Abstract

"The main objectives of this study were: (a) to prepare a comprehensive review and evaluation of the literature pertaining to trace substances, with emphasis on their status in water supplies, health effects, and fate in treatment; ( b) to establish the methodology needed for measuring trace metals in trace organic substances; and (c) to determine the metal content of organic extracts recovered from surface, subsurface, and finished waters.

Raw and finished water was obtained at the Sedalia, MO, water treatment plant, and 5 sources were sampled (3 surface, 1 well, 1 plant-treated). The 0-CA* and SEM procedures were employed to recover trace organics (CCE-m, MCS/CAE-m, CAE-m, and SCE), and nitric acid digestion followed by atomic absorption analysis was used to measure trace organic-bound metals.

The methodology developed in this study for trace organic-bound metal determination was found to be successful; and with it the presence of 9 organically-bound metals (cadmium, chromium , cobalt, copper, iron, lead, manganese, nickel, and zinc) was established at concentrations in the ng/1 to μg/1 range, which constituted only a small fraction of the total metal content of the water. The need for further research in the trace substances field, especially the organometallics area, was shown with special attention required in the development of measurement and identification techniques and the evaluation of the toxic effects and fate in treatment of these substances"-- Abstract, p. ii
