Today, together with researchers at Kings College London, the Universities of Northumbria and Suffolk, and the Francis Crick Institute, AstraZeneca published a paper in Environmental Science and Technology calling for the wider application of machine learning in environmental toxicology research, to reduce the burden on animal testing and better meet the future challenges of scientific discovery. Environmental Protection, together with Access to Healthcare and Ethics and Transparency, is a key priority of the approach to sustainability at AstraZeneca. Our scientific approach to environmental sustainability reduces our environmental impact by protecting our air, land and water, reducing our dependence on natural resources and ensuring the environmental safety of our products. This publication is the result of an ongoing collaboration between AstraZeneca and academic partners, who have been working together to see how machine learning can help us to better understand the impact of chemicals on the environment. Pollution from contaminants continues to be a cause for concern, not only on the environment but also for public health. To understand the effects of this pollution, the research team wanted to look specifically at how chemicals can accumulate in fish and invertebrates.
