OECD Guidelines for the Testing of Chemicals, Section 2 Test No. 230: 21-day Fish Assay A Short-Term Screening for Oestrogenic and Androgenic Activity, and Aromatase Inhibition
This Test Guideline describes an in vivo screening assay for certain endocrine active substances where sexually mature male and spawning female fish are held together and exposed to a chemical during a limited part of their life-cycle (21 days ...
Sediment Quality Assessment
Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.
Physiology of the Cladocera
The Physiology of Cladocera is a much-needed summary of foundational information on these increasingly important model organisms. This unique and valuable summary is based on the world's literature, including Russian research not widely available until now. It offers systematically arranged data on the physiology of Cladocera, assisting with explanation of their life and distribution, as well as discussion on directions of future research. Special expert contributions in genetics, immunology, and cytology round out the physiological chapters and provide comprehensive insight into the state of knowledge of Cladocera and its underlying mechanisms. Cladocera crustaceans make up a significant part of the natural communities and biological productivity of fresh waters. In recent decades, they have become globally studied for many purposes, including systematics, genetic, molecular, ecological and evolutionary biology studies. They are also used as "sentinel" organisms for assessing water quality and the environment. In addition, the genome of Daphnia (a genus within Cladocera) was recently sequenced and published, giving this system a much wider exposure. It has also led to a rapidly growing awareness of the importance of understanding physiological processes as they relate to evolutionary and ecological genomics and ecogenomic toxicology. Despite the increasing use of Cladocera in research and study, physiological background information on these creatures is fragmentary. Hundreds of unconnected publications have been accumulated on their physiology, and a synthesis and general representation of the literature has been much needed for the many researchers working with this organism. The Physiology of Cladocera stands alone as a valuable and comprehensive offering in this area for many researchers and students. - Collects and synthesizes from the worldwide literature the state of knowledge of cladoceran physiology - Forward-looking perspective incorporates information from the emerging technological worlds of genomics, cytology, chemical communication, and immunology - Provides foundational information on Cladocera physiology for researchers in various fields, including conservation and evolutionary biology, genomics, ecology, ecotoxicology, and comparative physiology
