Dr Lang Tran
Head of Toxicology Section – Principal Toxicologist
Institute of Occupational Medicine
The UK Department for International Development (DfID) commissioned the Institute of Occupational Medicine to conduct toxicological tests to determine the relative safety of the Montserrat volcanic ash. These included an inhalation experiment conducted in rats by IOM. This experiment was designed by Dr Lang Tran with the objective of testing the null hypothesis that, dose for dose, inhaled volcanic ash causes no greater pulmonary inflammation than a benchmark, low toxicity, control dust.
