Two food additives have been found to not be carcinogens but when both are present at low doses in a body, they can work together to open up biochemical pathways that promote cancer.


The pesticide, aluminum phosphide, is stored in large quantities near inhabited buildings even when less than two pounds scattered around a home killed two children with its toxic vapors in 2010.


Arsenic is a soluble, toxic element that can cause cancer. Rice grown in arsenic-contaminated water should be consumed in small amounts to be safe.
