Workshop report on EPA (Environmental Protection Agency) guidelines for carcinogen risk assessment. Held in Virginia Beach, Virginia on January 11-13, 1989

On September 24, 1986, the U.S. Environmental Protection Agency (EPA) issued guidelines for assessing human risk from exposure to environmental carcinogens. Since that time, new information in several areas of carcinogen risk assessment has led to continued EPA review and assessment of the guidelines. As part of the review, on January 11-13, 1989, EPA conducted a workshop at which experts in carcinogen risk assessment examined the scientific foundation for two aspects of the guidelines. Some workshop participants studied qualitative issues bearing on the classification of chemicals as potential human carcinogens; others focused on quantitative questions regarding extrapolation from test animal data to human populations. The workshop report highlights the major scientific issues discussed at the meeting. The report includes remarks by opening session speakers, EPA's pre-meeting statement of issues, summary statements for major workshop discussions, reference lists and a list of workshop, rather than standard scientific papers.
