Contamination of zooplankton
Well this has me concerned a sure sign of future Bioacumulation .of course this is no health concern to humans, we don't eat plankton .what does concern me is plankton are at the core of the oceans food pyrmid...tdm
Note :surrounding water was 1,000 times as radioactive and zooplankton we're 40 times the level of water .meaning the zooplankton measured is 40,000 times as radioactive as compared to before Fukushima...

Levels of the long-lived nuclear waste cesium-137 were 1,000 times higher in seawater samples taken three months after the accident than they were before the meltdowns at Fukushima Daiichi, said Nicholas Fisher, a marine science professor at New York's Stony Brook University. Zooplankton, which get carried by currents, collected in those waters had levels of cesium-137 and the shorter-lived cesium-134 that were on average 40 times higher than the surrounding water, he said. They also had much higher levels of a radioactive form of silver produced by nuclear reactions.
But the readings amounted to a fraction of the amount of radioactivity sea life is exposed to from naturally occurring potassium in seawater, Fisher said.
"The total radiation in the marine organisms that we collected from Fukushima is still less than the natural radiation background that the animals already had, and quite a bit less," he said. "It's about 20%."

"What Eats Zooplankton?
Understanding what eats zooplankton reveals the organism's crucial place in the food chain of the ocean and life in general. Without them, the fundamental building blocks of the underwater food chain would not exist. Zooplankton are the animal form of plankton, and the only creature lower than them on the food chain in the waters is phytoplankton, the plant version of plankton.
Lots of sea creatures enjoy eating zooplankton; in fact, any creature that is bigger than the zooplankton will eat them. However, there are specific species of sea beings that tend towards the zooplankton ranging from tiny sea crustaceans to giant majestic whales."
