Temperature is one of the most important variables that determines the distribution and abundance of species (Cossins and Bowler 1987) and imposes critical limits on fitness. As a result of increasing metabolic rate, increasing temperature can increase the uptake and toxicity of contaminants by poikilothermic species, but may also increase rates of detoxification and excretion of toxicants (e.g., pyrethroid insecticides National Research Council of Canada [NRCC] 1987). Temperature extremes in themselves are stressful to organisms, causing induction of various stress proteins, which may be associated with fitness costs (Hoffmann et al. 2003).

Purge and Trap Using Capillary Cryofocussing A semiautomated, compact interface for time-resolved introduction of gaseous analytes from aqueous solutions into an ICP MS without the need for a full-size GC-oven was described [14]. Using this accessory, a method for the analysis of Fsh samples was developed and validated by the analysis of the Certibed Reference Materials (CRMs) DORM-1 and TORT-1 produced by the National Research Council of Canada (NRCC) [11],... 

The leading CRM producers in the world are NIST, the National Research Council of Canada (NRCC), and the International Atomic Energy Agency (IAEA). Information about CRMs produced by NIST can be found at the NIST website, www.nist.gov/srm/index.cfm... 

NRCC Metals Crystallographic Data File (CRYSTMET) is a database of crystallographic and bibliographic data on intermetallic phases. Also included are some hydrides and binary oxides. The database contains about 11,000 entries. It was started by Don T. Cromer at Los Alamos Scientific Laboratories, William Burton Pearson at Waterloo University, and Lauriston D. Calvert at The National Research Council of Canada (NRCC) and is currently maintained by the Canadian Institute for Scientific and Technical Information (CISTI). 

All instrumental analytical methods except coulometry (Chapter 15) require calibration standards, which have known concentrations of the analyte present in them. These calibration standards are used to establish the relationship between the analytical signal being measured by the instrument and the concentration of the analyte. Once this relationship is established, unknown samples can be measured and the analyte concentrations determined. Analytical methods should require some sort of reference standard or check standard. This is also a standard of known composition with a known concentration of the analyte. This check standard is not one of the calibration standards and should be from a different lot of material than the calibration standards. It is run as a sample to confirm that the calibration is correct and to assess the accuracy and precision of the analysis. Reference standard materials are available from government and private sources in many countries. Government sources include the National Institute of Standards and Technology (NIST) in the US, the National Research Council of Canada (NRCC), and the Laboratory of the Government Chemist in the UK.

The ISO Council on Reference Materials (REMCO) has identified more than 170 RM producers worldwide for the various fields of analyses. Two main bodies - the National Institute of Standards and Technology (NIST, USA) and the Institute for Reference Materials and Measurements (IRMM, European Commission, Belgium), successor of BCR (which is now a trade mark for materials produced by IRMM) - cover several fields and ensure long-term availability of the CRMs due to the large batches of materials produced. Other producers specialize in a particular field of interest, e.g., the National Research Council of Canada (NRCC, Canada), the National Institute for Environmental Studies (NIES, Japan), the IAEA Marine Environment Laboratory (Monaco), etc., specialize in marine analysis. The International Atomic Energy Agency (IAEA, Austria) mainly provides materials for nuclear measurements but also supplies RMs for non-nuclear analyses.
