Preliminary Assessment: Identification of Chinese Drywall and Exposure to Particulate Matter and Metals during Cutting and Installation of Drywall
Drywall, a popular building material made of gypsum based plaster sandwiched between two thick sheets of paper is used for building interior walls, is speedier alternative to traditional plaster, decreasing time and labor for construction. Importance of drywall increased with the demand for drywall …
