	FDA/CBER - Thimerosal in Vaccines
		In the following pages, a discussion of preservatives, the use of thimerosal as a preservative, guidelines on exposure to organomercurials (primarily methylmercury), thimerosal toxicity, recent and future FDA actions, and the conclusions of the Institute of Medicine's most recent review of thimerosal in vaccines are presented.
		In some cases, preservatives are added during manufacture to prevent microbial growth; with changes in manufacturing technology, however, the need to add preservatives during the manufacturing process has decreased markedly.
		At concentrations found in vaccines, thimerosal meets the requirements for a preservative as set forth by the United States Pharmacopeia; that is, it kills the specified challenge organisms and is able to prevent the growth of the challenge fungi (U.S. Pharmacopeia 2004).

	Preservative Treated Wood - Publications - BM&WT - UMass Amherst
		The wood preserving industry didn't begin in earnest though, until the late 1800s when America's railroads, faced with a shortage of naturally-durable woods for crossties, started saturating non-durable woods with creosote.
		In addition to creosote, preservatives fall into two classes, oil-borne and water-borne, depending on whether they are carried into wood in an organic liquid or water.
		Preservative penetration and retention with self-treating are minimal.

	Recommendations Regarding the Use of Vaccines That Contain Thimerosal as a Preservative
		Thimerosal is a mercury-containing preservative that has been used as an additive in biologics and vaccines since the 1930s because it prevents bacterial and fungal contamination, particularly in multidose containers.
		One manufacturer reported that the supply of its diphtheria and tetanus toxoids and acellular pertussis (DTaP) vaccine that does not contain thimerosal as a preservative would be sufficient to meet any increased demand during the next year, and three other manufacturers are developing similar DTaP vaccines that could be licensed in the future.
		If the supply of single-antigen hepatitis B vaccines that do not contain thimerosal as a preservative is limited, the priority for its use should be to vaccinate newborn infants (3).

	Pressure Preservative Treatment of Structural Glued Laminated Timber
		Preservative treatments protect wood if outdoors fully exposed to the weather without roof cover, when in ground contact, when indoors in high humidity atmospheres, and for marine applications.
		Preservative treatment may or may not be required for certain installations where wood can be protected from decay with various construction details and connections maintaining an in-service moisture content of less than 20%.
		These preservatives, water soluble, are generally applied prior to gluing, then the wood is kiln dried and the members are glued to the required shape and size.

		Since arterial embalming first began in the Netherlands in the 17th century, anatomists, physicians, chemists, and embalmers constantly experimented with a variety of solutions and chemicals to produce an effective liquid preservative that would retard decomposition and, later, produce a life-like tint in the body's skin.
		Among its principal advantages are: it is cheap, it kills many micro-organisms to prevent the spread of disease, it aggressively destroys the enzymes responsible for decomposition, it reacts with proteins to form insoluble compounds that are resistant to decomposition, and it hardens and fixes the body's tissues quickly for positioning of the body.

	NCAMP-Poison Poles-Introduction
		Despite the fact that wood preservatives are some of the most deadly, ubiquitous and persistent chemicals known to the human race, the producers of these chemicals, treaters of the wood and end users of the treated wood products have all fought successfully to limit restrictions over a two-decade period beginning in the late 1970's.
		To maintain preservation of a pole over time, they are often pumped full of fresh chemicals, especially at the base where the wood meets the soil.
		While the environmental and public health problems associated with wood preservatives escalate and government fails to adequately regulate these highly toxic substances, the annual utility pole replacement rate of over three million poles is generating a disposal problem that can not be controlled.
