We investigated the water quality of rainwater in urban areas to determine its
potential as drinking water, living water, or re-use water, and investigated the
connection between rainwater and atmospheric environmental conditions such as fine
dust, yellow dust, nitrous oxide, and sulfur oxides. Twenty-five to thirty-eight rainwater
quality characteristics were analyzed in Seoul, including ion substances, heavy metals,
general bacteria, pH, color, turbidity, and ammonia nitrogen. Analyse is of the
characteristics of first rainwater from four-story building rooftops, such as ionic
materials, heavy metals, and general bacteria. and of the six-point rainwater from the
acid rain measuring network were conducted. Analysis of the correlation between the
initial rainwater and the atmospheric environmental factors showed that the level of
pollution in atmospheric environmental conditions increased with the longer the
antecedent rainless hours. In addition, Pearson correlation analysi
