The Human Toxome Project (HTP) is working to understand the scope of industrial pollution in the
human body. Industrial chemicals may enter the body through pollution or as ingredients in consumer
products. In October 2008, the scientists at HTP tested cord blood samples for 20 newborn infants in the

how many of the targeted chemicals were found in each infant's cord blood. Based on the sample data,
