Abstract ▼ AI-Helper

The characteristics of $PM_{10}$, $PM_{2.5}$ and Ratio($PM_{2.5}/PM_{10}$) of 11 urban air monitoring stations in Gyeongnam were analyzed for the last 3 years('15~'17). The average of the all stations was $PM_{10}\;45{\mu}g/m^3$, $PM_{2.5}\;24{\mu}g/m^3$ and Ratio 0.54, and annual reduction rates were $PM_{10}-2.9%$, $PM_{2.5}-2.7%$ and Ratio -1.2%, respectively. The seasonal characteristics of $PM_{10}$ were spring $54{\mu}g/m^3$ > winter $48{\mu}g/m^3$ > summer/autumn $40{\mu}g/m^3$, $PM_{2.5}$ were spring/winter $26{\mu}g/m^3$ > summer 23 > autumn $22{\mu}g/m^3$ and Ratio were summer 0.56 > winter 0.55 > autumn 0.54 > spring 0.51, respectively. The hourly characteristics of $PM_{10}$ were $11{\mu}g/m^3$ higher than 09:00~12:00 at 03:00~06:00, $PM_{2.5}$ were $6{\mu}g/m^3$ higher than 09:00~12:00 at 17:00~18:00 and Ratio were 0.07 higher than 04:00~06:00 at 19:00. By site, the highest concentration of $PM_{10}$ was YJ site $53{\mu}g/m^3$ and $PM_{2.5}$ was HW site $28{\mu}g/m^3$. And Ratio at HD site showed the largest reduction from '15 0.62 to '17 0.52.

제안 방법

In this paper, at 11 air pollution monitoring stations where the PM_2.5is measuring in Gyeongnam area were collected PM₁₀ and PM_2.5 data for the last three years(`15~`17), and the temporal and spatial characteristics including the PM_2.5/PM₁₀ concentration ratio(Ratio) were analyzed.

대상 데이터

For PM reduction plans in Gyeongnam, PM₁₀and PM_2.5 data in 11 air monitoring stations for the past 3 years(`15~`17) were collected and analyzed. The results of the analysis are as follows.
In this study, PM₁₀ and PM_2.5data collected 26,304 final confirmed hourly concentration for the last 3 years(`15~`17) in 11 urban stations on Air Korea homepage(Air Korea, 2018). As shown in Table 1, the average 93% effective measurement data excluding the error data was used in this study.
In this study, PM₁₀ and PM_2.5 data from the 11 urban stations were used. The eight sites such as the HW site(Hoewong-dong, Changwo) are located in the residential area, the GJ site(Gaeumjeong-dong, Changwo) and SD site(Sangdae-dong, Jinju) in the industrial area, and the HD site(Hadong-eup, Hadong) in the green area(KNHE, 2018).
