The Mail online reports: Don’t go swimming while wearing sunscreen – unless you want cancer.

A compound used in the protective lotions turns toxic when it reacts with chlorine and ultraviolet rays, researchers found.

Avobenzone is considered the most popular sun-blocker in the world due to its ability to absorb sunlight at different wave lengths – preventing skin damage.

But Russian scientists suggest the UV-filtering compound forms cancer-causing toxins when exposed to a mixture of sun and chlorinated water.

Aldehydes, phenols and chlorinated acetyl benzenes were created in experiments simulating swimmers wearing sunscreen.

The latter two are considered extremely toxic and are strongly linked to deadly tumours and infertility, Lomonosov Moscow State University experts say.

While a study earlier this year hinted that aldehydes can raise the risk of cancer as they interfere with the body’s natural repair mechanism.

SUNSCREEN COULD MAKE MEN INFERTILE

Sunscreen can render a man infertile by disrupting human sperm cells, a Danish study found last April.

Nearly half of the ingredients commonly used to block out ultra-violet light mimic the effects of the female hormone progesterone.

This stops sperm cells functioning normally, researchers said at the time.

The sunscreen lotion can enter the blood stream by being absorbed through the skin.

Niels Skakkebaek, a professor at the University of Copenhagen said the findings were worrying.

‘These results are of concern and might explain in part why unexplained infertility is so prevalent,’ he said.
