What is the primary effect of halogens on human health?

Halogens, which include elements like chlorine, fluorine, bromine, and iodine, primarily affect human health by acting as irritants. When halogens are inhaled or come into contact with skin or mucous membranes, they can provoke immediate inflammatory responses. This is due to their strong oxidative properties, which can lead to irritation and damage to tissues. For example, chlorine gas, a common halogen, can irritate the respiratory system, causing coughing, choking, and other symptoms of respiratory distress. Similarly, skin exposure to halogens can result in chemical burns or irritation.

Understanding the irritant nature of halogens is critical in workplace environments where these substances might be present. Proper safety protocols, including protective equipment and ventilation, can help mitigate their harmful effects by reducing exposure and preventing irritation.
