Concentrations of polycyclic hydrocarbons in airborne particles in The Netherlands and their correlation with mutagenicity.
TLDR
The similarity of the profiles at the background coastal site and at the sites influenced by local sources was striking, and the PAH concentrations showed weak-to-moderate correlations with mutagenicity. Expand
Induction of nuclear anomalies (micronuclei) in the peripheral blood erythrocytes of the eastern mudminnow Umbra pygmaea by ethyl methanesulphonate.
TLDR
In a short feasibility study, the induction of nuclear anomalies in the peripheral blood erythrocytes of fish by the genotoxic compound ethyl methanesulphonate was detected and nuclear segments resembling the particles found in mammalian micronucleus tests were detected. Expand
Induction of sister-chromatid exchanges by alcohol and alcoholic beverages after metabolic activation by rat-liver homogenate.
TLDR
Samples of alcohol and alcoholic beverages induced SCEs in Chinese hamster ovary cells in the presence of rat-liver homogenate for metabolic activation and SCE tests with acetaldehyde indicate that SCE induction by alcohol is caused by formation of acetaldehyde. Expand
Monitoring the exposure of rats to 2-acetylaminofluorene by the estimation of mutagenic activity in excreta, sister-chromatid exchanges in peripheral blood cells and DNA adducts in peripheral blood,
TLDR
Mutagenicity in urine and faeces, collected during the first 24 h after treatment, was detected at 2-AAF doses of 1 mg/kg b.w. and higher, and this points to overloading of the metabolizing system which in combination with the enterohepatic circulation, may lead to an increased retention of 1-AAF in the body.

Application of polyurethane foam for sampling volatile mutagens from ambient air.
TLDR
It is lead to the provisional conclusion that no volatile mutagens could be demonstrated in ambient air sampled by the use of PUF as an absorbent, notwithstanding the clear-cut effects of the filter extracts and the presence of volatile PAH in the PUF extracts. Expand
Mutagenicity of urine and faeces after treatment of rats with known genotoxins.
TLDR
Results show that glucuronidated and non-glucuronidated mutagens can be demonstrated in faeces and urine up to several days after treatment of rats with genotoxic agents and it is concluded that examination of faecs and urine side by side enlarges the possibility of detecting exposure of the body to mutagen.

Mutagenicity of ambient aerosol collected in an urban and industrial area of The Netherlands.
To investigate the influence of the densely populated and heavily industrialized Rijnmond area of The Netherlands on the genotoxicity of the ambient aerosol, aerosol samples were collected atExpand
The role of mutagenicity testing in the ecotoxicological evaluation of industrial discharges into the aquatic environment.
TLDR
A detailed report on the ecotoxicological case history of the discharge from a nitrofuran factory demonstrates the role of mutagenicity tests in the evaluation of effluents. Expand
Induction of sister chromatid exchanges in Chinese hamster ovary cells by 5-bromodeoxyuridine.
TLDR
Results suggest that under the normal SCE-test conditions, e.g. 5-10 microM BrdU the majority of the spontaneous SCE are of the natural (non-BrdU) origin, and the remaining SCE seems to be a consequence of greater number of spontaneous lesions in the Brd U-containing DNA. Expand
Salmonella test: relation between mutagenicity and number of revertant colonies.
This paper describes a model that relates the actual effect measured in the Salmonella test, i.e., the number of revertant colonies, to the mutation rate induced by a stable test compound having noExpand
