Legislation prescribing

With regard to the first reason, it must be stressed that whereas each legislation prescribes explicitly that an industrial discharge should not affect the biota of the receiving waters, the... 

Substitution treatment first appeared in the EU in the late 1 960s in response to emerging opiate use. As such use spread, so too did substitution services, even though their practice varied — and still varies — considerably. Related legislation, prescribing practices and the overall organisation of substitution services also differ substantially within theEU. 

Where legislation prescribes arrangements for the provision of a health and safety policy, the requirement is usually conditioned by the size of the workforce. There is no logical reason why this should be the case. 

In order to maintain Class and to comply with international legislation a ship must undergo surveys at prescribed intervals. Ships such as tankers and bulk carriers must comply with International Maritime Organisation resolutions which require a Class Enhanced Survey Programme. This programme includes Special Surveys at five yearly intervals with close-up visual inspection and thickness measurements to be made at specified locations, the number of which increases with the age of the ship. 

The attributes required of a method usually include good sensitivity, low hmits of detection, and selectivity. It must be recognized that while low limits of detection will usually require good sensitivity, the latter, in itself, does not guarantee low limits of detection since these are often determined by the levels of interfering materials present and not the absolnte sensitivity of the technique. Low limits of detection allow the analyte to be determined at levels at or below those considered to be harmful or prescribed by legislation or at which it is found in a particular... 

There are other international standardising organisations, most notably the European Committee for Standardization (CEN) and AOACI, which follow similar requirements. Although CEN methods are not prescribed by legislation, the European Commission places considerable importance on the work that CEN carries out in the development of specific methods in the food sector CEN... 

It provides a stimulus and direction for innovation. Governments need not prescribe particular alternatives, but rather define criteria to guide the identification of alternatives. This will end the common practice of replacing a hazardous chemical under legislative pressure with a similar hazardous chemical that is less in the spotlight. 

The Medicines Act, together with the associated EU legislation and EU and ICH guidelines, should ensure that the safety of drugs made to the highest quality, the acceptability of their risk/benefit ratio and the promotion of correct information to the prescribers and consumers are the dominant features of the controls that operate today. 

Obviously, the risk of causing dependence is an important consideration in the therapeutic use of these drugs. Despite that risk, under no circumstances should adequate pain relief ever be withheld simply because an opioid exhibits potential for abuse or because legislative controls complicate the process of prescribing narcotics. Furthermore, certain principles can be observed by the clinician to minimize problems presented by tolerance and dependence when using opioid... 

In Australia there have been discussions as to how to make evidential breathalyzer measurements traceable to national or international standards. The amount of ethanol in a motorist is required by law to be less than a prescribed concentration, for many countries between 0.0 and 0.08 g per 100 mL blood. Recently there has been a move to change legislation to a limit of a given mass per 210 L of breath to avoid arguments about the blood/breath partition coefficient. As with any forensic measurement, metrological trace-ability is a key component of a successful prosecution. At present police buy standard solutions of ethanol in water from certifying authorities, with... 

Local legislation limits the availability and choice of opioids in many countries, but there can also be a reluctance to prescribe opioids for non-cancer pain due to the assumption that susceptible individuals may become addicted to these potent drugs through abuse. However, if opioids are prescribed on an individual basis with adequate support and education for the patients as well as their familes or carers, a great deal of unnecessary chronic pain and suffering can be prevented. But today there are still several unresolved clinical issues surrounding opioid use for which there is no data to construct a suitable policy.
