Regulation of toxic metals in consumer products has significantly changed in the past decade, creating an increase in the demand for metals testing in a wide variety of materials. Industries dealing with child care products, toys, jewelry, packaging, and paints are especially concerned with the regulatory testing for toxic metals in their products. This book helps chemists, engineers, and attorneys concerned with testing materials for metals to comply with and enforce current government regulations. It covers various methods used for conducting tests, including X-ray analysis, mass spectrometric techniques, chromatographic techniques, and other methods (such as wet chemistry), and details the complications that ensue (i.e., the risk of failing an acceptable product) when test results are near the regulatory threshold.
