Muhupenyu hwedu hwezuva nezuva, mabhodhoro epurasitiki anogona kuonekwa kwose kwose.Ndinoshamisika kana waona kuti kune nhamba yenhamba yakaita sechiratidzo chetatu pazasi pemabhodhoro epurasitiki mazhinji (makapu).
semuyenzaniso:
Mabhodhoro emvura ane mineral, akaiswa 1 pasi;
Makapu epurasitiki asingadziviriri ekugadzira tii, akaiswa 5 pasi;
Mabhodhoro e-instant noodles uye mabhokisi ezvokudya zvinokurumidza, pasi inoratidza 6;
…
Sezvo munhu wese anoziva, mavara ari pasi pemabhodhoro epurasitiki aya ane zvirevo zvakadzika, ane "toxicity code" yemabhodhoro epurasitiki uye anomiririra chiyero chekushandiswa kwezvigadzirwa zvepurasitiki zvinoenderana.
"Nhamba nemakodhi ari pasi pebhodhoro" chikamu chekuzivikanwa kwechigadzirwa chepurasitiki chakatarwa mumitemo yenyika:
Chiratidzo chekudzokorodza chetatu chiri pazasi pebhodhoro repurasitiki chinoratidza kudzokororwa, uye nhamba 1-7 dzinoratidza rudzi rweresin inoshandiswa mupurasitiki, zvichiita kuti zvive nyore uye nyore kuona zvinhu zvakajairika zvepurasitiki.

Ichi chinhu chinoshandiswa zvakanyanya, kunyanya mukugadzira mabhodhoro evana, makapu emuchadenga, nezvimwewo. Zvisinei, zvave zvichipesana mumakore achangopfuura nokuti ine bisphenol A;saka, chenjerera uye nyatsoteerera paunenge uchishandisa iyi chigadziko chepurasitiki.
Saka, mushure mekunzwisisa zvinorehwa neaya mavara epurasitiki, maitiro ekutsemura iyo "toxicity code" yemapurasitiki?
4 toxicity yekuona nzira
(1) Kuongororwa kwekunzwa
Mabhegi epurasitiki asina muchetura machena emukaka, anopenya, kana asina ruvara uye akajeka, anochinjika, anotsvedzerera pakubata, uye anoita kunge ane wakisi pamusoro;Mabhegi epurasitiki ane muchetura ane tsvina kana kuti akajeka eyero muruvara uye anonzwa kunamira.
(2) Kuonekwa kwejitter
Bata imwe magumo epurasitiki uye uizununguse nesimba.Kana ichiita ruzha, haizi uturu;kana ikaita isinganzwisisi zvakanaka, ine muchetura.
(3) Kuedza mvura
Isa bhegi repurasitiki mumvura uye uiise pasi.Iyo isiri-chepfu yepurasitiki bhegi ine diki chaiyo giravhiti uye inogona kuyangarara pamusoro.Chibhegi chepurasitiki chine chepfu chine giravhiti yakakura uye inonyura.
(4) Kuonekwa kwemoto
Non-chepfu polyethylene epurasitiki mabhegi anogona kutsva, ane bhuruu marimi uye yero pamusoro.Pakutsva, dzinodonha semisodzi yekenduru, kunhuwa kweparafini, uye dzinobudisa utsi hushoma.Toxic polyvinyl chloride mabhegi epurasitiki haabatike uye anodzima kana angobviswa mumoto.Iyo yero ine pazasi yakasvibirira, inogona kuita tambo kana yakapfava, uye ine kunhuhwirira kwakanyanya kwehydrochloric acid.
