“…Biomagnetic monitoring, which was developed to indirectly quantify the amount of particles on the leaf surfaces, has been used as a proxy in recent studies (Barima et al, 2014;Hofman et al, 2014;Lehndorff et al, 2006;Mcintosh et al, 2007;Mitchell et al, 2010;Speak et al, 2012). The range of published data using various measurement methods is extensive, which reflects the complex factors that affect the accumulation of PM on the leaf surfaces, e.g., different plant species, PM concentrations and meteorological conditions.…”

“…Ambient PM can originate from natural or anthropogenic sources. In urban areas, the ambient PM is primarily of anthropogenic origin and typically comprises a mixture of acids, heavy metals, black carbon, organic chemicals, and soil or dust particles [1]. This pollution can adversely affect the atmospheric environment, human health, and even the global climate.…”

Due to the highly heterogeneous and dynamic nature of urban areas in Chinese cities, air pollution exhibits well-defined spatial variations. Rapid urbanization in China has heightened the importance of understanding and characterizing atmospheric particulate matter (PM) concentrations and their spatiotemporal variations. To investigate the small-scale spatial variations in PM in Xiamen, total suspended particulate (TSP), PM10, PM5 and PM2.5 measurements were collected between August and September in 2012. Their average mass concentrations were 102.50 μg·m , respectively. Organic carbon (OC) and elemental carbon (EC) in PM2.5 were measured using thermal optical transmission. Based on the PM concentrations for all size categories, the following order for the different functional areas studied was identified: hospital > park > commercial area > residential area > industrial area. OC contributed approximately 5%-23% to the PM2.5 mass, whereas EC accounted for 0.8%-6.95%. Secondary organic carbon constituted most of the carbonaceous particles found in the park, commercial, industrial and residential areas, with the exception of hospitals. The high PM and EC OPEN ACCESSAtmosphere 2015, 6 235 concentrations in hospitals were primarily caused by vehicle emissions. Thus, the results suggest that long-term plans should be to limit the number of vehicles entering hospital campuses, construct large-capacity underground parking structures, and choose hospital locations far from major roads.

“…Lead and Cadmium Phytoavailability and Human Bioaccessibility for Vegetables Exposed to Soil or Atmospheric Pollution by Process Ultrafine Particles Tiantian Xiong, Thibault Leveque, Muhammad Shahid, Yann Foucault, Stéphane Mombo, and Camille Dumat* A t the global scale, atmospheric pollution by particulate matter (PM) with different origins, size distribution, and chemical composition is observed (Salma et al, 2005;Barima et al, 2014). The presence of highly reactive ultrafine particles in urban areas can induce environmental and health risks (Knibbs and Morawska, 2012;Marris et al, 2012;Austruy et al, 2014).…”

Lead and Cadmium Phytoavailability and Human Bioaccessibility for Vegetables Exposed to Soil or Atmospheric Pollution by Process Ultrafine Particles

When plants are exposed to airborne particles, they can accumulate metals in their edible portions through root or foliar transfer. There is a lack of knowledge on the influence of plant exposure conditions on human bioaccessibility of metals, which is of particular concern with the increase in urban gardening activities. Lettuce, radish, and parsley were exposed to metal-rich ultrafine particles from a recycling factory via field atmospheric fallouts or polluted soil. Total lead (Pb) and cadmium (Cd) concentrations in of the edible plant parts and their human bioaccessibility were measured, and Pb translocation through the plants was studied using Pb isotopic analysis. The Pb and Cd bioaccessibility measured for consumed parts of the different polluted plants was significantly higher for root exposure (70% for Pb and 89% for Cd in lettuce) in comparison to foliar exposure (40% for Pb and 69% for Cd in lettuce). The difference in metal bioaccessibility could be linked to the metal compartmentalization and speciation changes in relation to exposure conditions. Metal nature strongly influences the measured bioaccessibility: Cd presents higher bioaccessibility in comparison to Pb. In the case of foliar exposure, a significant translocation of Pb from leaves toward the roots was observed. To conclude, the type of pollutant and the method of exposure significantly influences the phytoavailability and human bioaccessibility of metals, especially in relation to the contrasting phenomena involved in the rhizosphere and phyllosphere. The conditions of plant exposure must therefore be taken into account for environmental and health risk assessment.
