Poisonous is an adjective used to describe something that contains or produces a substance capable of causing harm, illness, injury, or death when ingested, inhaled, or otherwise absorbed by living organisms. The term is commonly associated with substances found in nature, such as plants, animals, or minerals, as well as artificially synthesized chemicals.
When referring to plants, poisonous indicates the presence of toxic substances, known as toxins, that can have detrimental effects on humans, animals, or other plants. Similarly, poisonous animals possess venoms or other toxic compounds that they may use for defense or hunting purposes.
In addition to natural sources, poisonous substances can be artificially manufactured for various purposes. These may include industrial chemicals, household products, medications, or illicit drugs. Exposure to these substances can range from accidental ingestion or inhalation to deliberate use for harmful purposes.
It is important to note that the degree of toxicity may vary depending on the substance and the organism. What may be poisonous to one species can be innocuous or even beneficial to another. Thus, it is crucial to exercise caution and take appropriate measures to prevent exposure to poisonous substances and seek immediate medical attention in case of accidental exposure.
