This study was conducted to determine brominated flame retardants (BFRs) in electronic products in view compliance with the Restriction of Hazardous Substances (RoHS) and initiated by activities for implementation of the Stockholm Convention. Brominated flame retardants (BFRs) are synthetic additives mainly used in electrical and electronic appliances and in construction materials. Total 16 plastic casing samples were tested for threshold levels of polybrominated ethers. According the XFR results, the concentration of cadmium, lead, mercury and chromium were found below than Maximum Concentration Value (MCV) of RoHS, while the concentration of total bromine was exceeded the standard limitations in the samples. Only 1 out of the 16 plastic samples contains DecaBDEs while Tetrabromobisphenol (TBBP-A) is the major brominated flame retardants. However by the presence of one sample the average concentration of DecaBDE was above the RoHS limit of 1000 ppm as found in studies in other countries.DOI: http://doi.dx.org/10.5564/mjc.v15i0.317 Mongolian Journal of Chemistry 15 (41), 2014, p27-32

X Ray

Lately, South Africa’s regulatory framework for electromagnetic medical devices has come under considerable pressure. In this article the legislative framework and regulatory infrastructure are scrutinized, by looking at how the legislature has given form to protective measures against ionizing radiation. Although the Hazardous Substances Act provides for effective protection against radiation, poor administration led to insufficient staffing levels, uncertainty about Regulations and licensing conditions and therefore undermines a sound radiation protection infrastructure. The legal basis of enforcing licensing conditions through a website without proper consultation with interested and affected parties is questionable and ineffective in controlling radiation levels. Effective and legal radiation control is possible by activating the National Advisory Committee on Electronic Products provided for in Regulation R326 published in 1979, but never implemented. The possible impact of annual quality assurance tests currently enforced through licensing conditions on the radiation dose of the population is not cost effective as new training and accreditation structures had to be created. The fact that generally more than 80% of overexposures are caused by human error is a clear indication that training of the daily users of X-ray equipment should be emphasized and not the training and accreditation of the technicians responsible for a single quality assurance test per year. Constructive engagement with the professional bodies involved in the medical use of X-rays through a National Advisory Committee on Electronic Products may be a cost effective solution for lowering radiation dose to the population.

Ambient Air Quality Standards

The Clean Air Act Amendments of 1970 provide the basis for a dramatic change in Federal air quality programs. The Act establishes new standards for motor vehicles and requires EPA to establish national ambient air quality standards, standards of performance for new stationary sources of pollution, and standards for stationary sources emitting hazardous substances. Further, it establishes procedures which allow states to set emission standards for existing sources in order to achieve national ambient air quality standards. The Act also permits the Administrator of EPA to register fuels and fuel additives and to regulate the use of motor vehicle fuels or fuel additives which pose a hazard to public health or welfare.National air quality standards for particulate matter have been established. Asbestos, mercury, and beryllium have been designated as hazardous air pollutants for which Federal emission standards have been proposed.

Analytical and computer models of false failure and undetected failure (error functions) were developed with tolerance control of the parameters of the components of the measuring technique. A geometric interpretation of the error functions as two-dimensional surfaces is given, which depend on the tolerance on the controlled parameter and the measurement error. The developed models are applicable both to theoretical laws of distribution, and to arbitrary laws of distribution of the measured quantity and measurement error. The results can be used in the development of metrological support of measuring equipment, the verification of measuring instruments, the metrological examination of technical documentation and the certification of measurement methods.

The construction of public participation has paid his dues. This is that in realizing development projects readily undergoing a failure that empowers people. Related in all process that deals with planning, implementation, the use of results and development monitoring. The rural infrastructure development program (PPIP) is development programs community empowerment. Where people have got to dive headlong in village development, especially physical development he purposes of this research is to find how the participation of the community in the Rural infrastructure development program (PPIP), Ngranget Village, Dagangan District, Madiun Regency. The kind of research is qualitative descriptive. In research, this is the population is the number of household heads involved in the delivery rabat concrete development in Ngranget village which consisted of 95 KK. The majority of informants interviewed in this research was 12 people. Was used in the study data collection method that is Technical Documentation interviews and data available for analysis namely described the results of research or data with a form of what is he got writer whether it is the results of the interviews, or result in appreciating documentation then investigated and the studies of the issue and. The result that the community participation in development in the village of rabat concrete Ngranget mind (planning), low participation in the form of energy high, participation in the form of expertise, quite low in the form of goods low, the form of money and participation is very low.
