游泳时不要再涂防晒霜了
Don't go swimming while wearing sunscreen - unless you want cancer.
除非你想得癌症，不然千万别涂着防晒霜去游泳！
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.
