“…pH signals the occurrence of detoxication process in plant necessary for tolerance (Thawale et al 2011). Terminalia catappa, Mangifera indica, Ficus platyphylla and Polyalthia longifolia leaf extract pH in this study were found to be acidic in nature at the arterial road sites.…”

“…Leaf extract pH, relative water content (RWC), total chlorophyll content and ascorbic acid were used to determine (Thawale et al 2011) tolerance and sensitivity of the tree species to vehicular emissions. They were taken as numerical expression to get an observed value indicating Air Pollution Tolerance Index (APTI) as proposed by Singh and Rao (1983).…”

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.

“…The literature has reports of phytotoxicity caused by air pollutants in araça trees and other bioindicator species. Changes in the levels of chlorophylls (including symptoms of chlorosis and necrosis), sugars, proteins and other organic components (Thawale et al, 2011;Rai, 2016) are some physiological effects that may affect biomass production and plant growth. Studies on P. cattleianum submitted to the effects of pollutants in Brazil have revealed significant alterations in the antioxidant metabolism and vegetative growth of this plant (Moraes et al, 2002;Alves et al, 2011).…”

Psidium cattleianum is a bioindicator species of air pollutants, notably NO x and SO 2. The aim of this study was to evaluate the effects of air emissions from a mining industry in Brumado, Bahia, Brazil, on the morphophysiological characteristics of P. cattleianum. A field experiment was carried out with potted plants in two distinct areas: (1) permanent exposure to NO x and SO 2 emissions; and (2) free from the influence of the plume formed by these air pollutants (control). Plant height, leaves area and quantity, leaves, stem and roots dry mass, and chlorophyll and soluble sugar contents were evaluated. In the plants exposed to the pollutant plume, height growth inhibition and leaf size and quantity reduction were observed, besides showing symptoms of chlorosis and necrosis. Dry matter production was also lower in all organs. The chlorophyll a content was lower, but chlorophyll b content did not change. The soluble sugars content was not affected by the pollutants. It was concluded that the atmospheric emissions from the mining industry negatively affect the physiological characteristics of P. cattleianum, inhibiting the plant growth.

“…The former may be due to more pollution stress by hindering chlorophyll biosynthesis or various chlorophyll degradation products (fluorescent/non-fluorescent chlorophyll catabolite) or stress induced chlorosis, pheophytinisation, reverse bleaching, etc. (Thawale ., 2011). Conversely, higher chlorophyll content was observed mostly during morning hours which might be due to plants' innate tolerance mechanism against air pollutant-induced oxidative stress.…”
