Final answer:
Children might come into contact with poisonous substances through household products, environmental pollutants, and certain animals.
Step-by-step explanation:
Poisonous items or substances that children might come into contact with include a range of household products, environmental pollutants, and certain animals. These can include corrosive chemicals such as strong acids or bases, which can damage living tissues upon contact. Metabolic poisons like carbon monoxide disrupt bodily functions. Children are especially at risk of exposure to lead, which is present in deteriorating paints and can lead to poisoning through ingestion of contaminated dust. Other substances such as cadmium are carcinogenic, and mercury can have detrimental effects on the nervous system.
In the environment, wastes including old batteries, pesticides, and car oil are reactive and can be harmful when absorbed. Even in a learning environment such as a science laboratory, it is crucial to avoid eating or drinking, as tables and equipment may be contaminated with toxic substances. Simple measures like cleaning materials thoroughly and handling heat sources carefully can prevent accidents and exposure to harmful chemicals.
Skin or eye contact with chemicals can cause damage or allow toxins to be absorbed into the bloodstream, making proper safety precautions critical to avoid serious health risks.
