“…22,23 The extracted solution was filtered by using a Whatman n o 41 (WH1441-110) filter, completed to 50 mL with ultrapure water and kept in pre-cleaned polyethylene bottles in the refrigerator until analyses. 24,25 Filter and reagent blanks were processed following the same treatment. The metal content of the blanks for Ca, Mg, Mn, Fe, Zn, Cu, Co, Ni, Al, Cd and Pb was less than 5% of samples average content.…”

Amostras de material particulado total (MPT) e MP 10 foram coletadas numa estação de ônibus, no período de agosto de 2006 a fevereiro de 2007. Na área, as únicas fontes importantes de emissão de poluentes são os ônibus, já que os veículos leves representam apenas 1-2% do fluxo total e não são desenvolvidas outras atividades no local. As concentrações de metais foram determinadas por espectroscopia de emissão por plasma indutivamente acoplado (ICP-OES). Os metais mais abundantes foram Ca, Mg, Fe e Al, que correspondem a 50,1%; 24,2%; 6,5% e 18,7%, respectivamente, do conteúdo metálico. O Co, Ni, Cd, Cr e Pb foram encontrados em níveis inferiores ao seu limite de detecção, exceto para algumas poucas amostras. Os fatores de enriquecimento calculados, mostram que o Zn e o Cu são devidos provavelmente à composição do combustível e do óleo lubrificante. O Ca, Mg e Al podem ser atribuídos à resuspensão de poeira, enquanto que o Fe pode ser devido tanto à ressuspensão de poeira como as emissões dos veículos.Total particulate matter (TSP) and PM 10 samples were collected in a bus station, in the period of August 2006 to February 2007. Buses are the only significant emission sources in this area once light duty vehicles represent about 1-2% of total flux and no other activities are developed in the location. Concentrations of metals in the samples were determined by inductively coupled plasma optical emission spectroscopy (ICP-OES). Ca, Mg, Fe and Al were the most abundant elements and accounted for about 50.1%, 24.2%, 6.5% and 18.7% of the total metal content. Co, Ni, Cd, Cr and Pb were under detection limits except for a few samples. Calculated enrichment factors show that Zn and Cu are probably due to fuel and oil composition. Ca, Mg and Al may be attributed to dust resuspension while Fe may be due to both dust resuspension and contribution of vehicles.

“…Airborne particulate matter (≤10 µm, measured as: µg/m 3 per day, i.e. PM 10 ) was used as an initial index of environmental pollution at a site because it is known to contain a wide variety of contaminants derived from anthropogenic sources such as metals (BeceiroGonzalez et al, 1997;Kim et al, 2002), polycyclic aromatic hydrocarbons (Manoli et al, 2002), sulfates (Roosli et al, 2001), ammonium compounds (Roosli et al, 2001), chlorine compounds (Esbert et al, 2001) and silicates (Esbert et al, 2001). In addition, the concentration of many of these contaminants in the air tends to be positively correlated with the total amount of atmospheric particulates (Bilos et al, 2001;Chow et al, 2002) and PM 10 has been shown to be a good indicator of soil metal contamination .…”

Assessing the genetic structure of natural populations differentially impacted by anthropogenic contaminants can be a useful tool for evaluating the population genetic consequences of exposure to pollution. In this study, measures of genetic diversity at variable-number-tandem-repeat loci in six dandelion populations (3 urban and 3 rural) showed patterns that may have been influenced by exposure to environmental contaminants. Mean genetic similarity among individuals within a population was significantly and positively correlated with increasing levels of airborne particulate matter (< or = 10 microm, PM10) and soil concentrations of four metals (Cd, Fe, Ni and Pb). In addition, mean genetic similarity was always significantly higher at the urban sites compared to rural sites. There was a significant negative correlation between the number of genotypes at a site and increasing amounts of PM10, concentrations of five soil metals (Cd, Cu, Fe, Ni and Pb), leaf tissue levels of Fe and a significant positive correlation between the extent of clonality at a site and levels of PM10 and soil concentrations of five metals (Cd, Cu, Fe, Ni and Pb). Although, this study does not directly establish a causal link between the specific contaminants detected at the study sites and differences in genetic diversity, our data are consistent with the hypothesis that pollution-induced selection has contributed in some fashion to the lower genetic diversity found at the urban sites.

“…Causing serious environmental risks, its effect has been examined extensively (Onder and Dursun 2006). Some studies show that total suspended particles (TSP) and metal concentrations follow a similar pattern but Beceiro-Gonzalez et al (1997) found that, for the same area, TSP and PM 10 metal distribution patterns were different (O'Donnell et al 1976). There are many investigations on Pb, Cd, Hg, and other heavy metal levels in air and their toxic effects (Onder and Dursun 2006).…”

Atmospheric particulate matter may exert serious health hazards because of its chemical characteristics. The main objective of this study is to assess the concentrations of total suspended particles (TSP), particulate matter (PM) with an aerodynamic diameter ≤10 μm (PM 10 ), and airtransmitted particulate trace metals in Tehran University (a central location in Tehran, capital of Iran) ambient air, for the period of 5 months viz. February-June 2007. Furthermore, the present work examines the daily levels of fine particles in comparison with the proposed limiting values from the U.S. Environmental Protection Agency (65 μg m −3 for PM 10 ). The sampling for TSP and PM 10 was performed using a high-volume sampler. The TSP and PM 10 levels were determined by gravimetry and the metals by flame atomic absorption spectrometry. Arithmetic means of 151±44 µg m −3 and 90±38 µg m −3 were determined for TSP and PM 10 , respectively. Comparing with EPA primary and secondary air quality standards, only PM 10 concentrations in 3 days were higher than the standard values. Heavy metal content of both TSP and PM 10 , such as chromium (Cr), cadmium (Cd), and lead (Pb), were also analyzed separately during the same period using atomic absorption spectrometry.
