Birth Control Pills Threaten Fish Stocks

BarbaraHudson writes Experimental research has shown that small amounts of estrogen in waste water can lead to rapid large-scale changes in fish populations. From the article: "The lead researcher of a new study is calling for improvements to some of Canada's waste water treatment facilities after finding that introducing the birth control pill in waterways created a chain reaction in a lake ecosystem that nearly wiped out a freshwater fish. 'Right away, the male fish started to respond to the estrogen exposure by producing egg yolk proteins and shortly after that they started to develop eggs,' she said in an interview from Saint John, N.B. 'They were being feminized.' Kidd said shortly after introducing the estrogen, the number of fathead minnow crashed, reducing numbers to just one per cent of the population. 'It was really unexpected that they would react so quickly and so dramatically,' she said. 'The crash in the population was very evident and very dramatic and very rapid and related directly to the estrogen addition.'" Estrogen pollution in waterways has been an issue for over a decade now.

Can't be good for humans either

This might explain why grown men are more and more behaving like frightened old women these days.

Cities

[bill_mcgonigle]

One of the problems with cities is that they concentrate pollution. One of the dirty secrets of cities is that their governments do the bare minimum required to get rid of their waste. I remember growing up on the Jersey Shore and some days the beaches would be littered with tampon tubes because NYC just dumped their sewage offshore. When you're five, you just don't understand what's happening - I'm surprised our parents let us spend the day in that water.

The trouble is, these governments do everything they can to externalize the costs of living in the city onto the people (and apparently minnows) who don't. The wastewater treatment plants discussed here could absolutely destroy the estrogen before releasing it into the environment - but the sewage bills might have to double to make that happen. The city folks would undoubtedly scream about "unfairness" if their water was effectively treated before discharge.

Modern wastewater treatment is certainly one of western civilization's major achievements. It cuts down on communicable diseases, enhances human and animal lifetimes and makes the place smell better. However, the technology is perhaps 100 years old at it's core and was never imagined to get rid of the multitude of chemicals that we are currently dumping in the water.

As an AC in a post below this one states "We know that a whole host of chemicals do this, estrogen from birth control pills being just one chemical out of literally hundreds." Some are likely to have noticeable biological effects, others perhaps not. And we certainly have the technology to rid the water of these chemicals, but likely not the political and financial will.

The EPA is constantly changing their requirements for wastewater, typically tightening up on some chemical or another. They are usually hounded left and right when they do that for reasons of economics and politics. Hopefully they can continue doing so, but I'm doubtful of their ability to push for major changes in the current climate (pun intended).

Birth control pills signifcant contributor?

[butchersong]

This is a problem but it seems like we might have multiple contributors of estrogens in drinking water with birth control pills not the most significant. Not the best source but: http://www.sciencedaily.com/re...

That's just bullshit, not estrogen from the "Pill"

@butchersong
And why is this not "the best source" - peer reviewed... did I miss some bad science?

I thought an experiment based on a false belief that estrogen from the Pill is the same estrogen that is found in waterways was bad science - like the flawed UK research it was "based on".

The researcher refers to "estrogen-like" in the science press, but the term "birth control pills" is quoted in the non-science press. Need for publicity, bad reporting, or both?

cough*Dairy farmers*cough(??)

Should we start dumping Viagra?

[martiniturbide]

Maybe Viagra on the seas is the solution. More horny fishes will reproduce more.... damn.... I just found my master's thesis.

I don't think they're calling for ban of the pill
