Data, environmental, quality assurance

It can be concluded that, in the field of RM certification, NAA represents a major analytical technique contributing significantly to the certification of element contents in environmental and biological RMs, as was also pointed out earlier (Dyb-czynski 1980 1995), and also provides the bulk of the hterature data on NIST SRMs (Gladney et al. 1987,1993). NAA also has a similar position in the field of geological RMs (Roelandts 1991). It possesses unique quality assurance and self-verification aspects (Becker 1993 Byrne 1993 Byrne and Kucera 1997), though these in-built features are rarely exploited in fuU at present. It should be reahzed that the advanta-...

The quantification of surfactants in environmental samples needs further development, particularly in so far as quality assurance of the analysis is concerned. Since the majority of the individual isomers and oligomers involved are not yet available as standards, quantification has to be based in part on external standards of commercially available mixtures. As this holds for both LC-FL and LC-MS analyses, both suffer from this shortcoming. Yet, samples analysed with both the methods have shown good agreement of resulting data.

Quality assurance to determine radionuclides in food and environmental samples ensures that the quality of data obtained is maintained at an adequate confidence level, and is objectively evaluated. Quality assurance includes quality control, which involves all those actions by which the adequacy of equipment, instruments and procedures are assessed against established requirements. 

Because environmental immunoassays are a relatively new technology, evaluation studies are an important step to acceptance and implementation. Many environmental analytical chemists are not familiar with the technology, thus, any immunochemical methods that are introduced must be well-characterized and provide data of known quality. Another complication is that many environmental immunoassays are developed by individuals not trained in analytical chemistry. Evaluation studies are essential to provide appropriate quality assurance and quality control measures. Frequently, the analytical... 

Nowadays it is generally accepted that laboratory proficiency testing schemes are an important quality assurance tool in environmental monitoring programmes. Apart from using validated analytical methods and internal laboratory quality control procedures, the regular participation of laboratories in interlaboratory comparisons is required to ensure the accuracy and comparability of data. 

A discussion of the quality of precipitation chemistry must include the analytical methods used as well as a description of the device used to collect samples. Most importantly, the quality of the data must be assured when assessing the impacts on the precipitationreceiving environmental system. Students of precipitation chemistry have used everything from glass bottles to baby bottle plastic liners to collect samples for analysis. Laundry baskets, staked to the ground, as well as fence-post mounted plastic bottles have also been...
