Brown trout in our rivers are in danger of being poisoned by a toxin produced in the watercress farming industry, according to new research at the University of Brighton.

Penethyl isothiocyanate (PEITC) potentially is leaching into water courses and researchers are concerned the toxin can kill trout embryos and cause deformities.

Dr Neil Crooks, from the University’s Centre for Aquatic Environments, who led the research said: “Results show the need to accurately quantify and monitor environmental levels of PEITC in the environment.”

Dr Crooks, with Asa White, a PhD student, and Centre colleagues Dr Angelo Pernetta and Professor Chris Joyce, Professor of Ecology, looked into the sources of PEITC.
