The toxicity assay of Artemia salina as a biological model for the preliminary toxic evaluation of chemical pollutants

摘要

In order to achieve a good correlation between toxicology and Artemia salina lethality test, several chemical pollutants were examined in A. salina test, with the purpose to use the latter as convenient preliminary protocol for toxic activity. During the test, it was observed the effect of a particular lethal dose or only a knockdown in the arthropod of HgCl_2, KCN, K_2O_2O_7, C6H_6 and C_6H_6Cl_6. The 24h LC_(50) of these five chemical pollutants to the artemia nauplius was 0.12±0.09, 0.06±0.12, 0.72±0.21, 1.57±0.58 and 0.44±0.10 mg/L, respectively. The results of the A. salina lethality test for the chemical substances are essentially in agreement with those described in literature for toxic activity.
