Collection Efficiencies of Various Airborne Spray Flux Samplers Used in Aerial Application Research
A low air speed, spray dispersion tunnel was constructed and used to evaluate the collection efficiency of passive spray flux collectors. The dispersion tunnel utilizes an air-assisted nozzle to generate a spray cloud with a DV0.5 of 18.5 0.4 μm at air speeds ranging from 0.4–4.0 m/s. A sampling protocol was developed to minimize spray flux and air speed variation effects while providing a chec...
متن کاملHeterogeneous ice nucleation on biological particles: Bacteria and pollen
In the atmosphere the importance of biological ice nuclei is still not well understood. Therefore we investigated the ice nucleation behavior of Snomax, used as a model for bacterial ice nucleation, and birch pollen washing water, used as a model for pollen induced ice nucleation. Thereby we quantified the ice nucleation behavior of the INA protein complexes controlling the ice nucleation abili...
متن کاملNew samplers for collection of sea mud.
To obtain specimens from marine environment, water sampling devices such as Nansen's sampler and sediment sampling device such as a gravity-core sampler are used for geological or ecological examinations in oceanic or aquatic fields. Those samplers are able tocollect a reasonable amount of specimens for the above studies. These devices are all considerably heavy and operated by means of a rope ...
متن کاملCollection efficiency and capacity of three samplers for acidic and basic gases.
This paper compares the collection efficiency and capacity of a coated porous metal disk with those of a silica gel tube and an impinger at the acid or basic aerosol concentration of two times the permissible exposure limitation (Taiwan IOSH, Institute of Occupational Safety and Health), relative humidity of 80 +/- 5%, and temperature of 30 +/- 3 degrees C in the laboratory. Using 5% sodium car...
متن کاملInvestigating of relationship between biological and non-biological airborne particles in the internal section of two educational hospitals in Qazvin city
Background: Hospital-acquired infections, are the most important consequence in exposure to bioaerosols in which affect health of staffs and clients. The present study aimed to investigate the relationship between fungal bioaerosols and particulate matter in two educational hospitals in Qazvin city in 2017. Methods: This descriptive-analytical study, was performed in 12 of two hospitals indoor...
