Here's a breakdown:
* Toxicity refers to the degree to which a substance can cause harm to living organisms. It's a measure of how poisonous something is.
* Toxic substances are those that can cause adverse effects on living organisms, ranging from mild irritation to death.
* The level of toxicity can vary depending on factors like:
* The substance itself: Different chemicals have different levels of toxicity.
* The dose: The amount of substance that is ingested or absorbed.
* The route of exposure: How the substance enters the body (e.g., ingestion, inhalation, skin absorption).
* The individual's sensitivity: Some individuals may be more susceptible to the effects of toxins than others.
It's important to note that toxicity is not an all-or-nothing concept. Even substances that are considered relatively safe can be toxic at high doses.
