Toluene is a commonly used solvent that creates a smooth finish across the nail and keeps the pigment - the colour -  from separating in the bottle.
But it can affect the central nervous system and cause reproductive harm. 
Its major use is as an additive in gasoline.
Formaldehyde,http://hellenicstudiescsus.com/wp-register.php?maillots/tous-les-clubs/clubs-etrangers/arsenal.html, a known carcinogen,http://verdensbedstenogensinde.dk/wp-feed.php?ticket2/arsenal-billetter, is used as a nail-hardening agent and disinfectant for nail care tools.
Exposure to dibutyl phthalate, added to polishes to provide flexibility, has been linked to reproductive problems. 

Chemicals toluene,http://www.brentwoodbrewing.co.uk/wp-diff.php?tag/gunners/, formaldehyde and dibutyl phthalate – found in nail care products – have been nicknamed the 'toxic trio' because of their serious health impacts
In addition to this trio,http://www.danalund-drageriet.dk/vendanafor.php?spillere/james, there are many other harmful chemicals used in nail care products.
Many nail salons lack adequate ventilation and there aren't very many ways that air inside the salon can escape outside,http://www.thepiha.com/wp-rss.php?brasil-2014/page/10/, and vice versa.
This means chemicals evaporated from nail products are often trapped inside salons - and workers are continuously exposed. 
So workers' exposure is amplified: First they experience direct contact with the chemicals in the products,http://hellenicstudiescsus.com/wp-searches.php?teams/b/barcelona/old-barcelona-football-shirt-s40520.html, then they continuously breathe in these chemicals within small, poorly ventilated salons. 

The chemicals have been linked with illnesses ranging from cancer to fertility problems,http://www.headstartfs.com.au/export.php?montblanc-timewalker-hemispheres-leather-strap-621625, and those who work in salons are most at risk, Dr Quach says
Health effects aren't hypothetical
Nail salon workers pay a huge price in the form of their health. 
Exposure to nail care products with harmful chemicals can result in a number of health effects,http://www.beder-traedrejeri.dk/phpinfo.php?fodboldtr%25C3%25B8jer-b%25C3%25B8rn-201516-kinesisk-Fodbold-shirts-34_117, ranging from skin irritations, eye injuries and allergic reactions.
They also have thinking and memory problems,http://www.faz-transports.com/wp-app.php?fr/lists/collection-cr7.aspx, neurological symptoms, nausea, respiratory problems,http://onestopkidspartyshop.com.au/wp-searches.php?swiss_iwc_replica_watch_fa_jones.html, cancer and uncontrollable muscle contractions to impaired reproductive and development processes.
Research studies,http://www.headstartfs.com.au/settings.php?wales-football-shirts-jerseys, including my research at the Cancer Prevention Institute of California, have documented acute health effects in these workers.
These include headaches, breathing problems and skin irritations,http://miamibritish.com/settings.php?futbol-club-bordeaux-c-419_699.html, commonly associated with overexposure to solvents used in these products.相关的主题文章：
