How does household energy consumption contribute to PM10 emissions?

Particle Pollution (PM) is a major problem in urban environments. There is serious health risks associated with exposure to PM. In addition, particulate matter also contributes to greenhouse effects and global warming. PM originates mainly from fuel combustion. In this paper, we attempt to study household energy use contributions to experienced levels of PM concentrations. We find that there is a strong positive association between household gasoline consumption and urban air pollution. Residential natural gas use is also associated with poor air quality.

Manipulação de efluentes de bovinicultura

As crescentes preocupações ambientais para a redução das perdas de azoto em explorações de bovinicultura leiteira impõem o desenvolvimento de métodos de manipulação dos efluentes produzidos. Nesta Dissertação apresenta-se uma revisão bibliográfica sobre os principais processos de tratamento e valorização de efluentes de bovinicultura e um trabalho experimental que teve como objectivos avaliar a utilização dos floculantes PAM e bentonite na remoção de sólidos e nutrientes da fracção líquida do chorume, comparar as emissões de N2O e degradação do N orgânico a partir de chorumes com e sem pré-tratamento após incorporação em solos agrícolas.Após separação mecânica do chorume, foram adicionados à fracção líquida obtida os floculantes PAM e bentonite. A PAM apresentou maior capacidade de remoção de azoto, fósforo e matéria seca na fracção sobrenadante obtida.Também se realizou um ensaio de incubação durante 94 dias, no qual foram medidas as emissões de N2O e o teor de N mineral. Os tratamentos incorporados a solos foram: chorume bruto, fracções sólida e líquida, fracções sedimentada e sobrenadante com PAM. Os processos de pré-tratamento que conduziram à redução das emissões gasosas, relativamente ao chorume bruto, foram: fracção sólida (-25,6%), fracção líquida (-5,1%) e fracção sobrenadante com PAM (-10,3%).

Characterization of the volatile fraction emitted by phloems of four pinus species by solid-phase microextraction and gas chromatography–mass spectrometry

Pine forests constitute some of the most important renewable resources supplying timber, paper and chemical industries, among other functions. Characterization of the volatiles emitted by different Pinus species has proven to be an important tool to decode the process of host tree selection by herbivore insects, some of which cause serious economic damage to pines. Variations in the relative composition of the bouquet of semiochemicals are responsible for the outcome of different biological processes, such as mate finding, egg-laying site recognition and host selection. The volatiles present in phloem samples of four pine species, P. halepensis, P. sylvestris, P. pinaster and P. pinea, were identified and characterized with the aim of finding possible host-plant attractants for native pests, such as the bark beetle Tomicus piniperda. The volatile compounds emitted by phloem samples of pines were extracted by headspace solid-phase micro extraction, using a 2 cm 50/30 mm divinylbenzene/carboxen/polydimethylsiloxane table flex solid-phase microextraction fiber and its contents analyzed by high-resolution gas chromatography, using flame ionization and a non polar and chiral column phases. The components of the volatile fraction emitted by the phloem samples were identified by mass spectrometry using time-of-flight and quadrupole mass analyzers. The estimated relative composition was used to perform a discriminant analysis among pine species, by means of cluster and principal component analysis. It can be concluded that it is possible to discriminate pine species based on the monoterpenes emissions of phloem samples.
