Dissimilatory Fe oxide reduction under anaerobic condition is a process which is an anaerobic respiration with Fe as the terminal electron acceptor. This anaerobic respiration showed important environmental significances. Dissimilatory Fe reducers can use diverse electron acceptors including many toxic heavy metals and metalloids such as Mn、Cr、Co insides Fe. So these toxic metals were detoxified or were immobilized reductively.

Model of animals were established by putting rats in a container with slippy inner wall and half-full of water in it, letting them swimming freely till died of being drowned. Each rat from different groups was killed by breaking its neck except drowning group, then BW and SO_2 was detected, and its chest was cut open rapidly, lung was taken out and weight was measured accurately to count lung coefficient. Its lung appearance was observed and lung tissue was fixed with formalin, which was made into pathology slices with HE staining, and pathology change of the lung tissue was observed;Expression of IL-8 and IL-10 in lung tissue was detected with Immunocytochemistry, and correlation between them was analyzed .

The second part was to test the appearance, ingredient analysis, surface potential, thermal conduction properties, and magnetism of the nano composite fluid prepared from the parameters. The experiment found that unoxidized particles, Ag, Cu, Fe, and Ni appeared round. If combined with oxygen in water as oxides, the nano particles would grow toward certain directions. In copper/iron nano composite fluid, FeO appeared cubic, Cu2O appeared coniferous. In silver/iron nano composite fluid, FeO was polygonal. In dielectric potential detection, the nano composite fluid was likely to aggregate and deposit, except for silver/iron set. In other sets, the pH of silver/cobalt nano composite fluid was 7, surface potential was 21.21mV; the pH for silver/nickel nano composite fluid was 6.5, surface potential was 21.04mV; the pH for copper/iron nano composite fluid was 7, surface potential was -30mV. The fluid particles of the three sets could all maintain suspension of 2 weeks or more. For thermal conduction, the silver/nickel, nano composite fluid showed the best thermal conduction. Under temperature of 30℃ fluid weight conduction of 0.4%, the thermal conduction increase was 26%. For magnetic detection, except for silver/iron nano composite fluid, the nano particles of other three sets were paramagnetic, and all four sets were soft magnetic nano composite materials.
