Half maximal effective concentration (EC 50) is a measure of the concentration of a drug, antibody or toxicant which induces a biological response halfway between the baseline and maximum …

Nov 13, 2019 · EC10. ECx is the effect concentration at which x% effect (mortality, inhibition of growth, reproduction, etc) is observed compared to the control group. It is usually obtained …

If you know the EC50 and Hill slope (H), you can easily compute the EC80 or EC10 or any other value you want. For example, if the Hill slope equals 1, the EC90 equals the EC50 times nine. …

Toxicity tests are used to expose test organisms to a medium—water, sediment, or soil—and evaluate the effects of contamination on the survival, growth, reproduction, behavior and/or …

Jun 17, 2016 · EC50. In ecotoxicity, EC50 (median effective concentration) is the concentration of test substance which results in a 50 percent reduction in either algae growth (EbC50) or algae …

The subscript “eq” stands for “equivalent,” meaning that for each category several endpoints may be available i.e., EC50 eq includes EC50, IC50 (immobilization), and LC50 (lethal); NOEC eq …

Jan 1, 2021 · The relationship between acute (EC50) and chronic (NOEC, EC10) algal inhibition were explored for each data type (r, b, y) (Fig. 4). Endpoints that contained sufficient data to …

EC50 values calculated from N. frigida exposures were consistently lower than those from S. costatum tests for metals, but not 1-methylnaphthalene.

Dec 16, 2020 · EC50 is defined as the concentration at which the response is the mean of the minimum and maximum. For a downward trending (inhibitor) curve, this is also referred to as …

If you know the EC50 and Hill slope (H), you can easily compute the EC80 or EC10 or any other value you want. For example, if the Hill slope equals 1, the EC90 equals the EC50 times nine. …
