Diluting contaminants with outdoor air may increase the total quantity of supply air (including outdoor cur) Increase the proportion of outdoor air to total air, and also the improve air distribution. 

More recently, a range of other quality and safety issues have been recognised by consumers and now influence poultry meat and egg buying patterns and behaviour. Most importantly this includes (i) the routine use of antibiotics as growth promoters and curative medicines and the potential for development of transferable antibiotic resistance, (ii) risk associated with enteric pathogen (e.g. Salmonella and Campylobacter) and toxin (e.g. dioxin) contaminants of poultry products, (iii) the environmental impact of poultry production and (iv) the sensory and nutritional quality of eggs and poultry meat (Menzi et al., 1997 Hamm et al., 2002 Rodenburg et al., 2004 Horsted et al., 2005). 

The Pure Food and Drug Act was passed mainly in response to widespread public concern about contaminated meat and other food, but patent medicines with dubious contents and misleading labels were also a significant problem. Among its other provisions this law required that any narcotic ingredients in a patent medicine be disclosed, and prohibited unwarranted claims of curative powers. 

The curative powers of chicken soup have been known since it was prescribed as a remedy for the common cold in Ancient Egypt. In America today, chicken noodle soup is still a popular comfort food for treating the symptoms of the common cold and the flu. Given its healing powers, we should all be consoled by the fact that of the 240 food products tested by the Food and Drug Administration (FDA), chicken noodle soup was one of only five food products that were ml contaminated with synthetic chemicals. Other popular comfort foods fared much worse. 

Glyodin is a foliage fungicide with a curative effect against apple scab. It is effective also against cherry anthracnose and leaf spot. The pure compound is not phytotoxic, but the technical product damages certain plants. This phytotoxicity is attributed to the oleic acid contamination of stearic acid. 

Lake water is an accumulation of inver- and rain-water. As the waters of lakes ure kept in constant agitation both bv the wind and by the cur-they become to a great extent purified from organic contamination. 

In the United States, cholera was prevalent in the 1800s but has been virtually eliminated by modem sewage and water treatment systems. However, as a result of improved transportation, more persons from the United States travel to parts of Latin America. Africa, or Asia where epidemic cholera is (K curring. U.S. travelers to areas with epidemic cholera may be exposed to the cholera bacterium. In addition, travelers may bring contaminated seafood back to the United States foodbome outbreaks have been caused by contaminated seafood brought into this country by travelers. 

Hot-Air Test Tiibe Aging. In this method (ASTM D 865), specimens are heated in air but confined within individual test tubes. This prevents cross-contamination of compounds due to transfer of volatile materials (e.g., antioxidants, curatives, plasticizers, degradation products, and so on) from one sample to another. Thus, this test is free of some of the complications that can occur when numerous compounds are aged in the same enclosure. As before, hardness and tensile mechanical properties are measured before and after aging. 

In 1990, the Columbia River shoreline within the Hanford Site was surveyed for potential edible natural vegetation and samples were collected for radiological analysis. Table 5-21 shows results for samples of mulberry leaves and berries, and one sample of curly dock collected from the N Springs area. DOE initiated removal of all contaminated vegetation from the N Springs area in September 1990. Mulberry trees and other plants were removed and disposed of in the 200 Area burial grounds. 

Ayurveda, a traditional medical practice followed in India and other South Asian countries, is associated with medications that can contain lead. This is also the case with traditional or folk medications used in Middle Eastern, West Asian, and Hispanic cultures. The CDC has tracked specific cases of lead poisoning in the U.S. that involved Americans who consumed folk medications (CDC 2004). Lead is deliberately added to some of these medications because of the mistaken belief that it has curative properties. In some cases the source of lead is contaminated soil or older processing equipment. 

Slow cure may result from sulfur contamination. Add accelerator Viton Curative 20 to speed up cure, and eliminate contamination areas. If slow cure is not due to sulfur contamination, add Ca(OH)2. 

Care should be taken to ensure that the equipment is clean to prevent contamination that will react with the peroxide curative. 

Poor or logy cures may be caused by contamination of the compound with foreign accelerators, acidic materials such as clay in a dip, curatives on the surface of wrapping tapes, and so on. Always be sure that processing equipment is clean and free of any previously handled compounds and new or only tapes reserved for Thiokol compounds be used. Avoid acidic compounding materials such as clays or other low pH fillers or process aids. 

Yeast growth has been used as an assay-method for inositol (358, 431, 443). Woolley (443) examined the specificity of inositol by the yeast growth response (Hansen No. 1 strain of Toronto yeast) and for the curative effect on mice with an alopecia due to inositol deficiency (Table XXVII). The results were of the same type as with other growth factors apparently those compoimds are active w hich can readily form inositol, and any marked departure from this results in inactivity, e.g., quercitol, inosose, and quinic acid. Although the mytilitol was a natural product it was concluded by Woolley that its activity could not be ascribed to contaminating inositol.
