摘要

The paper is an overview of EPA research into controlling sources of indoor air211u001epollution through pollution prevention (P2). The research focused on four 211u001eapproaches for P2: (1) developing methods and tools that can be used by others to 211u001eevaluate emissions from equipment or products; (2) developing generic P2 211u001esolutions to IAQ problems; (3) identifying high-emitting raw materials or 211u001ecomponents of products; and (4) evaluating claimed low-emitting materials. Test 211u001emethod guidelines for measuring emissions from office equipment were developed 211u001eand then evaluated by testing four dry-process copiers in one chamber and 211u001econducting a four-laboratory evaluation using one of the copiers. For aerosol 211u001econsumer products, measurement methods and models were developed that can be used 211u001eto better understand aerosol behavior so that more efficacious and less toxic 211u001eproducts can be developed. As a generic solution for improved IAQ through P2, an 211u001einnovative spray nozzel for use with precharged aerosol containers was developed 211u001eand evaluated. The new design allows for the reformulation of selected aerosol 211u001econsumer products using water and air in place of volatile organic compound 211u001esolvents and hydrocarbon propellants, respectively.
