ABSTRACT

The paper deals with a possible use of the bacterial detection system of SOS chromotest to test mutagenicity of waste dump water checking the mutagenicity degree on real samples from Praksice waste dump, which is a controlled waste dump with mixed industrial, municipal and inert wastes. The waste dump surface water samples were taken from a no-name influent stream springing below the waste dump body between 2005 and 2009. After metabolic activation by microsomal fraction in vitro, medium to high mutagenicity was registered in all the samples. The SOS chromotest is assessed as an effective and economically acceptable method to check and determine the mutagenicity degree of contaminated water.
