Txhua yam khoom uas tuaj yeem ua rau huab cua tsis zoo yog cov pa phem.
Muaj tej yam ntuj tso (xws li hluav taws kub hav zoov, hluav taws kub tawg, thiab lwm yam) thiab cov khoom tsim los ntawm tib neeg (xws li kev lag luam emissions, hluav taws xob hluav taws xob hauv tsev, hluav taws xob tsheb, thiab lwm yam).Cov tom kawg yog qhov tseem ceeb, tshwj xeeb tshaj yog cov uas tshwm sim los ntawm kev tsim khoom thiab kev thauj mus los.
Ntuj qhov chaw:
Ntuj qhov chaw ntawm cov pa phem xws li:
volcanic eruption: Emission ntawm H2S, CO2, CO, HF, SO2 thiab volcanic tshauv thiab lwm yam teeb meem.
Hluav taws kub hav zoov: Emission ntawm CO, CO2, SO2, NO2, HC, thiab lwm yam.
Ntuj hmoov av: cua thiab xuab zeb, av plua plav, thiab lwm yam.
Hav zoov tso tawm: feem ntau yog terpene hydrocarbons.
Hiav txwv yoj droplet cov teeb meem feem ntau: sulfate thiab sulfite
Cov peev txheej ntuj no tsis muaj kev zam.

Cov pa phem uas tib neeg tsim los ntawm lub tsheb tso tsheb thiab cov cua kub hauv nruab nrab.Tab sis cov teeb meem tsis zoo kuj raug tso tawm rau hauv huab cua hauv lwm txoj hauv kev los yog tsim hauv huab cua los ntawm kev cuam tshuam nrog lwm yam tshuaj.Qhov chaw ntawm cov khoom muaj xws li cov xim, ntxuav cov kua thiab cov kuab tshuaj.
Lub nroog huab cua muaj kuab paug nrog rau lub tsheb tso tsheb thiab cov roj hluav taws xob hauv nruab nrab cua sov, ua liaj ua teb slurry muab cov pa phem thiab.Yog li ntawd yog vim li cas cov lus qhia tshiab thiaj li nyuaj rau tsoomfwv.Txawm koj nyob qhov twg, lub nroog lossis lub tebchaws, nws nyuaj rau kev khiav tawm ntawm huab cua.
Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb (WHO) tau ceeb toom tias huab cua muaj kuab lom ntau dua li qhov kev xav yav dhau los, vim tias nws txo qis qhov siab tshaj plaws ntawm cov pa phem tseem ceeb xws li nitrogen dioxide.Lub koom haum WHO kwv yees tias kwv yees li ntawm 7 lab tus tib neeg tuag ntxov ntxov txhua xyoo los ntawm cov kab mob ua pa phem.Cov teb chaws tau nyiaj tsawg thiab nruab nrab raug kev txom nyem ntau tshaj plaws, vim lawv tso siab rau fossil fuels rau kev txhim kho kev lag luam.Lub koom haum WHO lees paub huab cua muaj kuab paug ua paug ib puag ncig tsis zoo, thiab lawv tau hais kom nws 194 cov tswvcuab hauv lub xeev kom txo cov pa tawm thiab muaj qee yam kev hloov pauv huab cua ua ntej COP26.
Rau cov neeg uas muaj teeb meem plawv thiab ntsws, nws tsis yog xov xwm hais tias cov tshuaj lom thiab cov pa phem ua rau tib neeg nyob rau theem qis dua li qhov kev xav yav dhau los.Qhov phem tshaj plaws, cov khoom me me tuaj yeem ua pa rau hauv lub ntsws, thiab tib neeg tsis tuaj yeem tiv thaiv nws.
Cov txheej txheem tshiab tau txiav txim siab ib nrab qhov siab tshaj plaws rau kev nthuav tawm cov khoom me me hu ua PM2.5s.Cov no yog tsim los ntawm kev kub hnyiab hauv hluav taws xob tsim hluav taws xob, cua sov hauv tsev thiab lub cav tsheb.
"Yuav luag 80% ntawm cov neeg tuag muaj feem xyuam rau PM2.5 tuaj yeem zam tau hauv ntiaj teb yog tias cov pa phem tam sim no tau txo qis rau cov uas tau hais hauv cov lus qhia tshiab, nws tseem tab tom txiav cov kev txwv tsis pub lwm tus ntawm micro hais, hu ua PM10. , los ntawm 25%.WHO hais.
"Kev txhim kho huab cua zoo tuaj yeem txhim kho kev hloov pauv huab cua kom txo qis kev siv zog, thaum txo qis emissions yuav ua rau huab cua zoo," WHO hais.
