Since most people spend a large majority of their time indoors (at least in the industrialized countries), indoor air may affect human health more than outdoor air. This study was carried out to characterize the reference and equivalent methods against the low volume method which was promulgated by the Ministry of Health and Social Affairs. The Laser and Piezo air sampler offer the advantage of real time data and low labor costs. The arithmetic mean concentrations were found to be 102.9% (Laser-2 min method) and 65.9% (Piezo method) against low volume method (100%). The statistical analysis procedure for this comparision is linear regression. The linear regression line of low volume method had slopes of 0.5487 and 0.9697 and Y intercepts of 0.0266 and 0.0110 $\mu$g/m$^3$ about Laser (2 min) and (24 h) method respectively. And the correlation coefficients were 0.7271 and 0.9433.

Branch rivers of Han-river contribute significantly to the pollution and eutrophication that have caused drastic changes to the ecosystem of Han-river. In Tanchun, two sewage treatment plants have been operated and their drain water have significantly affected Tanchun water quality. Here we investigate on the pollution change of Tanchun that has affected Han-river. The results were as follows : 1. Attribution to elevate water pollution concentrations of Han-river by Tanchun were T-P, BOD, T-N, COD in orders. 2. The highest loading pollutant in Han-river by Tanchun rated about 2 times by T-P. 3. In the downstream of Tanchun was low self-purification than upstream. 4. The most affected Tanchun water quality was Tanchun treatment plant in the downstream of Tanchun.

[연구배경] 서울시에서는 터널 보행로 환경개선 사업의 일환으로 2008년부터 터널 방음벽을 설치하여 현재 14개 터널에 설치 완료하였다. 방음벽은 터널 내 차도와 보행로를 차단하여 보행로에서의 차량 소음을 저감시킬 목적으로 설치되지만 차량 통행으로 인한 대기오염을 차단하는 효과도 가져올 것이다. 이에 따라 보행로에서의 대기질 개선효과를 조사할 필요성이 제기되어 연구가 시행된 경우도 있었으나, 차도와 보행로에서 동시에 측정하여 보행로에서의 대기질 개선효과를 연구한 경우는 드물었다. [연구목적] 본 연구의 목적은 터널 방음벽이 설치된 터널 보행로에 대해 방음벽 설치에 따른 대기 중 PM10, PM2.5 개선효과를 조사하기 위함이다. [연구방법] 방음벽이 설치된 K터널을 대상으로 터널 내부 중간 지점에서 광산란 측정방식의 연속먼지 측정기기를 차도와 보행로에 동시에 설치하였다. 조사 기간은 2011년 3월 3일~8일까지 실시간 측정하였으며 측정 자료는 매 1분마다 산출하였고 측정항목은 PM10, PM2.5이다. [연구결과] 측정기간 중 차도와 보행로의 동시 유효 자료수는 7398개이며 측정 결과 PM10은 차도(53±24)㎍/m3, 보행로(36±18)㎍/m3로 보행로에서의 감소율은 32%였다. 또한 PM2.5는 차도(35±17)㎍/m3, 보행로(27±13)㎍/m3로 보행로에서의 감소율은 23%로 나타났다. 보행로에서의 이 정도 감소율이 어느 정도 타당한 것인지 알아보기 위해 1.5 km 떨어진 일반대기 측정소 자료와 비교하였다. 그 결과 보행로의 PM10은 인근의 일반대기 PM10 평균보다 7㎍/m3 낮게 나타나 방음벽에 의한 개선효과가 뚜렷하다고 할 수 있으며 보행로의 PM2.5는 일반대기 PM2.5보다 6㎍/m3 높게 나타나 터널 차도보다는 감소하였으나 일반 대기 수준까지는 개선되지 않은 것으로 나타났다.

The water quality simulation was carried out to predict water quality in Tan stream of the Han river using water quality model, QUAL2E. In the end, the future variations in water quality of Tan stream were simulated and the prediction of the impacts of Tan stream on water quality in the Han river was carried out by applying the Tan stream simulation results into the model. The results are as follows. The predicted results of future water quality of Tan stream suggested that the concentrations of BOD, T-N and T-P at Chungdam bridge would increase to 0.68~0.77 mg/$\ell$, 1.33~1.62 mg/$\ell$ and 0.05~0.06 mg/$\ell$, respectively in 2006 and 2011 and that with the implementation of advanced treatment in Sungnam and Tanchun sewage treatment plants, the concentration of T-N would be reduced more as the amount of treated sewage increase, while the concentration of T-P would stay 0.49 mg/$\ell$. The results obtained from simulation of the impacts of future Tan stream water quality improvement on the main stream of the Han river showed that with implementation of advanced treatment in both Sungnam and Tanchun sewage treatment plants, the concentration of T-N, T-P and chlorophyll-a at Hangang bridge and Heangju bridge would be reduced by 11.6%, 7.7% and 20.9%, respectively in 2..6 and by 13.6%, 9.4% and 22.2%, respectively in 2011, which indicates that the effect on the reduction of T-N and T-P would be relatively significant while the effect on the decrease of algae would be slight.
