Study on the genotoxicity of soi1 leachate from two polluted sites in Cheongju with Tradescantia-micronuclus assay

자주달개비 미세핵 분석법을 이용한 청주공단주변 토양침출수의 유전독성 평가

Soil contaminants are common in industrialized sites, They can affect directly soil and indirectly ground water and food. Soil mutagens and carcinogens are of great interest due to their potentially hazardous effects on human health. The aim of this study was to monitor the genotoxicity of contaminated soils, Soil leachates were collected from two polluted sites and one control site in Cheongju. Tradescantia BNL 4430 clone was used as experimental matierials. Chromosomal damages induced by soil leachates were detected by the Tradescantia-micronucleus assay. It is known from the result that Tradescantia-micronucleus assay is an excellent botanical tool for detection of biological risk due to environmental toxicants.
