“…Stomatal resistance (R s ) expresses the extent of the inhibition of gas diffusion through stomata. In case of air pollution stress, limitation of gas diffusion is observed due to an increase of R s (Balasooriya et al 2009;Verma and Singh 2006). Our results confirm these findings, since, in Antwerp city, the decrease in SPS was larger than the increase in SD, causing a net increase in stomatal resistance by 17%.…”

“…Stomatal characteristics are often used for biomonitoring of air quality, and the majority of the results on the response of the stomatal characteristics to air pollution are unanimous (Balasooriya et al 2009;Elagoz et al 2006;Verma and Singh 2006): to optimise stomatal closure efficiency, SD increases, and SPS decreases due to increasing levels of air pollution. Our study confirms these results, since SD was increased (although not significantly) by 8.4% and SPS was significantly decreased by 24% in Antwerp city compared to Zoersel.…”

In this study, we assess the potential of white willow (Salix alba L.) as bioindicator for monitoring of air quality. Therefore, shoot biomass, specific leaf area, stomatal density, stomatal pore surface, and stomatal resistance were assessed from leaves of stem cuttings. The stem cuttings were introduced in two regions in Belgium with a relatively high and a relatively low level of air pollution, i.e., Antwerp city and Zoersel, respectively. In each of these regions, nine sampling points were selected. At each sampling point, three stem cuttings of white willow were planted in potting soil. Shoot biomass and specific leaf area were not significantly different between Antwerp city and Zoersel. Microclimatic differences between the sampling points may have been more important to plant growth than differences in air quality. However, stomatal pore surface and stomatal resistance of white willow were significantly different between Zoersel and Antwerp city. Stomatal pore surface was 20% lower in Antwerp city due to a significant reduction in both stomatal length (-11%) and stomatal width (-14%). Stomatal resistance at the adaxial leaf surface was 17% higher in Antwerp city because of the reduction in stomatal pore surface. Based on these results, we conclude that stomatal characteristics of white willow are potentially useful indicators for air quality.

“…Pollutants induced increased cell permeability may cause a loss of water from guard cells to make them flaccid, which results in stomatal closure. Further, encrustation or dust deposition on leaf cuticle due to particulate penetration in to the epicuticular wax may reduce the integrity of the incident light hampering photosynthesis which may, further lead to an accumulation of CO 2 in to the sub-stomatal cavities and hence stomatal closure (Verma and Singh, 2006). Air born particulate also causes stomatal clogging.…”

Experimental potted plants of Duranta repens has been exposed to air pollution at major traffic crossingsAmphalla chowk, Dogra chowk, Bikram chowk, Satwari chowk of Jammu city and also inside University Campus in the department which has been taken as a reference site. Sets of 10 plants were kept at each site and analyzed for various micro morphological, anatomical and biochemical parameters to assess the changes due to air pollution. Analysis of data revealed that micro-morphological parameters viz. stomatal frequency, epidermal cell frequency increased significantly while others like size of the stomata, epidermal cells and length, breadth ratio of the epidermal cells decreased significantly in plants kept at polluted location. All the anatomical parameters such as thickness of midrib region, midrib adjoining region, spongy tissue, upper epidermis and vascular bundles decreased significantly in exposed plants. Among biochemical parameters chlorophyll b decreases significantly while ascorbic acid increases significantly. Air Pollution Tolerance Index (APTI) has also been calculated and found to increase significantly in plants kept at polluted location which indicate that the Duranta repens serve as sink to air pollutants and can be effectively employed for phyto-monitoring auto exhaust pollution along the road side of the busy traffic ways.

“…Metal uptake in higher vascular plants takes place through their root system, additionally through the leaves and, therefore, it is difficult to distinguish whether the accumulated elements originate from the soil or from the air (Harrison and Johnston 1987;Verma and Singh 2006).…”

Leaves of the deciduous tree species, horse chestnut (Aesculus hippocastanum L.) and Turkish hazel (Corylus colurna L.) were used as accumulative biomonitors of trace metal pollution in the urban area of Belgrade. Using differential pulse anodic stripping voltametry, trace metal concentrations (Pb, Cu, Zn, Cd) were determined at the single leaf level (ten leaves per species, per month), during two successive years with markedly different atmospheric level of trace metals. Increased trace metal concentrations in the leaves of A. hippocastanum reflected elevated atmospheric trace metal pollution, whereas C. colurna L. did not respond accordingly. The contents of Pb and Zn in soil over the same period also followed this trend. Anatomical analyses, in young as well as in old leaves of both species, indicated typical foliar injuries of plants exposed to stressful air conditions. Water relations that correspond to leaf age may have contributed to the considerable trace metal accumulation in leaves.
