Piv txwv ntawm a cov pa phem thib ob suav nrog ozone, uas yog tsim thaum hydrocarbons (HC) thiab nitrogen oxides (NOx) ua ke nyob rau hauv lub xub ntiag ntawm tshav ntuj; NO2, uas yog tsim los ua NO sib txuas nrog cov pa oxygen hauv cua ; thiab kua qaub nag, uas yog tsim thaum sulfur dioxide lossis nitrogen oxides cuam tshuam nrog dej.

Cov lus nug tseem yog, leej twg ntawm cov hauv qab no yog cov pa phem thib ob?

Secondary pollutants tsis tawm ncaj qha. Lawv tsim los ntawm kev sib xyaw ua ke ntawm cov thawj cov pa phem nrog rau qee qhov sib xyaw. Piv txwv ntawm cov pa phem thib ob yog Ozone, Formaldehyde, PAN (peroxy acetyl nitrate) thiab Smog thiab lwm yam.

Ib yam li ntawd, piv txwv ntawm cov pa phem hauv thawj thiab theem nrab yog dab tsi? Piv txwv ntawm thawj cov pa phem suav nrog sulfur dioxide (SO2), carbon monoxide (CO), nitrogen oxides (NOX), thiab teeb meem me me (PM). Piv txwv ntawm cov pa phem thib ob suav nrog photochemical oxidants (ozone, nitrogen dioxide, sulfur trioxide) thiab theem nrab teeb meem.

Ib yam li ntawd, tib neeg nug, dab tsi yog thawj thiab theem nrab huab cua ua pa phem?

A thawj kuab paug yog ib pa phem emitted ncaj qha los ntawm ib qhov chaw. A cov pa phem thib ob tsis yog ncaj qha tso tawm xws li, tab sis daim ntawv thaum lwm cov pa phem ( thawj cov pa phem ) hnov mob hauv cov cua.

Qhov twg hauv qab no yog cov pa phem thawj?

Thawj qhov kuab paug yog huab cua ua pa tawm ncaj qha los ntawm qhov chaw, xws li carbon monoxide (CO), oxides ntawm nitrogen ( NOx , TSIS MUAJ), sulfur oxides (SOx), SO $$ _ 2 $$, cov organic sib txuas hloov pauv (VOCs) thiab cov teeb meem me me (hmoov av, tshauv, ntsev ntsev).
