Table 2.

EC50 values and 95% Confidence Interval (CI) of some chemical activators and inverse agonists of Daphnia HR96.

Chemical	EC50 (μM)	95% CI (μM)	Direction
α-linolenic acid	5.84	DNC	inverse activator
Triclosan	12.0	8.46 – 17.23	inverse activator
Atrazine	1.85	0.66 – 5.16	activator
Docosahexaenoic acid (DHA)	35.6	6.08 – 208.2	inverse activator

DNC: (Did not compute) GraphPad could not compute the 95% CI.

EC50: Concentration of chemicals that increased or decreased DappuHR96 activity to one-half of maximum (activators) or minimum (inverse activators) activity.
