Kwa diso losaphunzitsidwa, mndandanda wazinthu zazitali kumbuyo kwa mascara phukusi kapena botolo la maziko likuwoneka ngati lalembedwa mchilankhulo china chachilendo. Popanda kutanthauzira mayina onse a masilabi asanu ndi atatuwo nokha, muyenera kuyikapo pang'ono.of trust - kuti mapangidwe anu ndi otetezeka komanso kuti mndandanda wazowonjezera zake ndiwolondola - mwa asayansi omwe amapanga njira zanu zopangira. Koma phunziro latsopano lofalitsidwa mu magazini Makalata a Sayansi Yachilengedwe ndi Zamakono zikuwonetsa kuti, mwina, simuyenera kufulumira kukhulupirira zomwe mukuyika pankhope panu ndi thupi lanu.

Pambuyo poyesa zodzoladzola 231 - kuphatikiza maziko, mascaras, obisalira, ndi milomo, diso, ndi nsidze - kuchokera m'masitolo monga Ulta Beauty, Sephora, ndi Target, ofufuza a University of Notre Dame adapeza kuti 52% inali ndi magawo ambiri polyfluoroalkyl zinthu (PFAS). Wotchedwa "mankhwala osatha," PFAS sichiwonongeka m'deralo ndipo imatha kukhala mthupi lanu ndikuwonekera mobwerezabwereza pakapita nthawi, monga kumwa madzi owonongeka, kudya nsomba zam'madziwo, kapena kumeza mwangozi nthaka kapena fumbi, kwa Centers for Disease Control and Prevention. Mankhwalawa amagwiritsidwa ntchito popangira zophikira zopanda ndodo, zovala zoteteza madzi, komanso nsalu zosagwirizana ndi banga, pa CDC.

M'dziko lokongola, PFAS nthawi zambiri imawonjezeredwa kuzodzola ndi zinthu zodzisamalira (lingalirani: mafuta odzola, oyeretsa nkhope, mafuta ometa) kuti athetse kukana kwamadzi, kusasinthasintha, komanso kulimba kwawo, malinga ndi kafukufukuyu. Pazinthu zophatikizira, PFAS nthawi zambiri imaphatikizira mawu oti "fluoro" m'maina awo, malinga ndi Environmental Working Group, koma kafukufukuyu adapeza kuti 8% yokha ya zodzoladzola zoyesedwa ndizomwe zili ndi PFAS monga zosakaniza. Pazigawo zisanu ndi zitatu zodzikongoletsera zomwe zidayesedwa, maziko, zopangira diso, mascaras, ndi milomo ndizo gawo lalikulu kwambiri lazogulitsa zomwe zimakhala ndi fluorine wambiri (chikhomo cha PFAS), malinga ndi ochita kafukufukuwo.

Sizikudziwika ngati PFAS idawonjezedwa dala pazinthu izi kapena ayi, koma ofufuzawo akuwonetsa kuti akadayipitsidwa panthawi yopanga kapena pakuchotsa zosungiramo. Bungwe la U.S. Food and Drug Administration likunenanso kuti PFAS ina ikhoza kupezeka mosadziwa mu zodzoladzola chifukwa cha zosafunika kapena "kuwonongeka kwa zinthu za PFAS zomwe zimapanga mitundu ina ya PFAS."

Mosasamala chomwe chimayambitsa, kupezeka kwa mankhwalawa kumasokoneza pang'ono: Kuwonetsa kuchuluka kwa PFAS kungayambitse kuchuluka kwa mafuta m'thupi, kuchepetsa kuyankha kwa katemera mwa ana, chiwopsezo cha kuthamanga kwa magazi mwa amayi apakati, komanso chiwopsezo cha impso. ndi khansa ya testicular, malinga ndi CDC. Maphunziro a nyama - kugwiritsa ntchito Mlingo wokwera kwambiri kuposa momwe amapezekera mwachilengedwe - awonetsanso kuti PFAS imatha kuwononga chiwindi ndi chitetezo chamthupi, zilema zobadwa nazo, kuchedwa kukula, komanso kufa kwakhanda, malinga ndi CDC.

Ngakhale ngozi zomwe zingachitike zimapangitsa kugwiritsa ntchito PFAS mu zodzoladzola kukhala chinthu chodetsa nkhawa, akatswiri amachenjeza kuti asadzitengere oipitsitsa. "Sizikudziwika kuti ndi zochuluka bwanji zomwe zimalowetsedwa [kudzera pakhungu] ndi kuchuluka kwa anthu omwe amadziwikiratu potengera kuchuluka komwe kumapezeka pazodzoladzola," akutero a Marisa Garshick, M.D., F.A.A.D., dermatologist ku New York City. "Chifukwa chake chifukwa [zotsatira]zo [zidawoneka] mu maphunziro omwe adachitika pa nyama, zomwe zidapatsidwa kuchuluka kwa [PFAS], satero zikutanthauza kuti izi zitha kugwira ntchito munjira iyi, pomwe kuchuluka kwake sikudziwika."

Komabe, ndikofunikira kudziwa kuti zodzoladzola zoyesedwa phunziroli zitha kugwiritsidwa ntchito pankhope, kuphatikiza mozungulira maso ndi pakamwa - madera "omwe khungu limakhala locheperako ndipo pakhoza kukhala kuyamwa kambiri poyerekeza ndi ziwalo zina za thupi," akutero Dr. Garshick. Momwemonso, olemba kafukufukuyu akuwonetsa kuti PFAS yomwe ili pamilomo imatha kulowetsedwa mwangozi, ndipo omwe ali ndi mascara amatha kuyamwa kudzera munjira zokhetsa misozi.

Ndiye, kodi muyenera kutaya zodzoladzola zanu zonse m'zinyalala? Ndizovuta. Lipoti la 2018 lokhudza PFAS mu zodzoladzola, lochitidwa ndi Environmental Protection Agency ku Denmark, lidatsimikiza kuti "kuyeza kwa PFCA [mtundu wa PFAS] muzodzikongoletsera sikukhala pachiwopsezo kwa ogula." Koma pazovuta kwambiri - zomwe olembawo sizowona kwenikweni - pamenepo akhoza khalani pachiwopsezo ngati zodzoladzola zingapo zomwe zili ndi PFAS zigwiritsidwa ntchito nthawi imodzi.

TL; DR: "Chifukwa chakuti chidziwitso chonse ndi chochepa, sizingachitike," akutero Dr. Garshick. "Kafukufuku wowonjezereka amafunikira kuti muwone kuchuluka kwa PFAS yomwe imapezeka mu zodzoladzola, kuchuluka kwa mayikidwe kudzera pakhungu, komanso zoopsa zathanzi zomwe zimakhudzana ndi izi."

Ngakhale kuvulaza komwe kungachitike kwa PFAS mu zodzoladzola kudakali mlengalenga, pali njira zomwe mungatenge kuti muchepetse kuwonekera kwanu. EWG, yomwe sinagwire nawo phunziroli, ikulimbikitsa kuti muwone Database Deepin, yomwe imapereka mndandanda wazowonjezera ndi ziwonetsero zachitetezo pazodzola pafupifupi 75,000 ndi zinthu zosamalira anthu - kuphatikiza 300+ omwe ofufuza a EWG adazindikira kuti ali ndi PFAS, musanawonjezere zogulitsa zokongola. Chofunika kwambiri, mutha kuyitanitsa mamembala anu a congress ndikulimbikitsa malamulo omwe amaletsa PFAS mu zodzoladzola, monga No PFAS in Cosmetics Act yomwe yatulutsidwa dzulo ndi a Senator a Susan Collins ndi Richard Blumenthal.

Ndipo ngati mudakali ndi nkhawa, palibe cholakwika ndi kupita kapena naturel zabwino, ku la Alicia Keys.
