Includes new sections on sampling and sample preparation; methods of instrumental analyses; and fully described specific micronutrient and heavy metal determination procedures. Appends information on standards and standard preparation, and conversion factors. References include general, analytical, and quality assurance texts. First published in 1976 or 1974, depending on the introduction or back cover. Annotation c. Book News, Inc., Portland, OR (booknews.com)
