Environmental Management and Toxicology

Dr. E. E. Imarhiagbe

Ag. HOD, Department of Environmental Management and Toxicology


The Senate of the University of Benin, on 3rd July 2013, approved the creation of a new Department of Environmental Management and Toxicology from the existing Part-time Environmental Science Unit established in the 1999/2000 Academic Session in the Faculty of Life Sciences to run a Full-Time programme leading to the award of the Bachelor of Science (B.Sc.) degree in Environmental Management and Toxicology. However, it was not until after the visit of the National Universities Commission (NUC) to ascertain the resources available for its take-off on Thursday, 3rd September 2015 that the Department was granted approval to run the Full-Time programme leading to the award of the Bachelor of Science (B.Sc.) degree in Environmental Management and Toxicology.  The pioneer 100 Level Full-Time students of this diverse and multidisciplinary field of study were admitted in the 2015/2016 academic session.


To develop the human mind to be creative, innovative, research-oriented, competent in areas of specialization, knowledgeable in entrepreneurship and dedicated to service


The philosophy of the programme is the training of Environmental Managers and Toxicologists to the highest scientific and research standard in the identification and resolution of environmental issues such as pollution control, waste management, environmental biotechnology and toxicology. The programme is a specialized multi-disciplinary one executed through four different units as follows:

  • Aquatic/Terrestrial Toxicology,
  • Genetic/Molecular Toxicology,
  • Environmental Chemistry, and
  • Environmental Management


In line with the institutional mission, the programme provides students with a broad and balanced foundation of Environmental Management and Toxicology and practical skills in the areas of management of institutional, industrial, research laboratories and workshops to meet local and international environmental needs. Given the constant environmental degradation in the country, the programme is relevant to national needs in training graduates to understand the ecosystem to promote and advocate sustainability of the environment for future development of the country.


The programme will provide skilled manpower, trained specifically for environmental surveillance, monitoring and management.

The specific objectives are:

  • to provide students with a broad and balanced foundation of scientific knowledge and practical skills in the areas of sustainable management of the environmental needs of the country and the international community
  • to produce skilled manpower to meet specific needs on the environment. These needs include the ability to initiate novel ideas for the transformation, resuscitation and sustainable management of contaminated environments
  • for the training and deployment of employable and entrepreneurial graduates to create genuine career opportunities with a wide range of organisations such as water authorities, research institutes, conservation bodies, businesses, local authorities, government and private agencies.


  • UTME: Candidates who have successfully completed the senior secondary school or its equivalent and obtained five credits in Mathematics, English Language, Chemistry, Geography and Biology or Agricultural Science, in not more than two sittings and candidates must also have at least a pass in Physics. Candidates must score the minimum cut-off points specified by JAMB and also passed the post UTME examination of the University of Benin. The UTME subjects are: English, Chemistry, Biology and either Mathematics, Geography or Physics.
  • Direct Entry: Candidates who fulfill the above requirements and who have obtained G.C.E Advanced Level, H.S.C. or equivalent passes in Biology and Chemistry, may be admitted at the 200 level of the programme. Also, candidates having:
  • At least a credit level pass in the University of Benin Diploma in any of the following:
  • Food and Brewing Science (DFBS)
  • Applied Microbiology (DAM)
  • Science Laboratory Technology (DSLT)
  • Geology (DIG)
  • Analytical and Industrial Chemistry (DAIC)
  • Diploma in related areas from other recognized Universities with at least an Upper   credit level pass in the areas listed in (a) above.
  • Ordinary National Diploma (OND) with at least a credit level pass in Science Laboratory Technology (SLT), Food Technology, Polymer Chemistry,  Geology/Mining or other related subject area from a recognized polytechnic or College of Technology.


For candidates who join the programme at 100 level, they are expected to register and pass a minimum of 160 credit units, for those joining at 200 level, they are expected to register and pass minimum of 130 credit units; while  for those joining at 300 level, they are expected to register and pass minimum of 100 credit units. In other words, 30 credits from each level courses as application and in addition, 10 credit units of General Studies mandatory courses which are not used in calculating the G.P.A.

Students on Probation

Probation is a status granted to a student when he/she did not earn the minimum number of credits needed to qualify him/her to move to the next higher level but earned not less than 50% of the minimum number of credits.

Students to Withdraw

  • A student who did not earn the minimum number of credits needed to qualify him/her to move to the next higher level and also earned less than 50% of the minimum number of credits is to withdraw from the Faculty and University
  • A student who was previously on probation and did not earn the minimum number of credits needed to qualify him/her to move to the next higher level during the year of probation but earned not less than 50% of the minimum number of credits is to withdraw from the Faculty and University. In other words, this applies to a student who is probating the second time.

Repeating Failed Course Unit(s)

Subject to the conditions for withdrawal and probation, a student may be allowed to repeat the failed course Unit(s) at the next available opportunity, provided that the total number of credit units carried during that semester does not exceed the minimum specified in the guidelines, and the Grade Points earned at all attempts shall count towards the CGPA.

Course Credit Unit System

This should be understood to mean a `quantitative system of organization of the curriculum in which subject areas are broken down into unit courses which are examinable and for which students earn credit(s) if passed’. The courses are arranged in progressive order of difficulty or in levels of academic progress, e.g. 100 Level or first year courses are 101, 102, 103 e.t.c., and 200 Level or second courses are 201, 202, 203 etc. The second aspect of the system is that courses are assigned weights referred to as Credit Units (indicating the number of credit units allocated for Lectures, Practical or Tutorials).

Grade Point Average (GPA) and Cumulative Grade Point Average (CGPA)

Performance in any semester is reported in Grade Point Average. This is the average of weighted grade points earned in the courses taken during the semester. The Grade Point Average is obtained by multiplying the Grade Point Average in each course by the number of Credit Units assigned to that course, and then summing these up and dividing by the total number of Credit Units taken for the semester.

This is the up-to-date mean of the Grade Points earned by the students in a programme of study. It is an indication of the student’s overall performance at any point in the training programme. To compute the Cumulative Grade Point Average, the total of Grade Points multiplied by the respective Credit Units for all the semesters are added and then divided by the total number of Credit Units for all courses registered by the student.


Techniques of Students Assessment

Students would be examined by one or a combination of the following methods: Tests.Laboratory Practicals, Home Work Assignments for courses with practical components and Semester Examinations. The weights to be attached to these examinations are determined by the University. However, there are courses that are to be assessed fully (100%) through practicals/and or exercises.

 Qualifications to sit for Semester Examination

Attendance to all lectures and practical classes is compulsory. A student must make a minimum of 75% attendance in lectures in to qualify to sit for the paper to be examined. A staff is expected to take attendance in all lectures and should compile the list of students who do not meet the required 75% attendance to be sanctioned to sit for the said paper unless he/she has an acceptable reason such as illness etc. that is acceptable to the University. However, a check on the lecturers should also be made to ensure they are discharging their moral and academic duties. A standard lecture attendance sheet should be served by a lecturer during each lecture or practical class for students to append their signatures.

Continuous Assessment (CA)

This is the general students’ evaluation for a course he/she registered. A student who does not have a CA score automatically fails the course irrespective of what he/she scores in the semester examinations. Where a student missed a CA for genuine reason/s, he/she would be allowed to make-up for it.

External Examiner System

External Examiners should be used only in the final year of the undergraduate programme to assess final year courses and projects, and to certify the overall performance of the graduating students as well as the quality of facilities and teaching.

SIWES Rating and Assessment (Industrial Attachment) All students taking any degree in the sciences must undergo a minimum of six months Industrial Training with a minimum of 6 credits. Students should be assessed using the Log Book, a Report and Seminar.
