“…When we correlated the values of PM 2.5 during the entire period with the %MCN of active exposure, we observed a positive and extremely significant correlation ( r = 0.818 p = 0.004), corroborating the results obtained by Batalha et al [46], Carvalho-Oliveira et al [29], Carreras et al [43] and Prajapati & Tripathi [47]. All these results show the importance of this biomarker in the evaluating genotoxic damage caused by exposure to particulate matter generated by burning biomass.…”

BackgroundThe Brazilian Amazon has suffered impacts from non-sustainable economic development, especially owing to the expansion of agricultural commodities into forest areas. The Tangará da Serra region, located in the southern of the Legal Amazon, is characterized by non-mechanized sugar cane production. In addition, it lies on the dispersion path of the pollution plume generated by biomass burning. The aim of this study was to assess the genotoxic potential of the atmosphere in the Tangará da Serra region, using Tradescantia pallida as in situ bioindicator.MethodsThe study was conducted during the dry and rainy seasons, where the plants were exposed to two types of exposure, active and passive.ResultsThe results showed that in all the sampling seasons, irrespective of exposure type, there was an increase in micronucleus frequency, compared to control and that it was statistically significant in the dry season. A strong and significant relationship was also observed between the increase in micronucleus incidence and the rise in fine particulate matter, and hospital morbidity from respiratory diseases in children.ConclusionsBased on the results, we demonstrated that pollutants generated by biomass burning in the Brazilian Amazon can induce genetic damage in test plants that was more prominent during dry season, and correlated with the level of particulates and elevated respiratory morbidity.

“…The data cited by Carreras et al (2006) from a study with the same focus, using 3 test points in the city of Cordoba, Argentina, showed values between 2.4 ± 2.08 in distant area from the center and 4.2 ± 2.6 in region central city, revealing lower rates in inducing genetic damage in T. pallida compared with our study. The results showed mean values of 5.6 ± 0.7 and 7.1 ± 1.0, equating to the average percentage of this study, since the highest percentage found in sections that had only the pollutant factor of vehicle exhaust it was 7.5 ± 2.27, as shown in Table 1.…”

“…The frequency of MN found at points with higher vehicular traffic is according to records of Carreras et al (2006) and Klumpp et al (2006) who observed a direct relationship between mutagenic index and expressively increase of population concentration in urban areas. Metropolitan areas tend to present more atmospheres contaminated by pollutants than areas with less flow of vehicles and people, leading to a higher incidence of genetic damage in plants used as bio-indicators.…”

Air pollutants affect their quality, making, inappropriate, harmful and damaging to health in general. The air quality can be measured by the use of higher plants as bioindicators in environmental biomonitoring. In this study, we evaluated the increased frequency of micronuclei (MN) in Tradescantia pallida exposed to potentially toxic environments. The vegetables were implanted in five points (4 test and 1 control) for 15, 30 and 60 days. After this period of exposure, the young inflorescences were analyzed and the observation frequency of MN using the technique of Tradescantia-micronucleus (TRAD-MCN). The results showed an increased frequency of MN in pollen grains of T. pallida in environment with severe vehicular exhaust and manipulation of benzene derivatives, indicating that the compounds present in the atmosphere of these environments have genotoxic potential.

“…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).…”
