Oreochromis niloticus to acutely toxic concentrations of the pharmaceutical wastewater.

LC5 (mL/L)	LC50 (mL/L)	LC95 (mL/L)	SE	DF	Probit-line equation
15.14 (0.02–29.59)	51.20 (19.14–90.24)	173.21 (96.19–52485.55)	1.32	2

LC₅: lethal concentration that will bring 5% mortality of the exposed population.
LC₅₀: median lethal concentration that will bring about 50% mortality to the exposed population.
LC₉₅: lethal concentration that will bring about 95% mortality of the exposed population.
