2. Ingaruka ku bidukikije.
i. ingaruka mbi ku buzima
Inzira yo gutera: guhumeka, kuribwa.
Ibyangiza ubuzima: Icyuma cya Barium ntago ari uburozi. Imyunyu ngugu ya bariyumu nka barium chloride, nitrate ya barium, nibindi (barium karubone ihura na aside gastricike kugirango ibeho chloride ya barium, ishobora kwinjizwa mu nzira yigifu) irashobora uburozi bukabije nyuma yo kuyifata, hamwe nibimenyetso byerekana uburibwe bwigifu, ubumuga bwimitsi igenda itera imbere , uruhare rwa myocardial, hamwe na potasiyumu yamaraso make. Ubumuga bwo mu myanya y'ubuhumekero no kwangirika kwa myocardial bishobora gutera urupfu. Guhumeka umukungugu wuzuye wa barium urashobora gutera uburozi bukabije bwa barium, imikorere isa nuburozi bwo mu kanwa, ariko inzira yigifu iroroha. Kumara igihe kinini kumubiri wa barium bishobora gutera amacandwe, intege nke, guhumeka neza, kubyimba no gutwarwa na mucosa yo mu kanwa, rhinite, tachycardia, kongera umuvuduko wamaraso no guta umusatsi. Guhumeka igihe kirekire cyumukungugu wa barium udashonga, nka barium sulfate, birashobora gutera barium pneumoconiose.
ii. amakuru yuburozi nimyitwarire y ibidukikije
Ibiranga akaga: reaction nkeya ya chimique, irashobora guhita yaka umwuka mugihe ushushe kugirango ushonge, ariko umukungugu urashobora gutwika ubushyuhe bwicyumba. Irashobora gutera umuriro no guturika iyo ihuye nubushyuhe, ibirimi cyangwa imiti. Iyo ihuye namazi cyangwa aside, irakara cyane ikarekura gaze ya hydrogène kugirango itere umuriro. Iyo uhuye na fluor, chlorine, nibindi, hazabaho reaction yimiti ikaze. Iyo ihuye na aside cyangwa aside aside, bizatera gutwikwa no guturika.
Ibicanwa (decomposition) ibicuruzwa: barium oxyde.
3. Uburyo bwo gukurikirana ibyihutirwa.
4. Uburyo bwo gukurikirana laboratoire.
Potentiometric titre (GB / T14671-93, ubwiza bwamazi)
Uburyo bwo kwinjiza atome (GB / T15506-95, ubwiza bw'amazi)
Igitabo Cyuburyo bwa Atomic Absorption Uburyo bwo Gusesengura Ubushakashatsi no Gusuzuma Imyanda Ikomeye, Byahinduwe n'Ubushinwa Ikigo gishinzwe gukurikirana ibidukikije n'ibidukikije.
5. Ibidukikije.
| Icyahoze ari Leta Zunze Ubumwe z'Abasoviyeti | Umubare ntarengwa wemewe wibintu byangiza mukirere cyamahugurwa | 0.5mg / m3 |

6. Uburyo bwihutirwa bwo kuvura no kujugunya.
i. gutabara byihutirwa kumeneka
Gutandukanya akarere kanduye kandi ukabuza kwinjira. Gabanya isoko yumuriro. Abashinzwe ubutabazi barasabwa kwambara masike yuzuye ivumbi hamwe n imyenda irinda umuriro. Ntukajye uhura neza na suka. Isuka rito: Irinde kuzamura ivumbi hanyuma ukusanyirize mu bikoresho byumye, bisukuye, bitwikiriye amasuka meza. Kwimura kubitunganya. Isuka rinini: Gupfukirana urupapuro rwa plastike cyangwa canvas kugirango ugabanye gutandukana. Koresha ibikoresho bidacana kugirango wimure kandi usubiremo.
ii. ingamba zo gukingira
Kurinda ubuhumekero: Mubisanzwe nta burinzi budasanzwe busabwa, ariko birasabwa ko kwiyitirira-kwiyungurura umukungugu wuzuye umukungugu wambara mubihe bidasanzwe.
Kurinda amaso: Kwambara ibirahuri byumutekano.
Kurinda umubiri: Kwambara imyenda ikingira imiti.
Kurinda intoki: Kwambara uturindantoki.
Ibindi: Kunywa itabi birabujijwe rwose kurubuga rwakazi. Witondere isuku yawe.
iii. ingamba zambere zubutabazi
Guhuza uruhu: Kuraho imyenda yanduye kandi koza uruhu neza ukoresheje isabune n'amazi.
IJISHO RY'AMASO: Zamura amaso yawe hanyuma usukemo amazi atemba cyangwa saline. Shakisha ubuvuzi.
INHALATION: Kura ahantu vuba vuba uhumeke neza. Komeza inzira ifunguye. Niba guhumeka bigoye, tanga ogisijeni. Niba guhumeka bihagaze, tanga guhumeka neza. Shakisha ubuvuzi.
Kwinjiza: Kunywa amazi menshi ashyushye, gutera kuruka, gusya gastrica hamwe na sodium sulfate ya 2% -5%, hanyuma ugatera impiswi. Shakisha ubuvuzi.
Uburyo bwo kuzimya umuriro: amazi, ifuro, dioxyde de carbone, hydrocarbone ya halogene (nka 1211 yo kuzimya) nubundi kuzimya umuriro. Ifu yumye ya grafite cyangwa izindi fu yumye (nkumucanga wumye) igomba gukoreshwa kugirango uzimye umuriro.
