Toxicity testing -- determining the amount of exposure to a chemical that is unsafe for humans -- is vital to the safety of millions of workers in various industries. But of the 85,000 compounds used in consumer products, the majority have not been comprehensively tested for safety. Animal testing, in addition to its ethical concerns, can be too costly and time consuming to meet this need, according to the study published in Environmental Health Perspectives.

"There is an urgent, worldwide need for an accurate, cost-effective and rapid way to test the toxicity of chemicals, in order to ensure the safety of the people who work with them and of the environments in which they are used," said lead researcher Daniel Russo, a doctoral candidate at the Rutgers University-Camden Center for Computational and Integrative Biology. "Animal testing alone cannot meet this need."
