The hydrophobic and hydrophilic organic fractions each accounted for about 50% of DOC of the secondary effluent samples. Hydrophobic acids were the largest group accounting for 42%, followed by hydrophilic acids and non-acid hydrophilic matters at 26% and 24%, respectively; nonacid hydrophobic matters at 8% were the smallest group.

The lipid peroxidation of S. maxima cultured in the presence of 4 to 100mg Se/L analysed showed that the contents of free radicals by EPR and malondialdehyde increased, of which the latter was the products of lipid peroxidation. These resulted in the decrease of the contents of liposoluble matter and percentage of polyunsaturated fatty acids, and the increase of percentage of saturated fatty acids. Using dimethyl sulfoxide , which was oxidized by OH·to form the stable and nonradical compound, methane sulfinic acid , as a molecular probe, we found that the contents of MSA from S. maxima growing in the presence of selenium were higher than those without selenium added, i. e. selenium in vivo was able to scavenge OH. in this alga.
