Abstract
A method, employing optical and x-ray emission, is described for the determination of all detectable elements in aquatic plants growing in the littoral zone of two lakes in Connecticut. The pondweed and the hornwort accumulate As. Comparative data are presented for the determination of this element by atomic absorption and x-ray emission. The chemical composition of some plants is shown as well as the distribution of the rare earths in various portions of the yellow water lily.
