Nga āhuatanga take ranei me ngā āhuatanga pūtaiao o te metile mercaptan
Ko te metile mercaptan (74-93-1) he mea tōpūtōpu nui, he mea whakatae hauora. He hāpori kiriwhero ia i te wā e rahi ana te marokura, he wai kiriwhero i te wā hīkaro iti, he hau whakapiki nui e pānui ana ki te kāpē kua mate. He mea kaea, kore rawa i te āwhina i te wai, ā, āwhinatia e ngā paihere take.
Ngā whakamahi o te metile mercaptan
Ka taea e te metile mercaptan te hanga i ngā paihere matua mō ngā pepa whakamahue (pērā i ngā pepa whakamahue inuka me te fenthion, ngā pepa taruke cypermethrin me te promethazine), ngā rongoā (pērā i te methionine, lysine me te tryptophan), ngā paihere, ngā tuhinga whakamahere mō te kuku uru, ngā kaiwhakatū papatea, ngā kaiwhakaawe i te wai, ngā kaiwhakarite i te whakamarino, ngā kaiwhakakaha i te whakapū, ngā kaiwhakatika, ngā kaiwhakatū i te wai kaiwhakamahana, ngā kaiwhakamate hau, ārā
Ngā paheko o te metile mercaptan
Ko tana kohu he whanonga hīmanga, e pānui ana ki te H2S, ā, kei te take anesetiki i ngā konohi nui. I muri i te hākari i te nui o ngā kohu i whakaputaua, ka āwhina te take nei i te tangata ki te tahū i te rongo-ā-tauira, e whai ana i te kakano-kura, te takirua, te makiri, te kino i te upoko, me te kino i te puku; ko ngā wā nui ka take haere ki te mate i ngā pukapuka, mate i ngā kāwhatitanga, ā, ko te kino nui ka mate i te hākari i te rongo-ā-tauira. Ka take te whakaaweake i runga i te matawhāiti, ā, ka whakaae te take nei ki te whakarerekē i te kōpū, ā, ka mate i te kino i te kōpū, te kino i te kāwhatitanga, ā, ka whakatupu te kino i te whenua.
Ka take te whakapae i te ahi, ngā huawhenua nui, ā, ngā whakatakoto whakamahaki i te whakapae; ka puta te mahara i te kino i te whakapae sulfur oxide (SO2) i te whakapae; ka take te whakapae i te hanga i te porowhā, ā, ka whakaae te take nei ki te whakapae i te kōrero, ā, ka kitea te kino i te whakapae i te kōrero. Ka take te whakapae i te kino me te whakapae i te hākari i te wai me te whakapae i te kino.
Ko te metile mercaptan he whakawhitinga hauora mahi rite i tō tātou whenua. Ki te ture GBZ2.1-2019, ko tana rohe whakaaetanga mahi he waenganui wā kawe e taea ana te whakarite i 1 mg/m3. He mea kore te MAC me te PC-STEL, ko te pūtake hauora kino nui ko te whakatata ki te kikokiko.
I te wā e haere ai ngā mahi ki te wāhi o te metile mercaptan, me whakanuitia ngā āhuatanga whakamahara mo te tinana, pērā i ngā kākahu mahi whakapūmau hei whakamutunga i te makariri i te kiri, me ngā karu horahanga rākau hei whakamutunga i te pāpūnga i ngā karu, kia kaua e kitea te whakapā mai ki ngā kōpūroa. Tirohia inā kitea e koe i te wai ranei, i te kaiwhakaoti ranei ngā kākahu, me whakarerekētia atu i te maha o te haurangi.
Purongo Whakapakoko
Ka taea te tirotiro me te whakariterite i te tono raranga hāpai, ka tukuna hei āhua rākau rānei pērā i te 4L/8L/10L/40L.
