    Plastic fibre a 'major pollutant'

    By Tim Hirsch
    BBC environment correspondent

    Tiny pieces of plastic and man-made fibres are causing contamination of the world's oceans and beaches, the journal Science has reported.
    Even remote and apparently pristine layers of sand and mud are now composed partly of this microscopic rubbish, broken down from discarded waste.

    This is the first assessment of plastic fragments accumulating in sediments and in the water column itself.

    It is not yet known what the long term affects of this pollution may be.

    A team led by scientists at the University of Plymouth took samples from 17 beaches and estuaries around the UK, and analysed particles which did not appear to be natural.

    The researchers found that most samples included evidence of a range of plastics or polymers including nylon, polyester and acrylic.

    They also found that when creatures such as lugworms and barnacles fed on the sediments, the plastics turned up inside their bodies within a few days.

    To test whether this contamination was getting worse, the scientists analysed plankton samples taken from survey ships between Scotland and Iceland since the 1960s - and found that the plastic content had increased significantly over time.

    Toxic chemicals

    Because the team only sampled particles which looked different from natural sediments, it's believed that the true level of plastic contamination could be much higher.

    Given the durability of plastics this type of contamination is likely to increase

    Dr Richard Thompson, University of Plymouth
    The lead author of the study, Dr Richard Thompson, said "Given the durability of plastics and the disposable nature of many plastic items, this type of contamination is likely to increase.

    "Our team is now working to identify the possible environmental consequences of this new form of contamination."

    One concern is that toxic chemicals could attach themselves to the particles which would then help to spread them up the food chain.

    That research is for the future, but this study suggests that practically everything really is made of plastic these days - even the oceans.

    I saw a documentry on this subject, talk about making you want to stop using plastics (like that can ever happen, they even admitted that in the documentry). They showed how much birds ingest, how plankton feeders scoop it up as plankton (ie. jelly fish with loads of plastic fibers in their bodies). Its every where.

    Oh yah, the plstic fibers are an attractent to pollutants. When they are consumed, so is the oil and other junk stuck to the plastic.
