영문 초록

Objectives: The study evaluated correlations among monthly PM₂.₅, PM₁₀, Cd, Pb concentrations and the number of Asian dust days. Methods: Based on data from ‘The annual report on air quality in Korea from 1999 to 2017’, concentrations of PM₁₀, PM₂.₅, Cd, Pb, and the number of Asian dust days were recalculated to mean, standard deviation, minimum, and maximum. Correlation coefficients were calculated among PM₂.₅, PM₁₀, Cd, Pb, and Asian dust days. Results: Asian dust days were correlated only with PM₁₀ among the four factors of PM₁₀, PM₂.₅, Cd, and Pb. The four factors of PM₁₀, PM₂.₅, Cd, and Pb were very significantly correlated with each other (p<0.01). Their correlation coefficients for PM₁₀ were 0.800 for PM₂.₅, 0.823 for Cd, and 0.892 for Pb. PM₂.₅ was also correlated strongly with Cd (0.845) and Pb (0.830). Cd had a correlation with Pb of 0.971. The maximums of PM₂.₅, PM₁₀, and Pb were shown to exceed the atmospheric environmental standard of Korea, which necessitates national continuous exposure control. Based on exposure data, Asian dust days were thought to be an exposure factor for Cd and Pb. Conclusion: Asian dust might be a factor in Cd and Pb exposure. National exposure controls are required for exposure to PM₂.₅, PM₁₀, Cd, and Pb.
