  • use appropriate analytical techniques to identify and quantify toxins
  • analyse and interpret data from experiments
  • carry out field studies
  • study relevant literature
  • write reports, reviews and papers to share research findings
  • perform risk assessments to determine the likelihood of harmful effects
  • help establish regulations to protect humans, animals and the environment
  • collaborate with other scientific and technical staff 
  • act as an expert witness or give evidence in court.

Key skills and interests

To become a toxicologist, you would need:
