EC Directives


The discovery of chemical N2 fixation under ambient conditions is more compatible with a simple, complementary, low temperature and low pressure system, possibly operated electrochemically and driven by a renewable energy resource (qv), such as solar, wind, or water power, or other off-peak electrical power, located near or in irrigation streams. Such systems might produce and apply ammonia continuously, eg, directly in the rice paddy, or store it as an increasingly concentrated ammoniacal solution for later appHcation. In fact, the Birkeland-Eyde process of N2 oxidation in an electric arc has been  [c.92]

With the advent of organic optical polymers, an innovative photochemical approach to waveguide fabrication has been developed (67,68). Accordingly a chromophore, eg, a merocyanine dye, dissolved in or bound to a tbin film of an optical polymer is imagewise photobleached to tailor the index of refraction (at nonactinic wavelengths) of the polymer in precise fashion. Channel waveguides (67) and active waveguide devices, eg, directional couplers and interferometric intensity modulators (68), can be fabricated by this technique. Lasers, eg, Ar ion, are usually employed to effect photobleaching having high spatial precision. Kinetic studies indicate that one-photon processes dominate (69).  [c.392]

Enzymes are used as feed digestibiUty enhancers for chicken and pigs. They must comply with purity specifications comparable to food-grade enzyme specifications. European Community (EC) guidelines for the assessment of additives in animal nutrition are being revised to make them appHcable for enzymes. Upon completion of these guidelines, the regulatory status of feed enzymes will be estabUshed in EC directive 70/524/EEC.  [c.304]

Pesticides are potentially poisonous, noxious or polluting substances, and therefore the NRA is responsible for controlling and preventing pesticide pollution of water. Furthermore, the NRA is responsible for ensuring water quality meets standards set in a number of EC Directives, some of which specify values for pesticides.  [c.44]

Sources of land pollution include transport accidents, spillage during chemical handling, loss of containment from storage tanks, leakage and landfill of waste effluent. An appreciation of the processes governing retention, degradation and removal of pollutants and the behaviour of specific pollutants in soil are essential in devising coiTcct sampling and analytical strategies for assessing land contamination. Even soil itself varies in dynamics and composition from one site to another. Constituents include solid phase materials (such as complex mixtures of clays, minerals, organic matter), liquid aqueous phase of solutions (e.g. natural minerals, fertilizers, pesticides and industrial wastes) and gaseous phase components (e.g. oxygen, nitrogen, carbon dioxide, oxides of nitrogen, ammonia, hydrogen sulphide). The determination of toxic elements and organic substances in soils is a requisite of some EC directives as a means of controlling environmental pollution. Analyses are important when certain types of waste are recycled, e.g. by spreading sludge from water purification units on land, composting from household refuse. The choice of analytical method will be dictated by accuracy, sensitivity etc. Some key techniques are summarized in Table 10.10 and selected BS methods for monitoring soil quality are listed in Table 10.11.  [c.314]

Some substances defined in List I of EC Directive 76/464/EEC have had statutory EQSs set in daughter Directives. These have been transcribed into UK legislation via the Surface Water (Dangerous Substances) (Classification) Regulations of 1989 and 1992. Any exceedence of these statutory EQSs downstream of relevant discharges are reported annually to the DoE and action is taken to prevent further exceedences. The only List I pesticide with current agricultural approval is y-HCH and results indicate that a small number of sites fail to meet its EQS. Most are associated with polluted sites, but diffuse inputs are thought to be responsible for others.  [c.53]
