Is a thermometer toxic?
Generally speaking, whether a thermometer is toxic depends on its type. If it is a mercury thermometer, the mercury inside is toxic; if it is an electronic thermometer, it is non-toxic. The details are as follows:
1. Toxic
Mercury thermometers are made of glass and contain a column of mercury that rises with body temperature. The mercury inside these thermometers is toxic. Mercury is the only metal that remains liquid at room temperature. When mercury-containing devices break, the mercury can evaporate into mercury vapor, which is easily absorbed by walls, clothing, and other materials, becoming a continuous source of air pollution. Prolonged or significant inhalation may lead to poisoning, causing symptoms such as nausea, vomiting, abdominal pain, diarrhea, fatigue, generalized body aches, restlessness, insomnia, seizures, coma, and mental disturbances.
2. Non-toxic
Electronic thermometers consist of a temperature sensor, liquid crystal display, button battery, dedicated integrated circuits, and other electronic components, none of which contain toxic substances. Electronic thermometers are safer, more environmentally friendly, and provide faster readings. As a result, they have gradually replaced mercury thermometers in modern medical practice.
If a patient experiences any discomfort, it is recommended to seek timely medical attention to avoid delays in diagnosis and treatment.
