The possibility of terrorists employing chemical, biological, or nuclear/ radiological (CBN) materials has been a concern since 1995 when sarin gas was dispersed in a Tokyo subway. Contingency planning almost exclusively involved detection. containment, and emergency health care for mass casualties. However, it is clear that even small-scale CBN incidents--like the recent spread of anthrax spores through the mail--can cause widespread confusion, fear, and psychological stress that have lasting effects on the health of affected communities and on a nation's sense of well-being. More emphasis therefore needs to be placed on indirect effects and on the medical, social, economic, and legal consequences that follow months to years afterward. To respond effectively to CBN attacks, a comprehensive strategy needs to be developed that includes not only emergency response, but also long-term health care, risk communication, research, and economic assistance. Organizing an effective response challenges government institutions because the issues involved--eligibility for health care, the effects of low-level exposure to toxic agents. stress-related illnesses, unlicensed therapeutics. financial compensation--are complex and controversial.  相似文献

A simple and rapid method for the analysis of carbohydrates in heroin samples by capillary electrophoresis utilizing a borate complexation method is described. Separations were performed using an uncoated fused silica capillary, 50 cm x 50 micro I.D. x 360 microm O.D. with an effective separation length of 9 cm. The system was run at 60 degrees C with an applied voltage of -8 kilovolts. Injection of each sample was for 1 sec at -50 mbar. UV detection was employed with the wavelength set at 195 nm. The background electrolyte consisted of 65 mM borate, pH 12.0. Samples and standards were prepared in the run buffer containing 2 mg/mL of mannose as an internal standard. Under these conditions a test mixture containing glucose, sucrose, lactose, mannitol and mannose as an internal standard was resolved within 5 min. The method was used to determine the concentration of carbohydrates in heroin seizure samples and synthetic heroin samples. The results were in good agreement with the reported values.  相似文献

The psychoactive properties of N,N-dimethyltryptamine (DMT) 1a are known to induce altered states of consciousness in humans. This particular attribute attracts great interest from a variety of scientific and also clandestine communities. Our recent research has confirmed that DMT reacts with dichloromethane (DCM), either as a result of work-up or storage to give a quaternary N-chloromethyl ammonium salt 2a. Furthermore, this was observed to undergo rearrangement during analysis using gas chromatography-mass spectrometry (GC-MS) with products including 3-(2-chloroethyl)indole 3 and 2-methyltetrahydro-beta-carboline 4 (2-Me-THBC). This study further investigates this so far unexplored area of solvent interactions by the exposure of DMT to other halogenated solvents including dibromomethane and 1,2-dichloroethane (DCE). The N-bromomethyl- and N-chloroethyl quaternary ammonium derivatives were subsequently characterised by ion trap GC-MS in electron and chemical ionisation tandem MS mode and by NMR spectroscopy. The DCE-derived derivative formed at least six rearrangement products in the total ion chromatogram. Identification of mass spectrometry generated by-products was verified by conventional or microwave-accelerated synthesis. The use of deuterated DCM and deuterated DMT 1b provided insights into the mechanism of the rearrangements. The presence of potentially characteristic marker molecules may allow the identification of solvents used during the manufacture of controlled substances, which is often neglected since these are considered inert.  相似文献

ABSTRACT

This paper examines why the support of independent local parties has grown substantially in the Netherlands. These are parties that run in municipal council elections, but do not run in elections at higher levels, specifically the national level. Such parties saw their support double in the Netherlands between 1986 and 2010. Parties of this type have also grown in other Western European states. This paper examines two possible explanations: declining political trust on the level of voters and, on the supply side, the rise of parties that are not rooted at the local level. The evidence shows that the rise of independent local parties reflects the rise of national political parties that do not run in many municipal elections. This article examines the case of the Netherlands, pooling five surveys from the 1986–2010 period.  相似文献

Commodity markets have changed significantly in the past two decades, with smallholders increasingly requiring robust market intelligence to understand and secure benefit from the new environment. This article explores the approach to, and lessons stemming from, an IFAD-financed market information service in Zambia. It finds that by locating the service within a pre-existing institution with legitimacy and credibility, the service has secured the interest of a wide range of actors, and has better enabled smallholders and traders to access and utilise relevant, up-to-date, and actionable information to shape decision-making. The article concludes by discussing the key considerations that shaped the institutional analysis, and the issues that will influence the financial sustainability of the service.  相似文献
