“…This may be because of over classification with the use of both primary and secondary discharge codes. However, an increase in cardiovascular and respiratory hospitalizations is consistent with the literature [8,16,24,50,66], though some literature has shown no increase in cardiovascular hospitalizations [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] or mortality [67]. Figure 4 displays the percent increase in hospital admissions for the haze period compared to the non-haze period in the affected region for all specific diagnoses of interest with single and distributed lag models.…”

“…Each year, combustion products from local and distant wildfires impact large populations worldwide [5,[7][8][9][10][11][12][13]. The atmospheric pollutant that most consistently increases with biomass smoke from wildfires is suspended fine particulate matter (PM), which is commonly associated with increased mortality and morbidity [1,4,[14][15][16][17].…”

“…The majority of these studies have examined the impact on nearby local communities of exposures to wildfire aerosols. Associated health effects include increased emergency department visits and hospital admissions for chronic obstructive pulmonary disease (COPD), bronchitis, asthma and chest pain [7,13,15,[34][35][36][37]. For example, the San Diego wildfire in October 2003 caused the daily 24 h average PM 2.5 concentrations to exceed 150 µg/m 3 , and was associated with significant increases in hospital room emergency room visits for asthma, respiratory problems, eye irritation, and smoke inhalation [38], and increased eye and respiratory symptoms, medication use and physician visits in children living in the San Diego area [30].…”

In July 2002, lightning strikes ignited over 250 fires in Quebec, Canada, destroying over one million hectares of forest. The smoke plume generated from the fires had a major impact on air quality across the east coast of the U.S. Using data from the Medicare National Claims History File and the U.S. Environmental Protection Agency (EPA) National air pollution monitoring network, we evaluated the health impact of smoke exposure on 5.9 million elderly people (ages 65+) in the Medicare population in 81 counties in 11 northeastern and Mid-Atlantic States of the US. We estimated differences OPEN ACCESS ISPRS Int. J. Geo-Inf. 2014, 3 714 in the exposure to ambient PM 2.5 -airborne particulate matter with aerodynamic diameter of ≤2.5 µm-concentrations and hospitalizations for cardiovascular, pulmonary and injury outcomes, before and during the smoke episode. We found that there was an associated 49.6% (95% confidence interval (CI), 29.8, 72.3) and 64.9% (95% CI, 44.3-88.5) increase rate of hospitalization for respiratory and cardiovascular diagnoses, respectively, when the smoke plume was present compared to before the smoke plume had arrived. Our study suggests that rapid increases in PM 2.5 concentrations resulting from wildfire smoke can impact the health of elderly populations thousands of kilometers removed from the fires.

“…The pollutants can most heavily contaminate the 40-60 m wide roadside zone, while the overall polluted area extends to the approximately 300 m wide zone [1][2][3], and the number concentration of particles smaller than 0.3 µm in diameter, which can be inhaled and cause serious health effects, is dominating [4,5].…”

A semi-empirical model intended for simulation of dispersion of aerosol particles with the diameter larger than 0.05 µm near roadways is proposed. The pollution source is simulated as a cut-off cylinder, formed due to traffic pollution on the roadways at the initial time moment and uniformly filled with aerosol particles. The aerosol particle transfer by the wind further from the roadway is simulated, its settling being influenced by the gravitation, particle buoyancy, and thermal pollutant plume rise effects. Good agreement between the model and experimental results is obtained.

“…Roadsides in urban areas are usually polluted with heavy metals mostly derived from traffic: motor vehicle emissions, abrasion of tyres, brake linings as well as road surface, turbulence of dust due to vehicular movement, dispersion of construction material, etc. (Petrovsky and Ellwood, 1999;Gautam et al, 2004, Ovadnevaite et al, 2006. Plants not only have an ornamental function in urban areas, but they also may improve the quality of urban life (Akbari, 2002;Brack, 2002).…”

The aim of this research is to study the behavior of different forest species in accordance with their ability to retain heavy metals on their leaves in order to select the most suitable species for urban and peri-urban use, which will contribute to the reduction of the continuously growing atmospheric pollution in the cities. Five species were studied: Cupressus arizonica, Albizia julibrissin, Platanus orientalis, Celtis australis and Ligustrum japonicum. 360 leaf samples were collected and two treatments (non-washed and washed sheets) were applied on them. The determinative estimation of the concentration of metals in the clear filtrate was carried out with the use of ICP-OES inductively coupled plasma optical emission spectrometry. In order to correlate the concentration of heavy metals in leaves with the silvicultural characteristics of species, the following characteristics were measured in 20 individuals per species: diameter at breast height, total height of tree, crown beginning height and crown's diameters. Statistically significant differences between the studied species were found for all metals. In addition, not a single species was found to retain the highest concentration of all. Metal concentration on leaves' surface in declining order was: (Mn) > (Cu) > (Zn) > (Pb) > (Cr) > (Ni) > (Cd). The factor of height is significant both in the upper and lower layer of the crown. Broadleaves' species as Albizia julibrissin with compound leaves capture significant heavy metals as conifer species.
