Ratio of Plastic #politicians purloined by #Plutocracy ?

#Plankton consume #microplastics directly.
Fish eat plankton.
Bigger fish eat smaller fish.
Humans eat the big fish — and with them, every plastic fragment they've accumulated.
S0-CALLED trophic magnification or #biomagnification or bio accumulation

> 生物が外界から取り込んだ物質を外界よりも高い濃度に体内に蓄積する現象も「生物濃縮(#bioconcentration)」といわれますが、上記の生態系を通じて食物連鎖によっておこる「 #生物濃縮#biomagnification)」とは区別されています。さらに、呼吸と食物の両方からの化学物質の取り込みによる濃縮を「生物蓄積(#bioaccumulation)」として使い分けることもあります。

食物連鎖により、農薬は濃縮されていくのではないですか。|自然や環境への影響は?|教えて!農薬Q&A|JCPA農薬工業会

JCPA農薬工業会の食物連鎖により、農薬は濃縮されていくのではないですか。についてご紹介いたします。

> The fatty storage depots act as biological magnifiers, so that an intake of as little as of 1 part per million in the diet results in storage of about 10 to 15 parts per million, an increase of one hundredfold or more. These terms of reference, so commonplace to the chemist or the pharmacologist, are unfamiliar to most of us.
#RachelCarson on #BioAccumulation and #DDT in #SilentSpring 1962 #BioMagnification
Four visualizations of BioAccumulation (or BioMagnification) found on-line. One day I hope to train with Racket's plot and try to visualize the difference in concentrations with squares, and maybe color gradients too. I can't imagine how to get the differences into one eye-span now though. It will take a day or two of experimenting.

Among #orcas stranded in the UK, levels of #PCBs, a group of highly dangerous and persistent chemicals that do not degrade easily, were 30 times the concentration at which the animals would begin to suffer health impacts, researchers said.

Scientists described the findings as a “huge wake-up call”. #Biomagnification #FoodChain #pollution

Levels of toxic PCB chemicals found at 30 times ‘safe’ limits in stranded whales

Studies of cetaceans stranded in UK waters show high levels of toxins 20 years since global ban of most PCBs, say scientists

One day it would be great to work on views (visualizations) of #BioAccumulation ( #BioMagnification ) for Minamata, and for the great desciption of Clear Lake in Rachel Carson's _Silent Spring_
