We know certain chemicals cause problems in the workplace. The issues now are: Where do they occur in the workplace? How can we best evaluate them? What are the procedures for dealing with them safely? Many books simply define the problem and tell you that you need a program. Air Sampling and Industrial Hygiene gives you a guide to air sampling protocols from start to finish. The book presents sampling technology updated with today's tools - such as microcircuitry and remote sensing. The authors emphasize an interdisciplinary approach to understanding how air monitoring can adequately report current environmental conditions associated with outdoor media, indoor remediation efforts, proximal equipment, interior line monitoring, and the interrelationship of ventilation parameters. In addition to providing the how-tos of sampling, this guide covers the basics of chemical risk assessment, biological assessment, engineering evaluation of mechanical system design criteria, and chemical or process engineering hazard assessments. It presents the information using text, text outlines, graphics, and pictures - including cross sections of instrumentation and side bars to elaborate on complex concepts. Faulty readings caused by poor sampling techniques can be very costly. This book provides the how-tos for making design engineering and on-site decisions as to instrumentation selection and scheduled usage. Air Sampling and Industrial Hygiene Engineering will allow you to complete the sampling process systematically and correctly from initial suspicions to the use of obtained results.

There is hardly any technical library in the world in which the volumes of the Chemical Formulary (Volumes 1-34) do not occupy a prominent place. Chemists both experienced and beginner, continually refer to them. It does not duplicate any of the formulas included in previous volumes, but lists a wide array of modern and salable products from all branches of the chemical industries. An excellent reference for formulation problems. -CONTENTS - I. Introduction - II. Beverages and Foods - III. Coatings - IV. Cosmetics - V. Drug Products - VI. Detergents and Sanitizers - VII. Elastomers and Plastics - VIII. Metals - IX. Polishes - X. Textile Specialties - XI. Miscellaneous - Appendix - Index - PREFACE - Chemistry, as taught in our schools and colleges, concerns chiefly synthesis, analysis, and engineering-and properly so. It is part of the right foundation for the education of the chemist. Many a chemist entering an Industry soon finds that most of the products manufactured by his concern are not synthetic or definite complex compounds, but are mixtures, blends, or highly complex compounds of which he knows little or nothing. The literature in this field, if any, may be meager, scattered, or obsolete. Even chemists with years of experience In one or more Industries spend considerable time and effort in acquainting themselves with any new field which they may enter. Consulting chemists similarly have to solve problems brought to them from industries foreign to them. There was a definite need for an up-to-date compilation of formulae for chemical compounding and treatment. Since the fields to be covered are many and varied, an editorial board of chemists and engineers engaged in many industries was formed. Many publications, laboratories, manufacturing firms, and Individuals have been consulted to obtain the latest and best information. It is felt that the formulas given in this volume will save chemists and allied workers much time and effort. Manufacturers and sellers of chemicals will find, In these formulae, new uses for their products. Non-chemical executives, professional men, and Interested laymen will make through this volume a "speaking acquaintance" with products which they may be using, trying or selling. It often happens that two Individuals using the same Ingredients in the same formula get different results. This may be due to slight deviations in the raw materials or unfamiliarity with the intricacies of a new technique. Accordingly, repeated experiments may be necessary to get the best results. Although many of the formulas given are being used commercially, many have been taken from the literature and may be subject to various errors and omissions. This should be taken into consideration. Wherever possible, it is advisable to consult with other chemists or technical workers regarding commercial production.
