Intshayelelo
Kwixesha lanamhlanje lempilo kunye nokukhuselwa kwendalo, abantu baya beqaphela ngakumbi malunga nokukhethwa kweemveliso zasekhitshini. Phakathi kwazo, iimveliso zasekhitshini ezingenayo i-PBA (i-bisphenol A) ngokuthe ngcembe zibe lukhetho lokuqala lwabathengi. I-PBA yikhemikhali efumaneka ngokubanzi kwiimveliso zeplastiki, kwaye iingozi zayo zempilo ezinokubakho kunye neempembelelo zokusingqongileyo ziye zatsala ingqalelo enkulu. Eli nqaku liza kuphonononga iingenelo zokusebenzisa iimveliso zasekhitshini ezingenayo i-PBA ngobunzulu, kwaye licacise ngazo ukusuka kwimiba emininzi efana nempilo, ukhuseleko lokusingqongileyo kunye nomgangatho.
2. Iingozi ezinokwenzeka ze-PBA
(I) Impembelelo kwimpilo yabantu
Ukuphazamiseka kwe-Endocrine
I-PBA ithathwa njengesiphazamisi se-endocrine kwaye inokuphazamisa inkqubo ye-endocrine yomntu. Inkqubo ye-endocrine inoxanduva lokulawula imisebenzi eyahlukeneyo yomzimba, kubandakanya ukukhula kunye nophuhliso, imetabolism, kunye nokuzala. Ukuvezwa kwexesha elide kwi-PBA kunokubangela ukuphazamiseka kwe-endocrine kwaye kuchaphazele imisebenzi eqhelekileyo yomzimba womntu.
Uphononongo lubonise ukuba i-PBA inokudityaniswa nokuvela kwezifo ezithile, ezinjengokutyeba, isifo seswekile, kunye nesifo sentliziyo. Nangona kungekho bungqina obucacileyo bokuba i-PBA ibangela ngokuthe ngqo ezi zifo, umphumo wayo ophazamisayo kwinkqubo ye-endocrine inokunyusa umngcipheko wesifo.
Ubuthi bokuzala
I-PBA nayo ineengozi ezinokubakho kwinkqubo yokuzala. Uvavanyo lwezilwanyana lubonisa ukuba izilwanyana ezivezwe kwi-PBA zinokuba neengxaki ezinjengokukhula okungaqhelekanga kwamalungu okuzala kunye nokuncipha kwamandla okuzala. Kubantu, abasetyhini abakhulelweyo kunye neentsana ngawona maqela asesichengeni kwi-PBA.
I-PBA kwabasetyhini abakhulelweyo inokudluliselwa kwi-fetus ngokusebenzisa i-placenta, enokuthi ichaphazele ukukhula kunye nophuhliso lwe-fetus. Iintsana zinovelwano ngakumbi kwi-PBA kuba amajoni azo omzimba kunye namalungu omzimba akakakhuli ngokupheleleyo. Ukuvezwa kwexesha elide kwi-PBA kunokuchaphazela uphuhliso lwenkqubo yokuzala yeentsana kwaye kunokukhokelela kwiingxaki ezifana nokufikisa kwangaphambili.
Iimpembelelo kwinkqubo ye-nervous
I-PBA inokuba nemiphumo emibi kwinkqubo ye-nervous. Olunye uphononongo lufumanise ukuba izilwanyana ezivezwe kwi-PBA zinokuba nokuziphatha okungaqhelekanga, ukuhla kwesakhono sokufunda, ukulahlekelwa yinkumbulo kunye nezinye iingxaki. Kubantu, ukuvezwa kwexesha elide kwi-PBA kunokunyusa umngcipheko wezifo ze-neurological ezifana nesifo sika-Parkinson kunye nesifo se-Alzheimer.
(II) Impembelelo kokusingqongileyo
Kunzima ukuthoba isidima
I-PBA yikhemikhali enzima ukuthotywa kwaye ingaba khona ixesha elide kwindawo yendalo. Oku kuthetha ukuba i-PBA iya kuqhubeka iqokelelana kwimo engqongileyo kwaye ibe nefuthe lexesha elide kwindalo esingqongileyo.
Xa iimveliso zeplastiki eziqulethe i-PBA zilahlwa, zinokungena emhlabeni, amanzi kunye nezinye iindawo. Emhlabeni, i-PBA inokuchaphazela ukuchuma kunye ne-microbial yoluntu emhlabeni, kwaye ibe nefuthe elibi ekukhuleni kwezityalo. Emanzini, i-PBA inokufunxwa zizidalwa zasemanzini, isasazwe ngekhonkco lokutya, kwaye ekugqibeleni ichaphazele impilo yabantu.
Ikhonkco lokutya elingcolileyo
I-PBA inokosulela ngekhonkco lokutya, nto leyo ebangela iimpembelelo ezixhaphakileyo kwi-ecosystem. Izinto eziphilayo zasemanzini ezifana nentlanzi kunye ne-shellfish zinokufunxa i-PBA emanzini, enokuthi ityiwe ngabantu. Ukongeza, izityalo zinokufunxa i-PBA emhlabeni kwaye zingene kwikhonkco lokutya kwabantu.
Ukutya kwexesha elide okuqulethe i-PBA kunokukhokelela ekuqokeleleni umxholo we-PBA emzimbeni womntu, ukwandisa ingozi yempilo. Kwangaxeshanye, i-PBA inokuba neziphumo ezibi kwezinye izinto eziphilayo kwi-ecosystem kwaye itshabalalise ibhalansi ye-ikholoji.
