The present research was performed to determine and compare acute toxicity of diazinon and deltamethrin to Spirlin larvae and fingerling. Diazinon and deltamethrin are common usefull agricultural pesticides. LC50 of 24 h, 48 h, 72 h and 96 h was attained by probit analysis software SPSS Version 16. Fish samples (21 fish in each test group) were exp...

... The fish were not fed anything throughout the experiment. Each fish weighed approximately 0.5 g [6,7,9,11]. The OECD 203 standard procedures [12] were followed for conducting the acute fish toxicity test. ...
... The fish behaviour was thoroughly observed, and any dead fish were removed immediately. After 24, 48, 72, and 96 hours, the number of dead fish at each concentration was counted [6,7,9,11]. The concentration required for the death of 50% of the test fish within 96 hours, or the median lethal concentration (LC 50 ), was subsequently determined. ...
An acute toxicity study assessed the LC50 values for eight different amino acid ionic liquids (AAILs), featuring two cations, tetrabutylphosphonium [P4444] and tetrabutylammonium [N4444], coupled with four anions [PHE], [ASP], [SER], and [GLY]. According to the OECD 203 standard for acute fish toxicity tests with guppy fish (Poecilia reticulata, all the AAILs exhibited low toxicity levels, and were practically nontoxic and harmless. The LC50 values surpassed 100 mg/L and 1000 mg/L. This study provides valuable insights for industrial professionals in utilizing tetrabutylphosphonium-based amino acid ionic liquids [P4444] [AA] and tetrabutylammonium-based amino acid ionic liquids [N4444][AA] in chemical processes, indicating their safety in aquatic environments. These promising results highlight the potential of incorporating these AAILs into diverse chemical processes while ensuring minimal ecological impact.
