Arsenic metabolism in aquatic ecosystems,rsenic in the sea and in marine organisms has received much greater attention than arsenic in freshwater environments; higher concentrations generally mean greater ease of study and greater fears of toxicity to be stilled. The contents of this chapter dealing with marine and freshwater environments

Metal handling strategies in molluscs, metabolism occurring within cells. Many of these processes and associated metal-binding systems are common to a broad range of phyla, reflecting their evolutionary success in regulating the essential elements (e.g. Cu, Zn, Fe, Mn, Co) for physiological, biochemical and morphological purposes. The i

Phylogeny of trace metal accumulation in crustaceans,cumulate different trace metals to different degrees and accumulated concentrations vary greatly at tissue, organ and body levels (Eisler, 1981; Depledge and Rainbow, 1990; Rainbow, 1990a, 1993; Rainbow ., 1990; Phillips and Rainbow, 1993; Chapter 8). Whether an accumulated concentration is high or

Mechanisms of heavy metal accumulation and toxicity in fish,tic environment receives waste products from such activities and may be the final depository for these anthropogenically remobilized heavy metals. In order to understand the impact of heavy metals on aquatic biota it is important to characterize the mechanisms available for aquatic life to transport

Influence of ecological factors on accumulation of metal mixtures,g organisms. Most of them are based on analysis of single toxicants, despite the fact that under field conditions the biota is generally exposed to multicontaminant pollution. In addition to producing a direct response in biota, a toxic metal can also act by interfering with other metal ions or elem

Metals and marine food chains,food webs that route the supply, transfer and disposal of potentially toxic metals within ecological systems. Metals are transferred along the chains but they differ from the organic constituents of food in two main respects. Firstly, they can enter food chains directly from solution in sea-water by

Metal accumulation and detoxification in humans,ported to produce toxicity in humans (Goyer, 1996). Many metals are important as micronutrients and play an essential role in tissue metabolism and growth. They include Co, Cu, Cr, Fe, Mn, Ni, Mo, Se, Sn, V and Zn. Insufficient intake of these metals results in diseases or growth retardation. Other

Microorganisms and the biogeochemical cycling of metals in aquatic environments,ited works in this area: one by Summers and Silver (1978), which focused on the role of microorganisms in metal transformations (defined as those changes involving changes in valence or changes from inorganic to covalently linked organic forms), and the second by Gadd and Griffiths (1978), which rev
