Waikura etirenaHe matū waro te matū nei, ko tōna tauira matū ko C2H4O, he hau mura horihori. Ina tino teitei tōna kukū, ka puta he reka.Waikura etirenahe ngāwari te wairewa ki te wai, ā, ka puta he iti noa te waikura etilena ina tahuna te tupeka. He iti noa tewaikura etireneka kitea i roto i te taiao.

Ko te ethylene oxide te nuinga o te wā e whakamahia ana hei hanga i te ethylene glycol, he matū e whakamahia ana hei hanga i te anti-huka me te polyester. Ka taea hoki te whakamahi i roto i ngā hōhipera me ngā whare patu huakita hei patu huakita i ngā taputapu me ngā taonga hauora; Ka whakamahia hoki mō te patu huakita kai me te whakahaere i ngā pepeke i roto i ētahi hua ahuwhenua kua rongoatia (pēnei i ngā mea kakara me ngā otaota).

Te pānga o te ethylene oxide ki te hauora

Te pānga poto o ngā kaimahi ki ngā kukū tiketike o tewaikura etirenei te rangi (te nuinga o te wā he tekau mano ngā wā i tērā o te tangata noa) ka whakaoho i ngā pukahukahu. Ko ngā kaimahi e pāngia ana e te nui o tewaikura etirenemō te wā poto me te wā roa, tērā pea ka pāngia koe e te ānini, te ngaro o te mahara, te ngoikore, te whakapairuaki me te ruaki.

Kua kitea e ngā rangahau he nui ngā kukū o te waikawa i roto i ngā wahine hapuwaikura etirenei te wāhi mahi ka pāngia ētahi wāhine e te mate whānau. Kāore i kitea e tētahi atu rangahau tētahi atu pānga pēnei. Me nui ake ngā rangahau hei mārama ki ngā mōrearea o te pānga i te wā e hapu ana.

Ka manawa ētahi kararehewaikura etireneme te kukū tino teitei i roto i te taiao (10000 ngā wā teitei ake i te hau o waho) mō te wā roa (ngā marama ki ngā tau), ka whakaoho i te ihu, te waha me ngā pukahukahu; Kei reira anō ngā pānga neurological me te whanaketanga, tae atu ki ngā raruraru uri tāne. Ko ētahi kararehe i hongi i te ethylene oxide mō ētahi marama i pāngia e te mate tākihi me te anemia (te hekenga o te maha o ngā pūtau toto whero).

He pēhea te tūponotanga ka puta te mate pukupuku i te ethylene oxide?

Ko ngā kaimahi e tino pāngia ana, me te roanga o te wā pāngia mō te neke atu i te 10 tau, he nui ake te tūponotanga ki te pāngia e ētahi momo mate pukupuku, pērā i ētahi mate pukupuku toto me te mate pukupuku ū. Kua kitea anō hoki ngā mate pukupuku rite i roto i ngā rangahau kararehe. Kua whakatauhia e te Tari Hauora me ngā Ratonga Tangata (DHHS)waikura etirenehe mate pukupuku e mōhiotia ana mō te tangata. Kua whakatau te Tari Tiaki Taiao o Amerika he pānga pukupuku te manawa o te ethylene oxide ki te tangata.

Me pēhea te whakaiti i te mōrearea o te pānga ki te ethylene oxide

Me mau ngā kaimahi i ngā mōhiti tiaki, i ngā kākahu me ngā karapu i te wā e whakamahi ana, e hanga ana rāneiwaikura etirene, ā, me mau i ngā taputapu tiaki manawa ina hiahiatia.
