The World Health Organization (WHO) and its member states strive to ensure universal access to safe drinking water regardless of developmental or socioeconomic status. WHO is tasked with proposing regulations and recommendations concerning global health issues. Hydrogen sulfide, a colorless gas with a rotten egg odor, is detectable at low concentrations and occurs naturally in various environments including crude petroleum, natural gas, and volcanic gases. Industrial processes and bacterial decomposition also contribute to its presence. Hydrogen sulfide is utilized in sulfur production and can be released into the air, water, and soil, persisting in the atmosphere for up to 42 days. Exposure can occur near industrial facilities or agricultural sites with manure storage. Workers in certain industries are particularly at risk. Human studies indicate respiratory and nervous systems are most vulnerable to hydrogen sulfide toxicity, with symptoms ranging from irritation at low concentrations to respiratory distress or loss of consciousness at high concentrations. Long-term effects may include cognitive and motor impairments. Therefore, mitigating exposure to hydrogen sulfide is crucial for public health. [ABSTRACT FROM AUTHOR]
