The following note was transcribed using OCR from materials presented
at the “Forum on Undergraduate Toxicology Coursework” held February 22, 1992,
in Seattle, WA, as a satellite to the annual meeting of the Society of
Toxicology.
A Symposium and Workshop on Toxicology Training,
organized by NIEHS, was held in Raleigh, North Carolina, February 28-30, 1980
and a Report was published a year later (Veterinary and Human Toxicology 23,
1981). The section “Some Special
Toxicology Education and Training Programs” was prepared and represented the
status and promise of those programs at that time. Tabulated data concerning curricula and
post-baccalaureate activities of graduates lead to the conclusion that the
science education and training within these programs is virtually identical to
that in a myriad of fields at those or similar institutions. There is a need for a similar survey in the
1990s.

SOME SPECIAL TOXICOLOGY
EDUCATION
AND TRAINING PROGRAMS

Toxicology has concurrently enjoyed and endured a
recent burst of growth resulting from increased dialogue about health and
environmental effects of chemical-based technologies. The responses of academic, industrial,
regulatory, and public sectors to new information about the biological effects
of excessive amounts of chemicals have varied considerably. Students at all levels of advanced study have
perceived new opportunities for service and security in toxicology. This report is about some academic responses
to the present climate in universities and colleges. The forum provided by NIEHS provided an
opportunity for educators who are developing "special programs" to
discuss many important issues in toxicology education and training.
Many toxicologists have taken an armslength, or
even negative, attitude toward development of baccalaureate and other special
programs in toxicology. In times during
which the disciplinary and professional needs of toxicologists are frequently
the subjects of concern, it is somewhat surprising, and occasionally
discouraging, that many individuals have resisted innovation in education and
training in toxicology. Improving the
quality of these and other similar programs will require the continued
attention of persons in all sectors (academia, industry, government, public).
Biochemistry, nutrition, physiology, genetics and a
list of many well-established “economic zoologies” (entomology, plant
pathology, nematology) are contemporary academic programs which have been
developed from more basic areas of study, ie physics, chemistry, and
biology. Careful examination of the
nature and scope of baccalaureate and other special programs will reveal that
they are very similar to these college and university programs. Their emergence onto the academic scene is
more the product of student interest in educational alternatives and faculty
commitments to teaching than it is the result of doomsday projections about the
disparity between demands (usually unspecified) for trained personnel and
existing numbers of qualified toxicologists.
It is important to note that discussions of special
programs at the Raleigh meetings were by no means comprehensive in their
coverage. Education and training
activities in forensic toxicology, occupational medicine and toxicology, and
clinical toxicology unfortunately were not included. Sharply increased numbers of continuing
education alternatives including numerous conferences, workshops, and short
courses warrant consideration and evaluation.
Some of these could be classed as special programs in continuing
education (Gibson, Vet Human Toxicol, 21: 180, 1979). Valuable knowledge of education and training
alternatives would likely result from future meetings such as this Symposium
and Workshop on Toxicology Education and Training.
Participating in the discussions from which this
report was derived were Drs David Brown and Jeffrey Blumberg of Northeastern
University, Dr Gary Lage of the Philadelphia College of Pharmacy and Science,
Dr Jean Scholler of the University of San Francisco, Dr James Seiber of the
University of California, Davis, Dr I Glenn Sipes of the University of Arizona,
and Dr Robert Snyder of Thomas Jefferson University. Each of these persons provided written
descriptions of their respective programs which have been liberally
plagiarized. The author accepts

Bachelor of Science: University of California, Davis', Noriheastern
University; Philadelphia College of Pharmacy and Science.
Baccalaureate programs in toxicology are relatively
recent additions to the academic scene.
Schools of pharmacy at Northeastern University and the Philadelphia
College of Pharmacy and Science have recently implemented programs similar to
program
initiated in 1968 at St John's University. The Department of Environmental Toxicology in
the College of Agricultural and Environmental Sciences at Davis intro-duced a
baccalaureate degree in Environmental Toxicology in 1975.
The programs at Northeastern, Philadelphia, and
Davis share the common goal of providing undergraduate education and training
in toxicology. The programs are the
products of their unique academic environments.
Each has particular distinguishing characteristics which here can only
be briefly reviewed. More detailed
descriptions can be obtained from the respective college catalogues and from an
Appendix to this report which is available from NIEHS.
Students who elect Environmental Toxicology at
Davis, select the major from a list of 42 options from Agrarian Studies to
Zoology and including a virtually unrestricted category Individual Major. Whether or not the proliferation of academic
majors is viewed as desirable or not, the tendency of faculty to form special
education programs results in a large number of disciplinary options for
baccalaureate study. The baccalaureate
toxicology programs of the 3 institutions represented at the Workshop offer
contemporary curricula which verv closely resemble degree programs in other
sciences such as chemistry, biological science, zoology, physiology. Baccalaureate studies in toxicology directed
by professionals are simply one of the newer options.
The concern that baccalaureate programs in
toxicology will weaken undergraduate education and training is not supported by
study of existing curricula (Table 1). For convenience, coursework in 4 institutions
which offer baccalaureate degrees has been listed by semester credit unit. Courses have been classified as preparatory
subject matter and depth subject matter.
In every case the preparatory subject matter is equivalent to that
required of other "hard science" majors. Depth (or"pre-professional"
coursework) subject matter includes upper division courses in toxicology and
related disciplines. Similarities
between the curricula are immediately obvious by examination of Table 1.
Qualitative differences among graduates are to be expected on the bases of
differing student aptitudes and interests as well as of intrinsic
characteristics of parent academic institutions.
Both Northeastern and
(Degrees are awarded after 5 years of
study) The industrial traineeship requirement
at Philadelphia is scheduled for an 8-month interval between the third and
fourth years of study. Goals of the
Philadelphia traineeship program are similar to those of Northeastern. About half of the students at Davis
participate on an elective basis in research or other activities in toxicology
to obtain work experience. It is also possible for students to obtain academic
credit on an elective basis in toxicology-related part-time positions at
Davis. These examples illustrate that
faculty have clearly recognized that importance of providing students
opportunities for pre-professional training experience as part of their
undergraduate studies.
Following discussion of the
characteristics of existing programs, participants in the special programs work
group listed several requisite features of programs for adequate baccalaureate
education and training in toxicology.
They included the following: Professional faculty committed to
excellence in teaching and research in toxicology; Coursework in toxicology and
related disciplines including chemistry, biology, biochemistry, pharmacology,
pathology, and physiology; Laboratory facilities to accommodate analytical and
biological coursework (including AAALAC approved animal quarters); and
Opportunity for pre-professional experience in governmental, industrial and
academic settings.
Among the positive impacts of such
programs will be a strong identity of toxicology to the University community
students, faculty, staff and administrators.
General course's in toxicology will be used as electives in other
undergraduate and graduate programs. A
successful course for science and non-science students at Davis has been
described (Krieger et al, Vet Human Toxicol 21:352, 1979). As the discipline of toxicology is
increasingly associated at all level with decision-making about chemical
technologies, the mere presence of strong undergraduate teaching programs
represents an opportunity for the sorely needed infusion of toxicology into the
academic experience of the educated public.
An additional indirect impact is that
the existence of a degree-generating program is critical in the quest for
enrollment, new faculty, and resources within colleges and universities. The possibility that the enrollment of the
Philadelphia program will constitute 10-20% of the total undergraduate student
body potentially represents a profound institutional impact of baccalaureate
toxicology. To a lesser extent growth in
the Department of Environmental Toxicology at Davis has occurred as a
consequence of a recently expanded curriculum which now offers both graduate
and undergraduate instruction. Further
immediate expansion and maturation of education and training programs during
the 1980s will occur during times of fiscal austerity and steadytate
enrollments in colleges and universities.
These new options in undergraduate instruction seem to have a strong
potential for fiscal and programmatic growth.
Representatives of each of the
institutions stressed that the BS programs are attracting the interest of
talented, service-oriented students. Two
surveys of Davis undergraduates have been conducted to ascertain their
post-graduation plans. Each student was
asked to list their immediate objective and to rank their first, second, and
third options. In both 1978 and 1980
most persons planned to pursue additional education and training including
graduate studies in toxicology (Table 2). This situation closely parallels experience
in the College of Agricultural and Environmental Sciences where about 65% of
graduates pursue additional education and training within 5 years of the award
of their BS degrees. Respondents were
about equally divided in their preference of either industrial or governmental
work. Limited availability of job
descriptions for entry level positions in toxicology no doubt contributes to
student uncertainty about opportunities in the industrial, governmental, and
academic sectors.
There is a close similarity between student
aspirations and activities of recent graduates of the
Master of Science:
A Master of Science Program in
Toxicology was started at the University of Arizona in the spring of 1973. Administratively, it is a free-standing MS
program which initially functioned under the direction of the Coordinator of
Interdisciplinary Programs. A Toxicology
Program Committee composed primarily of members from the Departments of
Chemistry, Biochemistry, Internal Medicine, Pharmacology, Pathology, Cell
Biology, Entomology as well as members of the University Analytical Center and
the College of Nursing was established to oversee the direction and progress of
the Program. The makeup of this
Committee insured that toxicology would be a campuswide program with a truly
interdisciplinary nature. Recently, the
administration of the Toxicology Program was moved to the College of
Pharmacy. However, the campus-wide
Toxicology Program Committee was retained to decide on such matters as
curriculum and the overall direction of the Toxicology Program.
Overall goals of our program leading
to a Master of Science degree in Toxicology are to train students with a strong
laboratory experience, a broad overview of toxicology and a realistic approach
to problem solving. These goals are
partly accomplished by providing instruction in the basic disciplines closely
associated with toxicology. These
include biochemistry, physiology, pharmacology and pathology. The courses in physiology and pathology both
include laboratory. In addition,
students are provided with courses that emphasize both general and specialized
areas of toxicology. Laboratory
experience in toxicology is emphasized in two courses: Analytical Toxicology
and Biotoxicology. Analytical Toxicology
trains students in various separation techniques and in instrumentation. Biotoxicology laboratory provides
instructions on the use of laboratory animals in assessing toxicologidal
problems. A laboratory research thesis
is required so the student will have an in-depth knowledge in one area of
-oxicology and to assure that the program is training individuals who could
function independently in a toxicology laboratory. By proper selection of electives and a
research problem, students can specialize in such areas as Industrial,
Agricultural, Environmental and Analytical Toxicology.
When the program began in 1973, 4
students were enrolled. By the beginning
of 1980, 35 students were enrolled as full-time Masters candidates in
Toxicology. By the end of 1980 the
program will have awarded degrees to 46 students. From an applicant pool of approximately 100,
10 to 12 new students are selected each year for this popular program. In addition to its own students, the Toxicology
Program offers instruction to students from Pharmacology, Biochemistry,
Pharmaceutical Sciences, Nutrition, Entomology, Safety Management, and
Nursing. Several of these students are
PhD candidates who have elected to minor in toxicology.
In addition to providing education in
toxicology at the
Because of the success of the Masters
Program and because of student demand, a PhD program in Toxicology has recently
been established. This program operates
jointly from the Toxicology Program and the Departments of Pharmacology in the
Colleges of Medicine and Pharmacy. At
present seven students are enrolled in this program, five of whom are
specializing in Environmental Toxicology.
Students awarded the Masters degree
have found employment in a variety of areas.
Of the 46 degrees awarded to date, 15 students are employed for
industrial concerns, 14 students are enrolled in or have graduated from MD or
PhD programs, 9 students are working in university of hospital laboratories, 2
students are working for federal agencies, and 2 students are enrolled in or
graduated with MS degrees in Safety Management.
The remaining students have accepted positions unrelated to toxicology.
Master of Toxicological Sciences:
A Master of Toxicological Sciences
Program has been developed at the
Fundamentals of toxicology and a
survey knowledge in several areas of specialization are presented. The student may pursue one of two options --
an emphasis in regulatory affairs or in applied toxicology. Students are required to make this choice by
the end of the first semester. In
addition, each student develops an in-depth knowledge of the specialty related
to the thesis topic. The thesis may be
either a literature review of the toxicology of an agent or class of compounds
or a report of original research. In the
latter case it is assumed that facilities of the students' employers will be
utilized since limited University facilities are available. Completion of the thesis and passing a
comprehensive examination are required of the degree candidates. The program is particularly interesting and
important to individuals with several different backgrounds: persons in public
health positions who desire to increase their knowledge of toxicology so that
they may communicate more effectively with others on the health team;
laboratory technicians who have considerable on-the-job training and experience
who wish to strengthen their academic background to open the possibilities for
broader careers in the laboratory or in product safety/liability or in
regulatory affairs; persons desiring mid-career changes who have a strong
background in the biological/chemical sciences constitute the other easily
identified candidates. Each of these
groups bring particular aptitudes and needs to the program, and presently 70
students are enrolled.
Instruction and guidance at the
Post-doctoral Master of Science:
A special 2-year, post-doctoral
training program in toxicology leads to a Master of Science degree at
Because of research projects and
training in toxicology being conducted by members of the Department of
Pharmacology and other departments within the University, faculty are in
frequent communication with directors or administrators of industrial or
toxicology programs and employment agencies who are eager to employ recent
graduates or who ask for consultation and help with their problems. Neither this institution nor other toxicology
training centers can adequately meet the needs of industry and government at
our current training levels. Thus,
people are being hired who possess PhD degrees in a variety of scientific
disciplines and then receive some degree of on-the-job training in toxicology. This form of training is of a patchwork nature
at best and cannot substitute for rigorous training in toxicology.
The goal of the training program is
to meet both the short- and long-term requirements in the training of
toxicologists by expanding our existing PhD program to train post-doctoral fellows
who can actively and efficiently become engaged in toxicological work.
The MS program includes formal course
work, participation in toxicology research, and a working rotating internship
in laboratories which perform research and service work in industrial
toxicology, a laboratory devoted to toxicity testing on a contract basis, a
bioanalytical and forensic toxicology laboratory, and a company in which a
toxicologist will present regulatory problems relating to employee and
environmental health. This experience
aids the fellow in selecting the specific branch of toxicology in which to
work. Thus fellows may elect to work as
toxicologists for specific chemical companies which operate their own
toxicology laboratories in which toxicologists are concerned with designing and
performing toxicity studies.
Alternatively the companies may contract toxicity testing to commerical
laboratories. In the latter event
toxicologists will be required to make judgments of the quality of testing labs
and their competence before assigning projects.
The students are prepared to design experiments, interpret results, and
make recommendations to their companies based upon test results. Additionally emphasis is placed upon the role
of the toxicologist in assisting in decisionmaking relating to regulatory
affairs and environmental impacts of chemical technologies. The training program basically consists of
three phases.
The first phase is a series of required and
elective courses that are currently given to medical or graduate students. In some cases the courses have been initiated
and given preferentially to the post-doctoral group. The required basic course work consists of 22
credits and the elective course work consists of 8 credits. The second phase of study provides an
opportunity for the fellows to observe and to discuss with faculty members
ongoing research projects in toxicology and related areas such as teratology or
carcinogenesis. The postdoctoral fellows
also are required to visit an industrial laboratory, a contract testing
laboratory, a commercial analytical forensic laboratory, and an industrial and
environmental toxicology group. These
short-term visits (about 2 weeks) are designed to acquaint the students with day-to-day
activities of professionals.
Finally the third phase of training consists of a
research project conducted with supervision of participating faculty. This work provides the student an in-depth
knowledge of one field of toxicological research related to other areas of
occupational and environmental toxicology.
Since the candidates have proficiency in research they can be readily
introduced into toxicological research with its particular problems and thought
processes. For instance, problems
currently under study are benzene toxicity, pesticide-carcinogen interactions
heavy metal-membrane interactions, effects of stress on carcinogenesis, toxic
effects of drugs on bone marrow, mass spectrometric analysis of metabolites of
chemicals, behavioral toxicology, biochemical toxicology, teratology, and
chemical events preceding chemically induced birth defects.
A written report of the research project is
required and serves as the basis of an oral examination in toxicology before a
panel of faculty members. Successful
candidates will be awarded the degree of Master of Science in Industrial and
Environmental Toxicology.
Conclusion
Considerable attention of professionals in
toxicology has been directed toward identification of toxicology as a discipline
and to development of a consensus about the characteristics of adequate
education and training. Both the 1965
Education Committee Report to the Society of Toxicology and a 1974 paper
"Graduate Training in Toxicology" (Plaa, 1974) concluded as follows:
"Toxicology and the training of toxicologists is changing. Our training at this stage seems to be
centered along traditional lines. What
we need to do is to critically examine our programs and not be reluctant to
exploit newer, unconventional approaches." Plaa continued, "This
Summation written in 1965 is still applicable in 1973." Although intended
to describe graduate training, Plaa's comments effectively describe some of the
present responses of educators which have been discussed in this forum on
Special Programs. Development of
improved means to meet student needs for education and training in toxicology
warrant careful consideration and continued support of professionals in
academia, industry and government.
