Book excerpt: Excerpt from Laboratory Notes: Sanitary Chemistry and Water Analysis The application of chemistry to problems of public health or gen eral sanitation is of comparatively recent date, and its importance can hardly be overrated from the present standpoint. Of the relation between health and the condition of air, water, and food materials as regards the action of the lower forms of life. Soil and food are the hotbeds in which these lower forms of life are propagated and from which they are carried by water and air as well as by actual contact. Sanitary biology is concerned with the organisms themselves; sanitary chemistry with the detection and interpretation of the changes which they cause in the materials in which they grow, and with the production of certain substances inimical to health. In these notes are illustrated the more common changes which are now known to be caused by these organisms. In order to interpret correctly the results obtained, it is necessary to know the normal com position oi the materials in question. To determine this often involves analytical processes not strictly included under the head of sanitary tests, namely, the determination of total solids, ash, etc., and certain changes of sanitary significance not due to the lower forms of life, such as the vitiation of air by the burning of lights or the breathing of human beings. Sanitary chemistry may also properly include the examination of articles of food for the presence of adulterants or poisons. It is evident that any classification of topics is only temporary and tentative in the present state of knowledge. Water analysis and air analysis are each treated in a separate section. In the' former the products of bacterial action are to be most carefully studied and accurately determined, in order that the deductions from the results may be of value. Soil analysis has been fully described in works on agricultural chemistry (see page and is therefore omitted. Food analysis is treated on the broad lines above indicated. A few typical substances only will be considered, and the methods of examination given will be such as to elucidate the scientific aspect rather than technical detail of the subject. Both on account of its importance as a food stuff and on account of its availability for the tests, milk has been chosen as a type of animal food. This classincludes meats and meat products, meat tablets, peptones, and other prepared animal foods. The same methods of examination may be applied to the analysis of fertilizers.

Book excerpt: Whether you are a new employee or seasoned professional you need easy access to the latest test methods, updated quality control procedures, and calculations at your fingertips. You need to perform analyses quickly and easily and troubleshoot problems as they arise. You need a resource that is not only informative, but also practical and easy to use. Drinking Water Chemistry: A Laboratory Manual fills this need. The book gives you a thorough overview of the most basic, and therefore important, laboratory topics such as: Laboratory Safety - dos and don'ts based on real experience Sampling - preservation techniques, online sampling, and record keeping Laboratory Instruments - practical use ranges, principles of operation, calibration, conditioning, useful life and replacement, common quality control issues Chemical Use - reagents, standards, indicators, purpose and use, chemical quality and properties, avoidance of contamination, molecular weight calculations Quality Control - replicate analyses, spiked, split, and reference samples, percent recovery of standard, standard deviation, control charts, and everyday quality control measures Weights and Concentrations - care and analytical balances, mathematical conversions among concentration units, dilutions and concentration changes The remaining chapters cover test analysis including: reason for the test, type of sample taken, treatment plant control significance, expected range of results, appropriate quality control procedures, apparatus used, reagents, including function, concentration and instructions for preparation, procedural steps, calculations and notes on possible problems, and references. This is a working manual, meant to be kept by your side in the lab, not on the shelf in an office or library. You can bend it, you can lay it flat, you can take it anywhere you do your job. Useful and practical Drinking Water Chemistry: A Laboratory Manual provides the information you need to perform tests, understand the results, apply them to the determination of water quality before and after treatment, and troubleshoot any problems.

Book excerpt: In addition to detailed instructions for sampling and immediate analysis, the book provides a concise presentation of both the theoretical background and data evaluation. The analytical methods thus presented can just as easily be applied using simple equipment as well as in the modern laboratory. The book is a bench-top laboratory manual and as such can be used for instruction in laboratory staff training programs. It treats the analysis of organic and inorganic compounds while also dealing with microbiological problems associated with the guidelines for waste, surface and ground water, as well as drinking water quality.

THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing...
