The third factor was the attendance of nine well-known carbon scientists from Europe and Japan in the 1984 symposium. Support for their attendance was obtained by a grant from The Petroleum Research Fund supplemented by contributions from the following industrial sponsors Aluminum Company of America, Ashland Petroleum Company, Arco Petroleum Products Company, Exxon Research Development Laboratories, GA Technologies Inc., Gulf Canada, Ltd., Gulf Research Development Company, Koppers Company, Inc., Mobil Oil Corporation, The Standard Oil Company (Ohio), and UOP, Inc. 

Summary 99% Nitric acid can be prepared from 70% nitric acid or ary other lower concentration of nitric acid by adding the nitric acid to excess sulfuric acid, and then extracting with methylene chloride. The upper methylene chloride layer is recovered, and then carefully distilled at 40 Celsius to remove the methylene chloride and recover the 99% nitric acid.

Coal Tar Products. No studies were located regarding developmental effects in humans or animals following inhalation exposure to coal tar pitch or coal tar pitch volatiles. As cited above, a site surveillance program conducted by the Texas Department of Health beginning in 1990 at a housing development in Texarkana, Texas, that had been built on part of an abandoned Koppers Company, Inc., creosote wood treatment plant on soil contaminated with creosote revealed no adverse developmental... 

At the Koppers Company, Inc. NPL site in Texarkana, Texas, where a creosote wood treatment facility existed for 51 years prior to being converted to a residential area and an industrial site (sand and gravel company), creosote-derived naphthalene, acenaphthene, fluorene, pyrene, and phenanthrene were measured in ground water at levels ranging from nondetectable to 105 ppb (Agency for Toxic Substances and Disease Registry 1994). Surface water at the site had no detectable levels of the acid or base/neutral compounds that were monitored.

In sediment samples from a creek adjacent to the Koppers Company, Inc. NPL site, creosote-derived base/neutral compounds were detected at concentrations up to 100 ppm one creosote-derived base/neutral compound was detected in downstream sediment at a maximum of 1 ppm (Agency for Toxic Substances and Disease Registry 1994). Creosote-derived base/neutral compounds were also detected in the sediment of the drainage ditch at the site, at levels ranging from 1-100 ppm. 

Data were not available in the literature on the dietary exposure of creosote to children. Based on the bioaccumulation of creosote constituents in fish and other aquatic organisms, and the potential for uptake or contamination in plant food sources, dietary exposure is theoretically possible, but is unlikely to be significant. An exception to this may be in residential areas such as that built on the old Koppers Company, Inc. site. Homegrown produce grown in contaminated soils may provide a significant source of exposure to children. The drinking of chaparral tea may result in oral exposure to wood creosote.
