about this participant:
Vivian Chang, a community activist from Oakland, CA, participated in the -0001 biomonitoring investigation entitled "Adult Minority Leader Report." She gave blood and urine for the study on August 20, 2008 at age 38.
Vivian Chang is a community organizing expert and, until recently, the executive director of the Asian Pacific Environmental Network (APEN), based in Oakland, California.
Ms. Chang, who holds a Masters degree in urban planning from the University of California Los Angeles (UCLA), with a concentration in regional economic and community development, has worked on environmental justice issues for more than a decade.
She has been particularly instrumental in organizing Asian immigrant communities around environmental conditions in Richmond, California, site of a Chevron oil refinery.
As she told ColorLines Magazine last spring, "In many ways, low-income Asian immigrant and refugee communities face the very same economic and environmental issues that other low-income communities of color face. They live in the same dilapidated, overcrowded housing by the freeways that Latinos and African American communities live in. They work in industries rife with hazards and poisons-be it formaldehyde fumes in textiles, or arsenic dust in high-tech chips or caustic cleaning agents in the janitorial jobs."
