Drug Pollution In Rivers Reaching Damaging Levels For Animals and Ecosystems, Scientists Warn (independent.co.uk) 102

pgmrdlm shares a report from The Independent: Medicines including antibiotics and epilepsy drugs are increasingly being found in the world's rivers at concentrations that can damage ecosystems, a study has shown. Dutch researchers developed a model for estimating concentrations of drugs in the world's fresh water systems to predict where they could cause the most harm to the food web. The study, published in Environmental Research Letters, focuses on two particular drugs: antibiotic ciprofloxacin and anti-epileptic drug carbamazepine. Between 1995 and 2015 it found that rising concentrations of the drugs and the increasing number of water tables affected meant the risks to aquatic ecosystems are 10 to 20 times higher than two decades earlier.

Carbamazepine has been linked to disrupting the development of fish eggs and shellfish digestive processes, and the study found potential risks were most pronounced in arid areas with a few major streams. The risks were much more widespread for ciprofloxacin, with 223 of 449 ecosystems tested showing a significant risk increase. More worrying still, when [the researchers] compared their predictions to samples from four river systems they found their model was underestimating the risk. Pharmaceutical residues can enter these fresh water systems through waste water from poorly maintained sewer systems, or from run-off over fields for drugs used in livestock.

      Spent 2 years back in the 90s working on trials with poly-chlorinated bi-phenyls (PCBs, also the active ingredient of agent orange), where we raised tadpoles in water solutions with varying levels of PCBs. We had Xenopus Laevis (kind of the white mouse of frogs) and a host of eastern US rana species (green, bull, pickerel, leopard). Don't recall the dosages anymore. At the higher ones, the tadpoles wouldn't live to adulthood due to under-development of their GI tract and liver. At the lower dosages, how

      I got to ask... did the researchers find any actual damage done? Because that's what's important and I do not see that relayed in the article. When I read the article I saw of words/clauses like [paraphrasing]... 'may/could/can do harm'...'potential effect'...'elevated risk'... 'our model predicts'... 'link to effect'... etc. None of which mean environmental damage is occurring. The closest this article comes to stating actual environmental damage is this:

    Do not be surprise we see antibiotic resistance. First we gave antibiotic to cattle just in case, and then we pour some into rivers. Many microbes will get exposed to it, and some will adapt.
    • by Anonymous Coward

      That's a very real but smallish effect of the overall damage we're doing dumping pharmaceuticals into the environment. It's incalculable. Waste water treatment even in the best case will never be able to stem the flow.
      People just dump their old pills right down the toilet without thinking, by the millions.

    A while back we went to go look at a work-for-rent cabin outside of Willits, on a supposedly permacultural demonstration farm. Turned out the owner had workshops there, and she had attendees shit in buckets in an outhouse, then literally buried the shit in a hole next to the river that some neighbor dug for her with his backhoe. This person recently gave the keynote speech at a local farm conference. So as it turns out, both municipal waste management systems and hippies in the woods are shitting up our water systems. You might say it's end-to-end.

      Your weird coprophile anecdote has nothing at all to do with the topic.

      • C'mon, the username fits the story very nicely.

      • It was actually coprophobia, because the primary reasons we weren't interested were the poor waste management, and that we would be responsible for dumping the shit buckets in the hole down by the river.

    • Would it possibly be better to bury these medications (away from a river)? How about mixing them up with something first to decompose/denature them, or disposing of them in used cooking oil, used paint, or other household products that are discarded in bulk containers? It just seems that anything that makes it more difficult to get rid of these medications is prone to making them victim to absent-minded cleanup down the drain.

      • I assume most of the medications in the sewage water are there because they are not completely metabolized, and we pee/poop them out.

    • Username checks out.

  • Odd medication to complain about. Crbamazepine (Tegretol) was a highly used seizure/epilepsy medication 25 years ago, and to lesser extent, used for migraines or bipolar disorder. Now it is rarely used for any of these.

    I'm puzzled why there is particular concern over a medicine that is rarely used any more.

      I was surprised as well. Why not concentrate on estrogen as from my understanding it's causing the biggest issues in aquatic life. I guess that's too politically sensitive. Can't suggest the pill is causing environmental damage even though it's fairly well documented.

    While other drugs may be an issue, the elephant in the room is agriculture. For vegetable, big ag uses all sort of pesticides and fertilizers that wind up polluting the water. For animals, they use antibiotics.

    The antibiotics are not even meant to preserve animal health, although that's a nice side effect. Weirdly, animals on antibiotics gain weight more quickly, which is (afaik) the real motivation. But these antibiotics wind up in the waste, and from there in the runoff and in the rivers.

    What we need is simple: an absolute prohibition on medicating animals that are not sick. Period.

    p.s. It's a bit off-topic here, but: the prices for the antibiotics have to be cheap, for this to work economically. The exact same antibiotics for people are generally massively higher. An interesting comment on big pharma.

      Considering that Antibiotic use for anything other than illness has been illegal for a long time, and it costs money, I think you're woefully misinformed in current day agricultural practice. Pesticides and fertilisers are sparingly used (and agriculture does a lot of research on the minimum spray doses they can use; after all, that costs money too).
      So your 'we need is a prohibition on medicating animals that aren't sick' already exists.

        That's a nice thought but it isn't the case in practice. There are many feedlots that feed all their animals CTC Crumbles for instance and I can tell you that inject able antibiotics are routinely used as a preventative and not to treat anything... you just need a vet signoff but when your business is feedlot beef, that is just paperwork. This is in the states. God knows what it is like in China.
