1. Câmara de Topo Aberto, CTA: construção e uso para observação de potencial tóxico da poluição atmosférica urbana com bioensaios em plantas / Open Top Chamber : erection and use for toxicological evaluation of urban air pollution using plants bioassay
A Câmara de Topo Aberto, CTA, foi adaptada para gerar um gradiente da concentração da poluição atmosférica ambiente por material particulado fino, capaz de ser utilizado em experimentos toxicológicos. Uma vez que os aerossóis urbanos são composições quimicamente complexas, com comprovada toxicidade na saúde e mecanismos de ação sobre o homem ai

2. Estudo bioquimico e da estrutura foliar de plantulas do jatoba da mata (Hymenaea courbaril L.) e do cerrado (Hymenaea stigonocarpa Mart.) expostas a concentração elevada de C O IND. 2 / Structural and biochemical study of leaves of jatobas Hymenaea coutbaril L. and H. stigonocarpa Mart. exposed to elevated concentrations of carbon dioxide atmosphere
The atmospheric concentration of carbon dioxide (CO2) increased from 280 ppm, during the Industrial Revolution period, to about 370 ppm in the nowadays. It is continuing to increase about 1.8 ppm per year. The effect of this rise in CO2, which is leading to global warming have attracted considerable attention, generating reports on how these changes can affe

3. Microbial Consumption of Atmospheric Isoprene in a Temperate Forest Soil
Isoprene (2-methyl-1,3 butadiene) is a low-molecular-weight hydrocarbon emitted in large quantities to the atmosphere by vegetation and plays a large role in regulating atmospheric chemistry. Until now, the atmosphere has been considered the only significant sink for isoprene. However, in this study we performed both in situ and in vitro experiments with soi
