Residue Reviews/Rückstandsberichte


Book Description

That residues of pesticide and other "foreign" chemicals in food stuffs are of concern to everyone everywhere is amply attested by the reception accorded previous volumes of "Residue Reviews" and by the gratifying enthusiasm, sincerity, and efforts shown by all the in dividuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being dis placed by newly developed ones more acceptable to food technologists, pharmacologists, taxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are of genuine concern to increasing numbers of governmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals per sisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.




Environmental Aspects of Construction with Waste Materials


Book Description

The concept of Sustainable Development, implicating the protection of soil and groundwater, the limitation of waste production and the re-use of soild waste materials is still the leading theme of WASCON '94. Although it is clearly recognized in most countries that products derived from solid waste materials can be applied as construction materials, research is still needed to assess various environmental problems.













Fly Ash


Book Description

Fly ash is a by-product of the combustion of coal and other waste materials. In recent years, there has been intensive research on fly ash because of the increasing demand for the recycling of industrial by-products to improve sustainability in manufacturing and infrastructure. This book presents some of the latest developments in the generation, characterisation, utilisation and environmental impacts of fly ash. Recent developments on the methods of collection and analysis of fly ash, and novel applications such as in geopolymers and recovery of resources from fly ash are included. The book is intended for professionals in research and academics, and students interested in materials and sustainability. The book consists of 17 chapters contributed by 42 authors. Each chapter ends with an extensive list of references for further information. The topics on fly ash have been grouped into the following three parts: Part 1: various sources, methods of collection, factors influencing collection efficiency, flow and hydrodynamic behaviours, methods of characterisation, physical, chemical, leaching and radiation properties, and extraction of metals from fly ash; Part 2: different technological initiatives on utilisation, applications in the construction industry, use as a supplementary cementitious material, alkali-activated binder, polypropylene composite materials, and behaviour of fly ash geopolymer concrete; and Part 3: health and environmental issues such as the effects on lung and heart, bioleaching for detoxification, ash from incinerated wastes, and lifecycle assessment of civil structures using fly ash.
