“…The concentrations of pollutants such as SO 2 and NO 2 tend to increase in the atmosphere during the winter as a result of thermal inversion, which hinders the dispersion of gases (Moraes et al, 2002;Prabapati & Tripathi, 2008;Bulbovas et al, 2015). In the present study, the difference in height between the two treatments became more significant in the winter (July to September) ( Table 1), suggesting that seasonal meteorological conditions may have affected the intensity of the effects of the pollutant on plant growth.…”

“…Prosopis cineraria, Azadirachta indica and Phoenix dactilifera plants around a refinery in Muscat (Oman) showed typical symptoms of necrosis due to exposure to SO 2 and other polluting gases (Abdul-Wahab & Yaghi, 2004). In general, the effects of SO 2 that cause leaf injury are influenced by biological factors such as inherent characteristics of the species and by the association of this gas with other pollutants, such as NO 2 (Abdul-Wahab & Yaghi 2004;Bulbovas et al 2015).…”

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.
