INTRODUCTION AND OBJECTIVES This report covers the work performed on the exhaust emission of polynuclear aromatic hydrocarbons (PNA) and phenols under CRC-APRAC Project CAPE-6-68 in the third year of the Project. Government (Environmental Protection Agency) support (33% of total cost) has been previously provided under Contracts CPA-22-69-56 and CPA-70-104 and is currently provided under Contract 68-04-0025. While the present work extends past work@ a time-gap occurred between the end of the second year in February@ 1971@ and resumption of contract work on May 6@ 1971. During this delay period@ several PNA/phenol tests were carried out at the expense of Esso Research and Engineering Company. These Esso tests are described here to the extent that they may affect subsequent contract tests or are essential for data interpretation. To some extent@ these tests were in line with contract plans; in any case@ they were valuable for maintaining test personnel and test capability during the renewal-negotiation period.
