This book was released on 2004 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Test Guideline is designed to be used for assessing the effects of chemicals in soil on the reproductive output (and other sub-lethal end points) of the earthworm species Eisenia fetida or Eisenia andrei. Adult worms are exposed to a range of concentrations of the test substance either mixed into the soil or applied to the soil surface. The range of test concentrations is selected to encompass those likely to cause both sub-lethal and lethal effects over a period of eight weeks. The limit test corresponds to one dose level of 1000 mg/kg. This study includes the observation of unusual behaviour and morphology, the counting and weighing of the adult worms after the four primary weeks, the number of juveniles hatched at the end of the second 4-week period. The reproductive output of the worms exposed to the test substance is compared to that of the control(s) in order to determine the no observed effect concentration (NOEC) and/or ECx by using a regression model to estimate the concentration that would cause a x % reduction in reproductive output. The test concentrations should bracket the ECx so that the ECx then comes from interpolation rather than extrapolation.

Download or read book Soil Quality Avoidance Test for Determining the Quality of Soils and Effects of Chemicals on Behaviour written by and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: ISO 17512-1:2008 specifies a rapid screening method for evaluating the habitat function of soils and the influence of contaminants and chemicals on earthworm behaviour.The sublethal test is a rapid method that reflects the bioavailability of contaminant mixtures in natural soils and substances spiked into soils to Eisenia fetida and Eisenia andrei. The avoidance behaviour of the worms is the measurement endpoint of the test. This test is not intended to replace the earthworm reproduction test.Two different designs (a two section unit and a six section unit) have been developed and successfully applied. Both designs are applicable to either single-concentration (e. g. for assessing the quality of a field soil) or multi-concentration (e. g. for assessing the toxicity of a spiked chemical) tests. In both cases, the earthworms are allowed to make the initial choice on which compartment, control and a treatment [in the two section test vessel between right and left side; in the six section test vessel between the (3 + 3) alternating compartments], to enter.

Book excerpt: "Revised methods now recommended by Environment and Climate Change Canada for conducting biological test methods for measuring soil toxicity using earthworms (Eisenia andrei and Dendrodrilus rubidus) are described in this report. This revised version of Report EPS 1/RM/43 includes numerous updates such as: guidance for the collection, handling and testing of soils; the removal of two test species (Eisenia fetida and Lumbricus terrestris) and the addition of another test species (Dendrodrilus rubidus) specifically for testing soils from the boreal or taiga ecozones; revised test designs; and updated guidance for culturing and testing, testing with a reference toxicant, and for the statistical analysis of data. In addition, due to lack of demand and lack of sensitivity relative to the reproduction test, the 14-day acute lethality test has been removed as a test option herein. This revised report supersedes the first edition of this document published as Report EPS 1/RM/43 in June 2004 and revised in June 2007. This test method document provides detailed procedures, conditions, and guidance for preparing for and conducting each of two discrete biological test methods for measuring soil toxicity using earthworms (Eisenia andrei or Dendrodrilus rubidus). The test methods described herein are as follows: i) a 56-day test for effects on reproduction of adult earthworms exposed to one or more samples or concentrations of contaminated or potentially contaminated soil; and ii) a 48-hour test for avoidance of contaminated soil by adult earthworms"--Abstract, page iii.

Download or read book The Biology of Arid Soils written by Blaire Steven and published by Walter de Gruyter GmbH & Co KG. This book was released on 2017-07-24 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils have been called the most complex microbial ecosystems on Earth. A single gram of soil can harbor millions of microbial cells and thousands of species. However, certain soil environments, such as those experiencing dramatic change exposing new initial soils or that are limited in precipitation, limit the number of species able to survive in these systems. In this respect, these environments offer unparalleled opportunities to uncover the factors that control the development and maintenance of complex microbial ecosystems. This book collects chapters that discuss the abiotic factors that structure arid and initial soil communities as well as the diversity and structure of the biological communities in these soils from viruses to plants.

Download or read book Sustainability and Toxicity of Building Materials written by Emina K. Petrović and published by Elsevier. This book was released on 2024-02-10 with total page 693 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability and Toxicity of Building Materials: Manufacture, Use and Disposal Stages provides a review of toxicity impacts from building materials, including the consideration of the toxicity in the extraction and manufacture of the materials and eventual dismantling and disposal. This book also offers the potential to stimulate future developments in this area, both in terms of knowledge-building and methods for future research. With the increasing emphasis on sustainable construction, it has become important to better understand the impacts of common materials. Civil and structural engineers, postgraduates, researchers as well as architects will find this book to be useful in selecting sustainable building materials.While many building and furnishing materials are safe to use, in recent decades, some have had to be redesigned due to recognition that they contained problem chemicals like formaldehyde. Unfortunately, there is still limited understanding of the toxic impacts of many synthetic chemicals which means that the risks in this area are not well recognized. With increasing interest in using limited resources more sustainably, definitions of what is sustainable should be expanded to move from the focus on energy and carbon impacts to also include more explicit consideration of toxicity impacts. Examines toxicity in the extraction and manufacturing of materials Presents the short and long-term toxicity effects of natural and manmade building materials Guides readers in selecting building materials that have a positive impact on the health of occupants and the environment

Download or read book Advances in Terrestrial Isopod Biology written by Jasna ?trus and published by PenSoft Publishers LTD. This book was released on 2012-03-20 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terrestrial isopods (woodlice) are the only group of crustaceans fully adapted to life on land and with about 3,700 species known at present represent the largest suborder of Isopoda. They occur in almost any kind of terrestrial habitat, from littoral to high mountains, from forests to deserts, with some species adapted to live in subterranean environments and others secondarily having returned to water. Woodlice are particularly important from a biogeographical and an ecological point of view, since they have limited dispersal ability, are often endemic to small geographic areas, and are extremely diverse ecologically.ÿThey also represent en excellent model group of animals to study the physiological adaptations related to the transition from an aquatic to a terrestrial way of life. This special issue of ZooKeys includes a collection of 20 papers presented during the 8th International Symposium on Terrestrial Isopod Biology, which was held at Bled, Slovenia from 19th to 23rd June 2011. Contributions address a wide range of topics related to terrestrial isopods, such as systematics, biogeography, morphology, physiology, molecular biology, microbiology, and ecology. Two contributions are related to the state of the art and future perspectives on biomineralizations in crustaceans and ecotoxicology in soil fauna. This special issue will be of great value for anyone interested in the biology of crustaceans in general and of terrestrial isopods in particular, stimulating future research on this unique group of animals.
