“…It represents the secondary formation of these metal aerosols emitted from different industries, while the cluster analysis showed that they are representative of two different patterns with secondary factors. 43 The second factor represents high loadings for Pb and Cr, and it is believed to originate from vehicle emissions/oil combustion and resuspended road dust, which mainly have source from oil combustion in urban areas with high traffic density. The third factor which presents the high loadings for Cd, Ni and Co is traced from the metallurgical units housed inside the city and municipal garbage incineration.…”

“…The source identification of this study is in agreement with the majority of the reported data and shows that the major contribution of toxic metals in the aerosols comes from traffic emissions and traffic induced road dust resuspension along with industrial emissions as recently proposed by different workers in different parts of world.

Local atmospheric aerosol particulate samples, collected as composites on daily 6-12 hour basis, at Quaid-i-Azam University campus, Islamabad, Pakistan, using high volume sampling technique, were analysed for Pb, Na, K, Fe, Mn, Cd, Cr, Ni, Zn and Co by FAAS method. The monitoring period ran from October, 2001 through March, 2002, with a total of 105 samples collected on cellulose filters, treated in part with the HNO3-based wet digestion method for metal quantification, and for particle size distribution separately. The metal content of the aerosols was examined in relation to dependence on meteorological parameters, such as temperature, relative humidity, wind speed, sun shine and pan evaporation. Statistical correlation analysis was conducted for multiple metal pairs in aerosols, and the data were examined in relation to meteorological parameters and relevant aerosol particle size fractions. The study revealed no viable strong correlation between the meteorological parameters and metal levels; in general, however, a significant positive correlation was found for temperature. A strong positive correlation was observed for PM<25 and PM2.5-10. For coarse particles (PM10-100 and PM>100), however, a negative correlation was observed. The levels of Na, K, Fe and Zn were found in the range of 1-5 microg/m3 while those for the rest of the metals in the sub microg/m3 range. Principal component analysis and cluster analysis were performed on dataset for source identification and appointment. Largest contribution (33%) was shown by the industrial emissions followed by traffic/road dust (16.7%).

“…PC2 had higher principal component loading for Fe and Mn, along with considerable contribution from Co. This revealed close association of Fe and Mn in TSP in Urban atmosphere, mainly contributed by earth crust and wind-blown soil from road dust resuspension (Ragosta et al, 2002;Quiterio et al, 2004;Shah et UZOEKWE, SA;AJAYI, ED al., 2006). On the other hand, Co, and considerable contribution from Ni and Pb loaded with PC3; these are believed to originate from residual oil combustion (Khodeir et al, 2012).…”

This study was conducted to investigate the distribution and correlation of selected trace elements (Ca, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in Yenagoa, Bayelsa State and its environs. Air particulate matter was collected gravimetrically at five stations (using a high volume portable SKC air check MTXSidekickair sampler (Model: 224-52MTX). The total suspended particulate matter samples were extracted in nitric acid and hydrochloric acid mixture, followed by the quantification of the trace elements by flame Atomic Absorption Spectrophotometric (AAS) method (Model: AA 6600, GBC Avanta PM AAS). The estimated elemental data were then subjected to a set of Multivariate statistical analysis and evaluated for their mutual variations in the urban particles. The concentrations of trace elements ( gm -3 ) found in the particulate matter were in the order of Ca>Fe>Zn>Ni>Pb>Mn>Cu>Cd>Co>Cr. On the average, the correlation of the trace elements of the study area shows strong correlations between Pb-Ni, Fe-Mn, Co-Ni, Zn-Pb, with correlation coefficients of 0.767, 0.595, 0.508, and 0.791 respectively. Principal component analysis revealed that major sources of trace metals in ambient air of the study areas were mainly emissions from automobile exhaust, industrial emissions and gas flaring.

“…Por outro lado, as mais baixas concentrações de PTS na estação do Pilar foram obtidas nos meses de primavera e verão, pois as precipitações favorecem a depuração atmosférica, promovendo a remoção das partículas suspensas por deposição úmida. 21 Este comportamento sazonal foi também observado na cidade argentina de La Plata, 22 assim como em estudos realizados em outras cidades brasileiras, como São Carlos. 23 Em cidades do hemisfério norte, como Cartagena -Espanha e Copenhagen -Dinamarca, nos meses de outono e inverno também foi observada maior concentração de PTS na atmosfera em estudos similares.…”

Recebido em 14/1/09; aceito em 23/10/09; publicado na web em 11/3/10 DETERMINATION OF TRACE METALS IN SUPENDED PARTICULATE MATTER (SPM) IN OURO PRETO CITY, MINASGERAIS. The determination of the airborne particulate matter (PTS) mass and trace metals concentrations were performed in three sites in Ouro Preto, MG, Brazil. It was evaluated 288 samples. The legal limit of annual geometric average (60 mg m -3 ) to PTS concentrations didn't exceed, but the legal limit for 24 h (240 mg m -3 ) did in three measurements. Seven metals (Al, Cr, Cu, Fe, Mn, Ni, Pb) analysed by ICP-AES were quantified in 18 samples. Aluminum and iron showed the highest concentrations, indicating the contribution of the soil and of one aluminum plant. The high nickel concentration is probably due to vehicular emissions and industrial combustion processes.Keywords: air quality; airborne particulate matter; trace metals. INTRODUÇÃOTanto a saúde da população como as construções das cidades são diretamente afetadas pela poluição ambiental, de modo particular pela poluição atmosférica. Além dos gases presentes na atmosfera, destacam-se também as partículas suspensas no ar, constituídas de poeiras, fumaças e todo tipo de material sólido e líquido que se mantém suspenso na atmosfera por causa de seu pequeno tamanho, as quais têm um papel predominante nos processos regulados pela poluição atmosférica. 1,2As partículas em suspensão, dependendo do diâmetro médio, causam perturbação porque permanecem por longos períodos na atmosfera antes de serem removidas por mecanismos de depuração e por apresentarem espécies químicas tóxicas em sua superfície, como metais pesados e diversos compostos orgânicos. Essas partí-culas são constituídas de líquidos e sólidos e seu diâmetro médio varia de alguns nanômetros a cerca de 500 mm. As que realmente interferem na qualidade do ar de regiões urbanas se concentram em duas faixas de diâmetro médio: as partículas finas (0,1 a 2,5 mm; PM 2,5 ) e as partículas grossas (1,0 a 100 mm). As partículas que possuem diâmetro médio menor do que 10 mm (PM 10 ) têm importância fundamental para o entendimento da contribuição da poluição atmosférica no ambiente, devido aos problemas relacionados à saúde humana provocados pelas mesmas. Essas partículas são respiráveis e, ao alcançar os pulmões, causam graves danos à saúde por conter componentes tóxicos ou mutagênicos em sua composição. Por outro lado, partículas com diâmetro médio superior a 100 mm têm um tempo médio de permanência no ar muito pequeno e a ação dessas partículas no ambiente é limitada. 3,4 As substâncias presentes no material particulado também podem danificar as rochas, causando prejuízos estéticos e criando condições ideais para catalisar processos de oxidação por meio de partículas de carbono e metais presentes na poeira, como manganês e ferro. 5Muitos dos efeitos sobre a saúde humana são decorrentes da inalação de material particulado de diferentes tamanhos contendo metais em sua composição. Além do tamanho das partículas e as concentrações dos metais nas mesmas, s...
