“…Green areas deliver a series of natural functions, often named ecosystemic services, including the air and water purification, healthier soils, improvement of the urban climate and microclimate (Millennium Ecosystem Assessment, 2003;Wolch, et al, 2014;Nita, 2016), playing an important role in water infiltration in the ground and in the restoration of aquifers (Xiao, et al 2006;Bartens, et al, 2008), water interception at the tree canopy level (Xiao, et al, 2006), as well as the flooding control (Lull, Sopper 1969;Craul, 1992;Chen, et al, 2006 quoted by Wolch, et al, 2014), diminishing the environment pollution by capturing the dust particles (Nowak, et al, 2006;Mitchell, et al, 2010;Dogon-Yaro, et al, 2016), increase of biodiversity and habitats (Lima, et al, 2013;Petrisor, 2015;Hüse, et al, 2016), low noise (Fang, Ling, 2003;Van Renterghem, et al, 2012;Wolch, et al, 2014).…”

The urban vegetation needs adequate monitoring and conservation, being a critical resource of urban landscape. To its deeply esthetic values, the practical values and, respectively, ecosystem services delivered by the urban biodiversity are added (amelioration of the environment and urban microclimate, flood control, diminishing of the environmental pollution, increasing of biodiversity and habitats etc.). Accurate remote sensing techniques have been used widely in locating and mapping urban vegetation (Light Detection And Ranging-LiDAR, satellite images).The purpose of this study is to point out the vegetation status in correlation with the number of the bird species (as indicator of the ecosystem's health), using remote sensing techniques (Landsat satellite images), between 1991-2006 in Bucharest, Romania's capital. Rapid urban evolution of Bucharest led to important changes within the structure of the city, underlined by the increasing of the built area to the detriment of the green one. The intensity of the urbanization rate also led to the decreasing of the number of the bird species. The results obtained through analysis of satellite images indicate the necessity to acquire the up-to-date information related to the vegetation status in order to establish in the future, through urban landscape projects, protection measures for the vegetation cover and for the bird habitats in Bucharest Municipality.

“…At the species level, the great difference among the three species indicated that different species or vegetation types have distinct capacities for particle retention. These differences may be highly related to vegetation types of species (Beckett et al, 2000a;Popek et al, 2013), leaf structure (Mitchell et al, 2010;Wang et al, 2006), deposition processes (Freer-Smith et al, 2005;Sternberg et al, 2010), location of sample trees, and even meteorological conditions (Beckett et al, 2000b). Among these factors, vegetation types of species and leaf structure are the dominant ones, since the leaves were collected from the same location in our study.…”

It is widely accepted that urban plant leaves can capture airborne particles. Previous studies on the particle capture capacity of plant leaves have mostly focused on particle mass and/or size distribution. Fewer studies, however, have examined the particle density, and the size and shape characteristics of particles, which may have important implications for evaluating the particle capture efficiency of plants, and identifying the particle sources. In addition, the role of different vegetation types is as yet unclear. Here, we chose three species of different vegetation types, and firstly applied an object-based classification approach to automatically identify the particles from scanning electron microscope (SEM) micrographs. We then quantified the particle capture efficiency, and the major sources of particles were identified. We found (1) Rosa xanthina Lindl (shrub species) had greater retention efficiency than Broussonetia papyrifera (broadleaf species) and Pinus bungeana Zucc.(coniferous species), in terms of particle number and particle area cover. (2) 97.9% of the identified particles had diameter ≤10 μm, and 67.1% of them had diameter ≤2.5 μm. 89.8% of the particles had smooth boundaries, with 23.4% of them being nearly spherical. (3) 32.4%-74.1% of the particles were generated from bare soil and construction activities, and 15.5%-23.0% were mainly from vehicle exhaust and cooking fumes.

“…La deposición de hollín se concentra en la superficie de las hojas de los árboles aledaños a las fábricas harineras, el cual puede llegar a formar una película sobre el follaje, restringiendo la absorción lumínica y el proceso de fotosíntesis, afectando de esta manera el equilibrio dinámico de la vegetación arbustiva y, por tanto, es probable la aparición de efectos adversos para la salud (De Kok et al, 2006;Mitchell et al, 2010;Novák et al , 2014) en la población del ecosistema urbano de la zona de influencia. Las partículas de hollín también pueden obstruir las vías respiratorias aumentando la secreción de moco (Martínez, 2010) induciendo efectos de disfunción celular (Oberdörster et al, 2005).…”

ResumenEl objetivo de la investigación fue cuantificar la deposición de hollín en el follaje de la vegetación arbustiva, formada principalmente por ficus (Ficus macrophylla), en el ecosistema urbano de Florida Baja-Chimbote durante el periodo de máxima producción (mayo, junio y julio) en las fábricas productoras de harina y aceite de pescado. El aire de esta zona está cada vez más distante de ser aire limpio por contener altas concentraciones (187.6 g/m 3 en 24 h) de partículas suspendidas totales (PST), provenientes de la actividad industrial, comercial, urbana, del parque automotor y de los procesos naturales. Las partículas de hollín generadas por pirólisis en las calderas de las fábricas productoras de harina y aceite de pescado (a partir del diesel) forman parte de una gama de partículas aglomeradas comúnmente de forma esférica, con diámetros aerodinámicos de 0.1 a 2.5 m (partículas finas) y menores a 0.1 m (partículas ultrafinas), las cuales pueden penetrar con mayor facilidad en los alvéolos pulmonares produciendo efectos adversos a la salud. Estas partículas fueron cuantificadas por gravimetría, metodología restringida para cuantificar partículas menores a 10 m (PM-10, PM-5, PM-2.5) siendo necesario utilizar, para este caso, equipos de alto volumen para su monitoreo, aplicaciones tecnológicas complementarias y tecnología de control. En el periodo de mayor actividad de las fábricas productoras de harina y aceite de pescado se ha encontrado una cantidad promedio de 1.08 mg de hollín/cm 2 ; equivalente a 0.108 toneladas métricas de hollín/hectárea adsorbido en el follaje de los árboles de ficus, dicho nivel de contaminación es 316.79 veces superior al promedio obtenido en la primera campaña de muestreo (periodo de veda en Chimbote). Palabras clave: deposición de hollín, adsorción, pirolisis, partículas suspendidas totales, partículas finas, partículas ultrafinas. AbstractThe objective of this investigation was to quantify the deposition of soot on shrub vegetation foliage, mainly comprised of ficus (Ficus macrophylla), in the urban ecosystem of Florida BajaChimbote during the highest production period (may, june and july) of fish flour and fish oil producing factories. The air from this zone is gradually far from being clean air due to the high concentration (187.6 g/m 3 ; in 24 h) of Total Suspended Particles (TSP), which are generated by automobiles, by natural processes and in industrial, commercial and urban activities. Soot particles generated by pyrolysis in the boilers of fish flour and fish oil producing factories (from diesel) belong to a group of commonly spherical agglomerated particles, with aerodynamic diameters of 0.1 to 2.5 m (fine particles) and smaller than 0.1 m (ultrafine particles), which can easily penetrate pulmonary alveoli with adverse consequences on health. These particles were quantified gravimetrically, a methodology restricted to the quantification of particles smaller than 10 m (PM-10, PM-5, PM-2.5). In this case, high volume equipment for monitoring, complementary tech...
