Can exposure to inhaled ammonia cause long-term neurological damage? This study investigates the potential *neurotoxic* effects of inhaled ammonia following a large ammonia release that affected nearby residents. This incident provides a unique opportunity to study a range of potential toxic events. Six weeks after the event, symptomatic individuals underwent questionnaires, physical examinations, and neurobehavioral testing. Compared to unexposed subjects, the exposed group exhibited significantly abnormal results in simple and choice reaction time, balance, color discrimination, visual field performance, and hearing. Cognitive performance was also impaired. These findings suggest that even brief exposure to inhaled ammonia can be associated with persistent *neurobehavioral impairment*. The authors conclude that inhaled ammonia shares the *toxicity* of endogenous ammonia, potentially causing permanent neurological effects. This has important implications for safety regulations and risk management in industrial settings.
Published in Environmental Management and Health, this study aligns with the journal's focus on understanding and mitigating environmental health risks. By investigating the neurotoxic effects of inhaled ammonia, the research provides valuable insights for protecting public health and safety in industrial settings.
