Health great

Susan s is one of nine households of chemically sensitive people who have clustered in the desert near Snowflake, seeking respite from the pollutants of more populated areas and creating their own safe community. One family, their health greatly improved, recently moved on to Montana to resume a more mainstream lifestyle. Susan and one other El neighbor woman are members of the Unitarian-Universalist Church, despite the fact they cannot attend traditional services. The two women meet in Susan s home or talk on the phone.

The state of knowledge in the early 1990s of the effects of fat on health lacks clarity and general agreement. There is great support for the thesis that fully saturated fats are associated with problems of atherosclerosis and arterial fatty deposit, but there is evidence that stearates, which are saturates, are only poorly utilized in human digestion. Another body of work has estabUshed a connection between unsaturated fatty acids and a better state of arterial health and lowered fat body attachment to the arterial wall (23) contrary evidence exists that highly unsaturated fats polymerize more readily and thus contribute to arterial plaque formation. 

There is great interest in developing soft lens materids that have high oxygen permeabdity and good wettabdity. Such lenses will provide patients with good comfort, high deposit resistance, and superior corneal health, particularly for extended wear appHcations. 

Health and Safety Factors As a class, surfactants and detergent products are among the most widely used chemical compositions. Almost everyone is exposed to these products on a daily basis ia situatioas that range from ingestion of food-grade emulsifiers to intimate coatact of skin and eyes with personal-care and laundry products. Safety is therefore a matter of great importance (132,133). Ranges of surfactant LD q values are shown ia Table 2. 

Optimization of nourishment for the population of Ukraine is a key factor in improving the health of the nation. Therapeutic and preventive significance of the fortificated food products depends on keeping to the scientifically substantiated regulated levels of fortification. Taking into consideration the above-mentioned, a sanitary and chemical control of the quality of the fortificated products seems to be of great importance. 

Smoke and ash abatement in Great Britain was considered to be a health agency responsibility and was so confirmed by the first Public Health Act of 1848 and the later ones of 1866 and 1875. Air pollution from the emerging chemical industry was considered a separate matter and was made the responsibility of the Alkali Inspectorate created by the Alkali Act of 1863. 

The effect of accumulation in various systems depends greatly on the quantity of pollutants involved. Many pollutants can be detected at concentrations lower than those necessary to affect human health. For pollutants which are eliminated slowly, individuals can be monitored over long periods of time to detect trends in body burden the results of these analyses can then be related to total pollutant exposure. Following are two examples of air pollutants that contribute to the total body burden for lead and carbon monoxide. 

In Great Britain the COSHH Regulations cover virtually all substances hazardous to health. (Excluded are asbestos, lead, materials dangerous solely due to their radioactive, explosive, or flammable properties, or solely because of high or low temperatures or pressures, or where risk... 

In Great Britain the Health and Safety (First Aid) Regulations 1981 require an employer to provide sueh equipment and faeilities as are adequate and appropriate in the eireumstanees to enable first aid to be rendered to his employees if they are injured, or beeome ill, at work. An Approved Code of Praetiee gives more speeifie details on the number of first-aid personnel and their training, and the type of equipment. 

The reasons for such strict regulation of air pollution are obvious protecting human health and the environment. Potential air pollutants are not only toxic in many cases, but they can travel over great distances, thereby impacting areas remote from the sources of emissions. There are two environments that are of concern, once chemicals are emitted to the surroundings ... 

A difficulty that should not be overlooked is that airborne particulates are rarely homogeneous. They vary greatly in size and shape, and their chemical composition is determined by factors specific to the source and location of the emissions. The combined effects and interactions of various substances mixed with particulates have not yet been established (except for sulfur dioxide), but they are believed to be significant, especially where long-term exposure occurs. Measurement techniques and their reliability may vary across regions and countries, and so may other factors, such as diet, lifestyle, and physical fitness, that influence the human health effects of exposure to particulates. 

The threshold for toxic injury is not the same for everyone because sensitivity varies greatly among individuals. Most chemicals in consumer products remain untested for health effects, such as cancer, reproductive problems, and the impacts of long-term, low level exposure. How these substances affect women, children, and people with existing conditions is also little studied. Once a person s defenses have been broken down and he or she has become hypersensitive, a wide variety of common chemical exposures can trigger a reaction. Just what products and other chemicals which cause problems varies greatly among affected individuals.
