Occurrence, Formation and Fate of Organoantimony Compounds in Marine and Terrestrial Environmentsrs in the manufacture of semiconductors. This use is restricted to very controlled environments, hence there is no obvious route for organometallic antimony compounds to enter the environment. Anthropogenic emissions of antimony to the atmosphere have been calculated at 6 tonnes per year, while that

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(

Early on it became clear that organic matter that has been transformed into petroleum and gas was largely of marine origin and was deposited in marine sediments. A more

The supply of O. below the photic zone is dependent upon diffusion and advection. Anoxia normally occurs in enclosed basins where physical barriers (

Vapour-Particle Phase Interactions of Some Selected Persistent Organic Pollutants in the Marine Atmompounds are frequently transported within the environment at least partially in the vapour phase. The nature of the relationship between this vapour, the solid and liquid aerosol and the dissolved phase is therefore crucial to an understanding of how such chemicals migrate within the environment.

Determination of Organic Complexationme known that some interesting metals such as copper, zinc, iron, nickel, cobalt and probably more, participate in these reactions. This complexation changes the geochemistry of the metals by preventing them from being scavenged and thus increases their residence time in estuaries and the upper wate
