Samuel N. Luoma, Theresa S. Presser
2000, Open-File Report 2000-416
During the next few years, federal and state agencies may be required to evaluate proposals and discharge permits that could significantly change selenium (Se) inputs to the San Francisco Bay-Delta Estuary (Bay-Delta), particularly in the North Bay (i.e., Suisun Bay and San Pablo Bay). These decisions may include discharge requirements...
The materials flow of mercury in the economies of the United States and the world
John L. Sznopek, Thomas G. Goonan
2000, Circular 1197
Although natural sources of mercury exist in the environment, measured data and modeling results indicate that the amount of mercury released into the biosphere has increased since the beginning of the industrial age. Mercury is naturally distributed in the air, water, and soil in minute amounts, and can be mobile within and between these media....
