Which of the following is a potential absorbed toxin?

The correct answer is related to substances that can be absorbed into the body through various means, influencing health negatively. An ant spray typically contains chemicals designed to eliminate pests, which can be toxic to humans if absorbed through the skin or inhaled. These chemicals, once absorbed, can lead to poisoning or adverse health effects.

In contrast, a spider bite can cause localized pain and possibly inject venom, but it is not considered a 'toxin' in the same category as absorbed substances from chemicals. Carbon monoxide fumes, while indeed toxic and dangerous, inhale rather than absorb via the skin, making it less relevant to the context of 'absorbed toxins.' Aspirin, while a medication that can have toxic effects in high doses or improper use, is not categorized primarily as an absorbed toxin from environmental exposure; it is intended for use as a therapeutic drug. Therefore, ant spray stands out specifically as a substance designed for harmful absorption through chemical exposure.
