Raws li tau cog lus tseg, ntawm no yog ib zaj dab neeg txog daj phosphorus thiab yuav ua li cas nws hlawv gloriously ze Lvov nyob rau hauv Ukraine kuj tsis ntev los no.
Yog lawm, kuv paub - Google muab ntau cov ntaub ntawv hais txog qhov xwm txheej no. Hmoov tsis zoo, feem ntau ntawm qhov nws muab tawm tsis muaj tseeb, lossis, raws li cov neeg tim khawv hais, tsis muaj tseeb.
Cia peb kawm!
Zoo, thaum pib - tsis muaj leej twg nyiam cov khoom, tab sis los ntawm txoj kev nws tseem ceeb heev!
Raws li kev tho txawv Wikipedia, phosphorus yog ib qho ntawm cov ntsiab lus ntawm lub ntiaj teb pob zeb: nws cov ntsiab lus yog 0,08-0,09% ntawm nws qhov loj. Nws tsis pom nyob rau hauv lub xeev dawb vim nws cov tshuaj lom neeg ua haujlwm siab. Nws tsim txog 190 cov zaub mov, qhov tseem ceeb tshaj plaws yog apatite Ca5 (PO4) 3 (F, Cl, OH), phosphorite Ca3 (PO4) 2 thiab lwm yam. Phosphorus yog ib feem ntawm cov tshuaj lom neeg tseem ceeb tshaj plaws - phospholipids. Muaj nyob rau hauv cov ntaub so ntswg tsiaj, yog ib feem ntawm cov proteins thiab lwm yam tseem ceeb organic tebchaw (ATP, DNA), yog ib feem ntawm lub neej. Nco ntsoov qhov no, % username%, thiab peb mam li mus.
Phosphorus nyob rau hauv nws daim ntawv ntshiab yog dawb, liab, dub thiab nws yog xim hlau. Qhov no yog hu ua kev hloov kho allotropic - kev sib deev tsis muaj zog yog qhov zoo heev hauv lawv, vim tias los ntawm kev kov lawv tuaj yeem paub qhov txawv ntawm pob zeb diamond los ntawm graphite - thiab cov no kuj yog kev hloov kho allotropic, tsuas yog rau cov pa roj carbon. Feem ntau, phosphorus yog tib yam.
Tus hero ntawm peb zaj dab neeg - daj phosphorus - yog tiag tiag unrefined dawb. Feem ntau, "unrefined" txhais tau hais tias ib qho kev sib xyaw ntawm cov phosphorus liab, thiab tsis yog qee qhov txawv teb chaws txaus ntshai.
Daj phosphorus (txawm li cas los xij, zoo li dawb) yog ntuj txiag teb tsaus tiag tiag: muaj kuab lom heev (qhov siab tshaj plaws concentration txwv nyob rau hauv atmospheric cua yog 0,0005 mg / mΒ³), ββββflammable crystalline tshuaj los ntawm lub teeb daj mus rau tsaus xim av xim. Lub ntiajteb txawj nqus 1,83 g / cmΒ³, melts ntawm +43,1 Β° C, boils ntawm +280 Β° C. Nws tsis yaj hauv dej, yooj yim oxidizes hauv huab cua thiab ignites spontaneously. Nws kub hnyiab nrog lub teeb ntsuab ci ntsa iab nrog kev tso tawm ntawm cov pa luam yeeb dawb - me me ntawm tetraphosphorus decaoxide P4O10. Qhov no tho txawv Wikipedia dua, tab sis thov, %username% - nco ntsoov cov ntaub ntawv no thiab.
Tam sim no peb yuav nkag siab.
Zoo, ua ntej, txawm tias muaj phosphorus toxicity, nws yog ib qho nyuaj heev rau tshuaj lom rau lawv vim yooj yim heev: nws ignites spontaneously nyob rau hauv huab cua. ceev heev. Thiab nws kub hnyiab, raws li twb tau hais, nrog ib tug xiav kaj ntsuab nplaim. Hauv kev xyaum, nws zoo li qhov no: koj muab ib daim rau ntawm lub rooj - thiab nws maj mam pib haus luam yeeb li ntawd. Ces sai dua. Ces ntxiv. Thiab ces nws flashes thiab hlawv. Lub sijhawm flash nyob ntawm qhov loj ntawm daim: qhov me, qhov nrawm dua. Tias yog vim li cas nws yog ib qho nyuaj rau kuv xav txog tej yam zoo hmoov av ntawm daj phosphorus nyob rau hauv cov huab cua - nws yuav tsuas ntes hluav taws.
Txawm li cas los xij, tej zaum koj yuav tsis pom zoo, lawv sau ntawm no: koob tshuaj daj phosphorus rau ib tug neeg yog 0,05-0,15 grams, nws dissolves zoo nyob rau hauv lub cev kua thiab sai sai absorbed thaum noj (los ntawm txoj kev, liab phosphorus yog insoluble thiab yog li ntawd kuj tsawg. - tshuaj lom). Mob hnyav tshwm sim thaum daj phosphorus vapors nqus tau thiab / lossis thaum lawv nkag mus rau hauv plab hnyuv. Tshuaj lom yog tus cwj pwm los ntawm qhov mob hauv plab, ntuav, zoo nkauj ci ntsa iab hauv qhov tsaus nti ntuav uas tawm cov ntxhiab tsw ntawm qej, thiab raws plab. Lwm cov tsos mob ntawm mob daj phosphorus lom yog lub plawv tsis ua hauj lwm.
Tom qab nyeem qhov no, rau qee qhov laj thawj kuv nco qab txog kev lom phosphine (cov tsos mob zoo sib xws) thiab xav nyuaj - tab sis tsis yog hais txog qhov muaj cov phosphorus vapor, tab sis hais txog qhov txaus ntawm ib tus neeg uas pom ib qho tsis paub txog kev haus luam yeeb, glowing nyob rau hauv qhov tsaus ntuj - thiab tam sim ntawd noj. Zoo, qhov ntawd yog nws.
Los ntawm txoj kev, kom tau txais ib qho kev daws ntawm phosphorus hauv dej ntawm 3 mg / l - thiab qhov no yog cov tshuaj saturated, nws tsis yaj ntxiv lawm - koj yuav tsum co ib daim ntawm phosphorus hauv dej rau ib lub lis piam. Zoo, Kuv tsis tuaj nrog qhov no, GOST 32459-2013 hais tias yog li ntawd - thiab qhov no tsis yog txhua yam hauv Internet rau koj!
Feem ntau, nyob rau hauv kuv lub tswv yim, toxicity ntawm phosphorus yog heev exaggerated. Tab sis nws muaj lwm yam nuances. Txog lawv - hauv qab no.
Phosphorus hlawv, raws li cov kws tshaj lij uas ua haujlwm nrog nws nyiam hais tias, raws li txoj cai gimlet: uas yog, ib qho hluav taws kub tau noj rau hauv qhov chaw uas nws hlawv. Rau lub rooj. Hauv hlau. Hauv khau raj. Hauv tes. Yog vim li cas yooj yim: cov khoom ntawm combustion - phosphorus oxide - yog ib qho tseem ceeb acidic oxide, uas tam sim ntawd nqus dej, tsim phosphoric acid. Phosphoric acid, txawm tias tsis qab zib li sulfuric lossis hydrofluoric acid, nyiam noj tsis tsawg - thiab yog li ntawd corrodes txhua yam. Los ntawm txoj kev, nws yog qee zaum ntxiv rau cov kua rau ntxuav chav dej. Kev sib xyaw ua ke zoo ntawm qhov kub thiab txias (txog 1300 Β° C) thiab cov kua qaub kub thiab muab qhov ntxiv rau koj lub rooj, thiab yog tias koj tsis muaj hmoo, koj lub cev. Thiab yog, %username% mob heev.
Kuv twb tau hais ntau zaus thiab tseem yuav hais ntxiv tias tsis muaj tus yeeb ncuab loj dua ntawm tus txiv neej dua li nws tus kheej: tau kawg, cov khoom ntawm daj phosphorus tsis tau mus unnoticed - thiab cov neeg zoo tuaj nrog lub tswv yim ntawm kev ntxiv rau incendiary. mos txwv, vim nws yooj yim heev thaum ib yam dab tsi dheev ntes hluav taws saum huab cua!
Nws zoo nkaus li zoo heev - koj tuaj yeem qhuas
Tab sis cov neeg tom qab xws li kev tawm tsam tsis zoo nkauj heev - yog li koj zoo dua tsis saib
Txij li thaum tag nrho cov no yog ntxim nyiam heev, kev txhim kho, kev sim, kev thauj mus los, kev lag luam, kev siv thiab pov tseg ntawm phosphorus munitions raug coj mus rau hauv tus account ntau qhov kev pom zoo thoob ntiaj teb thiab kev cog lus, suav nrog:
- St. Petersburg tshaj tawm "Rau qhov kev tshem tawm ntawm kev siv cov mos txwv tawg thiab incendiary" xyoo 1868.
- Cov Txheej Txheem Ntxiv ntawm 1977 rau Geneva Convention for the Protection of Victims of War, 1949, txwv tsis pub siv cov phosphorus munitions dawb yog tias cov pej xeem muaj kev phom sij. Tebchaws Meskas thiab Ixayees tsis tau kos npe rau lawv, los ntawm txoj kev.
- Raws li Txoj Cai Thib Peb rau xyoo 1980 UN Convention on Certain Weapons, riam phom incendiary yuav tsum tsis txhob siv tawm tsam cov pej xeem, thiab, ntxiv rau, lawv yuav tsum tsis txhob siv tawm tsam cov hom phiaj ua tub rog uas nyob hauv thaj tsam ntawm cov neeg pej xeem.
Feem ntau, muaj ntau cov ntaub ntawv, tab sis lawv muaj cov xwm txheej ze rau chav dej, vim tias cov mos txwv no tau siv txhua lub sijhawm - Palestine thiab Donbass yuav lees paub.
Txij li thaum phosphorus reacts nrog dej tsuas yog nyob rau ntawm qhov kub siab tshaj 500 degrees Celsius, cov dej ntau yog siv los tua phosphorus (kom txo qhov kub ntawm qhov hluav taws kub thiab hloov phosphorus mus rau ib tug khoom lub xeev) los yog ib tug daws ntawm tooj liab sulfate (tooj liab sulfate), tom qab. quenching, phosphorus yog poured ntub xuab zeb. Txhawm rau tiv thaiv kev sib tsoo, cov phosphorus daj yog khaws cia thiab thauj mus rau hauv ib txheej dej (calcium chloride tov, kom meej, tab sis dej kuj yuav tawm). Qhov no tseem ceeb heev!
Leej twg tsim phosphorus? Thiab ntawm no, % username%, ib tug neeg yuav muaj kev txaus siab: tus neeg muag khoom tseem ceeb ntawm phosphorus, zaub mov phosphoric acid, sodium hexaphosphate thiab tripolyphosphate zoo siab Kazakhstan!
Nyob rau hauv qhov tseeb, txij li thaum lub sij hawm ntawm lub USSR, nyob rau hauv lub koob meej lub nroog ntawm Dzhambul (yog, lub npe ntawm tib Dzhambul Dzhabaev), lub Kazphosphate tuam txhab uas muag tau tsim. Tom qab ntawd Dzhambul tau hloov npe hu ua Taraz - zoo, cia peb tsis tham txog qhov ua tau zoo, Kazakhs paub zoo dua - tab sis lub lag luam tseem nyob. Lub xub ntiag ntawm cov khoom siv raw thiab lub peev xwm, nrog rau cov nqi qis heev ntawm kev ua haujlwm (thiab muaj, qhov tseeb, tsis muaj lwm qhov chaw ua haujlwm hauv Taraz / Dzhambul) tau txiav txim siab tias daj phosphorus yog tsim ntawm no.
Thaum kuv nyob ntawm lub tuam txhab no - nws zoo nyob ntawd! South Kazakhstan, 300 km rau Uzbekistan - sov! Noog hu nkauj! Txhua yam yog ntsuab! Roob ntawm lub qab ntug! Kev zoo nkauj!
Los ntawm txoj kev, Kazphosphate nroj tsuag tsis cuam tshuam qhov idyll nyob rau hauv txhua txoj kev: tag nrho cov nyob rau hauv greenery, paj, nyob rau hauv txoj kab nqes ntawm ib tug me me roob.
Nws yeej zoo nyob ntawd
Qhov laj thawj rau kev zoo nkauj yog qhov yooj yim - cov khoom siv raw, cov khoom siv thiab cov khoom pov tseg yog cov khoom siv phosphorus, uas yog cov tshuaj chiv. Qhov no yog qhov uas nws loj hlob thiab blooms.
Los ntawm txoj kev, cov tub ceev xwm siab tshaj plaws ntawm cov nroj tsuag tsis nyiam dandelions heev. Tsis muaj leej twg paub vim li cas. Thiab yog li ntawd, ua ntej mus ntsib cov tub ceev xwm siab tshaj plaws, cov neeg ua haujlwm npaj ib lub subbotnik rau cov nroj tsuag tawm dandelions. Zoo, yuav ua li cas nws yog - mus tua nrog dandelions - txhua leej txhua tus paub los ntawm lub dacha / zaub vaj, nyob rau hauv lub moj khaum ntawm phosphoric lawlessness, qhov no yog kiag li pointless: txaus rau ib hnub, siab tshaj plaws - ob. Tab sis kev coj noj coj ua yog qhov nws yog.
Kuv txaus siab tshwj xeeb los ntawm kev ua haujlwm ntawm chav kuaj ntawm lub tuam txhab. Muaj ib co nerds loj heev tawm muaj. Thiab rau koj kom nkag siab, % username%, ob peb qhov tseeb.
Hauv cov phosphorus daj, nws yog ib qho tseem ceeb heev rau kev tswj cov impurities - tshwj xeeb tshaj yog arsenic, antimony, selenium, npib tsib xee, tooj liab, zinc, txhuas, cadmium, chromium, mercury, lead, hlau. Txhawm rau tswj txhua qhov no, phosphorus yuav tsum tau yaj, thiab tib lub sijhawm, txhua yam uas tswj tau yuav tsum tsis txhob ya mus.
Qhov teeb meem thib ib: yuav ua li cas ntsuas ib yam dab tsi uas ntes hluav taws hauv huab cua? Lawv ua li no: lawv rauj ib lub ingot ntawm phosphorus nyob rau hauv ib txheej ntawm dej, tshem tawm cov loj pieces - me me flare sai heev - thiab hloov mus rau ib khob dej. Tom qab ntawd lawv hnyav dua lwm khob dej, noj phosphorus los ntawm thawj zaug, so nrog cawv, tos kom txog thaum nws qhuav - thiab muab pov rau hauv ib khob dej hnyav. Qhov loj ntawm phosphorus yog txiav txim los ntawm qhov sib txawv ntawm qhov hnyav.
Txij li thaum nws tuaj yeem ntes hluav taws - muaj kev daws ntawm tooj liab sulfate nyob ze - yog tias nws ntes hluav taws, ces lawv muab pov rau hauv nws.
Tom qab ntawd cov phosphorus yog yaj. Nws dissolves nyob rau hauv nitric acid saturated nrog bromine vapor - ib qho khoom qab zib heev thiab qab ntxiag. Kuv pom zoo hauv kev lag luam. Nws yog ib qho tsim nyog yuav tsum pov phosphorus rau hauv qhov sib tov, tom qab ntawd ua kom sov me ntsis, thiab thaum cov tshuaj tiv thaiv pib, hloov mus rau ib lub trough nrog dej txias, vim hais tias cov cua sov yog loj heev. Thiab do, do, do - yog tias koj tsis cuam tshuam, ces daim yuav tsuas dhia tawm ntawm lub bubbling kua zaub - cov txiaj ntsig yuav tsis raug! Lawv cuam tshuam nrog tes, muaj ob lub mittens ntawm nws: roj hmab los ntawm cov kua qaub - thiab hnov ββββntawm qhov kub thiab txias (tsuas yog roj hmab yog yaj, tab sis tsuas yog hnov ββ- tsis txuag los ntawm tee ntawm cov kua qaub. Txawm li cas los xij, yog tias phosphorus nkag mus, ob qho tib si yuav tsis txuag. .
Fascinating spectacle ntawm dissolution ntawm daj phosphorus
Nyob rau tib lub sijhawm, nitrogen oxides thiab bromine ya - qhov no yog ib qho kev ceeb toom. Cov ntxhais ntshai ntawm cov tails liab thiab cov phosphorus, uas tuaj yeem hnav khaub ncaws lossis mitten. Poisoning "pairs" lossis "kev daws teeb meem" ntawm phosphorus tsis nco qab.
Los ntawm txoj kev, cov nyiaj hli ntawm cov ntxhais uas ua qhov no tsis siab tshaj $ 200 (thiab cov lus teb yog yooj yim: tsis muaj lwm qhov chaw ua haujlwm hauv Taraz, kuv twb tau hais qhov no lawm). Yog li lub sij hawm tom ntej, % username%, thaum koj quaj txog cov nyiaj ua haujlwm qis thiab kev ua haujlwm tsis zoo, nco ntsoov Kazphosphate!
Zoo, tam sim no hais tias cov kev paub yooj yim tau sau tseg, cia peb txav mus rau qhov xwm txheej tiag tiag hauv Lviv.
Txij li thaum phosphorus yog nyob rau hauv kev thov nyob rau hauv Teb chaws Europe, Kazphosphate nquag xa tawm cov khoom los ntawm Czech koom tes. Nws caij nyob rau hauv lub tank ntim nrog dej, thiab nws yog tseeb hais tias los ntawm rail.
Hnub Monday, Lub Xya hli ntuj 16, 2007 ntawm 16:55 nyob rau hauv lub Busk koog tsev kawm ntawv ntawm lub Lviv cheeb tsam ntawm Ukraine nyob rau theem Krasne-Ozhidiv, 15 tso tsheb hlau luam nrog daj phosphorus ntawm freight tsheb ciav hlau No. 2005 derailed thiab overturned. Tag nrho muaj 58 wagons. Cov tso tsheb hlau luam ua raws los ntawm Kazakh chaw nres tsheb Asa (Taraz, Kazakhstan) mus rau Oklesa chaw nres tsheb (Public of Poland). Cov dej xau ntawm phosphorus los ntawm ib lub tank provoked spontaneous combustion ntawm rau lwm lub tank.
Nws ntsia epic
Thiab ces - ib tug sib tov ntawm ceeb, inflated los ntawm cov xov xwm, tsis muaj kev paub nrog daj phosphorus thiab ua tiav ignorance ntawm chemistry.
Thaum lub sijhawm tua hluav taws, huab cua ntawm cov khoom siv hluav taws xob tau tsim nrog thaj tsam ntawm thaj tsam li 90 square kilometers. Thaj chaw no suav nrog 14 qhov chaw nyob ntawm Bussky koog tsev kawm ntawv, qhov twg 11 tus neeg nyob, nrog rau cov cheeb tsam sib cais ntawm Radekhiv thiab Brodiv cheeb tsam ntawm cheeb tsam. Lub Tsev Haujlwm Saib Xyuas Kev Nyab Xeeb ntawm Ukraine tau muab cov neeg nyob hauv cov zos nyob ze kom khiav tawm thiab xa lawv txog kaum lub tsheb npav, tab sis ntau tus neeg tsis kam tawm hauv lawv lub tsev. Cov tub ceev xwm Lviv tau lees paub tias tsis muaj leej twg yuav raug yuam kom khiav tawm, txawm hais tias lawv tau ceeb toom txog qhov tsis muaj kev cia siab ntawm qhov tshwm sim ntawm qhov xwm txheej. Nyob rau hauv tag nrho, kwv yees li 6 tus neeg nyob hauv ib ntus tau hloov chaw nyob ib ntus los ntawm 800 qhov chaw nyob hauv cheeb tsam Bus hmo ntuj.
Txog hnub Tuesday, muaj 20 tus neeg raug mob (6 tus kws tshaj lij ntawm Ministry of Emergency Services, 2 tus neeg sawv cev ntawm Ministry of Internal Affairs, 2 tus neeg ua haujlwm hauv kev tsheb ciav hlau thiab 10 tus neeg los ntawm cov pej xeem hauv zos), ntawm 13 tus neeg tau pw hauv tsev kho mob hnyav thiab nruab nrab. ntawm cov tub rog kho mob chaw kho mob ntawm Western Operational Command hauv Lviv. Xya lub tsev kho mob yog cov neeg ua haujlwm ntawm Ministry of Emergency Situation, ob tug yog cov neeg ua haujlwm ntawm Lub Xeev cov neeg soj ntsuam tsheb, plaub yog cov neeg nyob hauv zos.
Nyob rau tib lub sijhawm, qhov phem tshaj plaws thiab wildest howl tau sawv hauv xov xwm. Qee cov pearls:
- ...
Nyeem tag nrho cov no ua rau kuv tu siab. Vim hais tias nws qhia meej ignorance ntawm chemistry nyob rau hauv lub loj. Thiab tseem - nws yooj yim npaum li cas los tswj cov neeg tsis muaj kev kawm (los ntawm txoj kev, % username%, thiab koj paub tias cov tswv qhev hauv Tebchaws Meskas tau ntseeg ruaj khov tias cov qhev yuav tsum tsis paub ntawv - kom lawv tsis tuaj yeem ua daim ntawv pov thawj so haujlwm, lwm yam ntaub ntawv, sib txuam nrog lwm cov kev sib hais haum, koom tes tawm tsam thiab lwm yam - me ntsis tau hloov).
Ntau lossis tsawg dua cov xwm txheej hauv lub sijhawm muaj nyob ntawm no (ua tib zoo - Ukrainian, yog tias koj tsis paub txaj muag - Google Txhais lus):
Dab tsi tuaj yeem nkag siab los ntawm qhov chronology no?
- Tsis muaj leej twg paub dab tsi.
- Txhua leej txhua tus xav tau kev txhawb nqa.
- Cov neeg tua hluav taws / Ministry of Emergency Situation tau ntshai.
- Tub rog thiab.
- Ntawm cov neeg hauv zos muaj kev ntxhov siab.
- Txog thaum cov neeg sawv cev ntawm Kazphosphate tuaj txog thaum Lub Xya Hli 18, tsis muaj leej twg nkag siab tias yuav ua li cas.
- Tsis muaj leej twg xav them dab tsi.
Tom qab kev sib tham nrog qee tus neeg ua haujlwm ntawm Kazphosphate, uas ncaj qha cuam tshuam rau kev tshem tawm cov txiaj ntsig ntawm kev sib tsoo, kuv tuaj yeem hais cov hauv qab no.
Tsis muaj kev tawg / tshwm sim tshwm sim / tawg ntawm phosphorus - nws calmly caij nws tus kheej hauv qab dej. Yog, thiab daj phosphorus tsis tuaj yeem tawg los ntawm nws tus kheej! Tab sis muaj kev puas tsuaj rau txoj kev tsheb ciav hlau, uas ua rau cov tanks derail. Thaum cov tso tsheb hlau luam tsoo, tawg tsim, dej ntws tawm los ntawm nws - zoo, phosphorus ignited yam xyuam xim. Qhov kub thiab cov yam ntxwv ntawm combustion thaum kawg rhuav tshem lub tank.
- Cov pa luam yeeb dawb yog nkag siab - nws yog ib khub ntawm phosphoric acid, tab sis tsis yog phosphorus. Yog tias koj ua pa rau lawv - yog, hnoos hnyav yuav pib thiab feem ntau nws tsis muaj txiaj ntsig tshwj xeeb. Txawm li cas los xij, nws tsis yog tuag taus. Feem ntau ntawm kev raug mob ntawm cov pej xeem hauv zos yog vim qhov tseeb tias tib neeg tau khiav mus sau cov khoom haus luam yeeb nthuav dav hauv cov fwj dej, tab sis lub cordon tsis tau teeb tsa tam sim ntawd - txhua tus ntshai.
- Kev ntshai ntawm cov neeg tua hluav taws uas xav tias "cov khib nyiab no yog hluav taws los ntawm dej!" Vim lub fact tias lub dav hlau muaj zog ntawm cov dej tsoo cov phosphorus rau hauv me me pieces - zoo, lawv ya sib nrug thiab ntes tau hluav taws. Nws yog qhov tsim nyog txawm tias nrog cov kwj tsis muaj zog, lossis nrog ua npuas dej, uas tau ua tiav tom qab.
- Los ntawm txoj kev, thaum txhua yam raug tua thiab tsuas yog cov khoom nyob hauv lub tank, Kazakhs tua nws. Zoo, yuav ua li cas lawv tua nws - lawv khaws nws thiab muab pov rau hauv thoob dej kom ntau dua. Ib tug ntawm lawv yog cov nroj tsuag tus thawj technologist, ib tug avid haus luam yeeb. Yog li - nws muab tawm thiab haus luam yeeb. Hauv qee qhov chaw, txawm tias cov duab ntawm "Vajtswv Kazakh uas haus luam yeeb hauv hluav taws kub heev!" Yog li cas?
- Muaj thiab tsis tuaj yeem muaj kev puas tsuaj ntawm ecological thiab "Chernobyl thib ob" - qhov tseeb, xwm tau txais ib koob tshuaj phosphate chiv.
- Tib neeg uas coj tus cwj pwm zoo, mloog Kazakhs thiab ua qhov yog yog Vladimir Antonets, Thawj Tus Lwm Thawj Coj ntawm Ministry of Emergency. Tej zaum vim Colonel General nrog ib pawg khoom plig.
Tom qab nws tau pom tseeb tias qhov kev xav tsis ua haujlwm: tsis muaj kev ua phem tawm tsam, tsis muaj kev hem thawj ntawm kev puas tsuaj ntawm ecological - kuj, tsis muaj leej twg tuag thiab tsis muaj nyiaj yuav muab - lawv sai sai poob paj rau kev puas tsuaj. Qhov laj thawj ntawm kev sib tsoo yog:
- Kev tsis txaus ntawm cov lem ntawm txoj kev tsheb ciav hlau no.
- Ua txhaum txoj cai kev nyab xeeb los ntawm cov neeg ua haujlwm ntawm cov neeg ua haujlwm hauv lub tsheb.
- Kev tsis saib xyuas (tsis quav ntsej cov lus qhia ntawm kev ntsuas kub rau kev thauj khoom tshwj xeeb tshaj yog txaus ntshai).
- Kev tsis txaus ntseeg ntawm lub tank.
Qhov tseeb, qhov tseeb tshaj plaws ntawm cov no yog thawj. Tus so tau ntxiv kom tsis txhob them cov Kazakhs rau qhov poob ntawm cov khoom thauj. Zoo, nws zoo li kev pov hwm them rau nws.
Yog li ntawd txhua leej txhua tus nyob ntawm lawv tus kheej.
Kev ncaj ncees,% username%: kawm chemistry. Nws nyob txhua qhov chaw. Nws yuav pab kom koj nyob, thiab ciaj sia, thiab nkag siab ib yam dab tsi rau koj tus kheej.
Thiab thaum kawg ...
Tsis yog txhua yam tshuaj muaj teeb meem. Yog tsis muaj hydrogen thiab oxygen, piv txwv li, dej, lub ntsiab ntawm npias, yuav tsis ua tau.
- Dave Barry, yeej tsis yog kws tshuaj
