Influence of the emissions and substances migrating from the plastics on the sensations of an odor of air and the flavor and odor of water

Abstract

The process of volatile substances emissions from plastics during their processing (injection molding, extrusion) and using in the closed spaces (car interiors, buildings) (Fig. 1) has been characterized on the basis of literature data (including authors' research). There were discussed the most important methods of identification and quantitative determination of odor substances, emitted from virgin plastics as well as (specially) recycled ones, namely gas chromatography (Figs. 2 and 3) "electronic noses" use (Figs. 4 and 5) and olfactometry (Fig. 6). The ways of the emissions limitation e.g. multiple degassing during the recycled products' extrusion (Fig. 7), extraction of eventual pollutants with organic solvent (Fig. 8) or introduction of the additives absorbing the gas substances (Fig. 9) were proposed. The effects of the emitted and migrating substances on the flavor and odor of water delivered using plastic pipes have been treated separately.
