High-priority elements

To incorporate principles of metal speciation into established emission standards and quality criteria particularly for high-priority elements, in order to provide more realistic numeric values... 

Due to the direct contact of water with various species, the aqueous streams are laden with various compounds including methanol, non-process elements NPEs, and organic and inorganic species. In this problem, we focus on methanol as the pimary species in water. Methanol is classified as a high priority pollutant for the pulping industry. In addition, it may provide a source of revenue if properly recovered. 

Finally, a high priority should be given to studies linking N consumption and release with other elements. Studies following the pathway of multiple elements from food, to incorporation into zooplankton consumers, to their metabolic products wiU yield a wealth of information on biochemical nutritional requirements of zooplankton and the role of zooplankton in affecting the stoichiometry of nutrient cycling in the sea.

Apart from the classical envirotoxic metals (Cd, Hg, Pb) and the others mentioned above, the concept of new metals is now emerging as an environmental threat. Modem technology brings into extended use elements such as Am, Bi, In, Ga, La, Mo, Nb, Pd, Pt, Sb, Tc, Te and V, which are or will be distributed in the environment in a more or less uncontrolled manner. Very little is known about the envirotoxicity of these elements and thus toxicological data and risk assessment are a high priority. 

As the sampling sites with high responses of the test-battery are of most interest, the maximal elements are taken as priority elements, i.e. the equivalence classes 27, 33, 46, 47, 31, 95, 32, 9, 18. From this we conclude that a) the sites 27, 33, 46, 47, 31, 95, 32, 9, 18 are of specific importance, and b) the set of sites 27, 33, 46, 47 has the same profile of scores, thus, they may be remedied by the same methods, whereas the attribute profiles differ among all other priority objects. 

The chemicals in water may be inorganic elements or molecular species. Inorganic chemicals characteristic of groundwaters and surface waters are different. The importance given to the type of chemical contaminant present is dependent primarily on the potential health risk associated with it. Arsenic, barium, cadmium, and chromium are potentially carcinogenic elements. Mercury, lead, and selenium also have been proven to be toxic. These elements and their molecular species are high priority contaminants because their presence even in very small amounts could render the water toxic and nonpotable. 

The development and management of high quality technical information, particularly the safe upper and lower limit values, can be difficult and time-consuming but it is a vital activity. Without a sound information base, the quality of all of the other elements of the process safety program will always be in doubt. Therefore, it is critical that high priority be given to the development and maintenance of a high quality technical database. 

Event based indicators are lagging indicators which reflect experience in the past. Leading indicators are proactive indicators, and are as such often preferred. Barrier indicators are considered as leading indicators, and have as such been given high priority. They were not developed from the start of the Risk Level work, but were developed once the collection of event based indicators had been firmly established. The main emphasis has been placed on barrier elements that are associated with prevention of fire and explosion, but also... 

Recommendation 3.1 The Director, JSTO-CBD, should ensure that the development of a Culture of Collaboration is a high priority for all elements of the chemical and biological defense enterprise. Although information control requirements and contracting concerns have been stated as barriers on both sides to collaboration, these are issues that can and should be addressed. To ensure that the program delivers products based on the best S T available, the CBDP needs to find ways to partner with the broader scientific community and other federal agencies in areas relevant to chemical and biological defense. 

All the molecules in a DNA-encoded library are selected simultaneously. As shown in Ensemble Discovery and GSK s data analyses, a comprehensive view of SAR can be rapidly generated from the lines and planes formed in the SAR plot, high priority structural elements can be identified and applied to the next generation of library design, or to the synthesis of discrete compounds. In addition, a clear correlation between related structural elements with binding potency strongly validates the selection itself. 

These three elements new intelligence interpreted as suggesting a more serious threat, political opposition to projected defence plans and the policy and programme studies associated with any major arms control proposal - combined to present what was in defence establishment terms a pressing case for the upgrading of the US chemical warfare capability. They are reported to have led to a decision by the US Army in 1974 to allocate a high priority to its anti-chemical warfare preparedness and to initiate an extensive programme to improve the ability of the US Army to withstand chemical attack. ... 

Copper is an attractive metallisation element because of its high conductivity. It has been added to Al in low concentrations (AlSi(l%)—Cu(0.5%)) to improve conductive priorities. Selective, low temperature copper CVD processing, using copper(I) P-diketonate compounds, has been carried out (23). 

High productivity of dispersion fiows P ) for the major associated elements (Sn, Pb, Zn, Cu) that are typical for cassiterite-sulfide mineralization have been established for the Belaya Sopka Volcano-Plutonic Structure that made the like-named mountain range a high, first-priority target (Ananchenko 1982).
