Hauv ntau lub nroog hauv ntiaj teb, muaj qhov teeb meem ib puag ncig zoo li kev lag luam paug. Qhov chaw ntawm cov pa phem yog cov chaw tsim khoom, chaw tsim hluav taws xob, chaw tsim hluav taws xob thiab dej siv hluav taws xob, chav tsev boiler thiab kev hloov pauv chaw, chaw nres tsheb thiab chaw faib roj, chaw rau khoom rau cia thiab ua khoom lag luam.
Hom kev ua kuab paug rau
Txhua qhov chaw tsim khoom tsim kom muaj cov pa phem los ntawm ntau txoj kev thiab cov tshuaj yeeb dej caw. Qhov feem ntau ntawm cov pa phem ntau dua yog cov hauv qab no:
- Tshuaj lom neeg. Txaus ntshai rau ib puag ncig, tib neeg thiab tsiaj lub neej. Cov pa phem yog cov tshuaj lom neeg thiab cov tshuaj lom neeg xws li formaldehyde thiab chlorine, sulfur dioxide thiab phenols, hydrogen sulfide thiab carbon monoxide
- Kev ua qias tuaj ntawm hydrosphere thiab lithosphere. Cov chaw tsim khoom nqa tawm cov dej khib nyiab pov tseg, roj thiab roj siv roj nchuav, khib nyiab, lom thiab lom cov kua tshwm sim
- Kev lom. Cov kab mob thiab kab mob nkag mus rau cov kab biosphere, uas kis rau saum huab cua, dej, av, ua rau muaj kab mob rau tib neeg thiab lwm yam muaj sia. Qhov phom sij tshaj plaws yog cov ua rau cov neeg mob lom lom voos, mob tetanus, mob plab, raws plab, thiab kab mob fungal
- Nrov nrov. Kev hnov lub suab thiab tshee tshee ua rau cov kab mob ntawm cov khoom hauv nruab siab ntawm txoj kev hnov thiab lub paj hlwb
- Thermal. Cov dej sov ua kom muaj kev hloov pauv hloov cov tsoomfwv thiab qhov kub thiab txias ntawm ib puag ncig hauv thaj chaw dej, qee hom plankton tuag tawm, thiab lwm tus neeg nyob hauv lawv cov niche
- Kev tawg. Tshwj xeeb cov pa phem uas tshwm sim los ntawm kev sib tsoo ntawm cov chaw tsim hluav taws xob nuclear, thaum lub sij hawm tso tawm cov pa paug thiab thaum lub sij hawm tsim tawm ntawm cov riam phom nuclear
- Kev siv tshuab paug qias neeg. Muaj tshwm sim vim kev ua haujlwm ntawm cov xaim hluav taws xob, radars, chaw nres tsheb hauv TV, thiab lwm yam khoom siv uas tsim cov xov tooj cua
Muaj Kev Ua qias tuaj txo quag kom tsawg
Ua ntej tshaj plaws, txo qib theem ntawm kev ua qias tuaj nyob ntawm lub lag luam lawv tus kheej. Txhawm rau qhov no tshwm sim, kev tswj hwm ntawm cov chaw tsim khoom, chaw nres tsheb thiab lwm qhov chaw yuav tsum lawv tus kheej tswj cov txheej txheem ua haujlwm, them nyiaj tshwj xeeb rau kev tu thiab pov tseg ntawm cov pov tseg. Ntxiv rau, nws yog qhov yuav tsum tau siv thev naus laus zis qis thiab kev tsim kho ntawm ecological, uas yuav txo tau qib ntawm kev ua qias tuaj thiab txo qhov cuam tshuam tsawg tshaj rau cov ib puag ncig ntuj. Thib ob, kev ua qias tuaj yuav txo tau yog nyob ntawm qhov muaj peev xwm, kev saib xyuas thiab kev tshaj lij ntawm cov neeg ua haujlwm lawv tus kheej. Yog tias lawv ua lawv txoj haujlwm zoo hauv kev lag luam, nws yuav txo tau kev pheej hmoo ntawm kev lag luam muaj kuab paug ntawm cov nroog.
