Recently, environmental pollution by formaldehyde has become a serious problem. Lower aldehydes may be present in the atmosphere of some industrial communities in higher concentrations than sulfer dioxide in Los Angeles and Cincinnati. Relatively high aldehyde levels have been found in the industrial section of Windsor, Ontario. Formaldehyde is irritating to the eyes of some persons in concentrations as low as about 0.25 ppm, although several ppm are required to affect the majority of persons exposed. Since few detailed reports have been made as to the assay of this substance in rain water, we investigated this and compared levels of this compound in rain water collected from three different locations in Kobe, Japan. The assayed values were compared to each other.
