“…Reports indicate that the Trad-MN assay is an efficient tool for monitoring various genotoxic chemical pollutants in urban air (Monarca et al, 1999;Cape, 2003), soil and aqueous media (Gill and Sandhu, 1992), drinking water (Monarca et al, 1998a), surface and waste water (Ruiz et al, 1992;Monarca et al, 2000;Monarca et al, 2003), and in work and indoor environments (Monarca et al, 1998b;Monarca et al, 2001;Kim et al, 2003). The Trad-MN assay has also been used for testing the genotoxicity of physical agents, such as radon (Villalobos-Petrini et al, 1999;Tavera et al, 2002), radionuclides (Marciulioniene et al, 2002), and UV-B and radiofrequency radiation (Haider et al, 1994;Wang and Wang, 1999).…”
