Tsoka ilo, mafakitale amakono samakonza popanda kugwiritsa ntchito zoteteza. Anthu amachitapo kanthu mosiyana ndi zowonjezera zotere, wina amachitira mwachizolowezi, wina amakhala ndi vuto, komabe thupi limakhala lovulazidwa kwambiri.
Lero, chimodzi mwazinthu zotchuka kwambiri popanga zakudya ndi sulfure dioxide (E220). Izi zimateteza masamba, zipatso, zakumwa, zamzitini ndi zinthu zina zomwe zikufunikira masiku ano, kuchokera ku mabakiteriya osiyanasiyana, bowa ndi tizilombo toyambitsa matenda.
Zotsatira za sulfure dioxide m'thupi
Sulfure dioxide nthawi zambiri imapezeka m'masukiti, mu zakumwa zoledzeretsa, mumagwiritsidwe a masoseji, opangidwa ndi mankhwalawa ndi zipatso. Monga lamulo, E220 kulowa mu thupi laumunthu, mwamsanga imakanizidwa ndi kupambanitsidwa mu mkodzo, popanda kuwononga kuwononga kwa thanzi, koma zimachitika kuti sulfure dioxide imayambitsa mavuto aakulu, makamaka ngati chizolowezi chake chiloledwa chikupitirira.
Poyamba ndi kofunika kunena kuti kulowa m'mimba mwa E220 kumawononga vitamini B1, kuchepa kwa zomwe zimakhudza mkhalidwe waumunthu. Sulfure dioxide ingapangitse mphamvu zowonongeka komanso ngakhale zotupa za khansa.
Komanso, muyenera kusamalira ndi kusungira, anthu omwe ali ndi mtima wolephera, koma anthu omwe ali ndi mphumu zambiri ayenera kupewa kumwa E220, tk. Amatha kuyambitsa matenda otupa, omwe angathe kupha. Sulfure dioxide ikhoza kuchititsa kuwonjezeka kwa acidity ya madzi a m'mimba, omwe akhoza kukhala owopsa kwa iwo omwe ali ndi zilonda za m'mimba, gastritis kapena matenda ena akuluakulu a m'mimba.
Ndiponso, E220 ikhoza kuyambitsa poizoni, zizindikiro zake ndi izi:
- kusanza;
- coryza;
- chifuwa;
- kuphwanya ntchito za zipangizo zolankhula;
- kutsekula m'mimba;
- mutu;
- kupweteka mmimba;
- kuyaka mmero, ndi zina.
Pofuna kupewa zotsatira zonsezi, m'pofunika kugwiritsa ntchito mochepa momwe mungathere zakumwa za kaboni, mowa komanso zinthu zina zomwe zili ndi sulufule dioxide. Mbewu ndi zipatso ziyenera kutsukidwa bwino, ndiye mutha kuchotseratu E220, yomwe ikugwiritsidwa ntchito ndi mankhwalawa. Mwachitsanzo, sulfure dioxide yomwe imapezeka mu zipatso zouma ikhoza kuchotsedwa kwathunthu ngati nthawi zambiri imanyowa madzi, kenako imatsukidwa bwino.
