Abstract

Environmental impact of waste tires as gound-reinforcing material is studied. Analysis for chemical compounds and toxic effect were performed on effluents from twelve lysimeters in which waste tires were mixed with sand and three initially different environmental solutions of acidic, neutral, and basic circulated through the mixture. The test results of effluents collected from the lysimeters provided that the contaminant concentrations were lower than those of Korean drinking water standards for all the selected and tested metal elements. While iron concentration increased slightly with the exposure period, other metal concentrations decreased with the number of circulation times. From the comparison with previous investigations, the contaminant concentration decreased with the increase of tire size, i.e. increases with the increase of the exposed surface of tire metals. From the toxicity tests, no deteriorative effect was observed and it could be concluded that waste tires are not biologically hostile materials.

본 연구에서는 지반 보강재로 폐타이어를 사용함에 있어서 환경적인 영향에 대하여 고찰하였다. 시험은 12개의 침출수 발생장치 속에 모래와 타이어조각들을 섞은 후 세 가지 조건의 용액을 각각 순환시킨 침출수에 대하여 화학적분석과 생물학적 독성영향을 조사하였다. 연구결과, 검출된 모든 금속원소의 오염농도는 우리나라 먹는물 수질기준치보다 훨씬 낮았고, 철을 제외한 모든 금속원소의 농도가 시간이 지남에 따라 줄어드는 것으로 나타났다. 선행된 시험과 비교한 결과 노출되는 금속의 비표면적이 클수록 즉, 타이어칩, 타이어조각, 전체타이어의 순서로 오염물질의 농도가 크게 검출되었다. 형광성 박테리아를 이용한 독성검사의 결과에서는 독성이 발견되는 경향을 보이지 않아 폐타이어에서 나오는 침출수가 유기체에 유해한 영향을 미치지 않는 것으로 나타났다.
