Te Hītori, Te Whakawhanaketanga, me te Mana o Naianei o te Sodium Cyanide

Kupu Whakataki

Ko te konutai cyanide (NaCN), he tote kore-ora tino paitini, kua whai wāhi nui ki ngā ahumahi mai i te keri maina ki ngā rongoā. E whai ana tēnei tuhinga i ōna pūtake hītori, e tūhura ana i tōna whanaketanga ahumahi, ā, e tirotiro ana i tōna tūranga o nāianei i roto i tētahi wā e aro ana ki te oranga tonutanga.

1. Nga Taketake o mua

I te waenganui o te rautau 19 i hangaia tuatahitia ai te konutai cyanide, ā, i te tīmatanga ka rongonui hei matū mō te tukatuka me te tango whakarewa . I puta tōna whanaketanga i roto i te rāngai keri koura, i reira ka noho hei mea nui mō te wehewehe i te koura me te hiriwa mai i te konganuku mā te tukanga cyanidation.

I te mutunga o te rau tau 1800, kua whakawhānuihia e te ahumahi te whakamahi ki:

• Te hanga waikano

• Te hanga rapa waihanga

• Te whanaketanga pesticide

  
  

  
  

2. Te Putanga o te Rautau 20

Ahakoa i hiahiatia he tikanga haumaru tino pakari nā te paitini o te Konutai Cyanide , i whānuitia te whakamahinga o tēnei mea:

Tono Nui

1. Te Keri : Koia tonu te whakamahinga matua mō te tango koura, ā, nā tēnei i taea ai te tango pai i ngā konganuku iti te kounga.

2. Matū Waro : Ka whakamahia hei whakakorikori, hei takawaenga rānei i roto i ngā tauhohenga pēnei i te hanga nitrile.

3. Rongoā : Whakamahia hei hanga rongoā pēnei i te acetazolamide (he diuretic).

Ka Puta Nga Maharahara Ture

Ko te tipu haere o te mohiotanga mo ona mate taiao me te hauora i arai ki:

• Ture : I whakatinanahia e ngā whenua pēnei i te US me Kānata ngā ture tino kaha ake mō te rokiroki, te kawe, me te whakakorenga para.

• Paerewa Ahumahi : Te whakamahi i ngā anga haumaru hei whakaiti i te tūponotanga o te pānga.

3. Whenua o naianei (Rautau 21)

I ēnei rā, ko te tūranga o te konutai cyanide e whakapūmautia ana e ngā whāinga pumau me te auahatanga hangarau:

1. Hangarau rereke

• Te Keri Kakariki : Ko te rangahau mō ngā whakakapinga kore-paitini (hei tauira, te tango thiosulfate) e whai ana ki te whakaiti i te whakawhirinaki ki te cyanide.

• Ngā Huarahi Whakakapi-koiora : Te whakawhanaketanga o ngā kaitāpiri chelating e pai ana ki te taiao mō te tango whakarewa.

2. Nga Ture Kaha

• Te Whakatutukitanga o te Ao : Ka whakatinanahia e ngā iwi ngā paerewa ISO 14001 me REACH hei whakaiti i ngā kino ki te taiao.

• Aroturuki Mamati : Mā ngā taputapu Poraka mekameka me te IoT ka pai ake te māramatanga o te mekameka tuku.

3. Rangahau me te Matauranga

• Whakangungu Haumaru : Ngā kaupapa whakahau mō ngā kaimahi ahumahi e whakahaere ana i te NaCN.

• Ngā Kaupapa Mātauranga : Ka mahi tahi ngā whare wānanga me ngā ahumahi ki te tūhura i ngā tikanga whakahiato haumaru ake.

Opaniraa

Mai i tōna kitenga i te rautau 19 ki ōna whakamahinga o ēnei rā, he āhuatanga pōhēhē tonu te konutai cyanide : he taputapu ahumahi nui me ngā mōrearea kei roto. Ahakoa e whai ana ngā huarahi kē atu me ngā ture ki te whakaiti i tōna tapuwae taiao, ko tōna tūranga kore e taea te whakakapi i roto i ngā rāngai pēnei i te keri maina ka whakarite kia whakamahia tonutia - ahakoa he arotahi nui ki te haumaru me te pumau.
