There is a need for an assessment of the emission properties of volatile organic compounds (VOCs) from consumer products. A method comparison was carried out to evaluate adapted and cost-effective procedures for such items. Smaller and automated emission chambers de-picted similar kinetics compared to a 203 L standard chamber. Toy samples made of PVC (Polyvinyl chloride) emitted more VOCs compared to other tested polymeric products. The emissions from 2 selected samples were studied to allow an evaluation of the resulting room concentration and external exposure of a child. Obtained concentrations were not of concern.
Wood-based materials are well-known sources for formaldehyde emission in the indoor environment. Different testing standards lead to different emission values for the materials. Such standards are compared in this study. Besides scenarios with varying loading factors, air exchange rates and climatic conditions were investigated to evaluate the formaldehyde emission potential of different building products.
Under realistic indoor conditions used for the emission chamber tests, exceeding of formaldehyde indoor guide values were obtained. Results showed the need for improvement of wood-based materials with lower formaldehyde emissions and the adaption of testing parameters closer to realistic conditions.
