【Abstract】 By using a recombinant yeast gene report system, a simple and quick assay of detecting the existence of dioxins was established. It was proved that this protocol could detect dioxins contaminations at ng level. Using this system, the industrial and domestic sewerage waters, as well as tap water in Guangzhou were sampled and detected. The results showed that the sewerage waters were polluted with dioxins in different extents, while the tap waters remained clean. The detection of dioxins in mouse serum samples from acute toxic experiment proved that this system could also be used in complicated samples assay and it has certain advantage over traditional chemical analysis protocols.
