It is hard to imagine a more concise summary of the prodigious work and voluminous publications in this field...This volume should be available to students at the undergraduate level, to those in law school, and to all seriously concerned about an extremely important problem. This review in Choice was just one of the many favourable comments that greeted the appearance of the first edition of this book when it appeared in 1977. Since then, there has been an explosion of interest in almost every aspect of research in environmental pollution. The aim of this new edition, however, remains the same i.e. to evaluate the global biological consequences of dispersal of trace elements, originally mined from localized limited deposits, in the environment. In treating the problems of metal contamination of the environment, the author considers the problems of environmental pollution involving metals and the problem of exhaustion of finite reserves of ores of metals, such as cadmium, copper, lead, mercury, nickel and zinc, as aspects of a single global problem.

<p>Presenting Scots as a separate language in its own right, and conscious of its long history, the author of this guide to grammatical and idiomatic usage resists the notion that Scots is merely a dialect or defective version of English. He provides working examples in the hope that writers, teachers and speakers will gather confidence and bring the language into serious use for the people of Scotland in the 21st century.</p>

<p>In this revised and extended edition, David Purves argues that the Scots language has lost prestige as a direct result of Scotland's loss of independence. As it has always been closely related to English, it has been possible to represent it as an incorrect or corrupt dialect, rather than the language of a people.\nThis book sets out the grammatical and idiomatic features of Scots, quoting examples from literature, proverbs, songs and colloquial speech to provide a resource for teachers and students of Scotland's linguistic heritage.</p>
