In a first phase a review on the current state of the art of consumer product emissions in general (i.e. product compositions, emission test protocols, emissions, secondary reactions and exposure) provides to the base of BUMAC. A set of 15 product classes is then selected for further research, applying selection criteria. To meet these criteria, the products of a class should (1) be used in households, (2) cause an exposure related to the use (3) emit key or emerging pollutants (4) have a considerable indicative household use frequency (5) mainly cause inhalation exposure and (6) cause a health end point. The following product classes might be selected: personal care products, air fresheners, cleaning agents, sprays, cigarettes.
Secondly, a market study on the use, use pattern, habits and attitudes of EU consumers for the selected product classes leads to the identification of representative, European region specific, information on the frequency and quantity of use, types, packaging and market share of different products. The experimental laboratory work focuses on the identified research gaps.
In the next phase, the quantified emission data for key and emerging pollutants (literature and experiments), based on the typical use of the products, are applied in exposure and health risk assessment models. The contribution of inhalation exposure is evaluated in relation to the overall exposure.
As a result, data gaps in BUMAC are completed, an efficient risk management guidance is developed, and policy options are formulated. Several exposure reduction strategies are considered, including advices on policies, guidelines and procedures to quantify emissions of consumer products and their risk assessment.
These outcomes will provide applicable tools to reduce the risk associated to the indoor use of consumer products and will lead to a healthier indoor environment for citizens.
