Microplastics and ocean health.

Two quick n easy films, thought provoking and incorporating two of my favourite interests, diatoms and the microscope.

One salient point drawn from each film:

  • Our salt contains microplastics (remember the blood / brain barrier) that only become visible when examined with a quite simple bench microscope.
  • Every fifth breath we make is supplied by the function of diatoms.

Diatoms appear to be now severely compromised, in my simple google searches its near impossible to obtain up to date information. I’ve read several times that diatom CO2 to O conversion is equivilant to the value of the rain forests for the same task. ie 20% contribution to world CO2 to O.

 

 

Most of the microscope footage is pretty well as you would see it at home with a medium price bench microscope. A spend of say £100-200 for a secondhand ‘scope would do all you want. I use a binocular Biolam obtained from a microscopical society here in the UK thirty years ago and was available as the original user had failing eyesight and had to go into care. I seldom use anything other than low mag for algal samples, diatoms etc say x100, of the four powers available I only use the lower two. Theres no need to buy new.

Note also that diatoms produce a gas DMS that was only in the 1970’s detected by independent scientist James Lovelock as is very important for oceanic weather systems.

 

The other big question I need to find out about is present contamination from nano-particle aluminium, as in the embedded youtube of around three posts ago ‘Lines in the Sky’ professional (retired) fisheries biologist Frances Mangels tells us that nano-particle aluminium is a billionth of a metre ie one thousandth smaller than particles of tobacco smoke. If my reading of this and my arithmetic is sound, we can write this as :-

tobacco particle = 1m x 10 power minus 6 (written 10^-6) ie take off three 0’s for a metre to millimetre conversion which gives 0.001mm ie one thousandth of a millimetre.

nano-particle aluminium = 1m x 10 power minus 9 (1m x 10^-9) will be one thousandth of the above ie 0.000001mm which in my opinion is way beyond what can be detected with an ordinary light microscope.

hint : remember 10^-2 mm is one hundredth ie 0.01mm  therefore 10^-3 is one thousandth ie 0.001mm

In my opinion its always much easier to talk as dec fraction of a millimetre (mm) when dimensions are sub-millimetre. As a practical engineer this is ALWAYS how it would be handled, far less room for error.

Realise that nano-particle aluminium is a far far smaller an aluminium particle that could ever occur in nature and therefore poses threats we would never have dreamed of.

As I write this piece we have an aluminised sky above, a strange grey, yesterday Sat 28 Dec 2019 was a lot of chemtrail over Europe as found on NASA Worldview and when out this morning 0930 yet again there are chemtrails being laid at high alt. Do many register this, anyone question it ???

plastics recycling is mostly pretence.

I’d like to think I’m wrong but I doubt it, most plastic is not recyclable, its just heaps of unmanageable crap, plain and simple and often is transported to another unseen country across the planet. Its too small its too jumbled and of too great a volume to be capable of micro-processed to any satisfactory level, the economics of it do just not work for an ethical outcome.

What really bugs me is endlessly there is never any mention of the profound difference between thermoplastics and thermo-setting plastics, the same difference as a vacuum formed food tray and a resin/phenolic based fibreglass component. Some will reform and some just char and become useless. This is day one hour one of any materials course at day release technical college or thirteen year old  science / chemistry school lesson and is utterly fundamental to any consideration or  understanding of how to recycle.

Not exactly the clearest explanation … https://www.difference.wiki/thermoplastics-vs-thermosetting-plastics/

Clearer … https://www.modorplastics.com/plastics-learning-center/thermoset-vs-thermoplastics/…

Its also fundamental we navigate away from short life throw away food and provisions that arrive in such small and tricky to recycle packaging.  Its also endemic with pharmaceutical and say vetinary products, often over-designed and plastics technology gone mad. It is the smallness itself of the discarded parts being part of the problem. In my own lifetime I can remember Co-op blue paper bags for dry goods, filled as required when out shopping. In a sense our own disaster is written into the so-called present day solutions we have arrived at.

Food is over-packaged and too few people cook from scratch.

Here below is the article that prompted me to write this post … https://unearthed.greenpeace.org/2019/07/01/for-the-sake-of-the-climate-we-must-stop-believing-magical-stories-about-plastics-and-recycling/

 

Crap on the beach …

I remember meeting someone maybe thirty years ago, he knew of me as a clever man technically and wanted to get me involved in the business of his new employer ie plastic injection moulding. My only and absolute reaction was along the lines of ‘hasn’t the world got enough plastic crap without making more of it’ … to my mind the only and absolute reaction possible. He just couldn’t understand how I felt about this in 1988.

As the article above mentions, meal packaging is obscene, every time for every portion theres plastic crap to go with it in our convenience world, but how inconvenient for the birds, animals and marine life many miles away from human activity that are landed with the result.

Lots of articles worth reading from newsdeeply.com …
