This volume is intended to provide an unbiased technical guide to those dealing with genetically modified organisms at the research or regulatory level. Reference to existing regulations is meant to bring into perspective the different oversight approaches at the national level and thus help the reader derive his/her own conclusions as to what may be optimal in a given situation. Chapter 1 - Biological Risk Assessment: An Editorial Overview of Some Key Policy and Implementation Issues. Chapter 2 - Public Perception of Biotechnology. Chapter 3 - Risk Assessment and Contained Use of Genetically Modified Microorganisms (GMMs). Chapter 4 - Safety in the Contained Use and the Environmental Release of Transgenic Crop Plants. Chapter 5 - Environmental Release of Genetically Modified Rhizobia and Mycorrhizas. Chapter 6 - Microbial Pesticides: Safety Considerations. Chapter 7 - Safety in the Contained Use and Release of Transgenic Animals and Recombinant Proteins. Chapter 8 - Safety Aspects of Aquatic Biotechnology.
