Mabotolo apulasitiki ofewa amaviika mazana a mankhwala m'madzi akumwa

Kafukufuku waposachedwapa wadzutsa machenjezo okhudza thanzi la madzi akumwa kuchokera m'mabotolo apulasitiki, ndipo asayansi akuda nkhawa kuti mankhwala omwe amalowa mumadzimadzi angakhale ndi zotsatira zosadziwika pa thanzi laumunthu. amamasula m'madzi ndipo chifukwa chake kuwadutsa mu chotsukira mbale kungakhale lingaliro loipa.
Kafukufukuyu, wochitidwa ndi ofufuza a ku yunivesite ya Copenhagen, adaganizira za mitundu ya mabotolo ofewa ofewa omwe amagwiritsidwa ntchito pamasewera. amasamukira m'madzi akumwa omwe ali nawo, motero adayesa kudzaza mipata ina.
Mabotolo a zakumwa zonse zatsopano komanso zogwiritsidwa ntchito kwambiri anadzazidwa ndi madzi apampopi nthawi zonse ndipo anasiya kukhala kwa maola 24 asanayambe komanso atatha kudutsa makina otsuka mbale. pambuyo rinses asanu ndi madzi apampopi.
"Ndi chinthu cha sopo pamwamba chomwe chinatulutsa kwambiri pambuyo potsuka makina," anatero wolemba mabuku wamkulu Selina Tisler. "Makhemikolo ambiri a m'botolo lamadzi pawokha akadalipo pambuyo pa kuchapa ndi makina owonjezera. Zinthu zapoizoni kwambiri zomwe tidapeza zidapangidwa botolo lamadzi litayikidwa mu chotsukira mbale - mwina chifukwa kutsuka kumawononga pulasitiki, zomwe zimachulukitsa kukhetsa. ”
Asayansi anapeza zinthu zoposa 400 zosiyanasiyana m’madzi kuchokera ku zipangizo zapulasitiki, ndi zinthu zoposa 3,500 zochokera ku sopo wotsukira mbale. chiwopsezo chawo sichidziwika.
"Tinadabwa ndi kuchuluka kwa mankhwala opezeka m'madzi pambuyo pa maola 24 mu botolo," anatero wolemba kafukufuku Jan H. Christensen. "Muli zinthu zambiri m'madzi - kuphatikiza zinthu zomwe sizinapezekepo m'mapulasitiki, komanso zinthu zomwe zingawononge thanzi. Pambuyo pa makina otsuka mbale, pali zinthu zambirimbiri.
Zinthu zomwe asayansi adazipeza moyesera zinaphatikizapo ma photoinitiators, mamolekyu omwe amadziwika kuti ali ndi poizoni pa zamoyo, zomwe zingathe kukhala carcinogens ndi endocrine disruptors.Anapezanso zofewa za pulasitiki, antioxidants ndi nkhungu zomwe zimagwiritsidwa ntchito popanga pulasitiki, komanso diethyltoluidine (DEET), chofala kwambiri mu mankhwala othamangitsa udzudzu.
Asayansi akukhulupirira kuti ndi zinthu zochepa chabe zomwe zapezeka zomwe zidawonjezedwa mwadala m'mabotolowo panthawi yopanga. Zambiri mwazo zitha kukhala zidapangidwa panthawi yogwiritsidwa ntchito kapena kupanga, pomwe chinthu china chikhoza kusinthidwa kukhala china, monga chofewa chapulasitiki chomwe amakayikira. idzasinthidwa kukhala DEET ikatsika.
Tissler anati: “Koma ngakhale ndi zinthu zodziŵika zimene opanga amaziwonjezera mwadala, ndi kawopsedwe kakang’ono chabe kamene kanaphunziridwa,” anatero Tissler.” Chotero, monga wogula, simudziŵa ngati pali wina aliyense amene angawononge thanzi lanu. .”
Kafukufukuyu akuwonjezera kafukufuku wochuluka wa momwe anthu amagwiritsira ntchito mankhwala ochuluka kwambiri pogwiritsa ntchito mankhwala apulasitiki, ndikuwonetsanso zambiri zomwe sizikudziwika m'munda.
Christensen anati: “Tikuda nkhaŵa kwambiri ndi kuchepa kwa mankhwala ophera tizilombo m’madzi akumwa.” Koma tikathira madzi m’chidebe kuti timwe, ife enife sitizengereza kuwonjezera mazana kapena masauzande a zinthu m’madzimo. Ngakhale sitingathe kunena ngati zinthu zomwe zili mu botolo logwiritsidwanso ntchito zikhudza thanzi lathu, koma ndigwiritsa ntchito galasi kapena botolo lachitsulo chosapanga dzimbiri mtsogolomu.
