Monga chimodzi mwazinthu zazikulu zamagalasi, mabotolo ndi zitini ndizodziwika bwino komanso zotengera zomwe mumakonda. M'zaka zaposachedwa, ndi chitukuko chaukadaulo wamafakitale, zida zosiyanasiyana zomangira zatsopano monga mapulasitiki, zida zophatikizika, mapepala apadera oyikapo, tinplate, ndi zojambulazo za aluminiyamu zapangidwa. Zoyikapo magalasi zimapikisana kwambiri ndi zida zina zopakira. Chifukwa mabotolo agalasi ndi zitini zimakhala ndi ubwino wowonekera, kukhazikika kwa mankhwala, mtengo wotsika, maonekedwe okongola, kupanga kosavuta ndi kupanga, ndipo amatha kubwezeretsedwanso ndikugwiritsidwa ntchito nthawi zambiri, ngakhale atakumana ndi mpikisano kuchokera kuzinthu zina zoyikapo, mabotolo agalasi ndi zitini akadali. kukhala ndi zida zina zopakira zomwe sizingasinthidwe. zapaderazi.
M'zaka zaposachedwa, pazaka zopitilira khumi zakuchita moyo, anthu apeza kuti mafuta odyedwa, vinyo, viniga ndi msuzi wa soya m'migolo ya pulasitiki (mabotolo) ndizovulaza thanzi la munthu:
1. Gwiritsani ntchito ndowa zapulasitiki (mabotolo) kusunga mafuta odyedwa kwa nthawi yayitali. Mafuta odyedwa amasungunuka m'mapulasitiki owopsa m'thupi la munthu.
95% yamafuta odyedwa pamsika wapakhomo amadzaza m'mabotolo apulasitiki (mabotolo). Akasungidwa kwa nthawi yayitali (nthawi zambiri kupitilira sabata), mafuta odyedwa amasungunuka m'mapulasitiki ovulaza thupi la munthu. Akatswiri odziwa zapakhomo atenga mafuta a saladi ya soya, mafuta osakanikirana, ndi mafuta a mtedza m'migolo yapulasitiki (mabotolo) amitundu yosiyanasiyana komanso masiku osiyanasiyana afakitale pamsika kuti ayese. Zotsatira zoyeserera zikuwonetsa kuti migolo yonse yapulasitiki yoyesedwa (mabotolo) imakhala ndi mafuta odyedwa. Pulasitiki "Dibutyl phthalate".
Plasticizers ali ndi poizoni wina paubereki wa munthu, ndipo ndi poizoni kwambiri kwa amuna. Komabe, zotsatira zapoizoni za plasticizers ndi zosatha ndipo zimakhala zovuta kuzizindikira, kotero patatha zaka zoposa khumi za kukhalapo kwawo kofala, tsopano zakopa chidwi cha akatswiri apakhomo ndi akunja.
2. Vinyo, viniga, msuzi wa soya ndi zosakaniza zina mu migolo ya pulasitiki (mabotolo) zimaipitsidwa mosavuta ndi ethylene yomwe imavulaza anthu.
Migolo yapulasitiki (mabotolo) amapangidwa makamaka ndi zinthu monga polyethylene kapena polypropylene ndipo amawonjezeredwa ndi zosungunulira zosiyanasiyana. Zida ziwirizi, polyethylene ndi polypropylene, sizowopsa, ndipo zakumwa zam'chitini sizikhala ndi zotsatirapo zoyipa pathupi la munthu. Komabe, chifukwa mabotolo apulasitiki amakhalabe ndi ethylene monomer pang'ono panthawi yopanga, ngati zinthu zomwe zimasungunuka ndi mafuta monga vinyo ndi viniga zimasungidwa kwa nthawi yayitali, thupi ndi mankhwala zidzachitika, ndipo ethylene monomer idzasungunuka pang'onopang'ono. . Kuonjezera apo, migolo ya pulasitiki (mabotolo) amagwiritsidwa ntchito posungira vinyo, viniga, msuzi wa soya, ndi zina zotero, mumlengalenga, mabotolo apulasitiki adzakhala okalamba chifukwa cha mpweya, kuwala kwa ultraviolet, ndi zina zotero, kutulutsa ma monomers ambiri a vinyl, kupanga vinyo kusungidwa migolo (mabotolo) , Vinyo wosasa, soya msuzi ndi zowononga zina.
Kudya kwa nthawi yaitali chakudya chokhala ndi ethylene kungayambitse chizungulire, mutu, nseru, kusafuna kudya, ndi kukumbukira kukumbukira. Pazovuta kwambiri, zingayambitsenso kuchepa kwa magazi m'thupi.
Kuchokera pamwambapa, tinganene kuti ndi kusintha kosalekeza kwa anthu kufunafuna moyo wabwino, anthu azisamalira kwambiri chitetezo cha chakudya. Ndi kutchuka ndi kulowa kwa mabotolo agalasi ndi zitini, mabotolo agalasi ndi zitini ndi mtundu wa chidebe cholongedza chomwe chimapindulitsa pa thanzi laumunthu. Pang'onopang'ono idzakhala mgwirizano wa ogula ambiri, ndipo idzakhalanso mwayi watsopano wopanga mabotolo agalasi ndi zitini.
