Environmental bioassays

The use of a battery of environmental bioassays for the management of hazardous wastes is applied in the Czech Republic [176]. This battery of environmental bioassays has included representatives of producers, consumers, and destructors D. magna (possible substitution by D. pulex), acute, reproduction, chronic test Scenedesmus quadricauda S. capricomutum), as bottle test or in microwell plates Poecillia reticulate (Danio rerio), acute, chronic, embryolarval tests 5. alba (Lactuca sativa), germination test, 72 hours. 

Having briefly defined these four endpoints, I would like to ask, Are they related to known human disease Can they be measured quantitatively and Can they be measured with facility for inclusion in an overall plan for environmental bioassay Table I lists examples of gene locus mutations resulting in human disease phenylketonuria, histidinemia, Hartnup disease, and cvstinuria. Phenvlketonuria is...

If the purpose of an evaluation of mutagenicity of a complex mixture is to ascertain whether activity is present, it may suffice to use a simple extraction method. The extraction can be designed to remove and concentrate organics in general or to perform a preliminary separation in preparation for the isolation of specific classes of compounds. Organic solvents of choice are dimethyl-sulfoxide (DMSO), ethanol, benzene, methylene chloride, hexane, methanol, isopropanol, cyclohexane, or combinations of various solvents. Examples of such extraction procedures utilized as environmental bioassays of potential mutagens (carcinogens ) contained on or within particulate matter have been...
