As I read it, I thought some of you might just appreciate some quotes. Please realise that we now have 50 years of experience, and that it's not a scientific paper. It is reporting on a meeting of the National Association of Insecticide and Disinfectant Manufacturers. Enjoy.... NADIM Holds 31st Annual Meeting Harry W.Stenerson, Industrial Chemical and Engineering News v.22 p.2179-2180 (December 25 1944) " Late in 1943 the Army was so anxious to obtain the powerful new insecticide for lice extermination that it flew overseas to a fighting front the first 500 pounds made in a pilot plant here. National production has now readed a monthly rate of 2,000,000 pounds, and insecticide manufacturers are eagerly seeking the means of marketing DDT to civilian consumers in formulations that are nontoxic, safe to use, and effective. .... Three of the major addresses' were devoted to the wartime insecticidal wonder. The toxicology of DDT was discussed by Paul A Neal, senior surgeon and chief of the Industrial Hygiene Laboratory, US Public Health Service, Bethesda. Md. ...... household and industrial insecticides containing DDT were the subject of a paper read by George W.Fiero, chief of the Pharmaceutical, Insecticide, and Cosmetic Unit, Office of Civilian Requirements, Washington. ... Dr Neal rendered a detailed report on experimental work with regard to the toxic effects of DDT on man and animals, the subject of greatest concern at this time to both manufacturer and consumer. In spite of its inherent toxicity , the use of DDT in a 1 to 5 % solution in 10% cyclohexanone with 89-85% aerosol should offer no serious health hazards he stated, when used under conditions as required for its use as an insecticide. ... The use of DDT in concentrations up to 10% in inert powders for dusting clothes ( in lice extermination ) appears to offer no serious hazards because of the relative insolubility of DDT and the large particle size of the dust. Therefore it did not reach the alveolar spaces. A large proportion of the dust is retained in the uppermost sections of the respiratory tract and the remainder is swallowed. The objective of the the investigation was the appraisal of health standards connected with the use of DDT as aerosol, mist, spray and dusting powder...In further tests, two human subjects were exposed to a dispersion of DDT in air prepared by dispersing every 15 minutes 10.4 grams of an aerosol containing 5% DDT, 10% cyclohexane, and 85% Freon in a sealed chamber of 14,750-liter capacity, for one hour daily, on six consecutive days. This test failed to show any subjective or objective manifestations referable to DDT. .... DDT production has skyrocketed from 60,000 pounds, in January 1994 to a current rate of approximately 2,000,000 pounds, Dr Fiero of the CCR told the meeting. The Armed Forces are using DDT rather extensively in malarial sections; hence, he thought, no cutbacks could be expected on V-E day. Entire islands in the war zone are being sprayed with DDT from airplanes. With the exception of small quantities for experimental work, all of the current production is being allocated to the Armed Forces. Fiero stated that preliminary research indicates that DDT, in addition to its effectiveness against body lice, should prove very valuable as a toxicant for household and industrial insecticides. It is apparently effective against roaches, fleas, bedbugs, mosquitoes, ticks, chiggers, ants and carpet beetles. Referring to the contention that DDT is fatal to beneficial insects, the speaker felt that this should not deter its use in nonagricultural insecticides unless it is found to be toxic to humans or pets.

Extractions: Land is central to Aboriginal people. It is the basis of all cultural, economic, social and political activity and many people living on Aboriginal lands, especially in the north-west and west of the State, spend considerable time in ritual business and other cultural and social activities. In South Australia Aboriginal people hold title to more than 20% of the land area. The Aboriginal Lands Trust Act 1966 was the first in Australia to ensure that the titles to the existing Aboriginal Reserves were held in trust on behalf of all Aboriginal people in South Australia. The Aboriginal Lands Trust (ALT) also holds freehold title to Aboriginal Lands not held under other titles, and currently controls an area of 5,500 square kilometres. The Pitjantjatjara Land Rights Act 1981 ensures that the Anangu Pitjantjatjara have control over some 102,500 square kilometres in the far north-west of the State. There are eight major communities on the Lands and some 160 homelands or satellite communities incorporated under the Aboriginal and Torres Strait Islander Commission (ATSIC). These homelands have enabled many people to return to their country to escape the pressures of the larger communities, establish a degree of independence and separate identity, and to gain access to resources.

Extractions: Introduction If men could learn from history, what lessons it might teach us! Samuel Taylor Coleridge 1836 What is the value of history to ecology? More specifically, what can historical, time-series data tell us that is relevant to current land management? We addressed this question by looking at how humans have influenced the Palouse Prairie of west-central Idaho. Our objectives were to (1) develop a history of European-American settlement and biological diversity in the Palouse bioregion, (2) use this history to understand how human activities have altered land cover and ecological integrity of the bioregion, and (3) assess the utility of information of differing scales and time periods. We believe that understanding the biophysical changes that have occurred in this region will provide a useful starting point for establishing research hypotheses, conservation goals, and ecological restoration efforts.

Extractions: LEPTOSPIROSIS SUMMARY Leptospirosis is a contagious disease of animals and humans caused by infection with the spirochete Leptospira . Laboratory diagnostic procedures for leptospirosis fall into two groups. The first group consists of tests for the demonstration of leptospires or their genetic material in animal tissues or body fluids. The second contains the tests for antibody detection. The selection of tests to be carried out depends on the purpose for which a diagnosis is to be made and the resources available.

Facts About Fats The Oiling Of America, Part 1 when the Department of agriculture had begun Kritchevskys rabbit trials were actuallya repeat everything from energy provision to prostaglandin production. http://www.westonaprice.org/know_your_fats/oiling.html
Extractions: by Mary Enig , PhD, and Sally Fallon In 1954 a young researcher from Russia named David Kritchevsky published a paper describing the effects of feeding cholesterol to rabbits. Cholesterol added to vegetarian rabbit chow caused the formation of atheromasplaques that block arteries and contribute to heart disease. Cholesterol is a heavy weight moleculean alcohol or a sterolfound only in animal foods such as meat, fish, cheese, eggs and butter. In the same year, according to the American Oil Chemists Society, Kritchevsky published a paper describing the beneficial effects of polyunsaturated fatty acids for lowering cholesterol levels. Polyunsaturated fatty acids are the kind of fats found in large amounts in highly liquid vegetable oils made from corn, soybeans, safflower seeds and sunflower seeds. (Monounsaturated fatty acids are found in large amounts in olive oil, palm oil and lard; saturated fatty acids are found in large amounts in fats and oils that are solid at room temperature, such as butter, tallows and coconut oil.) Scientists of the period were grappling with a new threat to public healtha steep rise in heart disease. While turn-of-the-century mortality statistics are unreliable, they consistently indicate that heart disease caused no more than ten percent of all deaths, considerably less than infectious diseases such as pneumonia and tuberculosis. By 1950, coronary heart disease, or CHD, was the leading source of mortality in the United States, causing more than 30% of all deaths. The greatest increase came under the rubric of myocardial infarction (MI)a massive blood clot leading to obstruction of a coronary artery and consequent death to the heart muscle. MI was almost nonexistent in 1910 and caused no more than three thousand deaths per year in 1930. By 1960, there were at least 500,000 MI deaths per year in the US. What life-style changes had caused this increase?

Extractions: Introduction AlternativeA - No Action Alternative B - Proposed Action Alternative C ... Back to FEIS Table of Contents Cumulative effects are defined as the impact on the environment which results from the incremental impact of the action when added to other past, present and reasonably foreseeable future actions regardless of what agency (Federal or non-federal) or person undertakes such other actions. (40 CFR 1508.7). Cumulative effects must be evaluated along with direct and indirect effects of each alternative. Generally, cumulative effects are considered on a larger scale than the direct and indirect effects. They describe a larger picture across a longer time frame. When analyzing cumulative effects, different temporal and geographic scales are used than for direct and indirect effects. These scales of analysis extend only to where effects can actually be measured (EPA 1997). Cumulative effects analysis involves assumptions and uncertainties. Cumulative effects analysis provides the opportunity to evaluate future Grassland management options in the context of other developments in the analysis area.
