CS2 and COS occur in the atmosphere in significant amounts - CS2, 3.8-4.7 Tg S yr-1, COS, 2.7-3.5 Tg S yr-1 one-fifth to one quarter of these amounts are probably anthropogenic. Biogenic CS2 mainly originates in marine settings - anaerobic sediments (bacteria) and salt marshes with a role for Spartina alterniflora.6,10 Some terrestrial plants produce CS2 and tree roots are another source, usually after cutting or wetting. A tree of central America, Stryphnodendron excelsum. can be detected by its CS2 odor.10... 

For most people, BL is represented by the flash of the firefly or the phosphorescence that frequently occurs on agitating the surface of ocean water. Chemical excitation, luminescent reactions occurs in almost all zoological kingdoms (bacteria, dinoflagelates, Crustacea, worms, clams, insects, and fishes) except higher vertebrates BL is not found in any organisms higher than fish. In most cases this phenomenon occurs within specialized cells called photocytes [3-5], As shown in Table 1, BL occurs in many terrestrial forms but is most common in the sea, particularly in the deep ocean, where the majority of species are luminescent [6],... 

Atmospheric deposition is an important source of mercury for surface waters and terrestrial environments that can be categorized into two different types, wet and dry depositions. Wet deposition during rainfall is the primary mechanism by which mercury is transported from the atmosphere to surface waters and land. Whereas the predominant form of Hg in the atmosphere is Hg° (>95%), is oxidized in the upper atmosphere to water-soluble ionic mercury, which is returned to the earth s surface in rainwater. In addition to wet deposition of Hg in precipitation, there can also be dry deposition of Hg°, particulate (HgP), and reactive gaseous mercury (RGM) to watersheds [9-11]. In fact, about 90% of the total Hg input to the aquatic environment is recycled to the atmosphere and less than 10% reaches the sediments [12]. By current consensus, it is generally accepted that sulfate-reducing bacteria (SRB)... 

Tests show that the presence of soil reduces the toxicity of copper to the soil-dwelling nematode Caenorhabditis elegans copper toxicity to nematodes increases with increasing densities of bacteria and increasing concentrations of sodium chloride or potassium chloride (Donkin and Dusenbery 1993). Terrestrial isopods efficiently assimilate and store copper as detoxihed granules in the hepatopancreas this activity is in contrast to many species of marine crustaceans that are unable to assimilate, detoxify, or otherwise regulate copper (Weeks and Rainbow 1993). 

Phagocytosis is an important mechanism for the organism to rid itself of bacteria and pathogenic material, as well as cell debris and remnants of apoptosis. However, it can also provide a route for the uptake of pollutant particulate material. It is seen to be especially important in the incorporation of airborne particulate material, which often has serious health consequences (see Section 6.4). In terrestrial invertebrates, food is obtained either from particulate matter in the soil or from molecules dissolved in interstitial water. Most of these organisms have extracellular digestion, with nutrients and foreign material being absorbed by one or more of the routes available for transport across membranes, such as diffusion, channels or pinocytosis. There have been few studies to establish which route is taken.
