Hei whakarewa waro whai hua, ā, he whānui te whakamahinga, he whānui te whakamahinga o te n-hexane i roto i ngā tukatuka ahumahi, ngā mahi hanga māmā, me te tukatuka kai mō te horoi, te tango, te piri me ētahi atu tikanga. Heoi, he iti tonu te māramatanga o te marea mō te n-hexane, ā, he hē tonu. He maha ngā tāngata e whakaiti ana i tō rātou tūpato nā te mea kua tapaina ko "iti-paitini", engari he take huna ia mō te paitini mahi. Hei āwhina i te marea kia karo i ngā tūponotanga pūtaiao, ka whakautua e tēnei tuhinga ngā pātai noa mō te n-hexane, ā, ka whakamāramahia ngā whakaaro hē noa.
P1: He aha te take he matū tino mōrearea te n-hexane mō te hauora mahi ahakoa tōna iti o te paitini?
He rerekē ki ngā matū tino paitini pērā i te formaldehyde me te benzene, kāore he tohu paitini e kitea ana i roto i te n-hexane i muri i te pānga i ētahi wā, i ētahi wā iti noa iho rānei, ā, koinei te take e kore ai e arohia ngā tūponotanga. I roto i te ao matū, he wai mārama, he iti te paitini o te n-hexane, he kore tae, he kakara ngoikore, he tere hoki te rere i te pāmahana rūma. Ka uru ki te tinana tangata mā te manawa manawa me te pa ki te kiri.
Ko tōna āhuatanga tino mōrearea kote paitini whakaemi. Ka āta haere te tinana tangata ki te whakapūngao i te n-hexane; ki te roa te wā ka iti te kukū o te matū, ka piki haere te nui o ngā paitini, ā, ka kino haere tonu ngā io o te taha. Hei tāpiri, he tino mura te n-hexane. Ka taea e tōna kohu te hanga ranunga pahū me te hau, ā, ka puta he mura, he pahū rānei ina pāngia e ngā mura tuwhera, e ngā pāmahana teitei rānei. Nā te mea he paitini, he mura hoki, he tino whakahaeretia i roto i te whakahaere hauora mahi.
P2: Kei hea te wāhi e kitea whānuitia ai te n-hexane? Me mataara rānei te iwi noa?
He whānuitia te whakamahinga o te N-hexane i roto i ngā ahumahi ahumahi me te kai, ā, ko ngā kaimahi o te rārangi mua te hunga e tino tūpono ana ki te pānga kino. I roto i ngā āhuatanga ahumahi, he mea noa te whakamahi i roto i te huihuinga hiko, te tango hinu i ngā taputapu, te tukatuka hiako, te hanga hu me te tā hei tango hinu, te whakaranu kāpia me te whakaranu waituhi.
I roto i te umanga kai, ka whakamahia te n-hexane kounga kai hei tango i ngā hinu huawhenua pērā i te hinu pīni soya me te hinu rēpī. Ka whakaitihia ngā toenga mā roto i ngā tukanga whakamahine, ā, ka tutuki katoa ki ngā paerewa haumaru ā-motu, kia haumaru ai te kai o ia rā mā te marea. He iti noa iho te pānga o te tangata noa ki te oranga o ia rā, ā, me karo noa i ngā hua kāpia ngoikore me ngā hopi horoi kāore i te tino tika, me te kore e manukanuka nui.
Q3: He aha ngā tohu noa o te paihana n-hexane, ā, me pēhea te wehewehe i aua tohu mai i te ngenge noa?
Kua wehea te paihana N-hexane ki te mamae nui i te wā e pāngia ana, me te paihana roa e whakaemihia ana, ā, he nui ake te kino o tēnei paihana whakamutunga. Mā te manawa poto i te kohu n-hexane nui ka pā te whanoke, te whakapairuaki, te ngenge, te hiamoe me te kikī o te uma. He rite ēnei tohu ki te ngenge, te werawera rānei, ā, ka ngāwari te wareware, engari ka memeha haere i muri i te wehenga atu i te taiao poke.
He tino tinihanga te paihana mau tonu i puta mai i te whakamahinga roa me te kore tiaki. Ko ngā tohu tōmua ko te ngoikore o ngā pito o ngā maihao, te ngoikore o te aro ki ngā mea e pā ana, me te ngoikore o ngā waewae, e pohehetia ana mō te ngenge noa. I te kohikohinga o ngā paitini, ka pāngia pea ngā tūroro e te mamae haere o ngā uaua, te ngoikore whānui, me te horapa o te ngoikore. I ngā wā kino ka puta te neuritis peripheral, ka hua ake te ngoikore o te uaua me te ngoikore o te mahi nekeneke. He uaua ki te whakatika i te kino o ngā io, ā, me roa te wā whakaora. Ka pakaru hoki te ārai kiri i te pa atu ki te kiri mō te wā roa, ka maroke, ka pakaru, ka pā te kiri kiri.
P4: Me pēhea e taea ai e ngā kaimahi o te rārangi mua te whakatutuki i te tiakitanga pūtaiao? He aha ngā mātāpono matua?
Ka taea te ārai i ngā tūponotanga N-hexane mā te tiaki paerewa, e aro ana ki te hauhautanga, te tiaki whaiaro me te whakahaere hauora. Tuatahi, me pupuri e ngā wāhi mahi te hauhautanga whānui me ngā taputapu whakaputa pai hei whakawai i te kohu n-hexane pūngāwerewere me te ārai i te nui rawa o te kukū.
Tuarua, me mau ngā kaimahi i ngā kopare hau, i ngā karapu rapa ātete-wairewa, me ngā mōhiti tiaki i te wā e mahi ana. Kāore e whakaaetia te pa atu ki te kiri me te manawa tata ki te kohu. I taua wā, me whakatinana ngā ture haumaru ahi tino kaha; kāore e whakaaetia te mura tuwhera me te whakamahana pāmahana teitei i roto i ngā wāhi mahi hei whakakore i ngā tūponotanga mura me ngā tūponotanga pahū. Tuatoru, he mea nui ngā whakamātautau hauora mahi auau mō ngā kaimahi roa kia kitea wawe ai ngā kino o te io, kia taea ai te wawaotanga me te maimoatanga i te wā tika.
Q5: He aha ngā tapu matua mō te rokiroki me te whakakorenga ohorere o te n-hexane?
Me tutuki te rokiroki N-hexane i ngā ture matū morearea. Me hiritia kia mau, ā, me rongoa ki roto i tētahi whare putunga hauhautanga, hauhautanga, kia matara atu i ngā pūtake wera me ngā mura tuwhera, me te karo i te pānga ki te pāmahana teitei. Me rongoa motuhake, kaua rawa e whakaranua ki ngā waikura, ngā waikawa, ngā kawakore rānei hei ārai i ngā tauhohenga matū morearea. Kāore e whakaaetia ngā ipu kirihou me ngā ipu rapa, nā te mea ka waikura pea ngā ipu n-hexane, ka turuturu hoki.
Me whai maimoatanga ohorere paerewa mēnā ka pāngia koe e te mate. Me horoi pai ngā wāhi e pā ana ki te kiri ki te hopi me te wai rere. Me horoi tonu ngā kanohi ki te wai, ā, me whai maimoatanga hauora i muri mai. Me neke tonu te hunga e pāngia ana e te mamae o te manawa ki te hau hou, ā, me whiwhi awhina hauora wawe mēnā he kino ngā tohu. Kaua rawa ngā tāngata e horomia ana e ruaki kia kore ai e pāngia e te niumōnia manawa, ā, me rapu awhina hauora tere. Hei whakarāpopototanga, ko ngā mōrearea n-hexane ka puta mai i te whakamahinga kore-paerewa. Mā te mōhio ki te mōhiotanga haumaru me te whai i ngā ture tiaki ka taea te karo i ngā mōrearea huna me te whakarite i te haumaru o te wāhi mahi.
