Results of comparative research methods for arsenic content in meat samples of broiler chickens

The development of effective algorithms for optimizing the laboratory equipment base is one of the urgent tasks. Arsenic is classified as a toxicant of the highest hazard group; it is a highly toxic cumulative poison with a broad spectrum of action. The paper considers an assessment of the method for researching the content of arsenic in meat and meat products. The results of investigations (by the methods of photoelectric colorimetry and stripping voltammetry) on the operational control of the error using the method of additions and the assessment of precision were recognized as satisfactory. Comparative analysis of two methods of photoelectric colorimetry and stripping voltammetry in assessing the content of arsenic in samples of broiler chicken meat showed their relevance in the development of laboratory practice. 45.2%) over other ranges. The least registered sample results (1.1%) with the range of obtained data - 0.1-1.0 mg/kg.
