Avaliação da qualidade do ar no ambiente laboral: vapores orgânicos nafta e estireno: estudo de caso

Abstract

In this case study was developed to analyze the air in a branch company of fiberglass, which manufactures poles for mains . Are used in making these materials various chemicals derived from aromatic hydrocarbon , volatile characteristics , harmful to the biota and homem. Os chemicals evaluated here were naphtha and styrene , with the line of action performing various collections during the journey trabalho. As collections were carried out in stages and alternate days , so that the results could match the type of collection realidade. O was personal and individual sample , in which the equipment is placed in the breathing zone of the exposed individual to chemical agents . The sampling method was used with a flow of atmospheric air pump with support Sampling activated carbon , using a flow rate of 1L/mea analysis technique used was the Gas Chromatography . collections were performed in the operating sector along the filament machine , the place where the highest concentration was observed poluentes.Com of the results obtained through the analyzes provided by the laboratory and statistical data developed in this study, we make sure the people involved in manipulation of the chemical naphtha and styrene are exposed above the tolerance limit , which according to current legislation and the necessary steps that can be taken to neutralize or minimize contamination of the environment.
