    Iron dissolved by air pollution may increase ocean potential to trap carbon

    From: University of Birmingham
    Published March 3, 2017 10:52 AM

    Iron particles generated by cities and industry are being dissolved by man-made air pollution and washed into the sea – potentially increasing the amount of greenhouse gases that the world’s oceans can absorb, a new study suggests.

    Scientists have long believed that acids formed from human-generated pollution and natural emissions dissolve iron in airborne particles – increasing the amount of iron to the ocean – but have lacked direct evidence to prove this theory.

    Now, iron-rich particles from steel manufacturing and coal burning, collected in the East China Sea, have been found to have a thick sulphate coating containing soluble iron that provides the ‘smoking gun’ to prove the theory of acid iron dissolution.

    Scientists at the University of Birmingham (UK) and Shandong University (China) led an international research partnership with counterparts from universities in US and Japan. The work was funded by the Natural Science Foundation of China and the UK’s Natural Environmental Research Council. The team published their findings in Science Advances.

    2. And how does too much iron in the oceans

    Affect the ocean’s flora and fauna? Also iron feeds cancer, making cancer cells more likely to adhere to a mammal’s tissues and organs rather than being flushed away..

      3. Now years ago, in the 90's I think, there were ocean experiments on iron

      enrichment, and there was some evidence of resulting blooms in algae, though as I remember it was modest.

      There was a biochemist, I can’t remember his name, that said “give me a tanker of iron and I’ve give you an ice age”.

        4. I remember him saying that,

        But at the time he did not seem concerned about examining what iron would do. He had his mantra about it being a solution for Global Climate Change, but he sure didn’t think about the rest of it.

        I mean, would mama whales want to be ingesting the stuff in their last trimester?

        The government always acts as though those in charge of operations will be responsible about whatever stuff they dump through aerolization, but usually the moment some plan gets approved, the most irresponsible methods of dispersal are used.

          5. I don't remember it all clearly, but I think that a UN Fisheries Commission

          voiced concerns and the ‘field’ experiments were opposed.

      6. and what does the increased carbon load do to the oceans?
