Materials that damage particulate are referred to as irritants. This special class of irritants, including chemical reagents and commonly encountered substances, can damage the lungs and cause scar tissue formation, which lowers respiratory capacity. None of the above options are correct for this statement. Chemicals that interfere with oxygen distribution and uptake activity, causing a decrease in oxygen levels, are commonly referred to as asphyxiants. Inert chemicals such as nitrogen and halothane, which displace oxygen in enclosed spaces, are also considered asphyxiants. None of the above options are correct for this statement. Substances that activate the immune system and cause allergic responses may not be directly antigenic themselves, but they can make other materials antigenic. These substances are commonly referred to as allergens. None of the above options are correct for this statement. Toxic substances that specifically poison nerve cells are commonly referred to as neurotoxins. None of the above options are correct for this statement. Chemicals or other factors that cause abnormalities during development are commonly referred to as teratogens. None of the above options are correct for this statement. Substances that cause cancer are commonly referred to as carcinogens. None of the above options are correct for this statement. Poisoning by a single exposure to a toxic chemical is commonly referred to as acute poisoning. None of the above options are correct for this statement. Any poisonous effect produced by short-term exposure is commonly referred to as acute toxicity. None of the above options are correct for this statement. The branch of toxicology that seeks results and information that can be used to assess risk to humans and other living organisms is commonly referred to as descriptive toxicology.
