Introduction to toxicology

An instructor-led online course | November 2022

Learn the principles of toxicology, hazard and risk assessment and toxicological testing

Course details


This online course is divided into four 2-hour training sessions hosted from 10:00-12:00 CET. 

Tuesday 8 November 2022 (10:00-12:00)
Module 1 | Basic toxicology and toxicological terms   
What is toxicology? We will explain the relevance of toxicological knowledge and make you familiar with the most important terms in toxicology. Through examples we will define the dose response concept, including relevant dose metrics, and demonstrate how toxicity depends on exposure routes. We wrap up with an introduction to your homework assignment for module 2.

Friday 11 November 2022 (10:00-12:00)
Module 2 | 
Toxicodynamics and toxicokinetics
Review of the homework assignment. Then we proceed to explain the effects (toxicodynamics) and fate of chemical substances (toxicokinetics) in the body. This also includes a closer look at different types of effects considering  toxicological mechanisms and modes of action (MoA). Brief introduction to homework for module 3.

Wednesday 16 November 2022 (10:00-12:00)
Module 3 | 
Testing and test guidelines
Review of homework task. We then describe the use of animal testing, how to get information and explain test design in the OECD test guidelines for various types of hazard testing and the principles for dose level selection. You will also learn about selection of test species, types of relevant animal examinations and how to apply a tiered approach in testing. We will touch briefly on alternative testing methods before finishing with introduction of your last homework assignment.

Tuesday 22 November 2022 (10:00-12:00)
Module 4 | 
Toxicological risk assessments
We go over the last homework exercise before we describe how toxicology is used in risk assessments. You will learn how to evaluate risks, for instance in connection with accidents and cases of pollution, and through examples we explain how to derive tolerable exposure levels. We also give a short introduction to Threshold of Toxicological Concern (TTC) before we wrap up the course with your final questions.


Poul Bo Larsen has more than 30 years of experience in health risk assessment of chemicals. He has participated in working groups in the EU and the OECD and as the Danish representative in ECHA’s Risk Assessment Committee.

Poul’s comprehensive expertise includes regulatory toxicology, risk assessment, limit values, health impact of ambient air pollution, Occupational Exposure Limits (OEL), nanomaterials and REACH.

Chief Toxicologist

Brian Svend Nielsen has 20 years of professional experience in regulatory toxicology, chemicals regulation compliance and product safety assessment. He has expert knowledge of human toxicology in the areas of hazard identification, exposure assessment and risk assessment of chemicals.
