The values of LLCR from the exposure to PAHs at ) and SUI (3.62 × 10 -4 ) were also exceed the health guideline but significantly lower than the values in urban sites.…”

The relationships between polycyclic aromatic hydrocarbons (PAHs) in PM 2.5 in outdoor and indoor environments of hotels were examined in Jinan, China from January 6, 2016 to January 29, 2016. The mean concentrations of ∑PAHs for all sampling sites showed the following ascending order: suburban indoor (SUI, 39.58 and SUI were all less than 1, indicating that the PAHs were mainly infiltrated from the outdoor environment. At URI 2 , 2-ring and some 3-and 4-ring PAHs were mainly produced indoors due to cooking, whereas the 5-7-ring PAHs were mainly infiltrated from the outdoor environment. The diagnostic ratios and principal component analysis indicated that emissions from combustion of coal, biomass, diesel fuel and gasoline were the main sources of PAHs in the study area. The impacts of health risk assessment of PAHs suggested that the health risks in the outdoor environment were more severe than those in the indoor environment and the health risks in urban area were significantly higher than those in the suburban area in Jinan.

“…This fraction can be further subdivided into coarse (PM 2.5-10 ) and the fine fractions (PM 2.5 ). Many researchers have undertaken studies of PM designed to identify its chemical composition (Espinosa et al, 2001;Allen et al, 2001;Dallarosa et al, 2008;Hieu and Lee, 2010;Wimolwattanapun et al, 2011) and its morphological properties (Micic et al, 2003;Liu et al, 2005;Adamo et al, 2008;Witt, et al, 2010;Rosasco et al, 2011;Chithra and Shiva Nagendra, 2013). Such researches have being made to understand the behavior of these pollutants and their relationships with meteorological conditions and also their links with harmful impacts to health, such as respiratory and cardiovascular diseases (Schwartz et al, 1996;Borja-Arbuto et al, 1998;Neas et al, 1999;Laden et al, 2006;Bourotte et al, 2007;Lepeule et al, 2012).…”

This research aimed to evaluate the air quality, by determining the concentrations of PM 2.5-10 , PM 2.5 and the metallic elements Al, Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn and Hg in the leaf part of ryegrass (Lolium multiflorum) in an area close to Schmidt Stream, at the lower section of Sinos River Basin (SRB), in a research campaign of six months, from October 2013 to March 2014. The particles collected in the PM sampling were analyzed by Scanning Electron Microscopy (SEM) combined with Energy Dispersive X-ray Spectrometry (EDS), in order to study their morphology and chemical composition. The mean concentration of PM 2.5-10 was 9.1 µg m . Concentrations of metallic elements, especially Pb, Cr and Zn, were classified as Class 4 (very high pollution levels), according to the classification proposed by Klumpp et al. (2004). Chemical and morphological analysis of PM revealed the presence of particles of biological origin, soot (Cr, Fe, Ni, Zn, Cd, Hg and Pb), salts (KCl) and soil resuspension (Al and Si). The integrated study methodology, employing environmental variables, such as PM and ryegrass, can be of help in the preparation of wide-ranging environmental diagnoses, in addition providing information needed to develop precautionary measures designed to minimize the effects of atmospheric pollution that takes into consideration the environment's supportive capacity and environmental quality.Keywords: air pollution, particulate matter, biomonitoring, lolium multiflorum, mev/eds.

Estudos integrados empregando variáveis ambientais como o MP e o biomonitoramento com azevém podem auxiliar na elaboração de diagnósticos ambientais robustos, além de fornecer informações para o desenvolvimento de medidas de precaução que considerem a capacidade de suporte do meio ambiente e que visem à minimização dos efeitos prejudiciais da poluição atmosférica.

We investigated the relationship between wintertime 1-min mean urban indoor particulate matter mass concentrations for particles with aerodynamic diameter of < 1 µm (PM 1 ) and outdoor atmospheric conditions. Particle concentrations were measured by two light-scattering laser photometers. Aerosol monitors were placed in the ground and first floor corridors of an university building, with inlets at heights of 1.7 m above the floor. The building is located in residential area of Zagreb, Croatia. During the experiment usual student and employee activities were occurring within the building. Surface meteorological data were collected at a nearby outdoor location. Results show the dependence of indoor PM 1 on outdoor meteorology, with the strongest responses to air temperature and relative humidity, whilst global radiation impacts were almost negligible. Response times varied from 1.2 hours (for relative humidity) to 2.7 days (for global radiation). Furthermore, elevated mean concentrations point to the 8-9 km distant industrial zone. Both, PM 1 and meteorological data series exhibited semidiurnal, diurnal and the long-term (about 10-11 days and about 21 day) periodicity. The long-term periodicity of PM 1 time series might be associated with Rossby waves. Possible association with Rossby waves needs to be investigated further.
