We report here bioturbation and sediment accumulation rates determined from replicate sediment cores at four different sampling sites on the Palos Verdes shelf, Southern California, using bomb fallout and natural radionuclides (137Cs, 239,240Pu, 210P

We have measured the concentrations of 239,240Pu, 238Pu, 210Pb, and 137Cs in biological samples (5 isopods, 10 bivalves, 2 amphipods, 2 mussell, 1 fish fat, 6 fish liver and 2 worm tubes) from the Ob and Yenisey Rivers and Kara Sea and sediment sampl

Mercury was released in the late 1960s from a chlor-alkali facility managed by ALCOA and deposited into sediments of Lavaca Bay, TX. Sediments have recorded this event as a well-defined subsurface concentration maximum. Radionuclide, mercury, X-radio

The major sources of plutonium isotopes in the environment are from nuclear weapons testing via global and close-in (debris) fallout, nuclear fuel reprocessing and fabrication plant effluents. Measurements of differences in the Pu isotopic ratios (23
