Application Summary AI generated

This standard provides a technical methodology for calculating the required health protection distance between industrial emission sources and residential areas to prevent harm from fugitive (non-ducted) atmospheric pollutants. It is applied in environmental impact assessments, urban planning, and factory siting for industries such as chemical manufacturing, smelting, and waste treatment in China. The guideline ensures that buffer zones are scientifically determined based on local meteorological conditions, emission rates, and toxicity of released substances.
