"Severely criticised by their political opponents for neglecting their official duties, it was said that they had no thought but to live out their days in rural retirement."

Forget radiation: Micro plastics contaminating fish now showing up in humans
From the story here:
Seafood eaters ingest up to 11,000 tiny pieces of plastic every year with dozens of particles becoming embedded in tissues, scientists have warned, in findings described as 'sobering' by the Prince of Wales. Researchers from the University of Ghent in Belgium believe that microplastics accumulate in the body over time and could be a long term health risk.
What a horrible development, all thanks to everything plastic finding its way into the oceans, from particles from washing your fleece clothing to plastic micro beads in personal care products and cleansers which pass into the seas.
Read a study about it here.
Everything that lives in the water worldwide appears to be in danger, especially shellfish which filter lots of seawater, but particles were found in a majority of species from the Adriatic to the North Pacific to China to Brazil:
Data analysing fish caught in the wild and sold for human consumption at markets found the following: “In Indonesia, anthropogenic debris was found in 28% of individual fish and in 55% of all species. Similarly, in the USA, anthropogenic debris was found in 25% of individual fish and in 67% of all species. Anthropogenic debris was also found in 33% of individual shellfish sampled. All of the anthropogenic debris recovered from fish in Indonesia was plastic, whereas anthropogenic debris recovered from fish in the USA was primarily fibers”.

Radioactive Salmon?
The Vancouver Sun provides this discussion of the possible impact of the Fukushima nuclear plant disaster on Pacific Ocean salmon:
Radioactive water leaking from a reactor at Japan’s damaged nuclear plants isn’t likely to harm [British Columbia] salmon because they don’t travel as far as the coast of Japan, said Nancy Davis, deputy director of the North Pacific Anadromous Fish Commission.
“They tend to go to Gulf of Alaska, the Bering Sea, or maybe as far as the central North Pacific, but they are not maturing off Japan and swimming all the way back here,” Davis said. “Immature and maturing salmon are in the deep ocean, they’re not on the Japanese shelf or near the nuclear plant.”
She said it’s possible that Japanese chum salmon might be in the waters near the damaged plant, but that they would not be returning to Japan for another three or four years. Japan mostly produces chum salmon, which Davis said is very unlikely to be imported into British Columbia.
Davis said it is important to consider what elements are involved and what their half-lifes are, and how the salmon would come into contact with the radioactive materials.
Another [Simon Fraser University] professor said he could not say what the effects on salmon would be.
“Given the limited information available, I cannot even speculate about the effects of radiation leaking into the ocean. It is far too early to say anything with any confidence,” said Randall Peterman, SFU professor and Canada research chair in fisheries risk assessment and management.
For the rest of the article, which also discusses radioactive contamination of seaweed, go here.
We eat a fair amount of wild Alaskan salmon in our house, and will continue to do so.
