Pulmonary function parameters and its determinants among cement factory workers in Chhattisgarh: A cross-sectional study.

Background: Cement in one hand is the most used substance for construction all over the world but on the other hand prolonged exposure from cement dust particles along with smoking, long working duration in dusty environments and increasing age impairs pulmonary functions.

Objectives: The study aimed to determine the effect of cement dust on the pulmonary functions of cement factory workers.

Methods: It was a cross-sectional observational study conducted from October 2019 to February 2020 among 360 workers of cement factories of Chhattisgarh state selected by systematic random sampling who were interviewed.

Cool white light emission from Dy activated alkaline alumino silicate phosphors.

A series of single phase white light emitting CaSrAlSiO:Dy phosphors were prepared by traditional high temperature solid state reaction method. Structural characterization was done by X-ray diffraction, field emission scanning electron microscopy and energy dispersive spectroscopy analyses. Optical characterization was performed from photoluminescence and thermoluminescence studies.
