The objective of this study is to assess the quartz content and physical characteristics of four selected rock dusts, consisting of limestone or marble in both treated (such as treatment with stearic acid or stearates) and untreated forms. Four selected rock dusts (an untreated and treated limestone and an untreated and treated marble) were aerosolized in an aerosol chamber. Respirable size-selective sampling was conducted along with particle size-segregated sampling using a Micro-Orifice Uniform Deposit Impactor. Fourier Transform Infrared spectroscopy and scanning electron microscopy with energy-dispersive X-ray (SEM-EDX) analyses were used to determine quartz mass and particle morphology, respectively. Quartz percentage in the respirable dust fraction of untreated and treated forms of...

This effort is necessary because the DM-450 filters are no longer commercially available. For example, the MSHA Pittsburgh laboratory alone analyses annually approximately 15,000 samples according to the MSHA P-7 method that requires DM-450 filters. There is an impending shortage of DM-450 filters. Membrane filters suitable for on-filter analysis should have high infrared (IR) transmittance in the spectral region 600-1000 cm(-1). Nylon (47 mm, 0.45 µm pore size), PP (47 mm, 0.45 µm pore size) and PVC (47 mm, 5 µm...

Eco-friendliness, durability, and resistance to staining, make artificial stone attractive to consumers. Health concerns have arisen during manufacturing of artificial stone due to increased incidence of silicosis after relatively short exposure. Three artificial stone samples (A, B, and C) and one natural granite sample were subjected to cutting and grinding in a controlled environment. Gravimetric analysis, X-Ray diffraction, and scanning electron microscopy with energy dispersive spectroscopy were employed to determine crystalline silica concentrations and particle morphology of bulk and respirable particles. Silica content of bulk dust from artificial samples A and B was 91%, sample C was <10%, while granite was 31%. Silica percent in the respirable fraction for samples A and B was 53% and 54%, respectively, while sample C was <5% and granite was 8%....

This is a healing book. Life itself wrote this book. All I can offer you is my reality, my simple truth. The book burst out of my journal with its own identity after twenty years of weekly confessions. What happened under the streets of Bucharest will sink into your mind and take you back into the dark communism times.

This book is well laid out in 14 sections. It draws the reader in, which certainly assists with the increased retention of the amount of material that has to be covered. The questions are well introduced with a short narrative before introducing the pertinent equations and solution to the over 450 examples of essential questions. The book serves as a formidable preparation for the CHMM exam and a good review of basic principles, a reference for many of the day-to-day technical issues confronting the practicing worker’s safety, and a guide for raising awareness of potential problems for which alert action is required. The authors bring a breadth of experience and insight into the issues handled in the text. They bring context to the basic principles to be highlighted by the examples of the questions and their solutions. CHMM Exam - Essential Practice should be a must-have text for everyone in the field. Michael McCawley, Ph.D., West Virginia University.
