Chlorine gas is used widely by industry and as a disinfectant and bleach, and, due to its toxicity and ease of procurement, has been used as a chemical warfare agent. Chlorine is a strong oxidizer that hydrolyzes in water to form hydrochloric and hypochlorous acid. Upon chlorine inhalation, the respiratory tract is the predominant target organ in humans and animals as chlorine is a contact irritant. Exposure causes sensory irritation and pulmonary dysfunction, and at sufficiently high concentrations results in lung lesions and injury to other internal organs including the heart. Human and animal studies have shown that chlorine toxicity is influenced more by exposure concentration than duration, is gender-independent, and increases with age, cigarette smoking, and preexisting respiratory conditions such as asthma and airway hyperreactivity. Treatment is largely supportive, although animal studies are examining the utility of various compounds for chlorine-specific treatment based on its mechanism of action.
