2. Ka hopena i ke kaiapuni.

i. pōʻino olakino

Alanui o ka invasion: inhalation, ingestion.
Nā pōʻino olakino: ʻAʻohe mea ʻawaʻawa ka metala Barium. ʻO nā paʻakai barium hiki ke hoʻoheheʻe ʻia e like me ka barium chloride, ka barium nitrate, a me nā mea ʻē aʻe. , ke komo ʻana o ka myocardial, a me ka pāhaʻi koko haʻahaʻa. ʻO ka maʻi lolo a me ka pōʻino o ka myocardial hiki ke alakaʻi i ka make. ʻO ka inhalation o ka lepo hoʻoheheʻe barium hiki ke hoʻoulu i ka ʻawaʻawa barium, ua like ka hana me ka ʻawaʻawa waha, akā ʻoi aku ka maʻalahi o ka hopena o ka digestive tract. ʻO ka hoʻolaha lōʻihi i nā pūhui barium hiki ke hoʻoulu i ka salivation, nāwaliwali, pōkole o ka hanu, pehu a me ka ʻāʻī ʻana o ka mucosa waha, rhinitis, tachycardia, hoʻonui i ke koko a me ka lauoho lauoho. ʻO ka inhalation lōʻihi o ka lepo pūhui barium insoluble, e like me ka barium sulfate, hiki ke hana i ka barium pneumoconiosis.

ii. ʻike toxicological a me ka hana kaiapuni

ʻO nā hiʻohiʻona pōʻino: haʻahaʻa haʻahaʻa kemika, hiki ke hoʻopau koke i ka ea i ka wā i wela ai a hiki i ke ʻano hoʻoheheʻe, akā hiki ke wela ka lepo ma ka lumi wela. Hiki iā ia ke hoʻoulu a pahū ke ʻike ʻia i ka wela, ka lapalapa a i ʻole ka hopena kemika. I ka hoʻopili ʻana me ka wai a i ʻole ka waiʻakika, hana ʻino ʻo ia a hoʻokuʻu i ke kinoea hydrogen i mea e hoʻopau ai. I ka hui ʻana me ka fluorine, chlorine, a me nā mea ʻē aʻe, e kū mai kahi hopena kemika ikaika. Ke hoʻopili ʻia me ka ʻakika a i ʻole ka waika dilute, e hoʻohuhū a pahū.
Huahana (decomposition): barium oxide.

3. ʻO nā ʻano hana nānā pilikia ma ka pūnaewele.

　

4. Nā ʻano hana nānā keʻena hana.

Potentiometric titration (GB/T14671-93, maikaʻi wai)
ʻO ke ʻano hoʻoheheʻe atomika (GB/T15506-95, ka maikaʻi o ka wai)
ʻO ka manuale no ka hoʻāʻo ʻana a me ka loiloi o nā ʻōpala paʻa, unuhi ʻia e Kina Environmental Monitoring General Station a me nā mea ʻē aʻe.

5. Nā kūlana kaiapuni.

ʻO ka Soviet Union mua	ʻO ka nui o ka ʻae ʻia o nā mea ʻino i loko o ka ea hale hana	0.5mg/m3
Kina (GB/T114848-93)	Kūlana maikaʻi o ka wai lepo (mg/L)	Papa I 0.01; Papa II 0.1; Papa III 1.0; Papa IV 4.0; Papa V ma luna o 4.0
Kina (e kau ʻia)	ʻO ka nui o ka ʻae ʻia o nā mea pōʻino i loko o nā kumu wai inu	0.7mg/L

6. ʻO ka mālama ʻana i ka pilikia a me nā hana hoʻopau.

i. pane ulia pōpilikia i nā kahe

E hoʻokaʻawale i nā wahi i hoʻohaumia ʻia a hoʻokaʻawale i ke komo ʻana. E ʻoki i ke kumu o ke ahi. Paipai ʻia nā limahana ulia pōpilikia e ʻaʻahu iā lākou iho i nā maka lepo kānana a me nā lole pale ahi. Mai hoʻopili pololei me ka ʻōpala. Liʻiliʻi liʻiliʻi: E pale i ka hoʻoulu ʻana i ka lepo a hōʻiliʻili i loko o nā pahu maloʻo, maʻemaʻe, uhi ʻia me kahi koʻi maʻemaʻe. Hoʻololi no ka hana hou ʻana. Nā ʻōpala nui: E uhi ʻia me ka ʻili pepa a i ʻole ke kāwele e hōʻemi i ka hoʻopuehu ʻana. E hoʻohana i nā mea hana ʻole e hoʻololi a hana hou.

ii. nā hana pale

Ka pale hanu: ʻAʻole koi ʻia kahi pale kūikawā, akā makemake ʻia e hoʻohana ʻia kahi pale huna huna hoʻomaʻemaʻe ponoʻī i nā kūlana kūikawā.
Pale maka: E hoʻohana i nā makaaniani palekana kemika.
Palekana kino: E ʻaʻahu i nā lole pale kemika.
Pale lima: E hoʻohana i nā mīkina lima.
ʻO nā mea ʻē aʻe: Ua pāpā loa ʻia ke puhi ʻana ma ke kahua hana. E nānā pono i ka hoʻomaʻemaʻe pilikino.

iii. nā hana kōkua mua

Hoʻopili i ka ʻili: Wehe i nā lole haumia a holoi pono i ka ʻili me ke kopa a me ka wai.
KA MAKA: E hāpai i ka lihilihi a holoi me ka wai kahe a i ʻole ka paʻakai. E ʻimi i ka lāʻau lapaʻau.
INHALATION: E hoʻoneʻe koke i ka ea hou mai ke kahua. E wehe i ke ala ea. Inā paʻakikī ka hanu, hāʻawi i ka oxygen. Inā pau ka hanu ʻana, hāʻawi koke i ka hanu ʻana. E ʻimi i ka lāʻau lapaʻau.
Ingestion: E inu nui i ka wai mehana, hoʻoulu i ka luaʻi, holoi ʻana i ka ʻōpū me 2%-5% solution sodium sulfate, a hoʻoulu i ka maʻi maʻi. E ʻimi i ka lāʻau lapaʻau.

Nā ʻano hana hoʻopau ahi: ka wai, ka hupa, carbon dioxide, halogenated hydrocarbons (e like me 1211 mea hoʻopau) a me nā mea hoʻopau ahi ʻē aʻe. Pono e hoʻohana ʻia ka pauda graphite maloʻo a i ʻole ka pauda maloʻo ʻē aʻe (e like me ke one maloʻo) e kinai i ke ahi.
