Screening emission analysis of construction materials and evaluation of airborne pollutants in newly constructed display cases

Emissions of materials currently used for constructing show cases have been studied by means of thermal extraction. The most abundant compounds in the broad spectrum of identified substances were n-butyl acetate, ethoxypropylacetate, 1-methoxy-2-propylacetate and ethyl-3-ethoxypropionate. These are used as solvents and additives in coating and adhesive formulations. Additionally, ketoximes, cross-linking agents in neutral curing silicones, were conspicuous compounds. Materials, whose emissions cause adverse health effects, were detected and should be used with caution.
