“…Under field conditions, no relationship could be established between APM concentrations and the germination of PGs from Cichorium intybus (Jaconis et al 2017). Pollen viability in Pinus nigra was negatively correlated with SO2, PM10 and NOx concentrations (Gottardini et al 2004).…”

“…However, quantitative studies on the deposition of APM on PGs, which would make it possible to determine these doses, are particularly lacking or present positive artefacts related to the sampling method of PGs (Choël et al 2020;. A link between atmospheric concentrations of APM and plant reproduction has not yet been formally demonstrated, although the deleterious effect of gas pollution on pollen performance is widely accepted (Jaconis et al 2017;Sénéchal et al 2015;Wolters and Martens 1987).…”

Atmospheric particulate matter deposition on birch catkins and pollen grains before pollination

Birch is the most allergenic tree species in northern and central Europe. Airborne birch pollen concentrations are observed to be on the rise for several decades. Health hazard due to birch pollen grains (BPGs) can worsen due to particulate air pollution.The prevalence of the intimate mixture of BPGs with atmospheric particulate matter (APM) at the single pollen grain level is still unraveled. In this study, APM transfer mechanisms to birch catkins and BPGs prior to pollination were investigated at an urban-industrial and a peri-urban site in northern France. The surface of catkins was heavily polluted with micrometer-sized particles. Conversely, BPGs were relatively unpolluted with on average 0.1 particle.BPG -1 . Differences in the chemical composition of adhered particles were observed as a function of the sampling sites.In contrast, no significant difference was found in terms of surface concentrations of APM adhered to BPGs and catkins between the two sites. Comparison of the number of particles deposited per pollen grain according to whether they were harvested from catkins or collected while airborne suggests that particulate pollution of pollen occurs preferentially after pollen shedding, either by impaction or coagulation mechanisms with other suspended APM or by pollen settling on dust-contaminated surfaces followed by resuspension.

“…However, these studies use particularly high particle-topollen ratios and chemical compositions that are not very representative of real atmospheric particles. It was also shown that APM does not interfere with the germination of Cichorium intybus pollen along roadsides (Jaconis et al, 2017).…”

“…The ability of plants to retain PM is not only related to the planted area, but also has a strong correlation with the plant leaf surface morphology. It has been reported that plant leaves with fuzzy, furrowed surfaces have a stronger dust retention capacity than leaves with smooth, thin, waxy layers (De Nicola et al, 2008;Saebø et al, 2012;Jaconis et al, 2017). The overall plant retention of PM is a combination of retention on the leaf surface and in the waxy layer, and it has also been shown that the thickness of the waxy layer is a key factor affecting the plant retention of PM (Sun et al, 2018;Choi et al, 2021).…”

The adsorption of particulate matter (PM) by the leaves of urban plants can effectively reduce the particulate matter concentration in the atmosphere. The use of climbing plants to abate particulate matter is an important means of urban greening in China, which is rich in climbing plant species. In this study, three evergreen climbing plants were selected to assess their ability to adsorb particulate matter and determine their physiological responses to particulate pollution. PM deposition was determined gravimetrically. There were four key results. 1) The adsorption capacity of the three evergreen climbers followed the order of Hedera nepalensis var > Ficus pumila Linn > Euonymus fortunei, and was significantly higher in an overpass environment than in a campus environment for all three species. 2) The seasonal characteristics of particulate adsorption by the three types of climbers in both the overpass and campus environments followed the order of winter > autumn > spring > summer. 3) The net photosynthetic rate of the three climbing plants was significantly affected by particulate matter in a size dependent manner, with fine particulate matter on the plant leaf surface and coarse particulate matter in the leaf waxy layer being important factors affecting plant photosynthesis. 4) Particulate pollution led to changes in the activities of plant protective enzymes in plants, with increases in the superoxide dismutase (SOD) and peroxidase (POD) activity, and the malondialdehyde (MDA) and soluble protein contents. There were different trends in the soluble sugar content among the different plant species. In conclusion, F. pumila had a strong resistance to particulate pollutants, while H. nepalensis was considered suitable for planting in polluted areas where it could improve ambient air quality by adsorbing large amounts of particulate matter.
