Almost without exception all the accepted criteria for full cathodic protection of iron are based on a potential measurement. The various recommended practices published by the US National Association of Corrosion Engineers (NACE) give six criteria for full protection ". The current British Standard Code of Practice gives one. These are summarised in Table 10.3. Only the first three are useful the remainder are of dubious value or expressions of pious hope.

The US National Association of Corrosion Engineers (NACE) has published a test method for evaluating coatings. TMOl 105-2005 Test Procedures for Organic-Based Conductive Coating Anodes for Use on Concrete Structures . 

In 2001, influential groups such as the US Fire Retardant Chemicals Association and the US National Association of State Fire Marshals had at last started to consider ways to develop alternatives to test requirements based on FMVSS 302, or its equivalent ISO 3795.

No international or national databases were found that specifically collect data on ocular chemical injuries. There are individual publications detailing bums in general or chemical biuns (including eye and/or skin bums) in a region or country and case series from bum centers, hospitals, or groups of hospitals. Occupational bum data are usually regional in nature or are case series. National Poison Center databases such as the US American Association of Poison Centers National Poison Data System (NPDS) collect data on the annual number of eye exposures, but do not contain specific information... 

Folklore Spanish missionaries in South America regarded the flower of this herb as a symbol of Christ s passion, the three stigmas representing the nails, the five anthers the wounds and the ten sepals the apostles present. The herb was used in native North American medicine, especially by the Houma tribe, who put it into drinking water as a tonic. It became popular as a treatment for insomnia in the nineteenth century and was included in the US National Formulary from 1916 to 1936 (Bown, 2003 British Herbal Medicine Association, 1983 Giuenwald el al, 2002 Hutchens, 1973 Tierra, 1998). 

Human health risk assessment has often been dominated by the use of default assumptions and worst case analyses, based on the use of upper bounds on the dose from exposure instead of distributional characterizations of that dose. There are severe limitations associated with the use of default assumptions and upper bounds instead of distributions when detailed exposure and/or dose-response data are available. The US National Academy of Sciences, the USEPA, and many others have recognized the need for new risk assessment methodology (NRC, 1983, 1993, 1994 USEPA, 1992 CRARM, 1997). This need has promoted the development of new quantitative risk assessment methods that use probabilistic techniques, especially Monte Carlo simulation and distributional characterizations of dose-response, exposure, and risk. For these reasons, this paper uses a probabilistic approach. An indication of some of these new methods and the type of results they produce are given below.

Increased attention has been directed at sponses and children of agricultural workers. The US National Institute for Occupational Safety and Health (NIOSH) has prepared a review of children s exposures to environmental health hazards, including pesticides associated with parental occupation (NIOSH, 1995). 

In the United States, organizations such as the US Consumer Product Safety Commission and the National Association of State Fire Marshals have been instrumental in promoting fire safety of plastics in these applications. In many cases, it is not required by law that flame-retardant polymers be used. Rather, the UL seal is necessary for acceptance by consumers that the products meet the necessary requirements of fire safety.

Human health risk assessments with chemicals and other agents (biological, physical) typically follow a paradigm that involves four steps - hazard identification, dose-response assessment, exposure assessment, and risk characterization. The process was recommended by the US National Research Council in the 1980s, and is usually applied to a single agent and exposures associated with one or more routes (oral, dermal, inhalation). This has been more recently referred to as aggregate exposure and risk assessment. 

There are two interesting paradoxes concerning selenium. The first is that excess selenium is toxic however, at lower levels it is a protective agent against the toxicity of cadmium, methylmercury, arsenic, copper, and thalium. The second paradox involves carcinogenicity. The US National Cancer Institute found selenium monosulfide (administered orally) to be carcinogenic in rodents however, many epidemiological studies associate selenium intake with lower cancer rates in humans. Moreover, in...
