1. IMPACTOS DOS BTEX EM ÁREAS URBANAS DA CIDADE DO RIO DE JANEIRO
Most volatile organic compounds (VOC) have adverse effects on human health and the environment and react individually with different velocities and mechanisms to form ozone. The present work determined the concentration of 55 samples of benzene, toluene, ethylbenzene and xylenes (BTEX), an important subgroup of VOC, by active sampling with active carbon cart

2. CATALYTIC OXIDATION OF ISOPROPYL ALCOHOL OVER PLATINUM BASED CATALYST: A STUDY OF THE EFFECT OF METHYL CELLULOSE ON Pt PARTICLES DISPERSION OVER MULLITE
Abstract Isopropyl alcohol (IPA) catalytic oxidation remains one of the most popular techniques to remove volatile organic compounds from indoor places. In our study, catalytic oxidation of IPA was investigated on catalysts based on platinum deposited on mullite (Al6Si2O13), known for its excellent thermal stability. Pt/Al6Si2O13 catalysts were prepared by i

3. Estudo da copolimerização em mini emulsão de metacrilato de metila/metacrilato de etila / Study of methyl methacrylate/ethyl methacrylate in mini emulsion copolimerization
Reduction of volatile organic compounds (VOC) usage is a constant environmental demand. Polymeric aqueous emulsion of low surfactant contends produced from direct miniemulsion synthesis are used with advantages to replace organic solvents media as well as aqueous emulsions of high surfactant concentration. Water as continuous phase and organic monomers with

4. Tropospheric ozone formation sensitivity to vehicle emission in the Metropolitan Area of São Paulo / Sensibilidade da formação do ozônio troposférico às emissões veiculares na região metropolitana de São Paulo
Este trabalho teve como objetivo avaliar a sensibilidade da formação do ozônio troposférico às emissões veiculares de compostos orgânicos voláteis (COVs) e NOx na Região Metropolitana de São Paulo (RMSP). Essa avaliação foi realizada através de modelagem numérica com modelo de qualidade do ar fotoquímico tridimensional. Para a determinação d

5. Volatile organic compounds, respirable dust, and personal factors related to prevalence and incidence of sick building syndrome in primary schools.
Possible relations between incidence and prevalence of sick building syndrome (SBS), indoor exposures, and personal factors were studied in a four year longitudinal study among personnel (n = 129) in six primary schools. The mean concentration of carbon dioxide was above the recommended value of 0.08 microliter/l (800 ppm) in all schools, indicating a poor o
