What is a 'toxicant' in the context of pesticides?

A protective gear worn during pesticide application.
A chemical compound that enhances soil fertility.
A term for pesticides used in toxic waste cleanup.
A poisonous substance such as the active ingredient in a pesticide formulation.

The correct answer is: A poisonous substance such as the active ingredient in a pesticide formulation.

Toxicant refers to a poisonous substance that can cause harm or toxicity to living organisms. In the context of pesticides, it specifically refers to the active ingredient of a pesticide formulation that is designed to kill or control pests. Option A is incorrect because protective gear is not a toxicant itself. Option B is incorrect because a chemical compound that enhances soil fertility would not be considered a toxicant, as it does not pose a risk to living organisms. Option C is incorrect because while pesticides may be used in toxic waste cleanup, "toxicant" specifically refers to the active ingredient in pesticides, not the application or use of them.
