2. Umthelela endaweni ezungezile.
i. izingozi zempilo
Umzila wokuhlasela: ukuhogela, ukungenwa.
Izingozi zempilo: Insimbi ye-barium cishe ayinabo ubuthi. Usawoti we-barium oncibilikayo njenge-barium chloride, i-barium nitrate, njll. (i-barium carbonate ihlangana ne-gastric acid ukuze yakhe i-barium chloride, engamuncwa ngomgudu wokugaya ukudla) ingaba nobuthi obunzima ngemva kokuwagwinya, ibe nezimpawu zokucasuka komgudu wokugaya ukudla, ukukhubazeka kwemisipha okuqhubekayo. , ukubandakanyeka kwe-myocardial, kanye ne-potassium ephansi yegazi. Ukukhubazeka kwemisipha yokuphefumula kanye nokulimala kwe-myocardial kungaholela ekufeni. Ukuhogela uthuli oluyinhlanganisela ye-barium encibilikayo kungabangela ubuthi obuyingozi be-barium, ukusebenza kufana nobuthi bomlomo, kodwa ukusabela komgudu wokugaya ukudla kulula. Ukuchayeka isikhathi eside kuma-barium compounds kungase kubangele ukuqhinqa, ukuphelelwa amandla, ukuphefumula, ukuvuvukala nokuguguleka kolwelwesi lwamafinyila lomlomo, i-rhinitis, i-tachycardia, ukwanda komfutho wegazi nokulahlekelwa izinwele. Ukuhogela isikhathi eside kothuli oluyinhlanganisela ye-barium engancibiliki, njenge-barium sulfate, kungabangela i-barium pneumoconiosis.
ii. ulwazi lwe-toxicological nokuziphatha kwemvelo
Izici eziyingozi: ukusebenza kabusha kwamakhemikhali aphansi, kungavutha ngokuzenzekelayo emoyeni lapho kushiselwa kusimo esincibilikisiwe, kodwa uthuli lungasha ekamelweni lokushisa. Kungabangela ukuvutha nokuqhuma lapho kuvezwe ukushisa, ilangabi noma ukusabela kwamakhemikhali. Lapho ihlangana namanzi noma i-asidi, isabela ngobudlova futhi ikhiphe igesi ye-hydrogen ukuze ibangele ukusha. Lapho uthintana ne-fluorine, i-chlorine, njll., ukusabela kwamakhemikhali anobudlova kuzokwenzeka. Uma kuxhunyanwa ne-asidi noma i-asidi encibilikayo, izodala ukusha nokuqhuma.
Umkhiqizo ovuthayo (ukubola): i-barium oxide.
3. Izindlela zokuqapha izimo eziphuthumayo endaweni.
4. Izindlela zokuqapha ilabhorethri.
I-Potentiometric titration (GB/T14671-93, ikhwalithi yamanzi)
Indlela yokumunca i-athomu (GB/T15506-95, ikhwalithi yamanzi)
I-Atomic Absorption Method Manual Yokuhlaziywa Kokuhlola Nokuhlola Imfucumfucu Eqinile, Ihunyushwe Isiteshi Esijwayelekile Sokuqapha Imvelo Yase-China nezinye.
5. Izindinganiso zemvelo.
| ISoviet Union yangaphambili | Ukugxila okuphezulu okuvunyelwe kwezinto eziyingozi emoyeni waseshabhu | 0.5mg/m3 |
| I-China (GB/T114848-93) | Ikhwalithi yamanzi angaphansi komhlaba (mg/L) | Ikilasi I 0.01; Isigaba II 0.1; Ikilasi III 1.0; Ikilasi IV 4.0; Ikilasi V ngaphezu kwe-4.0 |
| I-China (izoshaywa) | Ukugxila okuphezulu okuvunyelwe kwezinto eziyingozi emithonjeni yamanzi okuphuza | 0.7mg/L |
6. Ukwelashwa okuphuthumayo nezindlela zokulahla.
i. impendulo ephuthumayo ekuchithekeni
Hlukanisa indawo engcolile futhi ubeke umkhawulo ekufinyeleleni. Susa umthombo womlilo. Abasebenzi bezimo eziphuthumayo bayelulekwa ukuthi bagqoke izifihla-buso zothuli ezizibambayo kanye nezingubo zokuvikela umlilo. Ungahlangani ngqo nokuchitheka. Ukuchitheka okuncane: Gwema ukuphakamisa uthuli futhi uqoqe ezitsheni ezomile, ezihlanzekile, ezimboziwe ngefosholo elihlanzekile. Dlulisela ukuze kugaywe kabusha. Ukuchitheka okukhulu: Mboza ngamashidi epulasitiki noma ngeseyili ukuze unciphise ukuhlakazeka. Sebenzisa amathuluzi angeyona inhlansi ukuze udlulise futhi ugaywe kabusha.
ii. izinyathelo zokuzivikela
Isivikelo sokuphefumula: Ngokujwayelekile asikho isivikelo esikhethekile esidingekayo, kodwa kuyanconywa ukuthi imaski yothuli ezizihlungayo igqokwe ezimeni ezikhethekile.
Ukuvikela iso: Gqoka izibuko zokuphepha zamakhemikhali.
Ukuzivikela ngokomzimba: Gqoka izingubo ezivikela amakhemikhali.
Ukuvikela isandla: Gqoka amagilavu erabha.
Okunye:Ukubhema akuvunyelwe ngokuphelele endaweni yomsebenzi. Naka inhlanzeko yomuntu siqu.
iii. izinyathelo zosizo lokuqala
Ukuthinta isikhumba: Susa izingubo ezingcolile bese ugeza isikhumba kahle ngensipho namanzi.
UKUXHUMANA KWAMEHLO: Phakamisa amajwabu amehlo bese uwageza ngamanzi ahambayo noma ngosawoti. Funa usizo lwezokwelapha.
UKUHAMBA: Susa endaweni ngokushesha uye emoyeni omusha. Gcina indlela yokuphefumula ivuliwe. Uma ukuphefumula kunzima, nikeza umoya-mpilo. Uma ukuphefumula kuyeka, nikeza ukuphefumula okwenziwa ngokushesha. Funa usizo lwezokwelapha.
Ukungeniswa: Phuza amanzi amaningi afudumele, bangela ukuhlanza, ukugeza isisu nge-2% -5% ye-sodium sulfate solution, futhi ubangele isifo sohudo. Funa usizo lwezokwelapha.
Izindlela zokucisha umlilo: amanzi, igwebu, isikhutha, ama-halogenated hydrocarbons (njenge-ejenti yokucima umlilo engu-1211) nezinye izicishamlilo. Impushana yegraphite eyomile noma enye impushana eyomile (njengesihlabathi esomile) kufanele isetshenziselwe ukucisha umlilo.
