Genotoxicity is one of the parameters within the whole effluent environmental risk procedure, an effect-based procedure developed in the Netherlands to supplement classical substance-specific risk assessment of effluents. To implement the genotoxicit

Bioavailable concentrations of hydrophobic organic substances in aqueous tests often decrease as a result of (bio)sorption, volatilization, or degradation. In the present study, partitioning driven administering (PDA) is introduced as an approach to

Although the presence of hepatotoxins in surface and drinking water is regarded as an ecotoxicological and human health problem, limited knowledge exists on the fate of these compounds. Therefore the n-octanol/water distribution ratio (Dow) of the he

Sorption coefficients (Kps) of a series of polycyclic aromatic hydrocarbons (PAHs) were determined in two Dutch freshwater lake sediments to improve the insight into sorption in the aquatic environment. The influence of experimental factors, such as

Aqueous solubilities, n-octanol/water partition coefficients (K ow s), and Henry's law constants were determined for a range of polycyclic aromatic hydrocarbons (PAHs) using a generator-column, slow-stirring, and gas-purge method, respectively. The c

To determine whether or not biotransformation rates of PAH are influenced by induction of enzymes, fathead minnows were exposed to benzo(a)anthracene (B(a)A) in water for various exposure times followed by an elimination period. After exposure for be

The purpose of this study was to assess the suitability of applying equilibrium partitioning (EqP) theory to predict the bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) by earthworms when these are exposed to contaminated soils in the fiel

The two objectives of the present study are first, measuring sorption coefficients (Kp) of PAH in lake sediments. Secondly, comparing the Kp's of PAH in two lake sediments in order to establish if normalization on organic carbon content (OC) of the s

For naphthalene (NAPH) and 1,2,4-trichlorobenzene (TCBz), lethal body burdens (LBB) of 8 +/- 3.1 mmol/kg wet wt (ww) and 14 +/- 4.5 mmol/kg (ww), respectively, were determined in fathead minnow (Pimephales promelas). LBBs of both compounds were found
