Controlling persistent organic pollutants-what next?

Within the context of current international initiatives on the control of persistent organic pollutants (POPs), an overview is given of the scientific knowledge relating to POP sources, emissions, transport, fate and effects. At the regional scale, improvements in mass balance models for well-characterised POPs are resulting in an ability to estimate their environmental concentrations with sufficient accuracy to be of help for some regulatory purposes. The relevance of the parameters used to define POPs within these international initiatives is considered with an emphasis on mechanisms for adding new substances to the initial lists.

Implications of council regulation 793/93 on the evaluation and control of existing substances.

The European Union (EU) programme on existing substances makes provision for the delivery by industry of data on substances produced or imported above certain quantities which will be used by the Commission to facilitate selection of priority lists of substances for which risk assessments will be carried out. The substances comprise three subsets of the existing substances listed in the European Inventory of Existing Commercial Chemical Substances (EINECS) according to the respective deadlines for delivery of the data. The risk assessments are performed by the member states according to a commission regulation 1488/94 supported by guidance documents, may require further data delivery or performance of tests by industry and must conclude that the substance is either of no concern, of concern and risk reduction measures are appropriate, or require further data or testing to arrive at one of the other conclusions.

A method to assess the trainee profiles of medical students attracted to our physical medicine and rehabilitation residency training program.

A 35-item questionnaire was designed to assess the relative importance of various factors to medical students when ranking physical medicine and rehabilitation (PM&R) residency training programs. The questionnaire was used to assess the relative importance of the various factors to three groups of medical students: those who interviewed, those who matched and those who were listed on the match list of the UMDNJ-New Jersey Medical School (NJMS) Department of PM&R, as well as our current residents. Recipients were asked to grade selection factors based on a numerical scale: 1, extremely important; 2, very important; 3, important; 4, minimally important; 5, not important.

Current status of chairpersons in physical medicine and rehabilitation.

There are currently 77 academic departments, divisions or units of physical medicine and rehabilitation (PM&R) in the United States. The authors conducted a survey to develop a profile of the current chairpersons of PM&R, as well as to assess the short- and long-term needs of the field. The survey addressed basic demographic information as well as the level of formal training and/or experience in various management, patient care and academic areas.
