Two events in the early 1990s a die-off of seals in the Barents Sea and White Sea from blood cancer, and the deaths of millions of starfish, shellfish, seals and porpoises in the White Sea have been variously attributed by Russian scientists to pollution or nuclear contamination.How the radioactive materials released from the Fukushima plants will behave in the ocean will depend on their chemical properties and reactivity, explained Ted Poston, a ecotoxicologist with the Pacific Northwest National Laboratory, a U.S. government facility in Richland, Washington. Its only within the primary circuit, which is surrounded by multiple layers of containment. Depending on where the blast occurs (air or ground), the scale and effects of the fallout may differ. However, lingering radiation from fallout may last for decades. Even the mass dumping of nuclear material by the Soviets in the Arctic has not been definitively shown to have caused widespread harm to marine life. A review committee concluded that boron impurities might be poisoning it by absorbing neutrons. Ionization can cause damage within a cell, which could eventually lead to cancer, a mutation in genetic material, or more immediate types of physical harm to humans. But scientists agree that the governments of Japan, the United States, and other nations on the Pacific Rim need to ramp up studies of how far this contamination might spread and in what concentrations.Given that the Fukushima nuclear power plant is on the ocean, and with leaks and runoff directly to the ocean, the impacts on the ocean will exceed those of Chernobyl, which was hundreds of miles from any sea, said Ken Buesseler, senior scientist in marine chemistry at the Woods Hole Oceanographic Institution in Massachusetts. Many objects can be penetrated, but are slowed by water. All matter is composed of atoms. The U.S. Environmental Protection Agency (EPA) is monitoring airborne radiation, but its spokespeople were unable to say whether the EPA was monitoring the marine environment as well.Experts such as Buesseler of Woods Hole, as well as activists like Bernek, said an international effort should quickly be launched to sample and measure radionuclides in the ocean, seafloor, and marine life, with close attention paid to which direction ocean currents can be expected to transport water potentially contaminated by Fukushima.
