“…Among the heavy metals detected in WSF are Pb, Cu, Zn, Cd, Ni, Cr, and V (Edema, 2006). This is in agreement with the statement of Kauss and Hutchinson (1975) that the WSF of crude oil contains metallic ions among other soluble contaminants. Botkin and keller (1998) stated that Pb, Cr and V are among metals that pose hazard to living organisms.…”

“…However, crude oil contains a very small soluble portion referred to as the water soluble fraction (WSF) Kavanu, 1964. The soluble constituents are dispersed particulate oil, dissolved hydrocarbons and soluble contaminants such as metallic ions (Kauss and Hutchinson, 1975). Non-hydrocarbon components of crude oil include polar components containing nitrogen, sulphur and oxygen (Westlake, 1982).…”

“…The water soluble fraction of crude oils has been found to reduce the growth rate of biomas turnover of some marcophytes (Gunlack and Hayes, 1977). Kauss and Hutchinson (1975) found that aquatic macrophytes population was reduced in the presence of water-soluble petroleum components. The inhibitory effects of petroleum components are known to be dependent upon the concentration of the crude oil as well as that of water soluble components (Shew, 1977).…”

“…That is, the microalga is still alive when it suffered from strong pollutant stress. The hydrophobicity of diesel causes dissolution and disruption of lipid containing structures of algal cells (Krauss & Hutchinson, 1975) such as the disruption of membranes; membranes of nuclei, mitochondria and chloroplast (Reynolds, 1987).…”

Temporal alterations of Nannochloropsis salina (Eustigmatophyceae) grown under aqueous diesel fuel stress

et al. 2005

The influence of an aqueous extract of diesel fuel was tested on growth of the marine eustigmatophyte Nannochloropsis (Monallantus) salina Hibberd. An increase in the concentration of the pollutant led to a decrease in growth rate as measured by optical density, with maximum effect observed (33% of control) at 100% aqueous pollutant. Spectrophotometric examination of cell viability (using Evan's blue dye) showed a significant negative effect of the diesel extract ( p ≤ 0.05, r = −0.92). Infrared spectra showed a slight change in the absorbance of contaminated compared with controlled cells. Proteome analysis (sodium dodecyl sulfate polyacrylamide gel electrophoresis -"SDS-PAGE") indicated that cell protein profiles depended on the pollutant concentration. Some of the resultant bands were characteristic to the pollutant concentration applied, indicating a distinct effect of the pollutant on the proteome structure. Iodine and toluidine blue dyes were applied using light microscopy to detect starch and mucilage, respectively. This indicated the presence of starch during all treatments, while the mucilage has been reduced. Transmission electron microscopy showed alterations to cell walls and membranes with different degrees of plasmolysis leading to a gradual increase in cell volume. However, the nucleus, the nucleolus and the pyrenoid remained unaffected. Similar results were obtained when the alga was cultured for 25 days in the 100% aqueous diesel extract indicating that long-term culture does not affect the degree of pollutant stress. Further, these cells recovered their normal appearance and characteristics within two days of being transferred to culture medium free of extract, indicating that N. salina shows a high tolerance to aqueous diesel fuel pollution.

“…was due to the higher concentrations of di-and triaromatic hydrocarbons in fuel oil. It has also been suggested that the degree of methylation of an aromatic hydrocarbon is directly related to toxicity in algae (Kauss and Hutchinson 1975;Pulich et al 1974). It was expected then, that the methylnaphthalene constituents of Aerotex would enhance the toxicity of this fuel oil distillate.…”

The algicidal properties of Aerotex 3470, a pesticide cosolvent in several fenitrothion formulations, have been investigated under controlled laboratory conditions. Aerotex (1–100 ppm) inhibited the growth of three unicellular freshwater algae (Chlamydomonas reinhardii, Chlorella pyrenoidosa, and Scenedesmus obtusiusculus) on agar plates and in liquid culture. Prolongation of the lag phase was directly related to Aerotex concentration. Algal cultures exposed for 1 h to Aerotex (1–10 ppm) had significantly reduced ATP levels. In all cases (agar, liquid culture, and ATP bioassays), Chlamydomonas and Chlorella were more sensitive to Aerotex than Scenedesmus.Electron microscopy demonstrated gross ultrastructural changes in Chlamydomonas treated for 1 h with Aerotex (5 ppm), including swollen mitochondria, disorganization of thylakoids, and crenulation of the cell membrane. Similar membrane damage was caused by 1-methylnaphthalene (5 ppm), a constituent of Aerotex.
