@Nazani "Last year, the US National Association of Marine Laboratories in Herndon, Virginia, also voiced its opposition to the planned release, saying that there was 'a lack of adequate and accurate scientific data supporting #Japan’s assertion of safety'. The Philippine government has also called for Japan to reconsider releasing the water into the #Pacific.

"'Have the people promoting this going forward — #ALPS treatment of the water and then release into the ocean — demonstrated to our satisfaction that it will be safe for ocean health and human health?' asks Robert Richmond, marine biologist at the University of Hawaii at Manoa. “The answer is ‘no’.

"Shigeyoshi Otosaka, an oceanographer and marine chemist at the Atmospheric and Ocean Research Institute of the University of Tokyo says that the organically bound form of tritium could accumulate in fish and marine organisms. He says international research is investigating the potential for such #bioaccumulation of the #radionuclides in marine life, and what has already happened in the waters around #Fukushima after the accidental release of contaminated water during the tsunami. 'I think it is important to evaluate the long-term environmental impact of these radionuclides,' Otosaka says."

“A mina contamina” is a show tells the story of a drop of rain water that becomes #polluted by #heavyMetals as it falls in and underground mine. The story is told dialogically, in a conversation between the drop and a White wagtail that is warned of the perils of drinking water from the #stream, learning about the processes of #acid #mine drainage and #bioaccumulation, but also of the human #greed and #unsustainability behind mining pollution.

Alternatives To Dumping #Fukushima Wastewater Into The #Pacific

#Japan plans to dump treated, #radioactively contaminated water from the Fukushima nuclear plant into the Pacific. but it could be used in other ways instead.

"Claims of total safety are not supported by the available information. The world’s #oceans are shared among all, providing over 50 percent of the oxygen we breathe, and a diversity of resources of economic, #ecological and #cultural value for present and future generations.

"Within the #PacificIslands in particular, the ocean is viewed as connecting, rather than separating, widely distributed populations.

"Releasing #radioactive contaminated water into the Pacific is an irreversible action with transboundary and #transgenerational implications. As such, it should not be unilaterally undertaken by any country.

"The #PacificIslandsForum has had the foresight to ask the relevant questions on how this activity could affect the lives and livelihoods of their peoples now and into the future. It has drawn on a panel of five independent experts to provide it with the critical information it needs to perform its due diligence.

"No one is questioning the integrity of Japanese or International Atomic Energy Agency scientists [I am], but the belief that our oceans’ capacity to receive limitless quantities of #pollutants without detrimental effects is demonstrably false.

"For example, tuna and other large ocean fish contain enough mercury from land-based sources to require people, especially pregnant women and young children, to limit their consumption. #Tuna have also been found to transport #radionuclides from Fukushima across the Pacific to California.

"Phytoplankton, microscopic organisms that float free in the ocean, can capture and accumulate a variety of radioactive elements found in the Fukushima cooling water, including #tritium and carbon-14.

"#Phytoplankton is the base for all marine food webs. When they are eaten, the contaminants would not be broken down, but stay in the cells of organisms, accumulating in a variety of invertebrates, fish, marine mammals and humans. Marine sediments can also be a repository for radionuclides, and provide a means of transfer to bottom-feeding organisms."

There is.

As #heavymetal moves upward the food chain and guess who sits atop said #foodchain

(thats why my ol bio #teacher always proclaimed:
"humans are -strictly speaking- toxic waste... not to be buried under any circumstances )

With a half-life of 29 years, "Everyone is exposed to small amounts of Sr-90, since it is widely dispersed in the environment and the food chain. #Strontium-90 was widely dispersed in the 1950s and 1960s in from the atmospheric testing of nuclear weapons.

"Strontium-90 is also found in waste from #nuclear reactors. The accident at the #Chernobyl nuclear power plant introduced a large amount of Sr-90 into the environment. Strontium-90 was also released during the 2011 Japanese nuclear incident at the #Fukushima Daiichi Nuclear Power Plant.

"Strontium-90 can be inhaled, but ingestion in food and water is the greatest health concern. Once in the body, Sr-90 acts like calcium and is readily incorporated into bones and teeth, where it can cause #cancers of the bone, bone marrow, and soft tissues around the bone. Because Sr-90 acts like calcium, milk monitoring will be important after a large release."

@lampsofgold @somcak Even small amounts work their way up the food chain.

Paper: #Bioaccumulation of tritiated water in phytoplankton and trophic transfer of organically bound tritium to the blue mussel, Mytilus edulis

Highlights

► Tritium was bioaccumulated into organic tritium in phytoplankton cells.
► Green #algae incorporated more #tritium than the cyanobacteria.
► Organic tritium was transferred from phytoplankton to blue mussels when ingested.
► Linear uptake of tritium into mussels indicates a potential for biomagnification.
► Current legislation may underestimate accumulation of tritium in the #environment."

@Davi_Dblees Tritium "it gives off radiation in the form of a beta particle. Tritium will bind anywhere hydrogen does, including in water, and in plant, animal and human tissue. It cannot be removed from the environment once it is released. Tritium can be inhaled, ingested, or absorbed through skin." It is a big deal. #Holtec claims it's fine because it will be "dispersed" -- but #bioaccumulation, moving up the food chain, is a real consequence of dumping radioactive water!

To the #bioaccumulation crew! Starting with some DMA analysis in #cetaceans and having trouble spleen tissue that triggers an error in our DMA80evo. What could be triggering that? Any clues?
