“…The 234.861 nm line that reportedly gave the most precise results was interfered by the emission of Fe + at 234.830 nm. 1,11 We studied the spectra of SRM 699 samples and blanks in the vicinity of the 234.861 nm line and found that the presence of Fe at a mass fraction of 91 mg g À1 AE 7 mg g À1 in SRM 699 (E1.5 mg g À1 in samples for the measurement) made accurate correction for the interference impossible. 8 No signal from Be in an SRM 699 sample was observed at the 265.045 line as the line is the least sensitive of the four.…”

“…et al 1991 (pumpkin) scopy for beryllium normally the 313.04 nm and 243.86 nm spectral lines are selected for measurement because of the higher line to background ratios and the lower detection limit. Schramel and Li-Qiang (1982) used three food type standard reference materials in their extensive study of the beryllium emission lines for spectral interferences. Prior to the determination, the samples were digested with ultra pure concentrated nitric acid at 1608C for 6 h in quartz tubes.…”

In an overall evaluation of the situation published by IARC in 1993, beryllium and beryllium compounds are identified as carcinogens to humans. This prompted the initiation of this study on beryllium which reviews the situation up to 1998 on the aspects: properties and applications, toxicity, analytical procedures for food and drinking water, reference materials, occurrence in food and drinking water and estimates of daily dietary exposure. Special emphasis is put on analytical aspects and levels of beryllium in food and drinking water.

“…Schramel and Xu (1982) determined beryllium in three reference samples by ICPS (inductively coupled plasma spectrometry); one sample was a BCR plant sample, BCR-61, Riparioides. Three samples of plants and one of milk powder are intended for determinations of Cd, Cu, F, Hg, Mn, Pb, and Zn.…”

“…The homogeneity of a Chinese sample, peach leaves, was tested by Tu andLeiser (1984a, 1984b). Schramel and Xu (1982) reported the beryllium content of a reference sample of riparioides, an aquatic plant. The sample of riparioides, undergoing certification at the time of publication, appears to be a sample from the Community Bureau of Reference with the number BCR-61, and the sample is so listed in the 1982 BCR catalog.…”

The use of geologic reference samples may have started in the last quarter of the 19th century after analysts in England, Germany, and the United States deplored the large variation in data obtained by different analysts for the same constitutent in the same sample. Early samples involved in cooperative analysis, also known as “round robins,” were mainly industrial or agricultural materials of economic value, or products derived from them. Data from some round robins were so diverse that “uniformity in analysis” was a part of early committee names. The first two geologic samples of the National Bureau of Standards were analyzed cooperatively. Samples for geology and geochemistry are classified as artificial samples or as natural materials of either economic or geochemical interest—the latter distinction not always possible. Artificial samples have been prepared in several substrates, and samples in other substrates may be limited only by the ingenuity of the analyst. The principal suppliers of samples of economic interest are discussed, by country, to show the range of samples prepared by organizations. Natural samples of geochemical interest are mentioned by sample type. Because of their intended use, some geochemical samples are restricted to analysts using specific techniques. Methods used for and precautions to be observed while preparing large or small rock samples are discussed. Excess grinding of small rock samples reduces the amount of FeO found in a rock analysis. Unavoidable contamination occurs when processing rocks in steel. Tungsten carbide, and some mechanical equipment, should be avoided. A review of the allied subjects of homogeneity of a sample, sampling errors, and size of the sample grains shows that we have reinvented the wheel since 1885. Methods used tc (1) test the homogeneity of samples, (2) eliminate outliers which some scientists reject repeatedly despite warnings of statisticians, and (3) estimate best values when the method for estimating should be part of the program for a sample are discussed. Calibration lines may be used to determine if “best values” in a series of several samples are really “best” and to furnish confidence limits for a single datum. The agreement of data by an analyst for a reference sample with data preferred by an issuing organization is usually described by one of several adjectives, a subjective procedure. A variation of a x2 method may be used if a producer specifies the exact number of data for the cooperative analytical program to be furnished by each analyst and then calculates the population estimates of the mean and standard deviation for an element in a sample. Because of the large increase in the number of reference samples of all types, a revised table listing samples that may be useful in geochemistry is included. It is not known if the samples, other than those of the U.S. Geological Survey, were collected in conformance with provisions of the Plant Pest Control Regulations of the U.S. Department of Agriculture, or of similar organizations in other ...
