As people spend a greater portion of their time indoors, the likelihood of exposure to biohazards in indoor air is
increasing. This study developed a system to disinfect indoor bioaerosols while prot...
North American isoprene influence on intercontinental ozone pollution
North American isoprene intercontinental ozone pollution
2011/2/25
Changing land-use and climate may alter emissions of biogenic isoprene, a key ozone (O3) precursor. Isoprene is also a precursor to peroxy acetyl nitrate (PAN) and thus affects partitioning among oxid...
