Iipolisi zesikhonkwane zingabangela ubunzima obukhulu: uphando olutsha

I-brand yakho eyintandokazi ye-nail polish ingaba nesithako esifihliweyo esinokulimaza umzimba wakho. Abaphandi abavela kwiYunivesithi yaseDuke (iU.SA) baye bafumanisa isithako esisodwa esifundweni sesilumko, esinokuyingozi, ingakumbi kubantu abavame ukumboza izipikili zabo.

Ukuphosa isikhonkwane kunye nobunzima obukhulu - ngaba kukho uxhulumaniso?

I-Triphenyl phosphate yenza i-nail ipolise ngakumbi iguquguquke kwaye ihlale ihleli. Kodwa isetyenziselwa ukuveliswa kweplastiki kunye nokukhuselwa kwefenitshala kwi-ignition. Kungenzeka ukuba i-triphenyl phosphate yongezwa kwisilumko sokugcoba ukwenzela ukuba ithathe indawo ye-phthalate, abaphandi ababhekisela kwiingxaki zokuzala. Kodwa, ngokusobala, ukutshintshwa okunjalo akuzange kuvelise ukuphucuka okufunwayo.

Izifundo zodwa zibonise ukuba i-triphenyl phosphate iphazamisa inkqubo ye-endocrine. Iimvavanyo kwizilwanyana ziye zabonisa ukuba oku kubangele iingxaki ngomsebenzi wokuzala kunye nophuhliso. Emzimbeni womntu, ukuphazamiseka kwenkqubo ye-endocrine kunokukhokelela ekuzuzeni ubunzima. Kodwa ngoku oku kuyingcamango kuphela, kwaye ukwenza izigqibo ezigqibeleleyo, izazinzulu zifuna ukuqhuba uphando olongezelelweyo.

I-Triphenyl phosphate inxalenye ye-49% yazo zonke i-varnishes, ezivivinywe lulwazi. Baye bakwazi ukufumanisa ukuba ezinye iivarnishes ziqulethe, nangona zingabonakali kwipakethe. Kwi-varnishes engenambala, inani lalo liphezulu kakhulu kunombala we-varnishes. Ezinye izifundo zibonise ukuba emzimbeni wabasetyhini le nto iqokelela ngobuninzi kunabantu. Abaphengululi bathi le nto inokuthi i-triphenylphosphate ingangena emzimbeni wesibhakabhaka ngemveliso yobuhle.

Uvavanyo olutsha lwesayensi

Abaphandi bapapasha iziphumo zomsebenzi wabo kwincwadi ethi "Environment". Bavavanya umchamo wezigulane ezingama-26 ngaphambi nangemva kokufaka i-polisi ye-nail eyayine-1% ye-triphenyl phosphate. Emva kweeyure ezingama-2-6 emva kombala wempi, inqanaba le-diphenylphosphate linyuka kancinci kuma-24 abathathi-nxaxheba-le yikhemikhali ebonisa iziphumo zokuchithwa kwe-triphenyl phosphate emzimbeni. Emva kwama-10-14 iiyure, izinga le-diphenylphosphate kubo bonke abathathi-nxaxheba kuvavanyo landa ngokuphindwe esixhenxe. Kwabathathi-nxaxheba abasebenzisa iiglavu ukusebenzisa i-nail varnish kwizikhonkwane ezingamanga, akukho tshintsho kwinqanaba le-diphenyl phosphate emzimbeni.

Iqela eliSebenzayo kwiNgqongileyo liye laphuhlisa isikhalazo kwiinkampani ezivelisa i-nail polish ukususa i-triphenyl phosphate kwi-composition yayo. Kwakhona kwiwebhusayithi yabo yashicilelwa uluhlu lweempawu ezisebenzisa le nto. Iingcali zenzululwazi zicebisa ukuba ziphephe ukubetha i-varnish kwesikhumba ejikeleze izipikili, ukuba usenokugqiba ukusebenzisa i-lacquer.
