According to the textbook, “toxin usually refers to a toxic substance made by living organisms including reptiles, insects, plants, and microorganism and a toxicants are toxic substances that are man-made or result from human (anthropogenic) activity” (Friis, 2010, p. 52). Some examples of toxin are poisonous mushrooms, poison ivy, drinking too much water, and pollution. Next, some toxicants would be pesticides such as DDT, and industrial chemicals. In my opinion, a toxin is different from a poison because a toxin is a poison made by a living organism and a poison is a substance that is known to be deadly to any living being.
