Kontaktimyrkkyjä

Kontaktimyrkkyjä, known in English as contact poisons, are substances that are toxic when they come into direct contact with the skin, eyes, or mucous membranes. Unlike ingested or inhaled poisons, contact poisons act locally at the site of application, although some can be absorbed through the skin and cause systemic effects.

The effects of contact poisons can range from mild irritation and redness to severe chemical burns, blistering, and tissue damage. The severity of the reaction depends on the specific chemical, its concentration, the duration of exposure, and the sensitivity of the individual. Some contact poisons can also cause allergic reactions, known as contact dermatitis, which can manifest as itching, rash, and swelling.

Many household products, such as cleaning agents, solvents, and certain pesticides, can act as contact poisons if handled improperly. In industrial settings, workers may be exposed to a wider range of hazardous chemicals that pose contact poison risks. Personal protective equipment, such as gloves, eye protection, and protective clothing, is essential when handling substances that are known contact poisons. Prompt and thorough washing of affected areas with water is typically the first aid measure for contact poison exposure. Medical attention may be necessary for severe reactions or if symptoms persist.
