Agate is a stone that created due to natural processes from the deposition of fossils and formation minerals combine become an agate. In essence, agate contains elements contained therein. The content these can be used distinguish type Several methods are detect elemental agate, including X-Ray Fluorescence Diffraction methods. this study, will tested using LIBS method. method alternative effec...

OBJECTIVES Agate workers are chronically exposed to silica dust generated from agate grinding, which makes them susceptible to silicosis. In the absence of diagnosis at an early stage, the workers continue to be exposed to silica dust until the development of silicosis. The present study was undertaken to investigate total lactate dehydrogenase (LDH) activity in blood samples of silica-exposed ...

It is well known that an exposure to crystalline silica gives rise to silicosis and silico-tuberculosis (TB). In the agate industry of Khambhat (Gujarat) not only workers but also people staying in the vicinity of the agate-grinding facilities are exposed to crystalline silica. To reduce their dust exposure, dust control devices were developed. There are approximately 500 grinding machines loca...

Agate attracts the attention of gem mineralogists because its variable colors. The color agate is closely related to naming and classification, so it necessary study mineral origin agate. In this paper, mineralogical characteristics red, yellow green Moqi agates from Inner Mongolia were systematically studied by means Fourier transform infrared spectrometer, Raman X-ray powder diffractometer, e...

background: agate is a hard silica stone with bands of various colors, which is used in jewelry. the agate grinding workers are exposed to silica dust. objective: to determine the prevalence of respiratory diseases in agate grinding workers and the associated factors. methods: in this cross-sectional study, 170 agate grinding workers from mashhad, northeastern iran, were examined. medical and o...
