...with objective and scientifically-sound criteria.

A clear prioritization tool can help EPA evaluate chemicals more efficiently and effectively.

Individual criteria used to determine a chemical’s ranking

EXPOSURE FACTOR Other factors such as whether it is formulated in children’s products or detected in biomonitoring programs EXPOSURE FACTOR Whether it persists or accumulates in the body
