“…It is considered an important tool by many researchers because of its wide distribution, low maintenance cost, and ease of propagation and cultivation [21][22][23][24][25]. Due to the simplicity of the method and the high sensitivity of the plant to genotoxic agents [26][27][28][29], this species was adopted for the present study.…”

The present study aims to relate the micronucleus frequency in Tradescantia pallida to environmental factors and cardiorespiratory diseases to infer the effect of air pollution. The number of hospitalizations, diseases cases, frequency of micronuclei in plants, environmental variables, altitude, and vehicle traffic in cities of Mato Grosso do Sul were evaluated due to the high flow that surrounds agribusiness. The frequency of micronuclei decreased with the increase in relative humidity, while the altitude did not influence the mutagenicity or genotoxicity of the evaluated plants. The municipalities with micronucleus frequencies above 200 had the highest number of vehicle and cardiorespiratory diseases. Biomonitoring data obtained in cities throughout the year indicate that the number of cardiorespiratory diseases was probably due to vehicular pollution, which is evidenced by the increased frequency of micronuclei in T. pallida.

“…In general, their urban landscapes are highly complex and the evaluation of the effect of air pollution on health outcomes must consider their inherent heterogeneity. Biomonitoring methods based on tree barks have been considered as an alternative and/or as a complement to field measurements (Falla et al, 2000) and to satellite image data (Van Donkelaar et al, 2016), which are highly cost restrictive specially for developing countries (Molina et al, 2004). We evaluate the role of tree species in low cost passive biomonitoring techniques designed to provide a higher spatial resolution of exposure to chemical elements composition required by environmental epidemiology (Pope et al, 2009;Bravo et al, 2015).…”

“…Our results point toward the importance of the choice of the appropriate species for biomonitoring studies based on tree barks. The biodiversity available in an urban environment like the one in São Paulo adds a complication to the problem of choosing the most appropriate species for this type of study (Falla et al, 2000). This choice must be based on the combination of spatial coverage and ability to distinguish between different levels of local air pollution.…”

“…As an alternative, biomonitoring methods are already used in many countries (Falla et al, 2000) to address variability of air pollution in large geographical areas (e.g., Kuik and Wolterbeek, 1994;Böhm et al, 1998). Tree barks have been recently used to evaluate a fine spatial distribution of chemical elements concentration (Guéguen et al, 2012;Ejidike and Onianwa, 2015), which increases with the levels of traffic intensity (Moreira et al, 2016).…”

The analysis of chemical elements in the barks of trees is an alternative procedure to access spatial heterogeneity of traffic related air pollution. However, the role of tree species in the characterization of the variability of airborne pollution is poorly known. We present an observational study conducted in São Paulo, Brazil, based on the analysis of 498 trees from three common species: Tipuana tipu, Poincianella pluviosa, and Ligustrum sp.. We considered ANCOVA models to compare the concentrations of Al, Fe, Zn, Cu, Mn, Ba, and S in the bark (periderm) of trees located close to streets with different levels of traffic intensity controlling for the extension of nearby green areas. The expected trend of increasing elemental concentration in the bark of trees located near streets with greater traffic intensity or close to smaller green areas was only fully evidenced by T. tipu. For instance, the concentrations of Zn, Fe, Al, and Ba increase by 200, 350, 230, and 280% respectively, for trees of this species located near arterial streets when compared to those observed near local streets. On the other hand, the concentrations of Zn, Fe, Al, and Ba are reduced by 41, 45, 50, and 30%, respectively, for trees located near green areas. For P. pluviosa, the capacity to suggest an association between the tree bark concentration of chemical elements with increasing levels of air pollution and presence of green areas was only fully observed for Zn and Cu. For Ligustrum sp., weaker and sometimes non-expected associations between bark concentrations of the chemical elements and either street classification or green area extension were observed. Our results indicate that the choice of species is a key element in the use of tree barks as a biomonitoring tool in urban landscapes. Species like T. tipu, with rough and highly porous bark, are the most appropriate for such purpose.

“…In comparison with the traditional monitoring systems, the use of biosensors has the advantage to show us the real impact of pollutants on living organisms, thus providing additional data to the electronic instruments. Moreover, this allows to take into account the concepts of bioavailability, dose and exposure, resulting in a more realistic approach of the impact of pollutants on environmental and human health [13]. Plants are more sensitive than humans and animals in terms of physiological reaction to fluctuations of multiple parameters [14], making them suitable tools for environmental monitoring.…”

Abstract-This paper describes an innovative monitoring technology for detecting ground-level ozone pollution, b ased on the deployment of a network of wireless devices connected to a collection of plants, used as bio-sensors. Such devices retrieve and transmit the electrical activity signals experienced in plants, used to monitor environmental conditions. The distributed plants as sensors infrastructure communicates wirelessly with a weather station, equipped with meteorological sensors as well as data logging and both wireless and wired communication capabilities. A back end server collects and analyze real-time data from the station and delivers environmental and ozone pollution information to users through a web portal. In order to perform a classification on the level of ozone exposure, a correlation-based approach has been used. The system is implemented in pilot phase with a sensing infrastructure of four plants and started operation in November 2014. As the data collection volume increases, more accurate classification techniques can be performed.
