What is the Inhalation LC50 for a Male Rat?

The Inhalation LC50 (Lethal Concentration for 50% of the test population) represents the concentration of a substance in the air that is expected to cause death in 50% of a defined animal population over a specified exposure time. In the context of toxicity testing, male rats are often used as standard test subjects due to their physiological response similarities to other mammals.

The value of 14,140 ppm is significant because it indicates a specific level at which exposure to a certain chemical can lead to mortality in male rats, providing crucial information for assessing the potential risks of that chemical in industrial environments. Understanding the LC50 helps safety engineers, risk managers, and industrial operators establish safe handling levels and develop appropriate safety protocols to protect workers from harmful exposure.

In this question, the other values do not align with the established benchmarks for the inhalation LC50 for male rats. This highlights the importance of accurate knowledge regarding toxicity levels, as this data can be vital in creating safe workplace conditions and ensuring compliance with health and safety regulations.
