The ability to detect toxicants in test soils and their waste extracts was investigated and the sensitivity of each bioassay was compared with regard to the tested material (soil vs. water extract from oil) and other test species. ...
As an important component of the ecologically relevant meiobenthic fauna, nematodes can be used for sediment assessments, with various assay tools ranging from single‐species toxicity tests to field studies. ...
Previous studies focusing on the relationship between the size or variation of ACRs to substance classes and QSAR‐models were often based on data for standard test organisms, such as daphnids and fish. For the present study, we performed acute and chronic toxicity tests with the nematode Caenorhabditis elegans for a total of 11 chemicals covering ...
Water samples were taken from mesocosms 24 hs post‐dosing for acute toxicity tests with embryos and larvae of Atlantic killifish (Fundulus heteroclitus) and the nematode Caenorhabditis elegans. Acute toxicity tests were also performed on Atlantic killifish with AgNO3, GA Ag‐NPs and PVP Ag‐NPs prepared in the laboratory with similar water. ...
The present study determined that a soil‐agar isolation method provides a highly efficient and less technically demanding alternative to the colloidal silica flotation method. Test soil containing C. elegans was arranged on an agar plate in a donut shape, a linear shape, or a C‐curve, and microbial food was placed outside the soil to encourage the nematodes to ...
A growth and reproduction test using the nematode Caenorhabditis elegans was recently standardized by the International Organization for Standardization. ...
A new toxicity test medium for C. elegans is presented. The test solution is designed so that it provides a better representation of natural soil pore water conditions than currently available test media. The medium has a composition that can readily be modified to allow for studies of the influences of a range of environmentally relevant ...
A ring test was carried out within the standardization process of ISO 10872 to evaluate the precision of the toxicity test for the nematode Caenorhabditis elegans. Eight different laboratories tested aqueous solutions of the reference substance benzylcetyldimethylammonium chloride as well as native sediments and soils for toxic ...
