Investigation of formaldehyde removal from synthetic contaminated air by using human hair
Background: Human hair can be used as an inexpensive and accessible adsorbent to remove a variety of pollutants from air. Although several studies have been done on removal of formaldehyde from wastewater by human hair, to date no study has investigated using hair to remove formaldehyde from air. Therefore, the aim of this study was to remove formaldehyde from synthetic contaminated a...
متن کاملPolonium-210 activity in human hair samples and factors affecting its accumulation
Background: Due to the presence of radioactive minerals such as monazite, the beach sand of the west coast of Kanyakumari exhibits high natural background radiation. Hair is a good indicator of radionuclides in the human body. An attempt is taken to measure the 210Po activity in human hair samples and the factors affecting it. Material and Methods: 210Po activity was analysed in 47 ind...

متن کاملStructural investigations of human hairs by spectrally resolved ellipsometry.
Human hair is a biological layered system composed of two major layers, the cortex and the cuticle. We show spectrally resolved ellipsometry measurements of the ellipsometric parameters Psi and Delta of single human hairs. The spectra reflect the layered nature of hair and the optical anisotropy of the hair's structure. In addition, measurements on strands of human hair show a high reproducibil...
