With these evaluations, the acute toxicity profile of a new drug candidate molecule can be predicted using several suitable databases when structural similarities are found in it. According to the in silico methods mentioned above, a chemical with an LD50 value >2000 mg/kg could be predicted very...

Acute toxicity refers to the potential harm caused by a substance when it is encountered in high doses over a short period of time. In the case of riboflavin, there are no reports of acute toxicity even with exposure to high amounts. ...
Because calcium is a primary ion influencing water hardness and there is widespread calcium decline in lakes, we examined the effects of varying calcium concentrations on acute salt toxicity in three Daphnia species to gain a greater understanding of the water hardness–salt toxicity relationship. We...
