• LC50 is the toxicant concentration
that would cause death in 50% of the test organisms
• IC25 is a point estimate of the toxicant concentration that would cause a 25% reduction in test organism growth or reproduction.
• TUa is the reciprocal of the effluent concentration that causes 50 percent of the organisms to die by the end of the acute exposure period. TUa=100/LC50
• TUc is the reciprocal of the effluent concentration that causes no observable effect on the test organisms by the end of the chronic exposure period. TUc=100/NOEC
• NOEC is the highest tested concentration of toxicant to which organisms are exposed in a full life-cycle or partial life-cycle test that causes no observable adverse effect on the test organism.
• LOEC is the lowest concentration of toxicant to which organisms are exposed in a test, which causes statistically significant adverse effects on the test organisms.
• PMSD Percent Minimum Significant Difference.
• MSD Minimum Significant Different
