Abstract

A concise assessment of the risks to the environment posed by ethylene glycol. The chemical is produced in large quantities for use as a chemical intermediate as an antifreeze in engine coolants and as a de-icer on airport runways and aeroplanes. Most release to the environment is to the hydrosphere with use for the de-icing of runways and aeroplanes accounting for the largest local release to surface waters. Concerning behaviour in the environment studies show little or no capacity to bind to particulates and no mobility in soil. Evidence likewise indicates a low likelihood of bioaccumulation

Abstract

Diethylene glycol dimethyl ether (in the following called diglyme) is a colourless liquid with a slight pleasant odour. Due to its dipolar aprotic properties diglyme is used mainly as a solvent (semiconductor industry chemical synthesis lacquers) as an inert reaction medium in chemical synthesis and as a separating agent in distillations.This book evaluates the risks to human health and the environment of this chemical. Diglyme liquid or vapour is readily absorbed by any route of exposure metabolized and excreted mainly in the urine. The main targets of diglyme toxicity are reported to be the

Abstract

This book evaluates the risk to human health of ethylene glycol.Ethylene glycol is a colourless odourless sweet-tasting relatively non-volatile liquid. It is used in the manufacture of poly-ethylene terephthalate in natural gas processing and as an antifreeze agent. Available data from acute poisoning cases (humans) and repeated-dose toxicity studies (experimental ani-mals) indicate that the kidney is a critical organ for the toxicity of ethylene glycol in both humans and experimental animals.

Abstract

A concise assessment of the risks to human health and the environment posed by exposure to chloral hydrate a chemical used in human and veterinary medicine as a sedative and hypnotic drug. Chloral hydrate and its metabolites are also formed as by-products when water is disinfected with chlorine. Release to the environment occurs from wastewater treatment facilities from the manufacture of pharmaceutical-grade chloral hydrate and from the waste stream during the manufacture of insecticides and herbicides that use chloral hydrate as an intermediate. For the general public the most important sour

Abstract

PEGylated Protein Drugs: Basic Science and Clinical Applications describes the basic technologies and the major results obtained with the PEGylation technique, the covalent binding to proteins, peptides and small organic molecules of the hydrophilic and biocompatible polymer poly(ethylene glycol) to improve their therapeutic efficacy. The book results from the collaboration of recognized experts from academia and industry, working on various aspects of the PEGylation technology. The first chapters provide general information on the physicochemical, pharmacokinetic, immunogenic and toxicological properties of PEG and PEG-conjugates. The classical and more advanced chemical strategies for linking PEG to protein drugs are described as well as novel enzyme-catalysed approaches. Further chapters are devoted to important PEGylated products, namely PEG conjugates of enzymes, cytokines, antibodies or synthetic organic molecules already on the market or in an advanced state of clinical experimentation. Guidelines for the approval by the Health Agencies of these new nanomedicines are also reported as a last chapter. Therefore, this book may be a unique instrument for a thorough review of the strategy, advantages and limitations of all aspects of drug PEGylation as well as a stimulation for researchers to develop new exploitations of this technology. It is of interest to physicians, biochemists, pharmacologists and chemists.
