Optical and microphysical properties of the columnar Aerosol burden over the Eastern Mediterranean: Discrimination of Aerosol types
Tutsak, Ersin; Koçak, Mustafa (2020-05-15)
Optical and microphysical properties, for example, refractive index, single scattering albedo (SSA) and asymmetry factor were attained from AERONET ground based sun sky radiometer situated at rural coastal Erdemli in the E...
A new exposure route to trace elements in indoor particulate matter.
Broomandi, P; Amouei, Torkmahalleh; Akturk, M; Ngagine, Sh; Gorjinezhad, S; Ozturk, F; Koçak, Mustafa; Kim, J (2019-12-30)
Concentrations and emission rates of sixteen trace elements in emitted PM during heating soybean oil using three types of pans, including Teflon, granitium, and cast-iron, were investigated. Statistically significant decre...
