Paint Dust Covers the Upper Layer of the World's Oceans 141

sciencehabit (1205606) writes Even when the sea looks clean, its surface can be flecked with tiny fragments of paint and fiberglass. That's the finding from a study that looked for plastic pollution in the uppermost millimeter of ocean. The microscopic fragments come from the decks and hulls of boats, and they could pose a threat to zooplankton, an important part of the marine food web.

        It's important not to accept any input as pure fact on its face. It's equally important to accept facts that are verified, even if inconvenient. Far too often, "healthy skepticism" is another way to say "inconvenient so LA LA LA LA LA (fingers in ears)".

        Fact is that micro pollutants are just now entering the threshold of human understanding - and it's a bigger problem than just about anybody guessed.

            The current AGW situation is not driven by the current output of CO2.
            It is driven by the output during the previous 150 years. Sure, we are on peak output, but ten years of what we put out right mow is far away from what we did the last hundred years.
            Nevertheless the problem is right now.
            Exactly the same as with the article we talk about.

            No, no it does not. You can make that assumption, but it is not in any way supported by the given evidence. That we're finding out about it now only means that we've found out about it now; it tells us nothing about the scope. A whole new family of plastics was just invented by accident. You don't think we've been looking for new plastics? And it's not like it was some strange new combination of things, it was leaving out an ingredient. The truth is that we miss things all the time which look obvious in hin

        • Fact is that micro pollutants are just now entering the threshold of human understanding - and it's a bigger problem than just about anybody guessed.

          Fact is, that's a logically inconsistent statement. If it's just now entering the threshold of human understanding, than there can't possibly be enough evidence to call it a "bigger problem than just about anybody guessed". Unless, of course, nobody thought it was a problem at all - in which case they wouldn't be called pollutants, but unicorn dust or leprechaun farticles.

          • In your rush to correct people you failed to account for the meaning of "human understanding". It doesn't mean that just one human understands. The above sentence makes it clear that someone may well have guessed, but that the general assumption has been that there was no problem.

            Someone always gets it. Unfortunately, they are usually ignored until it's too late.

        • > Fact is that micro pollutants are just now entering the threshold of human understanding

          Or perhaps micro pollutants are just now entering the threshold of human measurement, and the News is reporting it because it's a new thing. (Hence the name.)

        We'll have to see what the effect ends up being; but there is reason to be a bit concerned about marine paint. Hull fouling is a drag and people go to some lengths to avoid it. Hull paints formulated to slow fouling are quite common and work by being enthusiastically biocidal.

        The problem with alarmism is that it makes people skeptical about everything, even real problems. After people read so many stories about the worlds glaciers melting by 2030, and the giant continent sized island of trash in the Pacific, and then later find out that these are wild hyperbole, they stop taking anything seriously. People like Al Gore, that try to scare people into action by exaggerating problems, do a great disservice. We are all better off just telling the truth.

        I do take it with skepticism. I can also do basic math.
        Unless something changes, things tend to continue moving on the same direction. If the amount of paint residue on the oceans is increasing steadily, it will continue to increase (again, if nothing changes).
        So yeah, there is cause for worry, maybe even alarm. Panic? No. Panic will be when we start seeing large scale effects of this.

    On average, a liter of water from the microlayer contained 195 particles—this concentration is 10 to 100 times higher than microplastic particles in water collected by other methods.

    One litre of water is 1,000,000 cubic millimetres. Given a depth of 1 mm that would cover 1 square meter. So therefore 195 particles per square meter. They don't go into how big these particles are. The issue is that these particle float and therefore would be concentrated in the upper 1 millimetre of water. They have not shown it is a problem.

      • The homeopaths would lead you to believe that this is roughly 10^98 times too concentrated to work. Oh, and that it would make you immune to paint.

        It depends on whether the particles are accumulating faster than they are leaving the system. If the figures we're talking about represent an equilibrium that will continue indefinitely into the future, surely we are not doomed. But if the concentration of particles is increasing and people need to do something about this before it becomes a problem, we might be.

          That's not a good thing. Paints are overwhelmingly still colored with things we don't want in the food chain. We really don't want plankton to metabolize these particles. We want them to stay as intact as possible for as long as possible, ideally until they somehow end up on the ocean floor or in a cleanup project somewhere — but anywhere that won't put them into the food chain or drinking water would be fantastic.
