Background and aims: Bio aerosols in the workplace of health-care workers is one of the hazardous agents that needs more research. .This study investigated the feasibility application of the Iranian natural zeolites (INZ) for purification of air contaminated with seudomonas aerognisa. Methods: In this study INZ was prepared in laboratory conditions. The INZ crushed and pulverized using grin...
the removal of fine particles less than 2.5 μm in diameter generated from industrial plantsrepresents a serious challenge in air pollution abatement. these particles can penetrate deeply into the lungs and are difficult to remove by cyclones, electrostatic precipitators, and other conventional separation devices. in this paper, the influence of acoustic waves on removing aerosol particles from ...
Particle size distribution is a major factor in the health and climate effects of ambient aerosols, it shows large variation depending on prevailing atmospheric emission sources. In this work, particle number distributions air were investigated at suburban detached housing area northern Helsinki, Finland, during half-year period from winter to summer 2020. The measurements conducted with scanni...
Organic chemistry in aerosol water has recently been recognized as a potentially important source of secondary organic aerosol (SOA) material. This SOA material may be surface-active, therefore potentially affecting aerosol heterogeneous activity, ice nucleation, and CCN activity. Aqueous aerosol chemistry has also been shown to be a potential source of light-absorbing products ("brown carbon")...
The “Software Package for Aerosol Size Distribution” is a novel graphical user interface application software used for the study of atmospheric aerosol size distribution from various aerosol models (Continental clean, Continental average, Continental polluted, Urban, Desert, Maritime clean, Maritime polluted, Maritime tropical, Arctic, Antarctic) and/or with different aerosol components (insolu...
Understanding aerosol effects on global climate requires knowing the global distribution of tropospheric aerosols. By accounting for aerosol sources, transports, and removal processes, chemical transport models simulate the global aerosol distribution using archived meteorological fields. We develop an algorithm for retrieving global aerosol sources from satellite observations of aerosol distri...
