분무형 생활화학제품의 분사형태 분류제안과 부유비율 평가 = Classification Proposals for Spray Type and Airborne Fraction Ratio of Consumer Chemical Products

다국어 초록 (Multilingual Abstract)

Background: The National Institute of Environmental Research (NIER)’s classification of and airborne
fraction ratio for consumer chemical products (CCP) does not reflect the characteristics of various product
classifications.
Objectives: The purpose of this study was to reclassify the types of spray products according to the diverse
spray characteristics of CCPs to evaluate the airborne fraction ratio of representative spray types and to
compare them with previous CCPs types and airborne fraction ratios.
Methods: One thousand seven hundred two products were selected through market research, and 932 newly
reported products were selected. After that, 200 were selected to evaluate products with potential inhalation
exposure. After classifying six product types that are expected to show differences in the airborne fraction
ratio according to the type of product, a final 38 products were selected for use in the airborne fraction ratio
through random sampling.
Results: CCP has been reclassified from two to six types so that the characteristics of all products are wellreflected.
The NIER simply had two airborne fraction ratios, but the results of experiments with six types
of products showed a significant difference in values (p<0.01). Airborne fraction ratios of propellant general
foam, pump general aerosol, and pump trigger foam in spray type, which were not previously present in
NIER, were 7.1%, 24.4%, and 3.5%, respectively.
Conclusions: For the diversified types of CCPs, the newly proposed classification was more appropriate than
the existing NIER classification. The airborne fraction ratio was also different for each type, so a new value
was suggested.
