Onto a bigger scale... The entire west coast is HEAVILY contaminated with mercury due to the gold mining and the amount of mercury they used.
Across the state, subsistence fishers — low-income anglers often from immigrant communities — fish to feed their families. Yet a state study determined that fish in 99% of coastal waters and 49% of freshwaters exceed safe levels established for eating.
Mercury and polychlorinated-biphenyl (PCB) contamination is particularly alarming in the San Francisco Bay and the Sacramento-San Joaquin Delta. In 2001, a Contra Costa County study determined that 70% of local anglers surveyed were Asian, African American or Latino, and 73% regularly ate fish that can be unsafe to consume.
