Aerosol nke abụọ
A secondary organic aerosol (SOA) bụ molekụl a na-emepụta site na oxidation n'ime ọtụtụ ọgbọ nke nne na nna organic molecule.[1] N'adịghị ka aerosols ndị bụ isi, nkè a na-ewepụta kpọmkwem site na biosphere, a na-emepụta aerosols nké abụọ site na homogeneous nucleation site na oxidation nkè gas-phase organic compounds, ma ọ bụ site na condensation na ụmụ irighiri ihe ndị dịbu adị. Ụdị gas-phase ndị a na-eme ka nrụgide ikuku dị elu, nke pụtara na ha na-agbanwe agbanwe ma kwụsie ike na gas-phases. Mgbè oxidation, mmụba polarity, ma si otú a belata volatility, nke molecules na-ebute mbelata nke nrụgide ikuku. Mgbè oxidation zuru oke, nrụgide ikuku dị ala nke na gas-phase compound nkewa n'ime solid-phase, na-emepụta ihe nké abụọ (nke abụọ nke aerosol organic).
SOAs na-anọchite ányá ọnụ ọgụgụ dị ukwuu nke aerosols dị na troposphere.[1]
Echiche na-ezighi ezi bụ na aerosol na-ezo aka na akụkụ siri ike nké oghere ahụ, ébé n'eziokwu, site na nkọwa, ọ bụ njikọta nke gas- na solid-phases nke mejupụtara aerosol.
