about this participant:

Davis Baltz, a research associate from Berkeley, CA, participated in the 2003 biomonitoring investigation entitled "EWG/Commonweal Study #1, industrial chemicals and pesticides in adults." He gave blood and urine for the study at age 48.

Davis moved to California with his family when he was four months old, and grew up in Berkeley, California. His chemical body burden is the product of his childhood and current exposures in the U.S., as well as chemical exposures accumulated during seven years of work and travel across Asia and Africa.

Among his diverse experiences, Davis has evaluated farmer training programs to reduce pesticide use in Indonesia, supervised refugee resettlement in Thailand's refugee camps, observed elections in Sri Lanka, edited news in Korea, and assisted community organizing efforts with farmer groups in the Philippines. He holds a Masters degree in International Community Economic Development.

He currently acts as a Senior Research Associate for Commonweal in Bolinas, California, where he works to eliminate the use of toxic chemicals in the healthcare industry.

Davis has hiked 1,000 miles of the Appalachian Trail in the eastern U.S., and 1,600 miles from Mexico to Oregon on the Pacific Crest Trail. He has traveled in 48 U.S. states, working as a cab driver, ship's cook, stagehand, house painter, forklift operator, janitor, construction worker, cannery fish gutter, furniture mover, and truck driver.

Lead

Neurotoxic heavy metal linked to IQ deficits and behavioral problems. Found in dust from chipping lead paint in older homes, and in some tap water.
