Lab report - Essay ExampleThe results shows the regard ass for fatal Concentration 50 and Lethal Dose 50. From the table of Lethal Concentration 50, Ammonium nitrate is the most fatal most knockout of the four compounds. This is because the compound has the lowest value and this means that it becomes lethal at take down concentration that the other compounds. the conclusion is valid because of measures that consider data on a uniform scale. All measures are with respects to rat and inhalation and this provides pit base for measuring effectiveness of the compounds. Sodium chloride is the next dangerous compound as it becomes lethal, to cause 50 percent deaths, at 42 ppm. Larger concentrations, more than 1000 ppm are however required for carbon tetra chloride and hydrofluoric acid and this means that the two compounds are less dangerous with respect to the test animal. The observation croup therefore be inferred to other animals to the conclusion that, with respect to Lethal Co ncentration, Ammonium nitrate is the most dangerous of the compounds followed by sodium chloride.Data on lethal dose 50 however identifies the least value with sodium chloride, 3 mg/kg, and this means that the compound is the most dangerous of the four. Hydrofluoric acid follows this with a value of 25 mg/kg. carbon tetrachloride and Ammonium Nitrate however have very high values that indicates lower toxixity. The conclusion is further reliable, based on the data, because measures are taken on the same scale, in relation to a single animal species, and in relation to similar delivery mode.A inconsistency is however noted in the trend of toxicity of the four compounds. while values for Lethal Cconcentration 50 identifies Ammonium nitrate as the most dangerous followed by sodium chloride, values of Lethal Dose 50 identifies sodium chloride as the most dangerous followed by hydrofluoric acit. A possible explanation to the
