Migration of Water-Soluble Oil Components in Some Soils of Bashkortostan

Abstract Field and laboratory experiments have been carried out to determine the toxicity to planktonic algae of crude oil, crude oil - water extracts and also selected oil components. Field experiments were performed in a half-acre pond. Localised spills of crude oil were confined within specially constructed floating cylinders with an attached collar. Three different effects of crude oil spills were noted - 1) certain species were inhibited in their growth 2) other species did not appear to be effected and 3) a number of species showed apparent stimulation following the spill. These results emphasize the great differences in response between species and suggest the actual planktonic composition of a water body of considerable importance in predicting the effects of an oil spill. In laboratory studies the toxicity of the water soluble components of crude oil only were tested. These extracts had a significant effect in increasing acidity of the water, which by itself, reduced algal growth. However, it was found that toxic factors were present, in addition to pH effects. There toxic factors or components appeared to be volatile. Tests with benzene, toluene and xylene - three water soluble crude oil components - showes them all to be toxic, with toxicity increasing in the order indicated.

Major Disadvantage ◽

Cell Organization

The extraction of lipids from tissues during fixation and embedding for electron microscopy is widely recognized as a source of possible artifact, especially at the membrane level of cell organization. Lipid extraction is also a major disadvantage in electron microscope autoradiography of radioactive lipids, as in studies of the uptake of radioactive fatty acids by intestinal slices. Retention of lipids by fixation with osmium tetroxide is generally limited to glycolipids, phospholipids and highly unsaturated neutral lipids. Saturated neutral lipids and sterols tend to be easily extracted by organic dehydrating reagents prior to embedding. Retention of the more saturated lipids in embedded tissue might be achieved by developing new cross-linking reagents, by the use of highly water soluble embedding materials or by working at very low temperatures.

Ultrathin Sections

The successful application of ferritin labeled antibodies (F-A) to ultrathin sections of biological material has been hampered by two main difficulties. Firstly the normally used procedures for the preparation of material for thin sectioning often result in a loss of antigenicity. Secondly the polymers employed for embedding may non-specifically absorb the F-A. Our earlier use of cross-linked polyampholytes as embedding media partially overcame these problems. However the water-soluble monomers used for this method still extract many lipids from the material.
