Geological keeb kwm: lub voj voog ntawm phosphorus nyob rau hauv cov xwm

Lub cycling ntawm qhov teeb meem - ib yam ntawm cov tseem ceeb tshaj plaws kev cai ntawm qhov. Cov dej nyob rau hauv lub reservoirs qhuav nyob rau hauv tus ntawm lub hnub, lub nce mus rau hauv cov huab cua, thiab ces nyob rau hauv daim ntawv ntawm nag rov qab los rau dej thiab pas dej. Nroj tsuag loj hlob tawm ntawm cov av, nws ua obsolete thiab muab mus rau hauv humus nyob rau hauv tib lub av. Cov tib yam tshwm sim muaj ntau yam minerals.

Phosphorus thiab nws cov khoom

Cycling ntawm phosphorus nyob rau hauv qhov nyob rau hauv lawv tus kheej txoj kev heev nthuav. Nyob rau hauv ib puag ncig ntuj, qhov no caij yog thoob plaws nyob rau hauv loj txaus ntau. Cov kev faib ua feem ntawm nws txheem nyob rau hauv sab hauv ntawm lub ntiaj teb yog hais txog 0,12%. Los ntawm cov neeg kawm ntawv ntawm kis ntawm cov tshuaj nyob rau hauv lub cortex nws yog lub thib kaum peb qhov chaw. Loj deposits ntawm no substance tsis muaj nyob. Phosphorus nyob rau hauv cov xwm Nws yog hais txog mus rau lub thiaj li hu ua tawg ntsiab.

Lwm feature ntawm phosphorus - nws cov high degree ntawm oxidation. Vim hais tias nyob rau hauv nws cov ntshiab daim ntawv nyob rau hauv cov xwm, nws tsis tshwm sim. Tab sis nws yog ib feem 120 ntawm cov zaub mov thiab lawv lub tebchaw, lub tseem ceeb tshaj plaws uas yog phosphorites thiab apatites. Ntxiv mus, zaum tau ntev pom tias qhov tshwm sim ntawm biogenic ntsiab nyob rau hauv lub nqaij ntawm cov nroj tsuag, txiv hmab txiv ntoo thiab noob. Tej yam no hu ua phospholipids. Phosphorus voj voog nyob rau hauv qhov yog cai nyob yug thiab kev tuag ntawm cov nroj tsuag.

Ib tug tseem ceeb kev faib ua feem ntawm phosphorus atoms pom nyob rau hauv cov ntaub so ntswg uas muaj sia nyob, protein tebchaw, ATP, thiab DNA molecules. Biologists hu nws lub "caij ntawm lub neej". Lwm lub npe - "lub caij ntawm xav," hais tias yog mus phosphorus activates hlwb muaj nuj nqi, tu nws, spurs puas siab puas ntsws kev ua si ...

Cycling ntawm phosphorus nyob rau hauv cov xwm muaj feem xyuam rau txhua theem ntawm lub ecosystem, tsis suav xwb cov cua. Qhov no tshwm sim raws li nram no: nyob rau hauv lub chav kawm ntawm cov kev ua ntawm kab mob, av apatite acid maj yaig deposits. phosphorous ntsiab yog ib feem ntawm lub biochemical kev voj voog. Qhov phosphates nyob rau hauv cov av pub rau cov nroj tsuag. Phosphorus tebchaw tso nyob rau hauv lub txiv hmab txiv ntoo thiab noob.

Ntawm cov nroj tsuag uas muaj kev koom siv nyob rau hauv khoom noj khoom haus cov tsiaj thiab tib neeg nyob rau hauv thawj qhov chaw yog legumes. Lawv pab raws li cov khoom noj rau cov tib neeg thiab herbivores, thiab phosphorus yog ib lub tsev ntaub rau cov pob txha ntawm cov tsiaj thiab tib neeg skeletons. Qhov no luag hauj lwm yog ua calcium ntsev ntawm phosphoric acid. Yog hais tias lub cev muaj cov tsis muaj ntawm lawv, lub cev pib txom nyem los ntawm tag nrho cov hom ntawm pathologies rau no hauv paus: pob txha fragility, etc. Ib tug loj npaum li cas ntawm phosphorus muaj nyob rau hauv cov hniav ... Phosphorus-muaj tshuaj raug tshuaj kho mob nrog digestive dab, phua thiab tsim nyob rau hauv lub tshiab organic compound. Nrog faeces phosphates dua mus rau hauv cov av.

Lub phosphorus voj voog nyob rau hauv lub qhov ntawm ib tug neeg koom tes, nws tsim nyog ua. Qhov no lub caij yog dav siv nyob rau hauv qhov siv thiab ua qhov yuam kev. Muaj ntau ntau ntau yam ntawm stainless steel coated nrog ib tug nyias txheej ntawm ntsev nyob rau hauv thiaj li yuav ua rau nws paub ntau tshaj resistant rau weathering. Zoo ib yam li ua yog raug cov khoom ntawm zinc hlau, txhuas thiab lwm yam hlau. Ntawm phosphorus tebchaw ua tshuaj.

Lub geological voj voog ntawm tshuaj muaj thiab chiv, uas yog ntxiv rau cov av nyob rau hauv raws li cov kev xav tau ntawm ua liaj ua teb. Rau lawv cov khoom yog tseem natural phosphates.

Nyob rau hauv ib co chaw ntawm terrestrial hom muaj pom nyob rau hauv loj qhov ntau txuam nrog ntawm organic phosphates. Piv txwv li, guano - noog quav, nyob rau ntawm ib tug high kev faib ua feem ntawm phosphorus. Nws yog pom nyob rau hauv qhov chaw ntawm loj zes noog - .. Nyob rau hauv lub Pacific Islands tuaj, Peru, etc. Deposits ntawm ib tug neeg phosphate tebchaw nyob rau hauv terrestrial pob zeb yuav qhia rau koj txog tag nrho cov xaiv ntawm geological qeeg, ua nyob rau hauv cov tsiaj tuag en masse. Nyob rau lub ntiaj teb no extinction ntawm marine kab hais tias biolitnaya hypothesis tsim phosphate.
