    From the bit I watched on TV I could see a few massive holes in the research. They used a plastic bin with the bottom cut out to sample the river bed. They used a plastic cup to spoon out the water and poured it through a plastic funnel into a plastic tube. First rule in science, do not use the thing you are testing for to take the samples with. So I have no faith in there research. I have no doubt there is plastic in the river but not so sure they earned their grant money with what the BBC showed. I really do not think plastic in the rivers is what we salmon anglers need to worry about. Its all the other stuff. Everytime it rains I wonder why all the dairy farmers spread the slurry on the grass fields. I guess it is just chance not that they are just deliberately dumping it in the rivers via a field so they do not get caught.

    Some of these findings with regard to plastic particles in just about everything, whilst a tad worrying, might also be the result of flawed science. A report last week showed a number of these particles in bottled water, and they needed scientists to discover that? Any manufacturing process, has a degree of residues left over, some of which will remain within the product, plastic bottles are no different, food containers etc, etc, etc. The only way to put a stop to it, would be to stop using any plastics, and that will not happen any time soon! At least some are trying, a Dutch supermarket chain are trialling non-plastic packaging, a starting point at least.

    Yes they agreed some had probably come off the lid when they opened the bottles. But this is the media trying to cause panic not the people doing the science. Do not trust what you read in the papers. Especially when its about cleaner fish sorting out the sea problem in fish farms!

    On the one show BBC 1 tonight, they using recycled plastic , to make pellets for tarmac-ing roads,of which they hope will last longer ?up to 25yrs ? roads have been tarmac' ,and not create potholes ? and are awaiting results ? Or and quoted the plastic pellets in the tar won't break down into particles ? who are they trying to kid ? with 30 ton lorries, snow ploughs , cars with chains and studs on the wheels etc ?

    What next ? anyone remember the Kinks back in the early 70's song/record ? called "Plastic Man"

    We all are parts in the chain. There is no other way to avoid more plastic in our rivers and environment than to bring all plastic stuff back in amount and choosing daily, what material to use.
    But in presence: look at our packaged gear, lines, etc. I tested the new Hardy Rocket line. Crazy much of plastic around one line and some tips. We source the pack material out and it will be burned for producing electricity here. But elsewhere and all plastic around goods in the supermarket... Not to talk about the resources for production.
    Itís a reason why I avoid plastic bottles, donít use Fluorocarbon (duplicated lifetime to be absorbed in the environment).
    We canít heal the world, but are part of it and part of the problem. Small impact, to begin in own life, but necessary and if there are more ...

    The Environment Agency have today announced a five point plastic and PVC plan. It will include mandatory catch and release of all Coca Cola bottles that you find in your local river. Any bottle openers that you use must of course be barbless. Under no circumstances must you pack your butties in polythene ziplock bags. The would prefer that you use a good old Warburtons loaf wrapper. If you are really posh and fish some of the more snooty beats on the Eden then have your butler wrap them for you.

    Some fair points there. Certainly not an ideal experiment with possibility of contamination and observer effect.

    However, you'd think that the method and equipment they used would be standardised and therefore should give similar results before and after the flood, rather than the massive difference they actually did get.

    IMHO Plastic everywhere is something we should all be worried about. Increasing plastic pollution in rivers and on to oceans is a major issue which will be especially evident when microparticles get close to plankton and primary food density...

    Plastics in landfills and processed in incinerators ends up leaching poisons into groundwater and surface water (rivers).

    Even without that, animals eating plastic particles themselves and synthetic chemicals (and the adsorbed poisons both can bind with) have been shown to have reduced fitness, reduced breeding success and reduced longevity etc. and so we should be truly worried about them getting into the watercourses. I recall that when the point was made that certain rivers got more than their share of microplastic pollution as tyre dust from roads some didn't like the implications but... the science is formative and not many actually do like the precautionary principle in practice (unless it's stopping folk having their fun IME)

    The science is too far behind. The exponential use of plastics and the throwaway society we live in is likely to be one of the most significant issues the globe faces, IMHO.


    Anyone lobbying for a ban?

    PS - about slurry, well don't lots of farmers (etc.) spread the solid waste from sewage farms close to the rivers as well. And that of course is full of damaging microfibres from synthetic clothing etc. being washed.

    If it ain't metal, wood, paper, rock, wool, glass or natural, it's a biohazard...

    Not from a source I'd usually read, but found this online, and it poses even more questions:
