Raymond W. Yeungctory compounds, a large portion of which consists of humic substances (Thurman 1985). The term “humic substances” is usually used to refer to the organic matter that has been isolated from natural waters or from soils using well-defined techniques (Frimmel and Christman 1988; Huber and Frimmel 1994

Raymond W. Yeungility limitations and the formation of strong complexes. The very low assimilation of Cr(III) has led to its use as an inert tracer of ingested particulate matter to measure carbon assimilation in marine invertebrates (Wang et al. 1997). At low levels Cr(III) is an essential element for mammals. Cr(

Raymond W. Yeungalistic interpretations of past earth history hinge on understanding the behavior of organic matter in the ocean. It thus becomes important to better characterize the biogeochemical cycles that influence the production and preservation of organic matter in the sea. The term biogeochemistry emphasize

Raymond W. Yeungase molecules, adsorbate-surface complexes and/or the substrate surface itself. To separate single mechanisms, etching at normal and parallel incidence may be studied. Another type of laser-induced materials removal that is also included in this chapter is laser-induced ablative photodecomposition (
