Toxicology Information Center


The Toxicology Information Center (TIC) provides a vital outreach function to citizens and professionals by responding to their inquiries about the potential hazards from exposure to chemicals and other agents encountered in the workplace, home and other environments. The TIC provides up-to-date, unbiased information in a form that is understandable and useful to the caller. Individuals who have questions about chemical or other exposures, occupational safety and other issues can call or email the TIC director at the number/email listed at right.

The TIC also houses a small library of research journals, reference books, current scientific data on occupational and environmental chemicals, and health and safety advisories. The center's printed collection highlights industrial, occupational, environmental, and epidemiological research publications, as well as a core group of basic science journals. These are also available electronically through the Center's computer systems. Members of the public can peruse the publications in our collections, make copies of pertinent materials, and perform computer searches of  MEDLINE and many other databases using the Center's computers.

Dr. Fred Berman is the TIC Director. He also serves as consultant to the Oregon Department of Agriculture's Pesticide Analytical and Response Center (PARC), which is legislatively mandated to address pesticide-related incidents in Oregon that have suspected health or environmental effects, and is a co-investigator with the National Pesticide Information Center (NPIC), a U.S. Environmental Protection Agency-sponsored project operated cooperatively with Oregon State University. NPIC provides objective, science-based information about pesticides and pesticide-related topics to enable people to make informed decisions about pesticides and their use.

Indoor Air Quality

Poor indoor air quality (IAQ) is frequently an issue brought to the TIC. It has profound adverse effects on worker health, morale and productivity and should be addressed as soon as it becomes an issue. Recently, an owner of a business began experiencing respiratory symptoms whenever he entered his building. He reported that there had been no changes to the building’s interior, such as new carpeting, furniture, or remodeling activities. Nor had there been any adverse events, such as water leaks, which could create a problem with mold growth. He did not know whether there had been any changes to the building’s ventilation system or whether the heating system had been recently serviced.

In the situation described, the caller had wisely sought medical help and learned that tests of his pulmonary function were abnormal. The tentative diagnosis was occupational lung disease, which can include allergic sensitivity to airborne agents such as dusts, molds and volatile chemicals. If unresolved, chronic exposure to pulmonary-sensitizing substances can result in permanent lung damage. In this case, it was suspected that the inciting agent was dust from fabrics stored in his business; however, a proper IAQ evaluation would be necessary to reveal the true nature of the problem. It was advised that he seek the help of an industrial hygienist, since proper determination of a variety of air quality factors would provide a clearer picture of the problem and its possible solution. Moreover, consultation with an occupational physician, who could provide guidance on reducing or eliminating the health hazard, was also discussed.



A caller who lives adjacent to an agricultural field is concerned about pesticide applications that may be drifting onto his property and endangering livestock as well as contaminating his vegetable gardens. He had, in the past, experienced damage to trees and other vegetation, as well as contamination of livestock, due to pesticide drift from that agricultural operation. In that instance, the Oregon Department of Agriculture's Pesticides Division was able to document that drift had occurred and issued citations to the pesticide applicator. The land owner is concerned that similar inappropriate applications of pesticides may be occurring, and that his health, as well as the health of his neighbors may be in danger.

In instances where it is believed that pesticide use or misuse is causing adverse health or environmental impacts, we advise callers to contact the Oregon Department of Agriculture's (ODA) Pesticides Division. The ODA has the investigative authority for pesticide incidents in Oregon. The Pesticides Division houses  the Pesticide Analytical and Response Center (PARC), whose mandate is to:

  • Collect incident information
  • Mobilize expertise for investigations
  • Identify trends and patterns of problems
  • Make policy or other recommendations for action
  • Report results of investigations
  • Prepare activity reports for each legislative session

Although the PARC board has no regulatory authority, it's primary function is to coordinate investigations by the appropriate member agencies (OR OSHA, DEQ, Oregon Health Authority, Dept. of Forestry, ODOT, Poison Center, ODFW, State Fire Marshal) and to collect and analyze information about reported incidents (

In this instance, the landowner had worked with ODA in the earlier incident. He was encouraged to continue his contacts with the Pesticides Division and to document his concerns with photographs, if possible, in order to aid investigators' determination as to whether pesticide violations had occurred. He was also advised to contact the National Pesticide Information Center (NPIC) for information about the specific pesticides being used near his property. NPIC ( provides objective, science-based information about pesticides and pesticide-related topics to enable people to make informed decisions about pesticides and their use. NPIC is a cooperative agreement between Oregon State University and the U.S. Environmental Protection Agency.
