Least restrictive environment

The Right to a Free, Appropriate Public Education in the Least Restrictive Environment Possible... 

A child with special needs must be given appropriate services either in the regular classroom or, only if necessary, in a different setting. If the services your child needs are not provided in your school system, the school district may have to pay for those services to be provided elsewhere. However, any services that CAN be provided within the district, within the child s regular school, and within the regular classroom SHOULD be so provided, so that the environment in which the child is taught is not any more restrictive than necessary. This is referred to as the requirement for the Least Restrictive Environment (LRE).

Averaging across regions with varying P accumulation rates undoubtedly imparts a relative error of at least 50% to the burial rate value derived here. Also, some restricted environments exhibit quite high but spatially variable P burial rates (e.g., phosphatic continental margin environments, Froelich et al. 1982 hydrothermal iron sediments, Froelich et al. 1977, Wheat et al. 1996). The areal approach is a more direct route to quantifying the burial terms in the P mass balance, and indicates that reactive P burial in continental margin sediments accounts for about 60% of the oceanic output, with deep sea sediments nearly equivalent as a sink. 

CCMHP is the current federal program providing coordinated, community-based, family-centered, cultmally competent, accessible, and least restrictive services for children and adolescents with serious emotional, behavioral, or mental disorders accompanied by functional impairment. Development of these systems of care is based on the premise that the mental health needs of children, adolescents, and their families can be met in their home, school, and community environments (Substance Abuse and Mental Health Services Administration, 1999). A variety of community agencies are involved, including mental health, child welfare, education, and juvenile justice. Funded service systems are tailored to the needs of individual children and adolescents and include evaluation and diagnosis. 

Chlordane-induced mortality of the long-billed curlew (Numenius americanus) has been documented at least four times since 1978, despite restriction of technical chlordane use since 1980 to subterranean applications for termite control (Blus et al. 1985). Death of these curlews was probably due to over-winter accumulations of oxychlordane of 1.5 to 5.0 mg/kg brain FW and of heptachlor epoxide at 3.4 to 8.3 mg/kg — joint lethal ranges for oxychlordane and heptachlor epoxide in experimental birds — compared to 6 mg/kg brain for oxychlordane alone and 9 mg/kg for heptachlor epoxide alone (Blus et al. 1985). Additional research is needed on toxic interactions of chlordane components with each other and with other chemicals in the same environment. 

If the application is for a biological system, wherein the objective is to isolate or quantitate a specific drug and its metabolite which is known, then the chemist can proceed to work with the compounds directly. In most cases, however, the chemist must be prepared to resolve the unexpected compound, which is not all that difficult, depending on the equipment available. The possibility that a thermal environment, such as GC, can initiate a reaction involving a labile drug or metabolite can be distressing, to say the least. Sample preparation usually includes some isolation technique which restricts classes of compounds. The need for sample cleanup will depend on the nature of the sample (see Section 12.3). The point here is that there will be some sample preparation as the first step in the analysis which will provide an initial "cleanup" of the sample. 

The approved uses for chlorinated chemicals have now become so restricted that for some of them at least they are now more likely to contaminate food as a result of their persistence in the environment rather than from their direct use on the food chain. A former pesticide in this category is hexachlorobenzene. There...
