Prediction of ecotoxicological behaviour of chemicals: Relationship between n-octanol/water partition coefficient and bioaccumulation of organic chemicals by alga

Prediction of Bioaccumulation Potential of Some Aromatic Hydrocarbons in Indicator Species of Ecotoxicity

“…3. The BCF values of the chemicals increase with increasing values for Kow, which is consistent with the results of other researchers (Neely et al1974, Veith et al 1980, Geyer et al,1984.The bar chart (Fig. 3) shows the uniformity in the results obtained from each equation for each compound.…”

Influence of Nitrogen Status on the Bioconcentration of Hydrophobic Organic Compounds to Selenastrum capricornutum

“…More speci®cally the lipid content of algae is known to be the major factor in¯uencing the bioconcentration of HOCs (Geyer et al, 1984;Manthey et al, 1993) and algal lipid status may vary considerably, both between species and for the same species, in relation to nutritional status. Bioconcentration of HOCs by algae has been described in several publications (Rice and Sikka, 1973;Urey et al, 1976;Casserly et al, 1983;Richer and Peters, 1993;Swackhamer and Skoglund, 1993;Stange and Swackhamer, 1994;Koelmans and Jime nez, 1994), but the level of knowledge about algae is limited compared to that available for ®sh.…”

Prediction of the environmental fate and aquatic ecological impact of nitrobenzene in the Songhua River using the modified AQUATOX model

“…At the end of two months, nitrobenzene residues in all organisms decreased to lower than 0.002 mg/kg, which could be explained by the lower biological concentration factors (BCF = 10-15), the relatively higher solubility (1,900 mg/L) of nitrobenzene in water, and degradability in biota (Geyer et al, 1984;Deneer et al, 1987;Patil and Shinde, 1988). Because of lack monitoring data, comparisons between predicted and observed values of nitrobenzene concentrations in organisms could not be conducted.…”
