英文摘要: Abstract(#br)This study investigated the chemical profiles of PM 2.5 from open burning of electronic waste (E-waste), household garbage, wheat residue, and outdoor barbeque in a combustion chamber. Carbonaceous fractions, including polycyclic aromatic hydrocarbons (PAHs), and water-soluble ions and elements in PM 2.5 were quantified. A PM 2.5 exposure study was performed to detect PM 2.5 -induced bioreactivities in vascular smooth muscle cells (VSMCs). Among all fractions, organic carbon (OC) exhibited the highest mass contribution to PM 2.5 —ranging from 39.9% ± 0.82% to 53.1% ± 8.76%. Proportions of total water-soluble ions and total elements both followed the sequence E-waste > wheat straw > outdoor barbeque > household garbage. Because of the high burning temperature, outdoor barbeque...
