1. Characterization, Source Apportionment and Health Risk Assessment of PM2.5 for a Rural Classroom in the Amazon: A Case Study
Classrooms are microenvironments in which children and teenagers may be exposed to fine particulate matter (PM2.5). Iranduba is a rural city in the Amazon region close to many brick kilns and road with high traffic levels. In this study, indoor and outdoor PM2.5 levels were measured in a classroom in Iranduba, and the PM2.5 exposure effects on student’s he

3. ALTERNATIVE SOURCE APPORTIONMENT IN THE SURROUNDING REGION OF A LARGE STEEL INDUSTRY APPLYING Tillandsia usneoides AS BIOMONITOR
From the beginning of its operation, this large steel industrial complex in the Santa Cruz Industrial District, Rio de Janeiro, Brazil, with an annual capacity of 5 million tons, has been at the center of controversy related to its atmospheric emissions. Since the air filter used for its routine air particulate monitoring network is not appropriate for a sou

4. Composição elementar do aerossol atmosférico na região central da Bacia Amazônica
The processes and sources that regulate the elemental composition of aerosol particles were investigated in both fine and coarse modes during the dry and wet seasons. One hundred and nine samples were collected from the biological reserve Cuieiras - Manaus from February to October 2008, and analyzed together with 668 samples that were previously collected at

6. O controle dos preços de transferência: aplicação em operações financeiras e derivativos / International transfer pricing on financial instruments and derivatives
O controle dos preços de transferência está amparado no princípio da plena concorrência, que representa espécie de dogma no direito tributário internacional. Para a sua concretização, há duas espécies de metodologias distintas: os métodos tradicionais, apoiados na comparação dos preços ou margens brutas de lucro das transações, e os métodos

7. Avaliação do uso de diferentes modelos receptores com dados de PM2,5: balanço químico de massa (BQM) e fatoração de matriz positiva (FMP)
A identificação de fontes para material particulado tem sido um tema de crescente interesse em todo o mundo para auxiliar a gestão da qualidade do ar. Esta classe de estudos é convencionalmente baseada no uso de modelos receptores, que identificam e quantificam as fontes responsáveis a partir da concentração do contaminante no receptor. Existe uma var

8. Particulate matter (PM2.5) concentration and source apportionment in lahore
Neste trabalho foram estudadas as concentrações das PM2.5 (partículas com diâmetro aerodinâmico de 2,5 µm ou menos) e das fontes de incremento das PM2.5, monitoradas numa área urbana residencial de Lahore, Pasquitão. Amostras de PM2.5 em aerosol foram coletadas 2 dias por semana, num inetravlo de 12 h por dia, nas estações seca e húmida, usando um

10. Multi-site PM2.5 and PM2.5-10 aerosol source apportionment in Rio de Janeiro, Brazil
Foi realizada a amostragem de aerossol em dez locais distribuídos em diferentes regiões da cidade do Rio de Janeiro, de setembro/2003 a setembro/2004, em uma base semanal com amostragens de 24 horas. As frações do aerossol PM2.5 e PM2.5-10 foram amostradas usando um sistema com filtros em série. Foram determinadas: a massa do aerossol, carbono elementar

12. AnÃlise multivariada na identificaÃÃo dos fatores determinantes da qualidade da Ãgua na Bacia HidrogrÃfica do Rio Jaibaras-Cearà / Analysis multivariate in the identification of the determinative factores of the quality of the water in the watershed of Rive Jaibaras-CearÃ.
Aiming to identify the apportionment of pollution sources/factors with a view to get better information about the water quality at Jaibaras watershed, a research composed of three steps was developed. In the first step (Step I), it was identified the water pollution sources at the upland of Jaibaras watershed until Ayres de Souza dam. The survey occurred fro
