“…According to Chinese researchers (Zhang et al 2016), among 47 investigated species collected from two heavy traffic roadside sites and one suburban site in Beijing, the plant species Magnolia denudata, Diospyros kaki, Ailanthus altissima, Fraxinus chinensis and Rosa chinensis were identified as tolerant species to an environment of heavy air pollution and were recommend to be planted at various locations in the city, especially at roadsides experiencing heavy traffic. Studies which were carried out at increasing distances of 100, 300 and 500 m around three brick kiln sites (Pakistan) showed various air pollution tolerance index (APTI) values of plant species investigated there: Calotropis procera (APTI = 20.05) and Alternanthera pungens (APTI = 17.13) were found to be the most tolerant species and Malva neglecta (APTI = 8.83) was found to be the most sensitive species (Achakzai et al 2017).…”

The aim of the study was to determine the state of the environment in Sosnowiec (southern Poland) based on the ratio of air pollution tolerance index (APTI) and the determination of concentrations of selected metals in soil and plant material. The study was conducted in ten stands: five of them were identified as 'polluted' and five as 'clean' stands. The metal content was evaluated by the atomic absorption method. For APTI calculation, analysis of total chlorophyll concentration and relative water content, the pH of the extract from the leaves was used. Analysis of the bioaccumulation of metals in the leaves revealed excessive concentrations of Pb (32.4 mg kg -1 ) and Zn (129.78 mg kg) at the KWK (coal mine) and Las (forest) stands. Higher capacity accumulation of Pb and Fe was characteristic for Plantago lanceolata. The permitted content of Pb (762.6 mg kg -1 ) in the soil samples collected at the Cedler stand was exceeded. Elevated levels, higher than the permissible concentration of Cd, were documented in soil samples from most stands within the city. In soil samples collected at the Cedler stand, Cd concentration was almost 15 times higher than acceptable for soil (4 mg kg -1 ). Based on the scope of the APTI 4.4-9.42 index obtained for the studied species, they should be considered sensitive plants. All selected species can be used as bioindicators for environmental pollution.

“…However, gaseous pollutants are very quickly metabolised unless photosynthesis and membrane permeability are damaged, which means that stomatal uptake remains high while the plant remains healthy and that pollution tolerance may therefore be considered a trait that influences gaseous pollutant removal 77 . Numerous studies have employed an Air Pollution Tolerance Index (APTI) based on leaf attributes that are associated with greater tolerance of air and water pollution stress 120,[135][136][137][138][139][140][141][142][143][144] . APTI requires the determination of four biochemical parameters at leaf level, which are then subjected to a formula (Eq.…”

“…This method has been used to estimate air pollution tolerance for different species around the world. However, such studies have predominantly involved specimens whose provenance differs in environmental conditions (climate, soil water and/or nutrient content, and ambient air pollution concentrations) from those of typical urban planting sites in the United Kingdom [134][135][136][137][138][140][141][142][143][144] . Where the above APTI method has been applied in the United Kingdom (e.g.…”

Designing vegetation barriers for urban air pollution abatement: a practical review for appropriate plant species selection

Vegetation can form a barrier between traffic emissions and adjacent areas, but the optimal configuration and plant composition of such green infrastructure (GI) are currently unclear. We examined the literature on aspects of GI that influence ambient air quality, with a particular focus on vegetation barriers in open-road environments. Findings were critically evaluated in order to identify principles for effective barrier design, and recommendations regarding plant selection were established with reference to relevant spatial scales. As an initial investigation into viable species for UK urban GI, we compiled data on 12 influential traits for 61 tree species, and created a supplementary plant selection framework. We found that if the scale of the intervention, the context and conditions of the site and the target air pollutant type are appreciated, the selection of plants that exhibit certain biophysical traits can enhance air pollution mitigation. For super-micrometre particles, advantageous leaf micromorphological traits include the presence of trichomes and ridges or grooves. Stomatal characteristics are more significant for sub-micrometre particle and gaseous pollutant uptake, although we found a comparative dearth of studies into such pollutants. Generally advantageous macromorphological traits include small leaf size and high leaf complexity, but optimal vegetation height, form and density depend on planting configuration with respect to the immediate physical environment. Biogenic volatile organic compound and pollen emissions can be minimised by appropriate species selection, although their significance varies with scale and context. While this review assembled evidence-based recommendations for practitioners, several important areas for future research were identified.

“…Thakar and Mishra's (2010) approach is effective in the identification of comparatively tolerant species by comparing the tolerance grades between the plant species under the same environment irrespective of how tolerant the investigated species is. Whilst, Padmavathi et al's (2013) approach is useful in the selection of the true tolerant plant species using three absolute APTI Index values in spite of the environmental conditions (Zhang et al 2016). The combination of the tolerance results of the tree species based on the two approaches give a better tolerance evaluation.…”

“…The consideration of these tree species for urban greenery stems from the fact that they are tolerant and moderately tolerant at least two or three of the studied sites. Zhang et al (2016) opined that plant species with tolerant and moderately tolerant grades may be applied in green belt planning for urban and suburb areas. It was also observed that tree species had different tolerant grades at different study sites with different classification.…”

Roadside air pollution in a tropical city: physiological and biochemical response from trees

Background:The economic growth and social interaction of many developing countries have been enhanced by vehicular transportation. However, this has come with considerable environmental cost. The vehicular emissions of gases such as carbon monoxide (CO), sulphur dioxide (SO 2 ), nitrogen oxide (NOx) and volatile organic compounds (VOC's) among others are associated with vehicular transportation. The resultant effect can lead to respiratory infections in humans, as well as growth inhibition and death of animals and plants. An investigation was conducted to evaluate the impact of vehicular air pollutants on some selected roadside tree species in the Kumasi Metropolis, Ghana. Ficus platyphylla, Mangifera indica, Polyalthia longifolia and Terminalia catappa, which were abundant and well distributed along the road sides, were selected for the study. Three arterial roads in the Kumasi Metropolis, namely Accra Road (Arterial I), Offinso Road (Arterial II) and Mampong Road (Arterial III), were considered as different traffic volumes experimental sites. The KNUST campus was selected as a control site. Diurnal analysis of CO, NO 2 , SO 2 and VOC was monitored in the sample sites. Three replicates of each tree species were defined at a distance 10 m away from the edge of the road. Physiologically active leaves (20 to 25) from each tree species replicate were harvested for physiological and biochemical determination. Results:The ambient air quality data showed higher levels at the arterial road sites, which were severely polluted based on air quality index. The biochemical studies revealed reductions in leaf total chlorophyll and leaf extract pH whilst leaf ascorbic acid and relative water contents increased at the arterial road sites.Conclusion: It was found that the plants' tolerant response level to vehicular air pollution was in the order T. catappa > F. platyphylla > M. indica and P. longifolia. Based on anticipated performance index, it was revealed that M. indica, F. platyphylla and T. catappa might be performing some level of air cleaning functions along the arterial roads. Whilst P. longifolia was poor and unsuitable as a pollution sink.
