Artemia is a genus of aquatic crustaceans also known as brine shrimp or sea monkeys.It is the only genus in the family Artemiidae.The first historical record of the existence of Artemia dates back to the first half of the 10th century AD from Lake Urmia, Iran, with an example called by an Iranian geographer an "aquatic dog", [2] although the first unambiguous record is the report and drawings ...
This type of toxicity test uses organisms in their most sensitive life stages, usually during times of early reproduction and growth, but not juveniles. [3] The MATC is the highest concentration that should not cause chronic effects, however, for regulatory purposes, a maximum concentration to protect against acute effects must exist as well.
Americamysis bahia is a shrimp-like crustacean in the order Mysida, the opossum shrimps.It is native to estuarine waters in Texas and Florida in the United States. It is often referred to in the literature as Mysidopsis bahia and is widely cultured and used in the laboratory for toxicology testing.
PSP affects those who come into contact with the affected shellfish by ingestion. [1] The toxins responsible for most shellfish poisonings—mainly saxitoxin, although several other toxins have been found, such as neosaxitoxin and gonyautoxins I to IV—are water-insoluble, and heat- and acid-stable.
U.S. Army Public Health Center Toxicology Lab technician assessing samples. Toxicology testing, also known as safety assessment, or toxicity testing, is the process of determining the degree to which a substance of interest negatively impacts the normal biological functions of an organism, given a certain exposure duration, route of exposure, and substance concentration.
This test is the best protocol for testing samples of unknown toxicity, a high level of toxicity, or when the test results are required to provide the highest confidence and precision. This test consists of two controls and eight sample dilutions in duplicate. [14] Acute Toxicity 100% Test is a procedure that tests the sample at 100% sample ...

The resilience of these creatures makes them ideal test samples in experiments. Artemia is one of the standard organisms for testing the toxicity of chemicals [ 10 ] including screening for insecticidal activity – being used by Blizzard et al. 1989 to screen hundreds of semisynthetic avermectins , and by Conder et al. 1992 for the ...
