Quantifying Architectural Painting VOC Air Emissions A Methodology with Estiamtes and Forecasts

摘要

Architectural coatings (referred to as paints), with the thinners/reducers and cleanup solvents used during their application, contain volatile organic compounds (VOCs) which are precursors to ground level ozone formation. Some of these paint compounds create hazardous air pollutants (HAPs) which are toxic. The nationally recommended emission factor (EF) of 4.6 lbs/year per capita is based on data from the 1970s. This paper documents the methodologies and the National Paint & Coatigns Association (NPCA) data sets used to develop revised per capita emissions factors (e.g. 3.5 lbs/year per capita for 1993) for estiamting and forecasting the VOC air emissions from the area source category of architectural coatings. Emissions estimates, forecasts, trends and reasons for these trends are presented. Future emissions inventory (EI) challenges are addressed in light of data a availability, information networks and the proposed category of Architectural and Industrial Maintenance (AIM) coatings.
