    Default Article about sunscreen & fish.

    "However, there have been other concerns about potential health
    effects. Some clear sunscreens use nanoparticles so small that they can
    penetrate the skin and even get into the brain."

    If your suntan oil can change the sex of fish, what can do it to you?
    The stuff is not only on our skin: it's in our tap water and lunches
    too

    Spare a thought for the male hornyhead turbot. For despite its name, it
    is changing gender. And the sunscreens that symbolise bronzed sex
    appeal may be partly to blame.


    Scientists have found that male hornyhead turbot and English sole,
    feeding near sewage outfalls on the Californian coast, are being
    feminised - and a chemical found in sunscreens is the likely culprit.


    Meanwhile, Swiss researchers have found other suspected gender-bender
    chemicals from sun creams and oils building up in fish in their rivers.


    Scientists at the University of California, Riverside, found that
    two-thirds of the male turbot and sole near a sewage outfall three
    miles off the surfers' paradise of Huntington Beach, near Los Angeles,
    were growing ovary tissue in their testes. A similar study by the
    Southern California Coastal Water Research Project found fish affected
    all along the coast. The American research is the first to find sex
    changes in fish in the open ocean.


    Research on the feminising of fish in British rivers by the UK
    Environment Agency, exclusively reported in The Independent on Sunday,
    concluded in 2002 that oestrogen in urine from the contraceptive pill
    was to blame


    But the University of California scientists found that the only culprit
    they could "exclusively identify" is oxybenzone, used to protect the
    skin from the ultraviolet component of sunlight.


    Oxybenzone, which mimics oestrogen's chemical make-up, is washed off
    tanned bodies in the shower, passes through sewage works unchanged and
    settles on the seabed, where bottom-feeding fish eat it.


    The scientists suspect the sunscreens are a contributory factor along
    with other pollutants, which they have yet to identify, such as DDT and
    PCBs. The new Swiss research, however, shows two other suspected
    gender-bender substances used in sunscreen and lip balm - octocrylene
    and 4-methylbenzylidene camphor - also building up alarmingly in fish.


    They fear that people are being exposed to the chemicals several times
    over, first by putting them on their skin, and then injesting them in
    drinking water and the fish they eat. But the cosmetics industry denies
    the chemicals are dangerous, and says that"sunscreen phobia" could lead
    to more cancers. For, unlike other cosmetics, sunscreens unquestionably
    save lives. About 100,000 new cases of skin cancer are diagnosed in
    Britain each year, of which 7,300 are particularly deadly melanomas
    that kill more than 1,600 people a year. Cancer Research UK fears
    melanoma numbers will treble over the next 30 years.


    However, there have been other concerns about potential health effects.
    Some clear sunscreens use nanoparticles so small that they can
    penetrate the skin and even get into the brain.


    There is also concern about a the universal use of sunscreens. By
    shielding ourselves from sunlight, we produce less vitamin D, which
    protects against as many as 16 different cancers.

    damned if you do damned if you don't... actually i read on mua that Olay Total spf 30 contains those nanoparticles. the girl whose boyfriend is a scientist claimed he told her that, and brought up research. whoever is interested can look for it there. they have sunscreen debates go on often.

    personally i'm into European sunscreens now. dunno why mexoryl can't be approved here.

    i have really white skin and absolutely need sunscreen. just had melasma on my chest show up from being in the sun without sunscreen years ago.

    thanks Lucy for the article!

    just thought of something else: a lot of people don't even apply sunscreen as it really should be applied, as in amounts and reapplicaton every hour or few. a lot of us apply it to our faces before leaving the house and forget our hands, tops of the feet in the summer, etc. we are exposed to uv rays even when there's no sun out, even if we are outside for like 10 min a day. the point is, we get more sun when we think we are getting even if we are protecting outselves. and traditional sunscreens aren't 100%. so we are still getting the sun's benefits.

    It just means whatever makes West Hollywood & San Francisco so gay is really in the water. HA HA!

    Seriously, the waterways of California are so polluted, these transgender fish are the lucky ones. Our SW biology folks could chime in here with links to articles discussing the high amount of all kinds of pollutants in the water, especially the Bay Delta (Northern CA) and coastal waters next to Los Angeles.
