The analytical quality of published data on trace elements in food has previously been shown to be of a generally poor quality and, therefore, not always reliable. The responsibility for this problem is shared among authors, editors, reviewers, and p

Results for Cd, Cr and Pb at trace levels, in the same type of uncontaminated foodstuffs, often vary with several orders of magnitude, which normally is not the case for metals occurring at macro levels. In this paper we have been able to show that s

An analytical method for the determination of inorganic arsenic in fish samples using HPLC-ICP-MS has been developed. The fresh homogenised sample was subjected to microwave-assisted dissolution by sodium hydroxide in ethanol, which dissolved the sam

Certified reference materials (CRMs) are important tools in the quality control of food analyses. There are, however, many ways in which CRMs can be abused and misused. It can be due to ignorance, as well as to overuse of expensive materials. The maj

Wheat flour (sifted), wheat bran, and rye flour were sampled annually in several different areas in Sweden for 15 consecutive years (1983–1997) for a total of 105, 90, and 30 samples, respectively. These samples were analyzed for their content of C

The absorption and organ distribution of organic Cd from raw and broiled horse kidney was compared to that of CdCl2 at two dose levels (0.05 and 3 mg Cd/kg feed) in a feeding study in mice. The high Cd concentration in the horse kidney (raw 112 mg/kg
