“…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).…”

Genotoxic effects of extremely low frequency (ELF) magnetic fields (MF) evaluated by theTradescantia-micronucleus assay

Extremely low frequency (ELF) electric fields (EF) and magnetic fields (MF) are generated during the production, transmission, and use of electrical energy. Although epidemiology studies suggest that there is a cancer risk associated with exposure to ELF-MF, short-term genotoxicity assays with bacteria and mammalian cells have produced inconsistent results. In the present study, we investigated the possible genotoxicity of ELF-MF by using the Tradescantia-micronucleus (Trad-MN) assay, a sensitive, reproducible, well-standardized assay for genotoxicity testing. A 50 Hz ELF-MF was generated by a laboratory exposure system consisting of a pair of parallel coils in a Helmholtz configuration. Exposure of Tradescantia (clone # 4430) inflorescences to the ELF-MF, at a flux density (B) corresponding to 1 mT, for 1, 6, and 24 h resulted in a time-dependent increase in MN frequency. The results indicate that a 50 Hz MF of 1 mT field strength is genotoxic in the Trad-MN bioassay and suggest that this assay may be suitable as a biomonitor for detecting the genotoxicity of ELF-MF in the field.

“…Radon has low solubility in water (ICRP 2014) which is temperature dependent, and it decreases at higher temperatures (Battino 1979). Radon is trapped by plant organs by diffusion, adsorption, and permeation (Tavera et al 2002;Vives et al 2011).…”

Wastewater samples were collected from Al-Rustumia wastewater treatment plant. The methodology which was used to measure radon activity levels was long-term air measurements with passive solid-state alpha track detector CR-39. The collected samples include wastewater before and after treatment for 5 months which started from September 2017 to January 2018. The results show that the average values of radon activity level for untreated and treated wastewater samples were 0.049 Bq L −1 and 0.036 Bq L −1 , respectively. Dissolved radon concentrations for the study samples were also calculated and their values were 1.270 Bq L −1 and 0.937 Bq L −1 , respectively. The calculated radon surface exhalation rate for wastewater samples before treatment was 0.048 Bq m −2 h −1 and after treatment was 0.035 Bq m −2 h −1. These values are lower than the maximum acceptable radon levels as given by United States Environmental Protection Agency. As well as, the results reveal that radon activity level decreases after treatment process implementation, and there are no considerable variations with different times of the year.
