Kev plua plav hauv pem teb yog qhov khoom uas yuav tsum tau ncaj qha mus kho hauv chav qis. Qhov feem ntau siv los ntxuav cov cuab yeej yog qhov suav cov khoom raws li tus zauv ntawm ≥0.5μm, nyob rau hauv qhov huv si stratosphere (10 km ntawm qhov chaw). Cov zauv muaj li ntawm 20 nplej / L, thiab muaj txog 2,600 nplej / L ntawm lub hiav txwv dej huv. Cov kev sib tw terrestrial sib txawv heev, thiab qhov sib txawv ntawm tib lub sijhawm kuj tseem loj. Lub zog nyob hauv Suav teb tau muab sib faib ua cov "industrial city", "nroog suburbs", "non-industrial areas lossis rural areas", thiab cov ntsiab lus ntawm ≥0,5 μm. Lawv 1 × 10 6 hais / L, 2 × 10 5 hais / L, thiab 3 × 10 5 hais / L, feem.
Cov kab mob atmospheric concentration
Cov pa phem ntawm atmospheric plua plav yog rau cov pa phem ntawm cov khoom ua pauj, thiab cov pa phem ntawm atmospheric kab mob belongs rau cov pa phem ntawm cov neeg nyob. Microorganisms muaj xws li: kab mob, rickettsia, kab mob, fungi, thiab protozoa. Tab sis feem ntau yog hais txog kev ntxuav chav yog cov kab mob thiab cov hu ua fungi. Txawm li cas los xij, cov kab mob tsis tuaj yeem muaj sia nyob, thiab feem ntau ua raws li cov plua tshauv, qhov luaj li cas yog qhov sib npaug. Thaum ib pawg ntawm cov kab mob kis tau los ntawm cov lim, qhov kev pom zoo ntawm cov kab mob yog zoo ib yam li cov txiaj ntsig ntawm cov khoom ntawm ib qho kev loj me me. Qhov loj me me yog qhov sib npaug ntawm cov pejxeem ntawm cov khoom.
Sab hauv paug
Tus nqi ntawm hmoov av nyob rau hauv chav qis neeg muaj peev xwm raug xam tias raug tshem tawm los ntawm lub zos qaug thiab tsis ntws mus rau hauv chav tu chav. Tus nqi ntawm hmoov av thaum lub sij hawm kev thauj mus los ntawm cov khoom thiab cov khoom yog feem ntau me me piv nrog cov nyiaj ntawm hmoov av uas tsim los ntawm tib neeg lub cev. . Vim tias qhov kho kom zoo nkauj kho kom zoo zoo siv cov hlau zoo dua qub, cov hmoov av tau los ntawm qhov chaw ntawm lub tsev kuj tseem tsawg, feem ntau yog siv tsawg tshaj li 10%, thiab hmoov av feem ntau yog los ntawm tib neeg, uas yog li 90%.
P2 kuaj
1. Ua tau raws li cov cai ntawm BSL-2 laboratory construct.
2. Lub qhov rooj sim muaj qhov xauv thiab tuaj yeem kaw tau. Lub qhov rooj ntawm lub tsev kuaj mob yuav tsum muaj qhov rais.
3. Muaj chaw txaus rau cov khoom siv. Kuj tseem muaj chaw cia khoom siv rau hauv qhov chaw ua hauj lwm (lab).
4. Yuav tsum muaj cov ntaub ntawv rau khaws cia khaub ncaws ntawm lub chaw ua haujlwm ntawm chav kuaj.
6. Kev siv lub tshuab hluav taws xob puv high-sterilizer rau txhua lub tsev ntawm lub chaw kuaj kab mob, thiab tshawb xyuas thiab tshawb xyuas raws sij hawm kom ua raws li kev cai.
7. Txuas nrog lub txee rau kev nyab xeeb hauv kev sim.
8, txhawm rau tsom iav qhov chaw, yog tias tsim nyog, yuav tsum muaj cov dej kub ntxhov ceev
9. Xav txog kev kho qhov cua, xws li kev siv lub qhov rais rau cov qhov cua, thiab cov kab tsuag.
10. Muaj lub hwjchim ntawm lub hwjchim thiab kev pom kev kub ceev. Thaum tsim nyog, cov cuab yeej tseem ceeb xws li cov kab tsim kev lag luam, cov khoom xyaw roj ntsha, cov tub yees, thiab lwm yam khoom siv yuav tsum yog siv cov khoom siv hluav taws xob rau khoom.
11. Cov chaw kuaj qhov chaw muaj cov cim uas qhia tau meej nyob rau hauv qhov tsaus ntuj.
BOKA Lub Tsev Kawm Ntawv Phaj Siab yog qhov kev pabcuam ib-ncua, nrog rau kev tshawb fawb ntawm lub tsev ntsuab thiab kev tsim, kev ua txhua yam kev sib tham tswv yim, kev kuaj hauv kev tsim kho vaj tse, kev tsim cov rooj tog khoom tsim, kev ntsuas khoom noj khoom haus, kev kuaj xyuas thiab kev sim. Laboratory qib high-kawg kho kev pabcuam xws li chaw thau tsev, kuaj kev sibtham hauv Mall, kev tshawb nrhiav kev tshawb nrhiav hauv tsev kawm ntawv.
