“…At intersections with traffic lights and signals, drivers tend to decrease their speed, stopping, and then continuing with sudden acceleration, and it is possible to infer that the gradual emission of exhaust gases, from the engine and combustion with a high concentration of toxic elements, especially carbon monoxide (CO), particulate matter (PM), hydrocarbons (PAHs), nitrogen oxide (NO), and sulfur (SO₂), lead to mutations in the somatic and germ cells of T. pallida and favor the incidence of MCN [29,33,35,56,57].…”

Air pollution substantially damages ecosystems and public health and is one of the major challenges for air quality monitoring management. The use of the plant bioindicator Tradescantia pallida (Rose) D. R. Hunt has shown excellent results in terms of determining the effect of airborne contaminants in urban environments, complementing conventional methods. The present study seeks to determine the air quality in the Ivinhema Valley, MS, using the variation in MCN frequency and stomatal indices of T. pallida as air pollution biomarkers. The biomonitoring tests were performed monthly by collecting floral and leaf buds during the summer, autumn, winter, and spring of 2021 in Angélica, Ivinhema, and Nova Andradina. The stomatal leaf density, influence of vehicle flow, and environmental variables such as altitude, temperature (°C), relative humidity (RH), and rainfall in the three cities under study with different urban vehicle intensities were analyzed. A significant increase in MCN was observed for the cities of Nova Andradina and Ivinhema in summer and spring. On the other hand, the city of Angélica had a low frequency of MCN throughout the experimental period. A seasonal and spatial pattern was also observed for the stomatal index, with significantly higher values for the city of Angélica in autumn and winter. Our data allowed observing that the MCN showed the greatest association with vehicular flow. The mutagenic effects observed in T. pallida, through the MCN frequency, constituted an important biomarker of air pollution, explained mainly by the relationship with the flow of vehicles.

“…Tradescantia pallida (Rose) D. R. Hunt var. purpurea Boom, popularmente conhecida como coração-roxo, comumente utilizada como planta ornamental em praças e jardins, é utilizada para o biomonitoramento da qualidade do ar atmosférico por meio da quantificação dos micronúcleos resultantes de quebras ou perdas cromossômicas (Cassanego et al, 2015;Costa et al, 2016;Carvalho et al, 2017;Rocha et al, 2018).…”

A genotoxicidade do ar e a composição e estrutura comunitária de epífitos vasculares foram analisadas em um fragmento de mata ciliar inserido em uma unidade de conservação localizada na região metropolitana de Porto Alegre, no sul do Brasil. Durante cinco eventos distribuídos ao longo de um ano, inflorescências de Tradescantia pallida var. purpurea foram expostas por 8 horas ao ar atmosférico na borda do fragmento e micronúcleos foram quantificados em células meióticas. Foram registradas frequências de 4,07 a 5,27 micronúcleos, caracterizando o ambiente como genotóxico. Foram inventariadas 35 espécies de epífitos vasculares, alocadas em 22 gêneros e seis famílias. Orchidaceae, Bromeliaceae, Polypodiaceae e Cactaceae foram as famílias com maior riqueza (12, nove, seis e cinco espécies, respectivamente). Microgramma vacciniifolia, Rhipsalis teres, Tillandsia aeranthos e Pleopeltis pleopeltifolia, espécies com características adaptativas a ambientes com intervenções antrópicas, concentraram mais de 50% do valor de importância epifítico total da comunidade. A riqueza de espécies foi menor quando comparada às de matas ciliares do trecho superior da bacia hidrográfica em que se encontra a unidade de conservação. A simplificação da estrutura da comunidade epifítica pode estar associada ao aumento da urbanização e da poluição atmosférica evidenciada pela genotoxicidade do ar. Atmospheric Air Genotoxicity and Vascular Epiphytes in a Conservation Unit from a Metropolitan Area in South Brazil ABSTRACTThe genotoxicity of the atmospheric air and the community structure of vascular epiphytes were analyzed in a riparian forest fragment inserted in a conservation unit located in the metropolitan area of Porto Alegre, South Brazil. During five events along a year, inflorescences of Tradescantia pallida var. purpurea were exposed for 8 hours to the atmospheric air at the edge of the fragment and micronuclei were quantified in meiotic cells. Frequencies from 4.07 to 5.27 micronuclei were recorded, characterizing the environment as genotoxic. Thirty-five species of vascular epiphytes were inventoried, allocated in 22 genera and six families. Orchidaceae, Bromeliaceae, Polypodiaceae and Cactaceae were the families with the greatest richness (12, nine, six and five species, respectively). Microgramma vacciniifolia, Rhipsalis teres, Tillandsia aeranthos and Pleopeltis pleopeltifolia, species with adaptive characteristics to environments with anthropic interventions, concentrated more than 50% of the total epiphytic importance value of the community. Species richness was lower when compared to riparian forests at the upper stretch of the hydrographic basin where the conservation unit is located. The simplification of the structure of the epiphytic community may be associated with the increase in urbanization and atmospheric pollution evidenced by the genotoxicity of the air.Keywords: conservation, floristics, forest fragmentation, genotoxic potential, urbanization.
