Question: 1 / 605

What does LC50 stand for in pesticide toxicity assessment?

Lethal Concentration 50%

LC50 stands for Lethal Concentration 50% in pesticide toxicity assessment. This means that this is the concentration of a pesticide that would cause death in 50% of the test population within a specified time frame. Option B, Lethal Concentration 100%, is incorrect because it would mean that 100% of the test population would die at that concentration, making it extremely toxic and not suitable for use. Option C, Lethal Content 50%, is also incorrect as "content" is not used in this context and would not accurately represent the concentration of the pesticide. Option D, Lung Concentration 50%, is incorrect because LC50 does not specifically refer to the concentration of a pesticide in the lungs, but rather the overall concentration that would be lethal for 50% of the test population.
