Biomonitoring genotoxic risks under the urban weather conditions and polluted atmosphere in Santo André, SP, Brazil, through Trad-MCN bioassay

Cashew nut roasting: Chemical characterization of particulate matter and genotocixity analysis

“…The influence of weather conditions such as relative humidity, temperature and rainfall on the Trad-MCN assay as a result of exposure to genotoxic agents has been investigated by a number of studies (Klumpp et al, 2004;Savóia et al, 2009;Sisenando et al, 2011;Pereira et al, 2013). Corroborating Savóia et al (2009) and Sisenando et al (2011), we also observed an inverse relationship between the rate of MN and rainfall (Table 3).…”

“…An appropriate alternative to the environmental conditions found in tropical countries is the use of Tradescantia pallida. Several studies have demonstrated its sensitivity to the genotoxic compounds from air pollutants in situ (Batalha et al, 1999;Guimarães et al, 2000;Carreras et al, 2006;Prajapati and Tripathi, 2008;Mariani et al, 2009;Meireles et al, 2009;Savóia et al, 2009;Sisenando et al, 2011;Pereira et al, 2013) and ex situ (Carvalho-Oliveira et al, 2005;Alves et al, 2011Alves et al, , 2014Carreras et al, 2013).…”

Biomonitoring the genotoxic potential of the air on Tradescantia pallida var. purpurea under climatic conditions in the Sinos River basin, Rio Grande do Sul, Brazil

“…Atmospheric air pollution is primarily the result of emissions of gases and particulate material, causing negative effects on living organisms and the environment (Savóia et al, 2009;Teixeira et al, 2012). Among air pollutants, mobile sources comprising motorized vehicle traffic, and stationary sources which include industries, are noteworthy.…”

“…Despite this, the majority of risk assessment studies of atmospheric pollutants are based on concentrations detected by chemical analyses for simple substances and the synergic and genotoxic effects of complex mixtures of these compounds are still poorly known (Savóia et al, 2009;Merlo et al, 2011). Over recent years, studies have begun to integrate biological indicators with physical and chemical parameters, with the goal of identifying genetic changes that may occur in organisms as a result of the environmental conditions in which they live or after exposure as active indicators in environments that are supposedly polluted (Meireles et al, 2009;Savóia et al, 2009;Carreras et al, 2013;Pereira et al, 2013).…”

“…The influence of the combination of climatic factors with atmospheric pollutants on the response of T. pallida var. purpurea has been investigated, warning of the possible interference of certain weather conditions in micronuclei formation (Meireles et al, 2009;Savóia et al, 2009;Pereira et al, 2013).…”
