Researchers detect toxic chemicals in aquatic organisms with new AI method

The new method developed by the Swedish researchers utilizes artificial intelligence for rapid and cost-effective assessment of chemical toxicity. It can therefore be used to identify at an early phase and help reduce the need for animal testing.

“Our method is able to predict whether a substance is toxic or not based on its chemical structure. It has been developed and refined by analyzing large datasets from laboratory tests performed in the past. The method has thereby been trained to make accurate assessments for previously untested chemicals,” says Mikael Gustavsson, researcher at the Department of Mathematical Sciences at Chalmers University of Technology, and at the Department of Biology and Environmental Sciences at the University of Gothenburg.

“There are currently more than 100,000 chemicals on the market, but only a small part of these have a well-described toxicity towards humans or the environment. To assess the toxicity of all these chemicals using conventional methods, including animal testing, is not practically possible. Here, we see that our method can offer a new alternative,” says Erik Kristiansson, professor at the Department of Mathematical Sciences at Chalmers and at the University of Gothenburg.
