This study highlights the importance of providing psychological interventions for cancer patients and their partners. Chemotherapy patients and those diagnosed over a year, as well as their partners, are more at risk.

EVALUATION OF AROMATIC VOLATILE ORGANIC COMPOUNDS IN THE ATMOSPHERE IN CAMPOS DOS GOYTACAZES AND ITAPERUNA APPLYING MULTIVARIATE DATA ANALYSIS. Volatile Organic Compounds (VOCs) are air pollutants emitted from different sources, mainly by industries and motor vehicles. The evaluation of the emission of these compounds into the atmosphere should be done systematically and with a varied class of compounds. The large number of data generated during the monitoring of these VOCs requires the use of multivariate data tools to interpret the results. In this sense, this work aimed to monitor 10 aromatic VOCs present in the atmosphere of the largest cities in the Norte Fluminense (Campos dos Goytacazes) and Noroeste Fluminense (Itaperuna) regions. The VOCs were actively sampled and analyzed by gas chromatography with mass spectrometry detection after thermal desorption. After treatment of analytical results, it was observed that in both cities there is influence of vehicular emissions. In the city of Itaperuna, due to the relief and lower dispersion of contaminants, there is a higher occurrence of photochemical reactions. The exploratory analysis of the data allowed identifying the variables that were more significant and correlating these variables with the main sources of emission of the compounds. This is the first study of VOCs evaluation in Campos dos Goytacazes and Itaperuna, demonstrating the relevance of this research for understanding the behavior of VOCs in these cities, which have different reliefs and high traffic of cars and trucks in the studied sites.

This study examined the potential for adsorption of methylene blue, in solution of 50 mg.L-1, by banana fiber spray, to 2 g/L of solution. We carried out variations in temperature and pH of the solution. The results indicate that it is possible to use the banana fiber as adsorbent methylene blue in ambient temperature and alkaline pH values with high efficiency. The FT-IR spectrum showed the presence of carboxylic acid and hydroxyl groups on the fiber. Such groups are capable of forming hydrogen bonds with methylene blue and removing it from the aqueous solution. It was concluded that for the conditions tested, the best temperature for adsorption was 25 °C and pH to better efficiency of better temperature was 11.
